Problems solved by technology

The evaporators used to cool the battery packs all adopt a single-core structure and are arranged outside the battery pack. An air duct is added inside the battery pack so that the cold air can effectively enter the inside of the battery pack and cool the battery pack. The cold delivery path of the device is long and the cooling loss is large
If the single-core evaporator assembly is placed in the battery pack shell, due to the limited space in the battery pack shell, the single-core evaporator assembly often cannot meet the cooling capacity required by the battery pack. The existing evaporator uses a heat exchange core In the way of series connection, there are problems of poor temperature consistency and poor cooling effect

Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The evaporator assembly includes a refrigerant pipeline assembly 2 and a plurality of heat exchange core assemblies 1. The refrigerant pipeline assembly 2 includes a refrigerant inlet pipe 21 and a refrigerant outlet pipe 22. The output ends of the refrigerant inlet pipe 21 are divided and connected separately. The refrigerant inlet 141 of each heat exchange core assembly 1, the input end of the refrigerant outlet pipe 22 is divided and respectively connected to the refrigerant outlet 142 of each heat exchange core assembly 1, each heat exchange core assembly 1 is connected in parallel to the refrigerant pipe On the road assembly 2. The parallel structure design of the heat exchange core is adopted, and the temperature of the left and right heat exchange cores is uniform. The refrigerant between the left and right heat exchange cores i...

Abstract

The invention provides an evaporator assembly and an evaporator assembly for an electric car battery pack. The evaporator assembly comprises a coolant pipeline assembly and a plurality of heat exchanging core body assemblies, wherein the coolant pipeline assembly comprises a coolant inlet pipe and a coolant outlet pipe, the output end of the coolant inlet pipe is divided and connected with a coolant inlet of each heat exchanging core body assembly, the input end of the coolant outlet pipe is divided and connected with a coolant outlet of each heat exchanging core body assembly, and each heat exchanging core body assembly is connected with the coolant pipeline assembly in parallel. The evaporator assembly is large in heat exchanging area and good in temperature consistency.

Description

technical field [0001] The invention relates to a cooling device, in particular to an evaporator assembly. Background technique [0002] As one of the core components of electric vehicles, the battery pack faces disadvantages such as life attenuation and thermal instability in high-temperature discharge. The temperature control range of the battery pack directly determines the safety performance, service life and driving range of the battery pack. Therefore, it is particularly important to develop a safe, efficient and uniform cooling device for power battery packs. The evaporator is an important device in the cooling system of the battery pack, but the structure, size and other conditions corresponding to the cooling capacity required by the evaporator cause it to be mainly arranged outside the battery pack. [0003] The structure of the existing evaporator assembly is generally a single-core assembly, which is composed of left and right headers, fins, flat tubes, refriger...
