Description

A high-efficiency heat pump air-conditioning thermal management integrated module

technical field

The present disclosure relates to the field of vehicle thermal management, in particular, to an integrated module for thermal management of a high-efficiency heat pump air conditioner.

Background technique

With the development of electric vehicle thermal management technology, thermal management centered on waste heat recovery low-temperature heat pump air conditioners is developing rapidly. A major feature of waste heat recovery low-temperature heat pump air conditioners is that there are many valve bodies, many refrigerant circulation circuits, and the entire air conditioning pipeline is complex. . More valve bodies and complex pipelines take up a lot of space in the front compartment of the vehicle, and more pipelines and interfaces also bring risks such as leakage and pressure loss. Therefore, some leading enterprises of electric vehicles have carried out the development and design of valve body integration.

The solution of prior art 1 uses 4 solenoid valves, 3 electronic expansion valves, and 3 one-way valves to realize the waste heat recovery function. The valve body is on the pipeline, directly connected, and the air conditioning pipeline is complicated. The scheme utilizes the waste heat of batteries and motors, and recovers waste heat through LCC to heat the passenger compartment heat pump at low temperatures. However, the heat pump cannot heat the battery, and the battery still needs to be heated by a water heater.

The scheme of prior art 2 adopts 6 solenoid valves, 3 electronic expansion valves, and 5 one-way valves to realize the cycle switching of refrigerant, and integrates the above valve body and chiller through an integrated module; the system is integrated and lightweight. Simplify the space layout of the vehicle, reduce the messy front warehouse pipeline; shorten the refrigerant pipeline and reduce the pressure loss. However, the technical solution of the second prior art has the problem that the battery is directly cooled and heated, and the temperature difference is relatively large in the thermal management of the battery.

Therefore, one or more methods are needed to solve the above problems.

It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.
