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 sho

Example Embodiment

[0033] Embodiment 1: The structure and work flow of the first embodiment of the present invention. Its main components include an evaporator 7 and a condenser 2; it also includes a solution circulation pump 18, a liquid transport pipe 15, a liquid distributor 16, etc. Condensate liquid supply and distribution subsystem composed of a length of distribution tube bundle 8 and so on; gas-liquid two-phase flow and separation subsystem composed of two-phase flow conveying tube bundle 6 and gas-liquid separator 14; gas-phase working fluid passes through conveying pipe 5 , The gas phase conveying and distribution subsystem consisting of the gas phase working fluid main pipe 4 and the uniform gas distribution pipe 3; consisting of the pressure regulating valve 13, the gas-liquid separator liquid conveying pipe 12, the condenser condensate conveying pipe 10 and the liquid storage tank 11 Liquid phase collection and storage subsystem; a heat exchange control subsystem composed of a temperatu...

Example Embodiment

[0035] Embodiment 2: The structure and work flow of the second embodiment of the present invention. Its evaporator 7 and condenser 2 and condensate supply and distribution, gas-liquid two-phase flow and separation, gas-phase transportation and distribution, and liquid-phase collection The storage of the four sub-systems is exactly the same as in Embodiment 1, but the heat exchange control sub-system is different. Embodiment 1 uses a temperature controller 17 to control the rotation speed of the solution circulating pump to adjust the flow of the liquid working fluid. In this embodiment, a temperature regulating valve 19 is installed on the circulating solution delivery pipe 15. The temperature signal transmission tube 9 directly adjusts the flow rate.

[0036] The startup and operation process of this embodiment is the same as that of the first embodiment.

Example Embodiment

[0037] Embodiment 3: The structure and work flow of the third embodiment of the present invention. Its evaporator 7 and condenser 2 and condensate supply and distribution, gas-liquid two-phase flow and separation, gas-phase transportation and distribution, and heat exchange The control of the four subsystems is exactly the same as in Example 1, but the liquid phase collection and storage are different. In the embodiment 1, the condensate of the condenser 2 directly flows into the liquid storage tank 11 by gravity, so the installation height of the liquid storage must be lower than the lowest point of the condenser, and this embodiment uses the condensate return pipe 10 The installation of a solution pump 20 on the top allows the installation height of the condenser 2 to be lower than that of the accumulator 11, which makes the installation and arrangement of the condenser more flexible.

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...
