Heat exchanger which is convenient to disassemble and used for refrigeration

Abstract

The invention relates to a heat exchanger which is convenient to disassemble and used for refrigeration; a ring of rigid plates are added at the periphery of an air outlet of an evaporator which is provided with the heat exchanger used for refrigeration, and are glued at the periphery of the air outlet of the evaporator by glue; rectangular closed hole rubber sponge is compacted between the plates and the roof skin of the bus so as to achieve waterproof and sealing effects and overcome the defects that the sealing mode of the air outlet of the overhead part of the refrigerating equipment of the bus is the mode of sponge strips and sealing glue and is not easy to disassemble and assemble and consumes fuel; the two ends of the connecting joint of the evaporator and a condenser are added with two stop valves; the two ends of the connecting joints of the condenser and a high-pressure pipe are added with two stop valves; the two ends of the connecting joint of the evaporator and a low-pressure pipe are added with two stop valves, thus better storing the refrigerants in the pipeline. The heat exchanger is also provided with a condensate atomizer, and utilizes the condensate again, thus improving refrigeration effect; therefore, the heat exchanger has convenient disassembly, saves fuel consumption and has wide application value.

Description

technical field [0001] The invention relates to a vehicle-mounted refrigeration air conditioning device, in particular to a heat exchange device for refrigeration that is easy to disassemble. Background technique [0002] Generally, the passenger car refrigeration air conditioner is composed of a refrigeration compressor installed on the passenger car chassis and a heat exchange device installed on the top of the passenger car. The top heat exchange device is fixed on the passenger car roof, fixed with bolts and bonded with adhesive In order to prevent rainwater from pouring into the interior of the car, the refrigeration compressor and the heat exchange device are connected by pipelines to transport the heat exchange medium, and there are water pipes connecting the heat exchange device to the chassis of the bus to discharge the heat exchange device. Condensed water in the air. [0003] However, the weight of the top heat exchange device for passenger car refrigeration is a...

Problems solved by technology

[0003] However, the weight of the top heat exchange device for passenger car refrigeration is about 250Kg, and in temperate and subtropical regions, the time of using refrigeration and air conditioning in a year is relatively short, generally only 3-5 months, and passenger cars must be used in places where refrigeration and air conditioning are not used.
