Temperature control valve based on corrugated pipe structure

Abstract

The invention provides a temperature control valve based on a corrugated pipe structure and belongs to the technical field of heat control. The temperature control valve comprises a corrugated pipe, alinear stepper motor and a sliding valve. One end of the corrugated pipe is connected with the linear stepper motor, and the other end of the corrugated pipe is connected with the sliding valve. Under the condition that the size of the temperature control valve is fixed, moving and dynamic sealing of a motor rod and the sliding valve can be guaranteed, the linear stepper motor converts rotation of a rotor under an electromagnetic field into linear motion of the motor rod, and the sliding valve can guarantee that full opening and closing of two outlets of the temperature control valve are achieved, so that the requirement for flow changing at the different flow speeds is met. The temperature control valve is applied to a spacecraft, is simple in structure, and meets various different temperature control requirements on the spacecraft.

Description

technical field [0001] The invention relates to the technical field of thermal control, and is particularly suitable for single-phase fluid circuits and two-phase fluid circuits that adopt different temperature control strategies for changes in the sun-receiving surface. Background technique [0002] The requirements of spacecraft for thermal control systems show a trend of diversification with the characteristics of their respective missions and the complex changes of the space thermal environment, and put forward higher requirements in terms of accuracy, reliability, robustness and sensitivity. As an important method in the active thermal control technology of spacecraft, the fluid circuit system uses a mechanical pump to drive liquid forced convection circulation to control heat. Because of its strong heat transfer capacity, convenient structure layout, easy organization of internal heat transfer, safety and reliability, it has been widely used in many spacecraft at home ...

AI Technical Summary

Problems solved by technology

NASA applied the paraffin-type temperature control valve to the two-phase loop heat pipe of the lunar rover, and the hysteresis of the paraffin itself caused the oscillation of the system temperature to not be fundamentally resolved

Conventional passive temperature control valves are difficult to adapt to the complex space thermal environment, and the flexibility and maneuverability are difficult to meet the requirements, especially in the face of problems such as heat dissipation of satellite high-power consumption platforms, and local stand-alone temperature is too high

Active temperature control valves are mainly motor-driven temperature control valves, which currently have the disadvantages of complex structure and bulky volume
