    The roof type air conditioner is a vehicle air conditioner mounted on the roof of a bus or train that requires a large cooling system due to a large space for cooling. A refrigerant compressed in a compressor The heat of vaporization of the refrigerant absorbed by liquefying the gas by heat exchange with the outside air in the condenser, and then vaporizing it through heat exchange with the inside of the evaporator through an expansion valve or capillary tube. Cooling is performed. Accordingly, the roof type air conditioner is generally configured to be separated into a condenser unit in which a compressor, a condenser, and the like, and an evaporator unit in which an evaporator and an expansion valve are built.
    To this end, the condenser and its related parts and the evaporator and its related parts are arranged in each case to form one independent unit. That is, the evaporator unit U, for example, as shown in Figure 1, a plurality of circulating air in the vehicle on both peripherals in the case (C) mounted on the roof (R) to communicate with the interior of the vehicle (V) The blowers (B) are installed to communicate with the duct (D) of the vehicle, and a plurality of evaporators (E) for cooling the circulating air inside the blowers (B) are installed. Thus, the case C of each unit, e.g., the evaporator unit U, is composed of a plurality of partitions assembled together to install the evaporator E and its related parts therein, and the glass of high strength for weight reduction. It will consist of fiberglass reinforced plastics (FRP).
    Figure 2 schematically shows a conventional case (C) configuration of such an evaporator unit (U). It has a suction plate 1a at the center, a discharge hole 1b at both peripheries, and a base plate (1) on which components such as an evaporator (E) and a blower (B) are mounted. A wall plate 2 having a lower end joined to the base plate 1 to be wrapped, and a cover which is fastened to the upper end of the wall plate 2 by bolts (not shown) to block the exposure of components. (cover) It consists of a drain pan (4) bonded on the plate (3) and the base plate (1) to collect the condensed water generated in each evaporator (E).
    By the way, such a conventional evaporator unit case (C) is not only made of a large number of parts, but each part is assembled by hand by hand with a binder, so the manufacturing process is quite difficult and complicated, and there is a weak mechanical strength problem. In addition, when the base plate 1 and the drain pan 4 are bonded together, both deformations are severe, and relative joining positions are not accurately selected, resulting in a very high production failure rate. In particular, conventional components of the case (C) as shown in Figure 3, by using a predetermined open mold (open mold: 5) by using a liquid resin and fiber glass mat, such as a polyester resin for room temperature curing by hand It was manufactured by the so-called H, L, U (hand lay up) method of lamination and hardening, and the manufacturing tolerances between the parts were considerably large, which added to the above-described problems of assembly.
    SUMMARY OF THE INVENTION An object of the present invention is to provide a unit case of a loop type air conditioner which can reduce the number of components in view of the above-described conventional problems, and is easy to manufacture as well as to suppress a defective manufacturing rate as much as possible.
    In order to achieve the above object, the unit case of the roof type air conditioner according to the present invention has an evaporator and its related parts or a condenser and its related parts arranged on an upper surface thereof, and a base formed by pressing an FRP disc in a predetermined form. It is characterized in that it comprises a plate and a cover plate of a cap (cap) formed by press-forming the FRP disc in a predetermined form having a skirt (assembly) assembled by the base plate and the fastening means to surround the internal parts.
    According to one preferred feature of the present invention, the base plate and the cover plate, the FRP sheet is pressed between the two polyethylene film (polyethlene film) by impregnating the glass fiber in the resin mixture for high temperature curing blended with predetermined raw materials It is produced by the so-called sheet molding compound (SMC) method which is injected into a hot forming mold and molded under high temperature and high pressure.
    Accordingly, the present invention, the number of case components of the condenser unit and the evaporator unit is significantly reduced compared to the conventional, and the manufacturing tolerances between each component is minimized, so that the effect of improving the manufacturability of the roof-type air conditioner unit case, manufacturing defect rate and cost reduction, etc. Exert.

    Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.
    The loop type air conditioner consists of a condenser unit and an evaporator unit in which predetermined components are built in the case, but the internal structure of the case differs depending on the components included therein, and the basic structure of the case is the same. An example will be described.
    4 to 6, the illustrated configuration is, for example, the evaporator unit case C of the loop type air conditioner, and according to the features of the present invention, related parts such as an evaporator (E in FIG. 1) and a blower (B in FIG. It is composed of a cover plate 14 of a cap shape having a base plate 11 installed on the upper surface and a skirt 15 assembled by fastening means to the base plate 11 to surround the above parts.
    A suction hole 11a through which air in the vehicle is sucked is formed in the center portion of the base plate 11, and both peripheral portions discharge the circulated air cooled by the evaporator E to the duct in the vehicle (D in FIG. 1). A plurality of discharge holes 11b are formed. And between the suction hole (11a) and the both discharge hole (11b) of the base plate 11, the drain pan portion 12 for supporting the evaporators (E) from the lower portion to collect and discharge the condensate, respectively, are integrally formed. At the tip of the base plate 11, an approximately L-shaped flange 13 for fastening with the cover plate 14 is preferably formed.
    Accordingly, the flange portion 15a that wraps around the flange portion 13 of the base plate 11 is extended and bent to the front end of the skirt 15 of the cover plate 14.
    Therefore, in the present invention, after mounting the evaporator (E) and the blower (B), etc. on the base plate 11, the cover plate (14) is put on the upper portion of both flanges 13, 15a bolts (16) ) And the nut 17, or not illustrated, but the rivet may be configured by an extremely simple operation of fastening with a rivet.
    As described above, since the number of parts constituting the case C of the unit is composed of only two parts, the structure thereof is very simple as compared with the related art, and the manufacturing and assembling work is also significantly reduced. Particularly, in the case of the evaporator unit, since the drain pan part 12 is integrally formed, there is no need to separately manufacture and join the drain pan (4 in FIG. 2) as in the prior art. 11) It is fundamentally prevented in manufacturing defects due to deformation or shift of the joining position.
    The remaining reference numerals 18 and 19 are seal materials for maintaining the airtightness between the case C, the vehicle roof R, and the base plate 11 and the cover plate 14 of the case C.
    Meanwhile, the base plate 11 and the cover plate 14 of the unit case C of the present invention are manufactured by press molding an FRP disc of high strength for weight reduction. That is, as shown in Figure 7a the glass fiber 21 in the resin mixture 20 is mixed with a predetermined raw material consisting of unsaturated polyester resin for high temperature curing, a filler and various kinds of additives (light stabilizer, thickener, etc.) 1 type of hot forming consisting of the upper and lower molds 25 and 26 of the sheet-like FRP molding material 24 impregnated with a roller 23 between two polyethylene films 22 as shown in FIG. 7B. It is produced by the so-called SMC method which is put into a mold and molded at a high temperature and a high pressure to produce a predetermined form as described above.
    Accordingly, the case (C) of the present invention minimizes the manufacturing tolerances of each part to enable stable and accurate assembly, and the mechanical strength is greatly improved, and a plurality of parts are manufactured manually by an open mold and assembled together. Compared to the productivity and productivity can be maximized.
    As described above, according to the present invention, since the components constituting the case of the condenser unit or the evaporator unit are composed of only two, the structure thereof is very simple as compared with the conventional art, and the manufacturing labor is greatly reduced. In addition, the manufacturing tolerance of each part is minimized, so that stable assembly is possible without deformation of the case, and in particular, in the case of the evaporator unit, the installation position of the drain pan can be accurately selected. Therefore, the present invention can greatly improve the manufacturability and productivity of the roof type air conditioner, as well as having a very excellent effect that can significantly reduce the manufacturing defect rate.
