Description

Technical Field

[0001] This utility model relates to the technical field of liquid-cooled plate testing equipment, specifically a liquid-cooled plate testing fixture. Background Technology

[0002] The liquid cooling plate for electric vehicles is a cooling device for the battery system of electric vehicles. Existing liquid cooling plates typically use extruded flat tubes made of aluminum. The extruded flat tube has two water nozzles, and the cavity of the extruded flat tube is connected to the two water nozzles respectively. Coolant is injected into the cavity of the extruded flat tube from one water nozzle and then flows out from the other water nozzle, thus forming a coolant circulation cooling device. Since the coolant needs to flow continuously in the cavity of the electric vehicle liquid cooling plate, the sealing performance of the electric vehicle liquid cooling plate is required to be high. Otherwise, coolant leakage may easily occur and damage the battery. However, the current liquid cooling plate testing fixtures have the following problems: they are not convenient for rapid positioning and testing. Traditional liquid cooling plate testing fixtures are not convenient for rapid testing. Utility Model Content

[0008] Specifically, the front end of the limiting connecting plate is provided with a support plate, and the front end of the support plate is provided with a guide roller.

[0009] Specifically, the connecting pipe is threadedly connected to the liquid cooling plate via a docking screw head, and the air pump introduces gas into the liquid cooling plate through the connecting pipe and the docking screw head.

Gas is introduced through the air pump 6 and the connecting pipe 7 to conduct a pressure test, and the data is acquired through the pressure gauge 8. The liquid cooling plate 4 is guided to the guide roller 11, and then, under the guidance of the guide roller 11, the liquid cooling plate 4 reaches the support plate 12. At this time, the push frame 13 provides bottom support and limitation. Then, the user threadedly connects the docking screw head 9 to the liquid cooling plate 4.

Gas can also be introduced from the other side to make the gas in the liquid cooling plate 4 reach the standard pressure value. After 10 minutes, data is acquired to check whether the internal pressure value has decreased. This is visually detected by the pressure gauge 8. Then, the liquid cooling plate 4 and the docking screw head 9 are separated. The limit connecting plate 14 is extended by the electro-hydraulic push rod 15, which pushes the liquid cooling plate 4 to move. The liquid cooling plate 4 is then guided by the guide roller 11 for continuous testing.

[0026] Working principle: During production, the liquid cooling plate 4 is guided onto the guide roller 11. Then, guided by the guide roller 11, the liquid cooling plate 4 reaches the support plate 12. At this time, the push frame 13 provides bottom support and limit. Then, the user connects the docking screw head 9 to the liquid cooling plate 4 by thread. Gas is introduced through the air pump 6. The gas is guided into the liquid cooling plate 4 through the connecting pipe 7 and the docking screw head 9. Gas can also be introduced from the other side, so that the gas in the liquid cooling plate 4 reaches the standard pressure value.
