    [9] The present invention relates to a heat exchanger, and in particular, by improving the structure of the coolant pipe and the fins joined to the coolant pipe, the heat exchanger can easily drain the condensed water accumulated on the outer wall of the coolant pipe and the fin downward to achieve effective heat exchange. It is about the flag.
    [10] In general, the heat exchanger is a device in which the heat transfer medium transfers heat from a high temperature fluid to a low temperature fluid through a metal tube-type heat transfer wall having high heat conduction efficiency.The heat exchanger includes a heat exchanger such as an auto condenser and an air conditioner or a cooler. This is used for necessary products.
    [11] 1 is a perspective view and a plan view showing a heat exchanger according to the prior art.
    [12] The heat exchanger according to the related art has a refrigerant supply / discharge header 2 connected to the supply pipe 12 and the discharge pipe 14 so that the refrigerant is supplied and discharged after heat exchange, and the refrigerant supply / discharge header ( A refrigerant passage header (4) installed opposite to 2), and a plurality of refrigerant tubes (6) installed between the refrigerant supply / discharge header (2) and the refrigerant passage header (4).
    [13] The coolant supply / discharge header 2 is formed in a hollow cylindrical shape so that a supply pipe 12 through which a coolant is introduced is installed at one upper side thereof, and a discharge pipe 14 through which the coolant is discharged is installed at one lower side thereof.
    [14] In addition, the refrigerant supply / discharge header 2 is divided into an upper portion where the supply pipe 12 is connected and a lower portion where the discharge pipe 14 is connected, and is supplied into the refrigerant supply / discharge header 2. All the refrigerant is discharged after being circulated along the refrigerant pipe (6).
    [15] The refrigerant pipe 6 has a cross-sectional shape formed in a long ellipse shape in the horizontal direction and is horizontal and is installed between the refrigerant supply / discharge header 2 and the refrigerant passage header 4, and a plurality of the refrigerant pipes 6 are parallel in the vertical direction. Is installed.
    [16] In addition, a plurality of fins 8 are provided between each of the refrigerant pipes 6 to increase the heat transfer area of the refrigerant pipes 6 to improve heat exchange efficiency. It is formed into a continuous wave form and is joined between the upper surface and the bottom surface of each refrigerant pipe (6).
    [17] The refrigerant passing header (4) is formed in the same column shape as the refrigerant supply / discharge header (2), the upper and lower portions of the refrigerant pipe in the upper portion of the refrigerant supply / discharge header (2) The refrigerant moved to the refrigerant passage header (4) along (6) is moved to the lower side of the refrigerant passage header (4), and again exchanges heat through the refrigerant pipe (6) installed on the lower side to supply / discharge headers ( Pass through 2) and let it out.

Since condensate is generated on the coolant pipe 6 and the outer wall of the fin 6 because the corrugated fins 8 are formed with a continuous corrugation of the peaks and valleys, the condensed water accumulates on the upper surface of the coolant pipe 6 or the valleys of the fins 8. Damage to the heat exchanger may occur due to corrosion, etc., and heat exchange efficiency is also lowered.

    [27] In addition, the coolant supply / discharge header 52 is partitioned into an upper part and a lower part so that the coolant injected into the upper part of the coolant supply / discharge header 52 through the supply pipe is circulated along the coolant pipe 6. After the heat exchange, it is discharged to the outside along the discharge pipe 14 through the lower portion of the refrigerant supply / discharge header 52.
    [28] The refrigerant passage header 54 is formed in a hollow circular column shape like the refrigerant supply / discharge header 52 and is installed on the other side of the refrigerant pipe 56, and the inside thereof is formed as a space to supply the refrigerant. The refrigerant moved along the refrigerant pipe 56 at the upper portion of the discharge header 52 is moved downward in the inside of the refrigerant passage header 54 and again along the refrigerant pipe 56 of the refrigerant supply / discharge header 52. It is discharged to the outside through the lower part.
    [29] Figure 3 is a perspective view of the refrigerant pipe and the fin of the heat exchanger according to the present invention.
    [30] The refrigerant pipes 56 are formed in an elliptic shape having a long cross-sectional shape in a left and right direction, and a plurality of refrigerant pipes 56 are installed in parallel on a pair of vertical planes forming the front and rear surfaces of the heat exchanger, and the refrigerant pipes 56a installed on the front surface thereof. A predetermined space is formed between the refrigerant pipe 56b installed at the rear surface to facilitate drainage of the condensed water.
    [31] In addition, a plurality of fins 58 are installed in the spaces formed on the upper and lower surfaces of the refrigerant pipes 56 to increase the heat transfer area of the refrigerant pipes 56, thereby improving heat exchange efficiency. ) Is formed as a continuous waveform of mountains and valleys.
    [32] In addition, the fin 58 is installed on the upper surface of the pair of refrigerant pipes 56 installed at the front and rear of the heat exchanger, and the pair of refrigerant pipes 56 do not accumulate condensate in the valleys of the fins 58.
