Abstract

The utility model provides a heat pipe pump for a new power machine heat transferring device and the inner end of a heat pipe is arranged in a power machine to be closely jointed with the power heat sensing element of the heat pipe pump. The outer end of the heat pipe extends out of the shell of the power machine to become the fixer or rotor of the heat pipe pump and the fixer or rotor is coaxially arranged and synchronously works with the power machine. Through the heat pipe, the heat of the power machine is taken out to be transferred to the working media of the heat pipe pump and the normal work of the power machine is ensured. The heat pipe pump has the double functions of a close-packed heat exchanger and a pump and provides a heat exchanging channel with the outer world for the main power machine. The heat pipe pump is the ideal accessory equipment of the industrialization practicality of new power machines such as the rare earth permanent magnet power machine, the superconducting motor, etc.

Description

Hot-tube pump, a new power machine heat transmission device

The utility model relates to a kind of heat transfer unit (HTU)-heat pipe pump of new power machine, belongs to the attached corollary equipment of this engine.

The exceptional function of the magnetoelectricity alternating action that rare-earth permanent magnet motor or generator had, the application on energy conversion have exceeded the original expectation of people, and its application prospect is very considerable.But people have also been adjourned some technical more reluctant thorny problems in actual applications.The heat exchange of rare-earth magnet is exactly one of them.We know that rare-earth magnet can produce a large amount of heat energy in the course of the work inevitably.For the machine maintenance operate as normal, should set up the timely and extraneous exchange of heat energy that heat transfer path produces magnet.The machine that turns round under certain duty just must solve corresponding to the quantitative exchange heat of this state.Otherwise, the temperature at the thermo-responsive position of engine will raise, and the magnetic property of rare-earth magnet keeps certain relation with temperature, has reached the critical value of safeguarding its condition of work if the magnetic property that the variation that temperature raises causes changes, and machine certainly will can not be safeguarded its normal duty.Produced the permanent magnetic power machine model of principle formula and can run well the reason of in the time will making the rare earth permanent magnet engine that to export certain power, just collapsing after a single setback though this also is the utility model people who has.

Order of the present utility model is exactly a kind of heat transfer unit (HTU)--the heat pipe pump that provides for the heat transfer problem that solves rare earth permanent magnet engine or other new type power machines.

The utility model is and main frame--new power machine--matching used a kind of auxiliary device, with the coaxial installation of engine, the heat pipe pump that works asynchronously.It is made up of plural a plurality of heat pipes, wherein the inner of each heat pipe all fits tightly with the back side that is contained in each magnetic pole unit (or other power heat-sensitive elements) on the engine, and the outer end of heat pipe is then drawn the shell of engine and extend into the interior fin that forms heat pipe pump of housing of heat pipe pump.From the heat pipe fin that the power machine stator is drawn, in the pump housing, become the stator or the stator of pump.From the heat pipe fin that the power machine rotor is drawn, in the pump housing, become the rotor or the impeller of pump.

The utility model is to be heat transfer path with the heat pipe, by with heat pipe pump that the coaxial installation of engine works asynchronously in rotate and the working media of pumping, the heat that each heat-sensitive element in the engine is produced is carried outside and is imported the external world into, the temperature rise when guaranteeing that new power machine is safeguarded its normal operating conditions.The heat of carrying outside also can supply extraneous various applications.When heat pipe pump rotates with main frame except having the general industry pump characteristics, have the unique function that quite desirable heat is concentrated exchange simultaneously: the working medium in the heat pipe is after the inner at the heat-sensitive element place of main frame is heated and absorbs heat, be evaporated to the outer end of heat pipe pump, run into the working media of the low pump of temperature--take thermal medium, just turn back to the inner again after heat being transmitted out cooling, and so forth circulation.And heat pipe pump provides fluid dynamic for taking thermal medium, constantly see the working medium of heat exchange off and welcome the cold new thermal medium of taking, concentrated switching station or the intensive heat exchanger and the dual-use function of pump with heat, for main frame provide one with extraneous heat exchanger channels.This is for the engine of the petroleum geology exploration mining operations of working in be everlasting underground or pipeline, because local narrow, air mass flow is not enough to rely on the electromechanical motive equipment that conventional fan leaf refrigeration can't operate as normal particularly suitable.

Fig. 1 is the schematic diagram of a constructional device of the present utility model.

1 is the housing of engine among the figure, the 2nd, and the rotor of engine, the 3rd, the stator of engine, the 4th, heat pipe the inner, the 5th, heat pipe outer end (stator fin), the 6th, heat pipe outer end (rotor fin), the 7th, the heat pipe pump pump housing, the 8th, heat pipe pump inlet, the 9th, heat pipe pump outlet.Fig. 1 is a kind of in the various types of heat pipe pump.The utility model except stator and rotor are made up of the outer end fin of heat pipe, the structural similarity of remainder and general cantilevered industrial pump, the pump structure pattern can be made centrifugal pump, peripheral pump or mixed-flow pump according to the needs of condition of work.Shown among the figure that rotor of the present utility model is to install with the rotor coaxial of engine, both should keep synchronous working.All should there be the inner of a corresponding heat pipe to fit tightly at each magnetic pole unit of engine or the back side of other power heat-sensitive elements with it.When engine was worked, the utility model also constantly rotated pumping and takes thermal medium, makes it continuously mobile.As take thermal medium sufficient natural origin is arranged, can adopt the opening circulation, discharge after the heat pipe pump heat exchange that makes it to flow through; When not having the situation of natural source, can adopt sealing and circulating, be connected with the import and export of industrial heat exchange device respectively, can also utilize its heat with pipeline.The heat flow of taking thermal medium must keep with the duty of engine coordinating, and like this, by the flow of control valve control heat pipe pump, has just controlled heat flow indirectly, thereby has made it to guarantee balanced operation with dynamic host.

Heat-pipe working medium can be water, oil, fluorine Lyons, fluorine carbon various cryogenic fluids such as (or chlorine carbon), to adapt to the working condition requirement of different dynamic machine.For example heat-pipe working medium is replaced by cryogenic fluid, main power machines and heat pipe pump are more in addition after the insulation processing, the utility model is except being used for rare-earth permanent magnet motor or generator, also applicable to the condition of work of superconduction winding, as the superconducting apparatus of superconducting motor, rotation or the auxiliary device of other electromechanical equipments that have rotor with power thermal element.At this moment heat pipe should be contained between superconductor and the insulating barrier, therefrom heat is drawn engine and passes to and take thermal medium.In a word, the utility model provides more satisfactory attached heat-transfer equipment for the industrialization practical application of new power machines such as rare earth permanent magnet engine and superconducting motor.
