Controllable bi-circulating hot-pipe system

Abstract

This invention relates to a double- cycle high efficient heat pipe heat exchanging system that can control the heat exchanging quantity. There are evaporator and condenser two types of heat exchangers. The number of each type is one or several that formed by connected in parallel. This system includes: condensate supplying and distributing system; gas-liquid two phases flowing and separating system; gaseous phase transmitting and distributing system, liquid phase collecting and storing system; heat exchanging quantity controlling system. The evaporator of heat pipe, condenser, gas-liquid separator, liquid storage, solution circulating pump, liquid distributor, the connecting pipeline and related controlling parts are connected together to form the double cycles controllable heat pipe system. The solution pump, liquid distributor, evaporator and gas-liquid separator are connected together to form independent working fluid cycle, which settle the problems that working fluid carrying capacity is not enough and liquid distribution is uneven.

Description

Technical field: [0001] The invention relates to the technical field of heat pipe heat exchangers, in particular to a high-efficiency heat pipe heat exchange device with double-cycle controllable heat exchange, that is, a double-cycle controllable heat pipe system. technical background: [0002] As early as 1942, Gauler proposed the principle of heat pipes, but it has not been implemented; since Cotter first proposed a relatively complete theory of heat management in 1965, scientists from various countries have carried out theoretical research and popularization of heat pipes. As a component with high heat transfer performance, heat pipe is widely used in many fields and has achieved very good energy saving effect. In 1985, Shi Guoliang proposed the concept of "second-generation heat pipe" and applied for a national invention patent (patent number: CN 85102929). However, due to the design of the electric pump inside the heat pipe, there are great difficulties in implementat...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems of insufficient working fluid delivery force, uneven liquid separation, use effect far inferior to the one-piece heat pipe and no control function of the separate heat pipe, that is, to propose a new "heat pipe system". The evaporation section and condensation section of the original "heat pipe element" are organically connected with several other necessary components to form an independent system to overcome the shortcomings of separate heat pipes

The heat pipe system forms a relatively independent working liquid cycle (small cycle in the double cycle) through the organic combination of the solution circulation pump, liquid separator, evaporator and gas-liquid separator, which solves the problem of insufficient working liquid delivery and liquid separation. The problem of unevenness; and through the control of the circulation flow, the control of the heat transfer amount of the heat pipe is realized
