Embodiment Construction
[0039] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0040] figure 1 It is a schematic diagram of a battery box direct cooling system provided by an exemplary embodiment. Such as figure 1 As shown, the battery box direct cooling system includes a compressor, a condenser, a battery box evaporator and coaxial pipes. The direction of the arrow in the figure indicates the flow direction of the refrigerant in the pipeline. The coaxial pipe has a first coaxial pipe a and a second coaxial pipe b inside. A first coaxial pipe a is connected between the outlet of the condenser and the inlet of the battery box evaporator. A second coaxial pipe b is connected between the outlet of the battery case evaporator and the i...

The disclosure relates to a battery box direct cooling system and a control method thereof, a medium and electronic equipment. The battery box direct cooling system comprises a compressor, a condenser, a battery box evaporator and a coaxial tube, wherein the coaxial tube has a first coaxial conduit and a second coaxial conduit inside, the first coaxial conduit is connected between the outlet of the condenser and the inlet of the battery box evaporator, and the second coaxial conduit is connected between the outlet of the battery box evaporator and the inlet of the compressor. In this way, thecoaxial tube is used as a regenerator such that the refrigerant in the cold plate is in a gas-liquid two-phase state to reach a consistent temperature of the cold plate, and at the same time, returnsto the suction portion of the compressor to become a superheat gas to protect the compressor. Therefore, the battery box direct cooling system is more reliable and has simple piping.
Description
technical field [0001] The present disclosure relates to the field of electric vehicles, and in particular, relates to a battery box direct cooling system, a control method thereof, a medium, and electronic equipment. Background technique [0002] The temperature in the battery box of an electric vehicle has a great influence on the reliability, life and performance of the battery cell. Therefore, it is particularly important to maintain the temperature in the battery box within a certain temperature range. This is mainly achieved through cooling and heating. The cooling methods of the battery box are divided into three types: air cooling, liquid cooling, and direct cooling. [0003] Air cooling uses low-temperature air as the medium and uses heat convection to reduce the temperature of the battery box. It is divided into natural cooling and forced cooling. Liquid cooling technology uses liquid convection heat exchange to take away the heat generated by the battery and redu...
