Description

Technical Field

[0001] The utility model relates to the technical field of battery liquid cooling devices, in particular to a battery bracket with a large-area liquid cooling plate integrated on the bottom surface for engineering machinery. Background Art

[0002] With the development of new energy technologies, more and more battery thermal management systems use liquid cooling instead of air cooling, and the technology related to liquid cooling pipelines in battery systems has attracted the attention of more and more battery and vehicle manufacturers.

[0003] In the prior art, the traditional liquid cooling solution for engineering machinery uses liquid cooling pipes that are attached to the battery box or pass through the battery box. Condensed water circulates through the liquid cooling pipes, takes out heat to the area outside the battery for cooling, and then circulates back to the area near the battery to continue to take away the heat from the battery.

[0004] However, the liquid cooling solution in the prior art still has certain shortcomings during use:

[0005] 1. The battery bracket added to meet the vibration resistance and stability requirements of the power battery and the liquid cooling pipeline designed to meet the thermal management and heat dissipation requirements of the power battery often interfere with each other during assembly, which can easily affect each other's application performance.

[0006] 2. The vehicle cost of the model in which the battery bracket and liquid cooling pipes are separated is higher than that of the model in which the battery bracket and liquid cooling pipes are integrated together.

[0007] 3. The solution of directly inserting the liquid cooling tube into the battery pack has the problem of high battery system cost. When the battery pack is hit, the liquid cooling tube is easily squeezed and ruptured, and the coolant may come into contact with the battery cell. The safety and stability need to be further improved. Utility Model Content

[0008] The purpose of the utility model is to solve the problems raised in the above-mentioned background technology, and to propose a battery bracket for engineering machinery with a large-area liquid cooling plate integrated on the bottom surface.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A battery bracket for engineering machinery with a bottom surface integrated with a large-area liquid cooling plate, comprising:

[0011] The bracket body gives way;

[0012] The mounting plate is fixedly connected to the bracket body's recess;

[0013] The liquid cooling plate recess is fixedly connected to the bottom of the recess of the bracket body;

[0014] The liquid cooling plate recess and the mounting plate recess are in contact with each other;

[0015] The liquid cooling plate concession grooves are provided in a plurality of groups, and the plurality of groups of liquid cooling plate concession grooves are symmetrically arranged on the bracket body concession grooves.

[0016] Preferably, a water inlet pipe concession groove is fixedly connected to the liquid cooling plate concession groove.

[0017] Furthermore, a water outlet pipe giving way groove is fixedly connected to the liquid cooling plate giving way groove, and the water outlet pipe giving way groove is located below the water inlet pipe giving way groove.

[0018] Furthermore, the liquid cooling plate giving way grooves are fixedly connected with connecting pipe giving way grooves, and two adjacent groups of the liquid cooling plate giving way grooves are connected via the connecting pipe giving way grooves.

[0019] Furthermore, a make way groove is provided on the bracket body.

[0020] Furthermore, the give way groove is an elliptical groove.

[0021] Preferably, a first mounting hole give-away groove is provided on the bracket body give-away groove, and a second mounting hole give-away groove is provided on the liquid cooling plate give-away groove, and the first mounting hole give-away groove matches the second mounting hole give-away groove.

[0022] Furthermore, the first mounting hole clearance groove and the second mounting hole clearance groove are threaded holes.

[0023] Compared with the prior art, the utility model provides a battery bracket for engineering machinery with a large-area liquid cooling plate integrated on the bottom surface, which has the following beneficial effects:

[0024] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model uses the liquid cooling plate give way groove in the device to cool the battery body installed in the give way groove of the bracket body, and there is no need to install a large number of liquid cooling pipelines, which simplifies the production and assembly and improves the production efficiency; at the same time, the space of each layer of the give way groove of the bracket body can be further reduced, thereby improving the overall energy density of the battery box.

[0025] By using the liquid cooling plate give way groove in the device to cool the battery body installed in the bracket body give way groove, when the bracket body give way groove is impacted, the battery body will not be affected by the rupture of the pipeline, thereby reducing the possibility of coolant contacting the bracket and the battery cell, and improving the stability and safety of the battery body.
