Irregularly-shaped rotary heat pipe applicable to various rotation speeds

Abstract

The invention discloses an irregularly-shaped rotary heat pipe applicable to various rotation speeds. The heat pipe comprises a heat pipe main body, wherein the lower section of the heat pipe main body is a heat pipe evaporation section; the upper section of the heat pipe main body is a heat pipe cooling section; a condensate reflow structure is machined on the inner wall of the heat pipe; the lower end of the heat pipe evaporation section is provided with at least one branch layer; each branch layer is provided with at least two dendritic heat absorbing pipes; the heat absorbing pipes are uniformly distributed by taking the heat pipe main body as the center and extend towards the side lower part; the outer surfaces of the heat absorbing pipes are provided with ribs to form blades. Under the condition that the evaporation section of the heat pipe type stirring paddle is at a lower rotation speed, the gravity is used as main power for reflow of a working medium. Under the condition of higher rotation speed, centrifugal force produced by rotation is used as main power for reflow, so that the heat pipe type stirring paddle has excellent adaptability at various rotation speeds.

Description

technical field [0001] The invention relates to the field of heat pipe stirring bioreactors, in particular to a rotating heat pipe used for high temperature uniformity and high temperature control accuracy. Background technique [0002] Biological and chemical reactors usually need to export heat to control the temperature inside the reactor, and at the same time stir to make it mix well and the temperature is uniform. Therefore, general reactors are equipped with heat exchange jackets, and large reactors or large heat exchange capacity reactors also have built-in coil or straight tube heat exchange components, but these technologies have the problems of low heat exchange efficiency and large material consumption . And because the heat exchange equipment is static inside the equipment, the heat transfer effect is poor, and more heat exchange area is needed, which causes waste of reaction space, and also makes the temperature field of the reaction medium not uniform enough, ...

Problems solved by technology

Therefore, general reactors are equipped with heat exchange jackets, and large reactors or large heat exchange capacity reactors also have built-in coil or straight tube heat exchange components, but these technologies have the problems of low heat exchange efficiency and large material consumption

And because the heat exchange equipment is still inside the equipment, the heat transfer effect is poor, and more heat exchange area is required, which causes waste of reaction space, and also makes the temperature field of the reaction medium not uniform enough, making it difficult to accurately control the temperature

Invention patent "A Dynamic Heat Pipe Stirring Bioreactor for Multiple Biological Reactions" (CN 101182458) discloses a dynamic heat pipe stirring reactor for biological reactions, which solves the problem of enhanced heat transfer at low rotational speeds , but when the stirring shaft reaches a certain speed, the centrifugal force generated by the internal working medium due to the rotation makes the working fluid return operation line in the heat pipe uncertain, and there will be great defects in practical applications, especially when the rotating speed is high, the liquid There is basically no backflow, which will cause the heat pipe to fail. In addition, the cooling section of the heat pipe does not have a clear and feasible sealing structure, so that the water cooling method stays at the scheme stage
