    Method and device for defrosting or deicing heat exchangers of the type in which a stream of warm, moist gas, such as warm, used ventilating air-so-called exhaust air-exchanges heat with a cooler medium, such as incoming fresh air, in a contact apparatus, and in which the two media flow through a large number of parallel layers separated from each other by thin walls.

    The invention relates to air conditioning equipment technology. An air-air heat exchanger is known, mainly for air-conditioning systems, comprising a housing with inlet and outlet connections for cold and warm humid air flows and alternating channels located in the housing for the respective flows II. The disadvantage of this heat exchanger is the low efficiency of heat exchange between the streams at low negative temperatures of the cold stream, which is caused by the freezing of the exchange surface from the side of the warm humid air stream. The purpose of the invention is to improve the efficiency of heat transfer between flows and low negative temperatures of the cold flow. The goal is achieved by the fact that the heat exchanger additionally contains a damper with a drive installed on the front side of the cold flow channels with the possibility of reciprocating motion and blocking at least one of the channels. The drive is made in the form of a reversible electric motor, a kinematically connected screw installed across the channels, and mounted on the screw with the possibility of moving a beam connected to the gate. The beam is equipped with two rollers, and the flap is made in the form of an elastic endless belt embracing them. In addition, at the ends of the screw installed limit switches of the electric motor, and on the beam - in turn interacting with them switch. FIG. 1 shows the heat exchanger, general view; in fig. 2 shows an embodiment of the flap; in fig. 3 - parallel installation of several heat exchangers with a single drive. The air / air heat exchanger contains body 1 with inlet and outlet connections 2-5 for cold and warm air.
    Air flow and air flow are located -} iijic in the body -1 alternating channels 6 and 7 for the respective flows. The heat removal additionally contains an 8-o slit installed on the front side of the cold-flow channels b with the possibility of reciprocating motion and blocking at least one of the channels.
    The device 9 is made in the form of a reversing electric motor Yu, a kinematically connected screw 3.1, mounted across the channels 6, and mounted on the screw 11 with the ability to move the beam 12 connected to the gate 8. The beam 12 is equipped with two rollers 13 and 14, and the gate 8 is made In the form of an elastic endless belt embracing them, in addition, end switches 15 of the electric motor 10 are installed at the ends of the screw 11, and the switch 16 interacting with them alternately at the beam 12.
    The heat exchanger operates as follows.
    The cold air flow passes through the pipe 2, enters the channels b, through the walls of which interacts with the warm and humid air stream that enters through the pipe 4, passes through the channels 7. The cold air stream heats up and the warm and wet air cools and both flow out of the heat exchanger, respectively, the pipes 3 and 5.
    At low temperatures below zero, cold air flows out of moisture and freezes on the surface, thereby deteriorating the efficiency of the heat exchanger.
    In this mode, the actuator 9 is turned on, which, rotating the screw 11, moves the beam 12, to which the valve 8 is attached on the rollers 13 and 14 to an endless belt. The valve 8, moving along the ends of the channels b, blocks access to the cold air. A warm air passing through the adjacent channels 7, due to its heat, thaws the moisture in the channels adjacent to the 8 cold air channels blocked by the damper. The valve 8 is constantly moving along the ends of the channels b and provides for ejection of all the channels 7. When the beam 12 reaches the end of the heat exchanger, the switch 16 interacts with the limit switches 15, the electric motor 10 changes the direction of rotation, and the valve 8 moves in the other direction.
    The proposed implementation of an air-to-air heat exchanger makes it possible to increase the efficiency of heat exchange at low negative temperatures of cold air flow, ensuring the constant removal of ice from the channels of warm, moist air flows.
