Abstract

The utility model discloses a rapid refrigerating evaporator which is composed of an inner pipe, an outer pipe, a mini-type circulating pump and a one-way valve together, wherein the inner pipe is sleeved in the outer pipe, a passage whose heat exchanging area can be completely utilized is formed between the inner pipe and the outer pipe, the mini-type circulating pump and the one-way valve are installed between a water inlet and a water outlet of an evaporator, water flows inwards from an inlet of the outer pipe, coolant flows inwards from an inlet of the inner pipe, the coolant and the water flows relatively or oppositely between the inner pipe and the outer pipe, thereby realizing heat exchange to achieve the purpose of rapid refrigeration, the rapid refrigerating evaporator not only can obtain the ultra-low water temperature close to the freezing point, but also can effectively control the occurrence of water refrigeration local freezing phenomena in the heat exchanging pipe simultaneously, and can be widely used in the fields of mini-type household electrical appliances such as drinking machines, cold drink machines, vending machines and the like.

Description

The fast-refrigerating evaporimeter

Technical field

The utility model relates to the rapid refrigerating system in a kind of home appliance, especially relates to a kind of fast-refrigerating evaporimeter in the water dispenser.

Background technology

The small household appliances that have refrigerating function of production and selling in the market, its inner evaporimeter is to adopt tube-sheet type mostly, modes such as threaded pipe type or the external touch of tube and tube are conducted heat, because the heat transfer area that is in contact with one another is less, reasons such as the thermal contact resistance that mutually combines is bigger, caused heat transfer efficiency comparatively low, when particularly being applied on the evaporimeter in the water dispenser refrigeration system, its heating system of comparing, no matter be at power, refrigerating capacity, still on the temperature difference of the evaporating temperature and the medium that is cooled, all be 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 process of refrigerastion is often again with frosting, the generation that thermal resistance such as freeze sharply increases phenomenon, 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, the heat exchange area of having to do one's utmost to increase, select more powerful refrigeration compressor for use, the result has caused system huge, complex structure, equipment cost is too high, be difficult to unfavorable factors such as popularization.

The utility model content

The purpose of this utility model is to provide a kind of compact conformation, heat exchange efficiency height, can prevents the local icing stifled fast-refrigerating evaporimeter that freezes.

For realizing above purpose, the technical solution adopted in the utility model is:

The fast-refrigerating evaporimeter is made of jointly interior pipe, outer tube, miniature circulating pump and check valve, and 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 evaporimeter, water flows into from outer tube inlet, 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 fast-refrigerating; 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 evaporimeter significantly or the size of evaporimeter, length equidimension very little, in the time of need rolling up refrigerating capacity, can utilize miniature circulating pump promotion water in heat exchanger tube, to circulate repeatedly and realize forced heat-exchanging, thereby reach purpose supper-fast, the super large refrigerating capacity.Simultaneously, because the pressure impetus of circulating pump, can prevent effectively that local freezing from freezing stifledly, and suppress the deposition of solia particle, have very good resistive connection dirt performance on the surface.

The utility model fast-refrigerating evaporimeter can be widely used in as in the small household appliances such as water dispenser, cold drink machine, Vending Machine, and it is big, anti-icing stifled to have a compact conformation, heat exchange efficiency height, refrigerating capacity, and has remarkable advantages such as anti-fouling tendency is good.

Description of drawings

Fig. 1 is installed in structural representation between water inlet and the delivery port for miniature circulating pump and check valve;

Fig. 2 is installed in structural representation between the import and export of water pipe for miniature circulating pump and check valve;

The specific embodiment:

As shown in Figure 1, the fast-refrigerating evaporimeter by interior pipe 1, outer tube 2,, miniature circulating pump 3 and check valve 4 form, 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 evaporimeter, and water flows into from outer tube 2 inlets, and 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 fast-refrigerating.

As shown in Figure 2, water flows into from interior pipe 1 inlet, and cold-producing medium flows into from outer tube 2 inlets, and pipe 1 was between the import and export of water pipe in miniature circulating pump 3 and check valve 4 were installed at this moment.When the structure size of evaporimeter 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, the super large refrigerating capacity.

The utility model can obtain the ultralow water temperature near freezing point under the forced flow effect of miniature circulating pump; Can control simultaneously the local generation of freezing stifled phenomenon of water refrigeration in the heat exchanger tube again effectively, can be widely used in as small household appliances fields such as water dispenser, cold drink machine, Vending Machines.

Claims

1. the fast-refrigerating evaporimeter is made of jointly interior pipe, outer tube, miniature circulating pump and check valve, it is characterized in that: pipe box forms the passage that heat exchange area can utilize fully in described between interior pipe and the outer tube in outer tube.

2. fast-refrigerating evaporimeter according to claim 1 is characterized in that: described miniature circulating pump and check valve are installed between the water inlet and delivery port of evaporimeter.
