Problems solved by technology

[0004] The HVAC module in the existing automotive air-conditioning system, because the two core components of the evaporator and the heater are arranged independently, the overall volume is relatively large and takes up a lot of space, resulting in a complex structure, large volume, and heavy weight of the entire module. The conversion and control of functions are also relatively complicated, which makes the existing HVAC module production process more complicated and the production cost higher

Abstract

The invention belongs to the technical field of heat exchangers and discloses a heat exchanger. The heat exchanger is formed by stacking multiple heat exchange plates. A first groove and a second groove are formed in each heat exchange plate, a refrigerant flow path is formed at the first grooves of every two adjacent stacked heat exchange plates, and a heating flow path is formed at the second grooves of every two adjacent stacked heat exchange plates. The refrigerant flow paths are communicated in sequence to form a refrigeration cycle zone, and the heating flow paths are communicated in sequence to form a heating cycle zone. By forming the two grooves in each heat exchange plate, the refrigeration cycle zone and the heating cycle zone which are mutually independent can be formed after the heat exchange plates are stacked and mounted, one heat exchanger achieves the functions of an evaporator and a heater at the same time, the production cost is reduced, and the heat exchanger can replace the conventional evaporator and heater and is applied in an HVAC module, so that the structure of the HVAC module is more compact, the layout assembly is more flexible and simpler, and productsare lighter.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a heat exchanger. Background technique [0002] The air conditioning system on a car generally includes five functions of cooling, heating, defrosting, defogging and ventilation. Among them, the HVAC module arranged in the passenger compartment is the core component to realize the above functions. Generally, in order to realize the above functions, two independent heat exchangers are arranged in the HVAC module: an evaporator and a heater, which are respectively used to realize the cooling function and the heating function. Through the two basic functions of cooling and heating, functions such as defrosting and defogging can be further derived. [0003] At present, the evaporators and heaters widely used in automotive air-conditioning systems are all aluminum brazed structures, and the overall structure is relatively close. Among them: the air flows outside the evapora...
