Description

Technical Field

[0001] The utility model belongs to the technical field of liquid cooling temperature control, and in particular relates to a liquid cooling mechanism for power exchange equipment. Background Art

[0002] In current battery swapping equipment, batteries generate a large amount of heat during the charging process; therefore, heat exchange equipment is needed to ensure the operation of the equipment, the safety and service life of the battery pack. In the field of heat exchange, compared with traditional air cooling technology, liquid cooling technology utilizes the high thermal conductivity of liquid to quickly conduct heat away from the heat source, making it have a higher energy efficiency ratio and lower energy consumption. Therefore, the application of this technology in battery swapping equipment is extremely cost-effective.

[0003] A conventional liquid cooling mechanism usually includes a water tank, a water inlet pipe and a water outlet pipe connected to the water tank, and a water pump for providing pumping power is connected to the water outlet pipe; a conventional liquid cooling mechanism can meet the needs of conventional use environments, but in large-scale battery exchange equipment, the battery generates a lot of heat, so the required heat exchange frequency will increase, which requires the water pump to further accelerate its operation, and the accelerated operation of the water pump causes the vibration frequency of the water outlet pipe to increase. Over time, it is easy to cause the connection between the water outlet pipe and the water tank, or the water outlet pipe and the water pump to break. In addition, during the connection and installation process of the water outlet pipe, water pump, and water tank, due to the influence of the installation site, etc., it is often impossible to accurately align them. At this time, the connection of each group may be achieved by raising a certain part. At this time, although the installation of each group can be guaranteed, in the face of the high-frequency vibration generated by the water pump, the workpiece used for raising may be offset or even detached, which will also make it easier for the connection between the water pipe and the water tank or the water pipe and the water pump to break. Therefore, a design solution is needed to solve the above problems. Utility Model Content

[0015] Beneficial effects of the utility model: the utility model connects a connecting hose between the liquid outlet pipe and the water tank, so that the connecting hose can bear certain displacement and deformation during the operation of the equipment, which can not only ensure the convenience of the installation process, but also avoid the connection between the liquid outlet pipe and the water tank, or the liquid outlet pipe and the water pump from being broken due to the high-frequency vibration of the water pump, thereby effectively improving the service life of the equipment;

[0016] Among them, by limiting the length of the connecting hose, high-frequency vibration caused by the low strength of the connecting hose can be reduced.
