Abstract
The invention discloses an anti-freeze heat exchanger. One or more heat conduction pipes are built in the shell of the anti-freeze heat exchanger; a working medium flows in the heat conduction pipes; water or an aqueous solution flows in the shell outside the heat conduction pipes; and a pressure relief device used for relieving the pressure on the shell is also arranged in the shell. The anti-freeze heat exchanger disclosed by the invention has the beneficial effects that volume expansion space is provided for freeze of water by utilizing a gas built-in method, thereby relieving the pressure on the pipe walls or the shell of the heat exchanger, and achieving the anti-freeze, non-deforming and non-cracking effects of the heat exchanger; meanwhile, a shell-and-tube heat exchanger design scheme which combines in-pipe fluorine flowing with inter-pipe water flowing is adopted, and thus the possibility that water flows into in-pipe closed fluorine systems is low even if the heat exchanger is frost-cracked; and accordingly, the in-pipe closed fluorine systems can be protected from further severer faults and problems caused by frost-cracking of the heat exchanger.
Description
Technical field
The present invention relates to heat exchange equipment technical field, particularly relate to a kind of anti-freezing type heat exchanger.
Background technology
Statement in this part merely provides the background information relevant with present disclosure, thereby increases and it is possible to do not constitute prior art.
The usual heat exchanger carrying out heat exchange with water cannot resistance to freeze, during water congeals into ice, ice concentration is little thus volumetric expansion occurs, frequently can lead to the malignant problem that heat exchanger is split up, for with the refrigeration of compressor or heat pump, heat exchanger is split up and may proceed to produce water and enter refrigerant pipeline and compressor, cause whole equipment to be paralysed the serious consequence that cannot repair.Product in the market does not has good solution to this.
Therefore prior art haves much room for improvement and develops.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method utilizing built-in gas and build-ups ice offer volumetric expansion space for water, relaxes the anti-freezing type heat exchanger of the pressure of exchanger tube wall or housing carrying.
The technical solution of the present invention is:
A kind of anti-freezing type heat exchanger, its housing is built-in with heat pipe, and a kind of fluid working substance flows in housing from heat pipe of heat conduction Bottomhole pressure, water or aqueous solution, is the most also placed with the slow pressure device for slowing down the pressure that housing is born in this housing.
Described delaying press-fits the air bag being set to carry preset volume gas.
Described delaying press-fits the pocket being set to gather air.
Described slow press-fit the ad-hoc location being set to by arranging heat exchanger interface and directly allow the top of housing become a special pocket gathering air, preserve portion of air.
The version of the pocket gathering air is one or more shape cavity-like thing as the cup of back-off, or connect the cavity-like thing of the cup of the shape such as back-off of bunchiness, each cavity-like thing has one or more accent, accent down or is distributed in the bottom of cavity-like thing, can put aside the gas of certain capacity in ensureing cavity, in the opening size of accent ensure that cavity-like thing simultaneously, exterior fluid flow is unobstructed.
This heat exchanger has 4 interfaces, includes water inlet and outlet, the also inlet and outlet of the working medium of Bottomhole pressure.
The heat pipe of this heat exchanger can be metal material, it is also possible to be the non-metallic material that heat conductivility is good；Heat pipe can be common light pipe, it is also possible to be to be threaded, with ribbed pipe or with the high-efficiency heat-transfer pipe of fin.
Beneficial effects of the present invention:
Anti-freezing type heat exchanger disclosed by the invention utilizes the method for built-in gas to build-up ice for water and provides volumetric expansion space, relaxes exchanger tube wall or the pressure of housing carrying, reaches heat exchanger effect freeze proof, indeformable, indehiscent.Simultaneously, owing to walking the shell-and-tube heat exchanger design leaked water between fluorine, pipe in present invention pipe, even if generation heat exchanger is by the problem of bursting by freezing, in pipe, airtight fluorine system is not easy to into water, so that system will not produce further worse fault and problem because of heat exchanger bursting by freezing.
Accompanying drawing explanation
Fig. 1 is the embodiment of the present invention 1 structural representation；
Fig. 2 is the embodiment of the present invention 2 structural representation.
Detailed description of the invention
Embodiment:
Refering to Fig. 1, a kind of anti-freezing type heat exchanger, it includes housing 1 and the copper pipe 2 being arranged in housing 1.
Water inlet 5 and outlet 3 are arranged on housing 1, and outlet 3 is positioned at the top of water inlet 5, and i.e. outlet 3 is higher than water inlet 5.The two ends entering fluorine mouth 6 and go out fluorine mouth 4 and lay respectively at copper pipe 2, enter fluorine mouth 6 position and are higher than fluorine mouth 4.
The anti-freezing type heat exchanger that the technical program provides is that shell-and-tube heat exchanger [a1] refrigeration working medium of built-in heat conducting pipe or other heat-exchange working mediums are from heat conduction Bottomhole pressure, flow in water or the aqueous solution housing from heat pipe, the most also it is placed with in this housing and carries the air bag of certain volumetric gas or be placed with and gather the pocket of air or directly allow the top of cavity preserve portion of air by arranging the ad-hoc location of heat exchanger interface, or have two or three form in scheme above simultaneously concurrently.
Preferably, the version of the pocket gathering air is one or more shape cavity-like thing as the cup of back-off, or connect the cavity-like thing of the cup of the shape such as back-off of bunchiness, gap or hole is left, it is ensured that in each cavity-like thing, exterior fluid flow is unobstructed between accent and the next cavity-like thing of each cavity-like thing.
Further, heat exchanger has 4 interfaces, includes water inlet and outlet, also has the inlet and outlet of another kind of working medium.The heat pipe of this heat exchanger can be metal material, it is also possible to be the non-metallic material that heat conductivility is good；Heat pipe can be common light pipe, it is also possible to be to be threaded, with ribbed pipe or with the high-efficiency heat-transfer pipe of fin.
Fig. 1 is anti-freezing type heat exchanger embodiments one.In the present embodiment, certain distance is arranged at outlet 3 and housing 1 top, thus in real work heat transfer process, the interior part more than outlet of housing 1, have the air that respective volume cannot be got rid of stationed, form natural pocket.During the present embodiment provides the benefit that the water in housing 1 build-ups ice, mixture of ice and water can the pocket to top expand, and effectively slows down the pressure that housing is born, thus finally realizes the performance that heat exchanger is freeze proof.
Fig. 2 is anti-freezing type heat exchanger embodiments two.On the basis of embodiment one, the present embodiment adds string pocket string 7 in housing, so design has an advantage that, also put aside gas in pocket string 7 simultaneously, during water freezing, mixture of ice and water can the most upwards portion's pocket and middle pocket string expand, while effectively slowing down the pressure that housing is born, such being designed with beneficially reduces the deformation expanding the internal heat pipe of the heat exchanger brought because of ice body, thus the anti-freezing property of further effective guarantee heat exchanger.
