Heat exchange device, heat exchange system comprising heat exchange device and vehicle

Abstract

The invention provides a heat exchange device, a heat exchange system comprising the heat exchange device and a vehicle, and belongs to the technical field of vehicle heat exchange. The heat exchange device comprises a first flow guide plate, a plurality of heat exchanger plates, a second flow guide plate, a throttling plate and side plates. The first flow guide plate is provided with a first medium inlet, a first medium outlet and a second medium inlet; the plurality of heat exchanger plates are mounted on the first flow guide plate, and a first medium inflow channel, a first medium outflow channel, a second medium inflow channel and a second medium outflow channel are arranged; the second flow guide plate is mounted on the heat exchanger plates and is provided with a second medium outlet, a first medium inlet and a first medium outlet; the throttling plate is installed on the second flow guide plate and provided with throttling holes; and the side plates block the edges of the first flow guide plate, the multiple heat exchanger plates, the second flow guide plate and the throttling plate to form a plurality of first medium plate channels and second medium plate channels which are arranged alternatively. The problem that use of an air conditioner is affected due to control lag of an existing heat exchange device is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle heat exchange, in particular to a heat exchange device, a heat exchange system including the heat exchange device, and a vehicle. Background technique [0002] At present, the automotive industry is developing in the direction of electrification, and battery thermal management has become the top priority of thermal management. The battery temperature must be kept within a certain range, generally between 25°C and 40°C. Currently, the main components of battery cooling are heat exchangers, mainly including expansion valves and plate heat exchangers. Expansion valves are mainly thermal expansion valves and electronic expansion valves, both of which have certain problems: the electronic expansion valve can control the opening of the expansion valve, effectively adjust the flow of refrigerant according to the different modes of the air conditioner, and achieve precise control of the temperature of the...
