Abstract

The invention discloses double-pump heat pipe type heat exchange equipment, which mainly comprises a condenser (1), a condenser circulating pump (2), a liquid storage tank (3), an evaporator circulating pump (4), an evaporator (5) and a circuit control part, wherein the condenser (1) and the condenser circulating pump (2) form a circulating loop, the evaporator (5) and the evaporator circulating pump (4) form a circulating loop, and the liquid storage tank (3) is arranged at the fusion point of the two loops, so that a whole double-pump heat pipe type heat exchange loop is formed, more energy conservation and higher efficiency are realized on the basis of the original heat pipe principle, and the problem that gas and liquid in the original heat pipe cannot be obviously separated is solved.

Description

A kind of double pump heat pipe-type heat transmission equipment

Technical field

The present invention relates to the heat exchange field, definite a kind of heat pipe heat exchanger unit of saying so relates in particular to a kind of double pump heat pipe-type heat transmission equipment.

Background technology

In current society; The air-conditioning heat transfer technology is well developed; Burn the wind especially at the heat pump air conditioner technical elements, the air-conditioning that generally uses as present family, refrigerator etc. all utilize the heat pump heat transfer technology, though the heat pump heat transfer technology is quite ripe; But with respect to the heat pipe heat exchanging technology; The heat pump heat transfer technology is not the most energy-conservation, and the heat pump heat transfer technology must rely on the workmanship of compressor to realize the running of whole system, and most basic heat pipe heat exchanging technology is to rely on the character of thermal medium self to operate fully.Heat pipe one end is evaporation ends (being generally the heat pipe bottom), and other one section is condensation end (being generally heat pipe top), when heat pipe one end is heated; Condensing agent liquid in pipe evaporation rapidly becomes steam, and steam flows to an other end under the effect of gas self property, and discharges heat; Regelation becomes liquid; Condensing agent liquid flows back to evaporation ends under the effect by the liquid self gravitation again, and so circulation is more than, and heat reaches an other end by heat pipe one end.This circulation is carried out fast, and heat can be conducted come evaporation, condensation, the final purpose that realizes just can reaching without the effect of external work heat exchange continuously.

But present hot pipe technique is not very ripe; In the thicker heat pipe of diameter, the stall limit of gas, liquid clearly, so that the gas-liquid of condensing agent goes up and down to carry out is more smooth; And constantly reducing along with the heat pipe caliber; The gas-liquid mixed phenomenon of heat transferring medium is more and more heavier in the heat pipe, and the condensing agent that becomes gaseous state after the heat absorption can't rise at once, and the condensing agent liquid in the heat pipe condensation end can't be gone into evaporation ends because of the gravity effect free-falling rapidly of self; But be detained a part of liquid condensation agent at condensation end; When the liquid condensation agent ran up to a certain degree, it just can get into evaporation ends because of the seldom a part of liquid condensation agent in reason whereabouts of pressure, thereby the gas-liquid mixed phenomenon occurred; This phenomenon also just makes the gaseous state of condensing agent in the heat pipe or liquid state well not move around; This has also just limited the heat exchange efficiency of heat pipe heat exchanging technology, though heat pipe heat exchanging can not obtain excellent popularization than the more energy-conservation more environmental protection of heat pump heat exchange in the practical application in theory.

Summary of the invention

Because in the heat pipe of slim pipe diameter; The gas-liquid mixed phenomenon that occurs can not get solving; Thereby limited the popularization of heat pipe; For this problem, the improvement of the present invention through the opposite heat tube device fundamentally solved gas-liquid mixed and the problem that causes the action and efficacy of heat-pipe apparatus not improve.

Added in this invention and can control two Gas-liquid pumps that condensing agent circulates, the circulation power in the system is resolved; And in fluid reservoir, install gas-liquid separation equipment, what gas-liquid can maximum possible when realizing heat exchange separates, thereby working environment efficiently is provided; This equipment can controlled the logic operation and the connecting and disconnecting of the circuit of entire equipment through the circuit control section aspect control, realizes the automatic operating of equipment.

Description of drawings

Fig. 1 is the simple structure sketch map of double pump heat pipe-type heat transmission equipment;

(1) condenser; (2) condenser circulating pump; (3) fluid reservoir; (4) evaporimeter circulating pump; (5) evaporimeter.

A kind of double pump heat pipe-type heat transmission equipment mainly is made up of condenser (1), condenser circulating pump (2), fluid reservoir (3), evaporimeter circulating pump (4), evaporimeter (5) and circuit control section; Said condenser (1) and condenser circulating pump (2) are formed a closed circuit, and the air inlet pipe of condenser (1) inserts in the fluid reservoir (3), and drain pipe also gets into fluid reservoir (3) after connecting condenser circulating pump (2); Said evaporimeter (5) and evaporimeter circulating pump (4) are formed a closed circuit, and the feed liquor mouth of pipe of evaporimeter (5) connects evaporimeter circulating pump (4) back and inserts fluid reservoir (3), and the mouth of pipe of giving vent to anger also inserts in the fluid reservoir (3); The merging point in two loops is fluid reservoir (3), has so just formed whole double pump heat pipe-type heat-exchanging loop system.

When condenser (1) is emitted heat in environment; Gaseous state condensing agent liquefy; And the power that liquid condensing agent provides through condenser circulating pump (2); The liquid condensation agent flows in the fluid reservoir (3); Certainly having comprised sub-fraction in these liquid condensation agent does not also have the gaseous state condensing agent of total condensation yet, after the liquid condensation agent that contains a small amount of gaseous state condensing agent gets into fluid reservoir (3), through the interior gas-liquid separation device of fluid reservoir (3) the gaseous state condensing agent is separated from liquid; And these a spot of gaseous state condensing agents are from the inlet entering of condenser (1); Carry out cool cycles once more, the power that the liquid condensation agent after the separation provides through evaporimeter circulating pump (4) gets in the evaporimeter (5) from fluid reservoir (3) and carries out endothermic gasification, and the condensing agent after the gasification is being mingled with a spot of liquid condensation agent and is getting in the fluid reservoir (3); Through after the gas-liquid separation; The gaseous state condensing agent of separating gets into and gets into next circulation in the condenser (1), and the liquid condensation agent of gasification has not so just solved the drawback that is difficult to circulate when the conventional heat pipe gas-liquid is not separated again through evaporating in evaporimeter circulating pump (4) the back entering evaporimeter (5).Said circuit control section is being controlled the unlatching operation of condenser circulating pump (2) and evaporimeter circulating pump (4), has so just constituted the operation of whole double pump heat pipe-type heat transmission equipment.
