Self-adaptive temperature control system

Abstract

The invention provides a self-adaptive temperature control system. The self-adaptive temperature control system comprises a spraying module, a phase change material and a self-adaptive valve body, wherein the spraying module is provided with a liquid discharging assembly and is used for spraying a fluid working medium onto the surface of heat generating equipment; the phase change material is arranged in the circumferential direction of the heat generating equipment and controls the temperature of the heat generating equipment before being completely thawed; the self-adaptive valve body is arranged on the liquid discharging assembly and is used for opening or closing the liquid discharging assembly so as to achieve temperature control of the heat generating equipment after the phase changematerial is completely thawed. When the heat generating equipment has low power, the temperature is controlled through the phase change material; when the heat generating equipment has high power, the phase change material is completely thawed, the temperature continuously rises, and the temperature is controlled through combination of the self-adaptive valve body and the spraying module; the self-adaptive temperature control of the heat generating equipment is achieved, the heat exchanging process is self-adaptive, and temperature measurement and calculation of a temperature control processor are not required.

Description

technical field [0001] The present invention proposes an adaptive temperature control system, which is suitable for adaptive temperature control of heating equipment of unmanned aerial vehicles. Background technique [0002] The performance and functions of UAVs have increased, and the heating power of airborne heating equipment varies greatly in different flight stages due to different working modes, and more stringent requirements are put forward for the adaptive temperature control requirements of heating equipment. [0003] At present, there are two ways to control the temperature of heating equipment on board drones: passive control and active temperature control. Passive temperature control of phase change materials and passive temperature control relying on structural equipment are relatively common temperature control methods. The method of passive temperature control relying on structural design has no self-adaptive ability, and for equipment with large changes in h...

Problems solved by technology

In this process, the precise measurement of the temperature sensor and the reliable operation of the temperature control processor and the flow control valve are required as preconditions. If any link fails, the entire system will fail, which is not good for the temperature control of the drone’s onboard heating equipment.

In addition, the use of ram air heat exchange and single-phase liquid cooling circuit heat exchange has limited heat exchange capacity, which is only effective for temperature control of heating equipment with low power heat flux density, and for instantaneous high power pulse or continuous high heat flux heat generation As far as the equipment is concerned, it is impossible to quickly cool down the heating equipment of the drone, and it is easy to cause the temperature of the equipment to overheat.

[0005] In summary, the conventional passive thermal control and active thermal control schemes have many disadvantages for the temperature control of UAV heating equipment with complex performance, high system integration and frequent changes in working modes.
