Description

Technical Field

[0001] This utility model relates to the field of electrical connections, and in particular to a power swapping connector with a phase change heat dissipation structure. Background Technology

[0002] With the development of new energy vehicles, electric vehicles are becoming increasingly widely used. Battery swapping connectors are used to connect battery packs to the vehicle, enabling charging and discharging. Currently, most battery swapping connectors used in charging stations on the market use high-current charging and short-time charging and discharging. The drawbacks are: firstly, a large amount of heat is generated during charging and discharging, which accumulates in the battery swapping connector and cannot be dissipated, easily leading to overheating and potential connector burn-out, posing a safety hazard; secondly, current heat dissipation methods, such as traditional air cooling or adding heat sinks, have poor heat dissipation effects and cannot effectively dissipate excessive instantaneous heat, thus failing to cool the entire battery swapping connector and affecting the product's lifespan.

The rear end of the insertion part is inserted into the heat dissipation shaft hole and the two ends of the heat dissipation shaft hole are sealed by the sealing part. The internal gap between the two forms a heat dissipation cavity.

[0009] In some implementations, two adjacent heat dissipation shaft holes are connected by a transverse connecting hole, so that the temperature of the two heat dissipation chambers changes uniformly.

[0010] In some embodiments, there are two sockets, terminals, and wires; the rear ends of the two heat dissipation pipes of the heat dissipation shell are integrally and symmetrically connected to the two shaft holes of the front end block and the rear end pipe hole of the front end sleeve inner shell, the pipe hole of the heat dissipation pipe is a heat dissipation shaft hole, and the transverse connecting hole is set between the two shaft holes of the front end block.

[0011] In some embodiments, the front end block is provided with at least two heat dissipation blind holes, one end of which is connected to the circumferential wall of the heat dissipation shaft hole and the other end extends to the rear side wall of the front end block.

[0012] In some implementations, large-diameter end-positioning grooves are provided at the front and rear ends of the heat dissipation shaft hole;

[0013] The rear end of the insertion part is provided with two positioning retaining rings. The positioning retaining rings are connected to the positioning groove with a gap and are connected to the positioning groove by an interference seal through a sealing element.

[0034] The phase change heat dissipation module 01 of this battery swapping connector with a phase change heat dissipation structure is equipped with a phase change material 011. The phase change material 011 can rapidly release and absorb heat through a phase change, exhibiting highly efficient heat dissipation capabilities. The phase change heat dissipation module 01 is located near the heat source (the connection between terminal 4 and the socket 3) and absorbs a large amount of heat instantaneously through the phase change of the phase change material 011, keeping the connector operating at a safe temperature. Furthermore, after a short charging period, when no additional heat is generated, it quickly releases heat to return to its original state for repeated use. Its beneficial effects are: firstly, in special operating conditions or environments with large temperature variations, the phase change material... The heat dissipation module 01 can effectively and quickly absorb and release heat, avoiding the problem of excessive instantaneous heat dissipation. The battery swapping connector can operate safely and stably without overheating, thus having a high heat dissipation capacity. It is suitable for a variety of complex and abnormal working conditions, allowing the battery swapping connector to play its full role. Secondly, it improves the thermal management capability of the connector, effectively avoiding overheating, burning and other phenomena, and ensuring high safety. Thirdly, the phase change heat dissipation module 01 uses material phase change to absorb and release heat, with good heat dissipation effect. It is suitable for dissipating excessive instantaneous heat, effectively cooling the entire battery swapping connector, improving the product's charging efficiency, reliability and service life.

[0035] Furthermore, the phase change heat dissipation module 01 includes a heat dissipation shell 2, which is fixedly connected to the rear end of the inner shell 10 of the shell assembly 1. The heat dissipation shell 2 is provided with multiple parallel heat dissipation shaft holes 200. The rear end of the insertion member 3 is inserted into the heat dissipation shaft holes 200 and the two ends of the heat dissipation shaft holes 200 are sealed by the sealing member 012. The internal gap between the two forms a heat dissipation cavity 010. Its beneficial effect is that this arrangement can form a well-sealed heat dissipation cavity 010, and the phase change material can effectively cover the high heat area, resulting in a highly efficient heat dissipation effect.

[0036] Preferably, two adjacent heat dissipation shaft holes 200 are connected by a transverse connecting hole 201, so that the temperature of the two heat dissipation cavities 010 changes uniformly.

[0037] Furthermore, when there are two of each of the socket 3, terminal 4, and wire 5, the heat sink 2 includes two parallel heat sink pipes 20 and a transverse front end block 21. The rear ends of the two heat sink pipes 20 are integrally and symmetrically connected to the two shaft holes of the front end block 21, and the front ends are inserted into the rear end pipe hole 100 of the inner shell 10.

Its advantages are: this arrangement has a good positioning effect and ensures good installation sealing performance.

The beneficial effect is that this arrangement facilitates uniform heat dissipation and prevents local heat accumulation.

[0042] Preferably, the front end face of the front end block 21 is integrally fitted to the rear wall of the inner shell 10. The front end block 21 is provided with several stepped through holes 22. Countersunk screws or cylindrical head screws pass through the stepped through holes 22 and are threaded to the rear wall of the inner shell 10. Its advantages are: this setting is easy to install and has a small size.

[0043] The front end block 21 also has an integrally formed annular sealing shell 23 at its rear end.

The rear ends of the two terminals 4 are ultrasonically welded with positive and negative wires 5, and their front ends pass through the sealing wire body 014 into the annular sealing shell 23 and are coupled to the insertion hole 3 at the end. Its beneficial effect is that this setting allows the heat dissipation shell 2 to integrate the function of the rear mounting plate, and the overall structure is compact.
