Abstract

The utility model discloses an efficient heat exchanger, comprising an inner pipe, an outer pipe, a (micro-) circulating pump, a non return valve and other accessories, wherein, the inner pipe is encased in the outer pipe, a channel which the heat exchange area can adopt completely is formed between the inner pipe and the outer pipe, the (micro-) circulating pump and the non return valve are arranged between a water inlet and a water outlet of the heat exchanger, the water flows from an intake of the outer pipe, the refrigerating medium flows from an intake of the inner pipe and does the relative flow or the opposite flow between the inner pipe and the outer pipe, thereby realizing the heat exchange to fulfill the purpose of refrigerating (or heating); or, the water flows from the intake of the inner pipe, the refrigerating medium flows from the intake of the outer pipe, at the time the circulating pump and the non return valve are arranged between the intake and an outlet of the inner pipe, that is the water pipe; when the size of the structure of the heat exchanger is small and the heat exchanger is short, the micro-circulating pump can be adopted to push the water to circularly flow again and again inside the heat exchanging pipe in order to realize the enforced heat exchange, thereby fulfilling the purpose of having the ability of ultra-high speed and ultra-refrigerating amount (heating).

Description

A kind of high-performance heat exchanger

Technical field

The utility model relates to refrigeration or the heating in a kind of electric equipment, especially relates to a kind of high-performance heat exchanger in the small household appliances.

Background technology

Production and selling has the refrigeration or a small household appliances of heat-production functions in the market, its inner heat exchanger is the heat exchanger that adopts patterns such as tube-sheet type, threaded pipe type or the external touch of tube and tube mostly, because the heat exchange area that is in contact with one another is less, reasons such as the thermal contact resistance that mutually combines is bigger have caused heat transfer efficiency comparatively low.When particularly being applied on the evaporimeter in the refrigeration system, no matter the heating system of comparing is in power, refrigerating capacity, or on the temperature difference of the evaporating temperature and the medium that is cooled, all is far smaller than heating system.Because the deficiency of the refrigerating capacity and the temperature difference has caused heat exchange efficiency very not good, and the generation that process of refrigerastion often sharply increases phenomenon with frosting, thermal resistance such as freeze again, thereby more aggravated heat transfer rate slowly and refrigerating efficiency lowly, thereby can't realize fast-refrigerating.Sometimes in order to obtain bigger refrigerating capacity, have to do one's utmost to increase heat exchange area, select more powerful refrigeration machine for use, the result has caused that system is huge, complex structure, equipment cost are too high, be difficult to unfavorable factors such as popularization.

The utility model content

(pipe middle sleeve formula) high-performance heat exchanger that the purpose of this utility model is to provide a kind of compact conformation, heat exchange efficiency height, anti-part to freeze stifled (or heating partial vaporization, boiled).

For realizing above purpose, the utility model provides a kind of high-performance heat exchanger, comprises that annexes such as interior pipe, outer tube, (miniature) circulating pump and check valve form jointly.Wherein, interior pipe box forms the passage that heat exchange area can all utilize between the inner and outer pipe in outer tube; (miniature) circulating pump and check valve are installed between the water inlet and delivery port of heat exchanger.Water flows into from outer tube inlet, and cold-producing medium flows into from interior tube inlet, and cold-producing medium and water are done relatively between inner and outer pipe or flowed in opposite directions, thereby realizes that heat exchange is to reach the purpose of refrigeration or heating; Another kind of situation, water flows into from interior tube inlet, and cold-producing medium flows into from outer tube inlet, and pipe was between the import and export of water pipe in circulating pump and check valve were installed at this moment.When the structure that need dwindle heat exchanger significantly or the size of heat exchanger, length equidimension very little, in the time of need rolling up exchange capability of heat, can utilize miniature circulating pump promotion water in heat exchanger tube, to circulate repeatedly and realize forced heat-exchanging, thereby reach purpose supper-fast, super large refrigeration (or heating) ability.Simultaneously, because the pressure impetus of circulating pump can effectively suppress the deposition of solia particle on the surface, has very good resistive connection dirt performance.

No matter the utility model heat exchanger is used in refrigeration or the heating, all can realize high efficient heat exchanging with water, can be widely used in as in the small household appliances such as water dispenser, cold drink machine, Vending Machine, small air-conditioning system, have big, the anti-icing stifled and anti-partial vaporization or boiled of compact conformation, heat exchange efficiency height, refrigeration or heating capacity, and have remarkable advantages such as anti-fouling tendency is good.

Description of drawings

Fig. 1 and Fig. 2 are the utility model internal structure schematic diagrames.

The specific embodiment:

As shown in Figure 1, pipe 1, outer tube 2, (miniature) circulating pump 3 and check valve 4 etc. were formed jointly in the utility model heat exchanger comprised.Wherein, interior pipe 1 is enclosed within the outer tube 2, miniature circulating pump 3 and check valve 4 are installed between the water inlet and delivery port of heat exchanger, water flows into from outer tube 2 inlets, cold-producing medium flows into from interior pipe 1 inlet, cold-producing medium and water are done relatively between inner and outer pipe or are flowed in opposite directions, thereby realize that heat exchange is to reach the purpose of refrigeration or heating.Another kind of situation as shown in Figure 2, water flows into from interior pipe 1 inlet, cold-producing medium flows into from outer tube 2 inlets, this moment circulating pump 3 and check valve 4 be installed in pipe 1 be between the import and export of water pipe.When the structure size of heat exchanger and length design are very little, can utilize miniature circulating pump 3 to promote water and in heat exchanger tube, circulate repeatedly and realize forced heat-exchanging, thereby reach purpose supper-fast, super large refrigeration (or heating) ability.And under the forced flow effect of water pump, can obtain ultralow water temperature (or high water temperature of nearly boiling point) near freezing point.Can control simultaneously the interior water refrigeration part of heat exchanger tube again effectively and freeze the generation of stifled (or heating partial vaporization, boiled) phenomenon.

Claims
