Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a multifunctional integrated connector for new energy vehicles and a temperature adjustment method. Background Technology

[0002] In the current booming development of the new energy vehicle industry, high-voltage connectors, as key components for power transmission, directly affect the safety and reliability of the entire vehicle. Traditional electronic connectors, due to their fixed interface types and limited functionality, are gradually failing to meet the demands. For example, existing connectors typically only support a single standard interface (high-power or low-power interface). When devices require compatible interfaces, multiple independent connectors must be spliced ​​together, resulting in bulky size, cumbersome installation, and significant signal interference issues between different interfaces.

[0003] Furthermore, with the continuous increase in automotive power density, the heat generated by high-voltage connectors under high current and high voltage conditions increases dramatically, easily leading to problems such as terminal oxidation and insulation material aging. This, in turn, results in increased contact resistance, decreased transmission efficiency, and even fire hazards. Traditional heat dissipation methods, such as natural heat dissipation and simple air cooling, are no longer sufficient to meet the thermal management requirements of high-voltage connectors due to their low heat dissipation efficiency. Existing liquid cooling solutions generally suffer from problems such as unreasonable flow channel design and poor heat dissipation uniformity, making it difficult to achieve precise temperature control and leading to frequent localized overheating.

The opening of the first valve is controlled based on the temperature difference between the temperature data from the first temperature sensor and the ambient temperature, and the first target opening calculated by the temperature control PID. The opening of the second valve is controlled based on the temperature difference between the temperature data from the second temperature sensor and the ambient temperature, and the second target opening calculated by the temperature control PID.

8. The method according to claim 7, characterized in that, It also includes the following steps: During the adjustment of the opening degrees of the first valve, the second valve, and the third valve, if any of the above-mentioned actions are taken... The target flow rate Q corresponding to the valve opening obtained by formula calculation 目 The actual flow rate Q is collected in real time by the flow sensor of the corresponding cooling channel. 实 satisfy: Then, adjust the valve opening of the corresponding cooling channel as follows: , ; or , ； in, The valve opening is calculated using any of the above formulas. For the adjusted phase The valve opening of the cooling channel should be adjusted.

9. An electronic device, characterized in that, Includes a processor and a memory, wherein the memory... The processor is used to store a computer program, the computer program including program instructions, and the processor is configured to invoke the program instructions to perform the method as described in any one of claims 5-8.

10. A computer-readable storage medium, characterized in that, The computer-readable storage medium stores The computer program contains program instructions that, when executed by a processor, cause the processor to perform the method as described in any one of claims 5-8.
