Description

Technical Field

[0001] This utility model relates to the technical field of battery cold plate testing equipment, and in particular to an adaptive liquid inlet / outlet device in a battery cold plate performance testing device. Background Technology

[0002] Battery cooling plates are key components in the thermal management system of new energy vehicle batteries. Their main function is to reduce the heat generated by the battery pack during operation through coolant circulation, ensuring the battery pack operates within a suitable temperature range, thereby improving battery performance and lifespan. Battery packs generate a significant amount of heat during operation; if this heat cannot be dissipated in time, it will lead to excessively high battery temperatures, affecting battery performance and lifespan. Therefore, the role of battery cooling plates in new energy vehicles is extremely important.

[0003] Combination Figure 1 The diagram shows the structure of a battery cooling plate 100. The battery cooling plate 100 includes a plate body 101 and a connector seat 102 located on the top surface of the plate body 101 near the right end. A coolant flow channel is provided inside the plate body 101. The inlet 102a on the connector seat 102 is connected to the inlet of the coolant flow channel, and the outlet 102b on the connector seat 102 is connected to the outlet of the coolant flow channel. Coolant enters the coolant flow channel inside the plate body 101 through the inlet 102a on the connector seat 102 and then flows out through the outlet 102b on the connector seat 102, thus forming a circulation. During this process, the coolant absorbs the heat generated by the battery pack.

[0004] The design and manufacturing of battery cold plates require consideration of various factors, among which flow resistance is one of the most important. Flow resistance refers to the pressure loss generated when the coolant flows through the coolant channels inside the battery cold plate under stable flow conditions; its value is equal to the static pressure difference between the inlet and outlet pipes.

[0005] In existing battery cold plate performance testing devices, a nozzle holder is fixedly installed on the workbench, and an inlet nozzle and a return nozzle are provided on the nozzle holder. When testing the battery cold plate 100, the battery cold plate 100 is placed on the sliding support plate of the performance testing device. The sliding support plate moves the battery cold plate 100 to a designated position. Simultaneously, the inlet nozzle and return nozzle on the nozzle holder are connected to the inlet 102a and outlet 102b of the battery cold plate 100. The above structure has the following problems:

[0006] (1) The battery cold plate follows the sliding tray to complete the docking process with the liquid inlet nozzle and the liquid return nozzle during the movement. Since the liquid inlet nozzle and the liquid return nozzle are fixed on the nozzle seat, and the nozzle seat is directly fixed on the worktable, the liquid inlet nozzle and the liquid return nozzle will impact each other when docking with the connector seat on the battery cold plate, which can easily cause damage to the liquid inlet nozzle and the liquid return nozzle, or damage to the connector seat.

[0007] (2) In the existing structure, since the inlet nozzle and return nozzle are fixed on the nozzle seat, and the nozzle seat is directly fixed on the worktable, the pitch angle and back-to-back sway angle of the inlet nozzle and return nozzle cannot be finely adjusted, which results in the inlet nozzle and return nozzle not being able to properly connect with the inlet and outlet of the battery cold plate. Utility Model Content

[0008] The main objective of this invention is to propose an adaptive liquid inlet / outlet device in a battery cold plate performance testing device, aiming to solve the aforementioned technical problems.

[0009] To achieve the above objectives, this utility model proposes an adaptive liquid inlet / outlet device in a battery cold plate performance testing apparatus, comprising a nozzle seat and a nozzle support; an inlet nozzle and a return nozzle are installed on the left end face of the nozzle seat; a vertical connecting plate is installed on the left side of the nozzle support, and a spherical bearing is installed in the center hole of the connecting plate; a universal joint is installed on the right end face of the nozzle seat, and the right end of the universal joint is slidably inserted into the inner ring of the spherical bearing; multiple buffers are installed on the connecting plate, and the buffer heads of the buffers are arranged to the left and abut against the nozzle seat; a first pipe connector and a second pipe connector are provided on the nozzle seat, and the first pipe connector is connected to the inlet nozzle, and the second pipe connector is connected to the return nozzle.

[0010] Preferably, the nozzle support includes a horizontal plate and a vertical plate; the vertical plate is welded to the left edge of the top surface of the horizontal plate, and a rib is welded between the vertical plate and the horizontal plate; a plurality of screw mounting holes are evenly distributed on the horizontal plate.

[0011] Preferably, the connecting plate is mounted on the vertical plate via multiple horizontal connecting rods; a connecting rod seat is mounted on the vertical plate; the left end of the horizontal connecting rod is connected to the connecting plate; and the right end of the horizontal connecting rod is inserted into the central hole of the connecting rod seat to form an interference fit.

[0012] Preferably, there are four horizontal connecting rods, and the left ends of the four horizontal connecting rods are respectively installed at the four corners of the connecting plate.

[0013] Preferably, a temperature sensor is provided on the nozzle seat, and the lower end of the temperature sensor extends into the connecting pipe between the second pipe joint and the return nozzle.

[0014] Preferably, a plurality of conical pits are provided on the right end face of the nozzle seat; the buffer head of the buffer abuts against the conical pits.

[0015] Preferably, the number of buffers is four, and they are evenly distributed in a ring around the central axis of the universal joint.

[0016] Preferably, the left end of the universal joint is integrally formed with a flange, and the flange is connected to the nozzle seat with screws.

[0017] Preferably, the first pipe connector is disposed on the rear end face of the nozzle seat, and the second pipe connector is disposed on the front end face of the nozzle seat.

[0018] Preferably, a sealing seat is inserted into the left end of the inlet nozzle and the return nozzle, and the sealing seat is made of rubber.

[0019] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0020] (1) In this utility model, since the right end of the universal joint is slidably inserted into the inner ring of the spherical bearing, and multiple buffers are installed on the connecting plate, and the buffer head of the buffer is set to the left and abuts against the nozzle seat, the nozzle seat forms a floating structure along the axial direction of the universal joint. Therefore, the impact force generated when the liquid inlet nozzle, liquid return nozzle and connector seat on the battery cold plate are connected can be reduced, effectively protecting the liquid inlet nozzle, liquid return nozzle and connector seat on the battery cold plate.

[0021] (2) In this utility model, since a universal joint is installed on the right end face of the nozzle seat and the right end of the universal joint is slidably inserted into the inner ring of the spherical bearing, the nozzle seat can swing slightly around the center of the spherical bearing, which is beneficial to ensure that the liquid inlet nozzle, the liquid return nozzle and the liquid inlet and liquid outlet of the battery cold plate are connected.

[0022] (3) By inserting sealing seats into the left ends of the liquid inlet and liquid return pipe respectively, and the sealing seats are made of rubber, when the liquid inlet and liquid outlet of the battery cold plate are connected to the liquid inlet and liquid return pipe respectively, the sealing seats will be compressed, thereby achieving the purpose of sealing.

The inlet 102a on the connector seat 102 is connected to the inlet of the coolant flow channel, and the outlet 102b on the connector seat 102 is connected to the outlet of the coolant flow channel. Coolant enters the coolant flow channel inside the plate body 101 through the inlet 102a on the connector seat 102 and then flows out through the outlet 102b on the connector seat 102, thus forming a circulation.
