Embodiment Construction

[0021] The present invention will be further described below in conjunction with embodiment, but is not limited to the content on the description.

[0022] Most of the existing liquid cold plates are placed vertically when used, so the refrigerant will be affected by gravity in the vertical direction, and the current guide chamber of the cold night plate is relatively large, so the refrigerant liquid will be under the action of gravity Flow down to the bottom of the liquid cold plate, resulting in poor flow uniformity.

[0023] The invention discloses a heat exchange plate, comprising: a diversion cavity 10, a plurality of refrigerant inlets 20, diversion fins 30 and heat exchange channels 40, the diversion cavity 10 is arranged in the heat exchange plate; a plurality of refrigerant inlets 20 They are respectively arranged on the heat exchange plate, and a plurality of refrigerant inlets 20 are connected with the guide chamber 10; guide fins 30 are arranged in the guide chambe...

Abstract

The invention discloses a heat exchange plate with guide fins and a battery PACK box. The heat exchange plate includes: a flow guide cavity, the flow guide cavity is arranged in the heat exchange plate; a plurality of refrigerant inlets , a plurality of the refrigerant inlets are respectively arranged on the heat exchange plate, and a plurality of the refrigerant inlets are all communicated with the guide chamber; guide fins, the guide fins are arranged in the guide chamber Inside, the guide fins divide the guide cavity into a plurality of guide sub-cavities, and the guide sub-cavities correspond to and communicate with the refrigerant inlets one by one; heat exchange channels, the heat exchange channels are set In the heat exchange plate, all the guide sub-chambers communicate with the refrigerant inlet end of the heat exchange channel. The guide fins of the heat exchange plate of the present invention can hold part of the refrigerant liquid and limit it in the guide sub-cavity to avoid the influence of gravity, so that the refrigerant liquid can be more evenly divided into the heat exchange channel, Improve the uniformity of refrigerant liquid flow.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a heat exchange plate with guide fins and a battery PACK box. Background technique [0002] The power battery has a serious impact on the working performance of electric vehicles. In the high-temperature fast charging and discharging mode, the battery needs to be cooled quickly, and the low-temperature environment needs reasonable preheating to ensure that the battery is at a suitable temperature. According to the performance of the battery, if the design of the PACK box can ensure that the temperature is stable at 15°C to 45°C, it can perform best in all aspects, but the ambient temperature we face is usually -30°C to 55°C, and neither air cooling nor natural cooling can To meet its use conditions and requirements, it is necessary to apply liquid cooling technology. Liquid cold plate is the most common way of liquid cooling technology. In the design of liquid cold plate, flow...
