Solid-liquid mixed baffle plate type internal heat exchanger for space radiator

Abstract

The invention discloses a solid-liquid two-phase flow mixed spiral baffle plate type internal heat exchanger in space environment based on the principles of enhanced convection heat transfer and thermal radiation, comprising the following five parts: (1) a heat source accessing pipe, (2) a cold source accessing pipe, (3) a mixing heat exchange tube, (4) a tube baffle plate, and (5) fins outside the mixing heat exchange tube. Because the traditional internal heat exchanger has the disadvantages of low heat conductivity, easy generation of deposition and large energy consumption, and can not work long hours, the invention, based on overcoming the disadvantages, combines a mixing heat exchange technology, a particle enhanced convection heat transfer technology, a field coordinated convectiveenhanced heat transfer technology, and a thermal radiation technology, effectively reduces the mass and the occupied volume of the internal heat exchanger, simultaneously increases the heat exchange efficiency, reduces the loss in the heat transfer, reduces production cost, eliminates the deposition, increases the vibration resistance and operation stability, and expands the application scope.

Description

technical field [0001] The invention relates to a solid-liquid two-phase flow mixed spiral baffle type intermediate heat exchanger based on the principle of enhanced convection heat transfer and the principle of radiation heat dissipation, which is applied in a space environment. It is used to efficiently mix and exchange heat between the liquid working flow that absorbs the waste heat generated inside the spacecraft and the solid particle flow that has been cooled by radiation heat exchange. Background technique [0002] A heat exchanger, also called a heat exchanger, is a device that transfers heat from one medium to another. According to the way of heat transfer in the heat exchanger, the heat exchanger can be divided into four categories: direct contact heat exchanger, periodic flow heat exchanger, partition wall heat exchanger and fluid coupling indirect heat exchanger. [0003] Direct contact heat exchangers, also known as hybrid heat exchangers, are equipment in whic...
