Abstract

The utility model discloses a high efficiently forced heat exchange electric heater, comprising a (micro)circulating pump(1), internal heat conducting fins(2), a TEC heat energy converter(3), a fan(4), external heat conducting fins(5), a liner body(6), a heat insulation layer(7), a water inlet pipe(8) and a water outlet pipe(9), etc., wherein water(or fluid) enters the liner body(6) from the water inlet pipe(8), the (micro)circulating pump(1) drives water(or fluid) to flow repeatedly circularly on the internal heat conducting fins(2) so as to realize the rapid and forced heat exchange; the TEC heat energy converter(3) realizes the heat exchange of the internal heat conducting fins(2), and the fan(4) realizes the heat dissipation of the external heat conducting fins(5); liquid after the forced heat exchange flows out of the water outlet pipe(9); in another condition, the circulating pump(1) is arranged outside the liner body(6) and the heat insulation layer(7). Because of the forced driving actions of the circulating pump, phenomena of ice barrier and frost crack, etc. of the liner body can be effectively controlled.

Description

Cold, the warmer of a kind of high effect forced heat exchange electronics

Technical field

The utility model relates to electronic cooling (or heating) system in a kind of small household electrical appliance, especially relates to cold, the warmer of a kind of high effect forced heat exchange electronics.

Background technology

In the market production and selling have electronic cooling (or heating) function water dispenser and a cold drink device because the inner TEC heat converter size that electronic refrigerator adopted is less, and heat flow density is very high; In addition, the cooling piece TEC specification of selecting for use usually on the water dispenser is 4 * 4cm ²Thereby the heat transfer area that is in contact with one another with heat transmission fin is very little, particularly the heat exchange area of internal heat transfer fin is little, heat flow density is big, thereby the generation that thermal resistance such as cause easily freezing sharply increases phenomenon, more aggravated heat transfer rate slowly and refrigerating efficiency lowly, thereby be difficult to realize fast-refrigerating.And shortcomings such as the electronic cooling that generally adopts at present script refrigerating capacity and coefficient of refrigerating performance are less cause machine to be worked for a long time, and it is also bigger than motor compression refrigerator on the contrary to consume energy.Sometimes in order to obtain bigger refrigerating capacity, have to select for use the cooling piece TEC more than two, and do one's utmost to increase the area of thermofin, thereby caused that system architecture complexity, power consumption are big, product cost is on the contrary than the also high shortcoming of motor compression refrigerator.

The utility model content

The purpose of this utility model is to provide that a kind of cost is low, compact conformation, refrigeration (or heating) speed are fast, go out cold, the warmer of high effect forced heat exchange electronics that the cold water ability is big, prevent multiple advantages such as freezing stifled, the bursting by freezing of courage body internal junction.

For realizing above purpose, the utility model provides a kind of high effect forced heat exchange electronics cold, warmer, and comprising: annexes such as (miniature) circulating pump, internal heat transfer fin, TEC heat converter, fan, external heat transfer fins, courage body, heat-insulation layer, water inlet pipe and outlet pipe are formed jointly; Wherein water inlet pipe, outlet pipe and internal heat transfer fin are installed in courage body inside.Miniature circulating pump directly is installed at courage body inside or heat-insulation layer outside.Skin at the courage body tightly adheres to heat-insulation layer, and heat converter is installed between heat-insulation layer, and the outside links to each other with external heat transfer fins, and its inboard links to each other with the internal heat transfer fin; The direct frame of fan is contained on the external heat transfer fins, and external heat transfer fins is installed in the outside of heat-insulation layer.(miniature) circulating pump that wherein installs additional is to be used for promoting water to circulate repeatedly on the internal heat transfer fin of high heat flux and realize forced heat-exchanging; Thereby reach purpose supper-fast, super large refrigeration (or heating) ability.Simultaneously,, can prevent from effectively seriously to freeze on the courage body internal heat transfer fin, thereby avoid icing the generation of blocking up phenomenons such as not water outlet owing to the pressure impetus of circulating pump.

In the small household appliances such as the high effect forced heat exchange electronics of the utility model is cold, warmer can be widely used in water dispenser, cold drink device, Vending Machine, have compact conformation, refrigeration (or heating) speed is fast, capacity of outlet water is big, prevent multiple remarkable advantage such as the stifled not water outlet of the inner ice of courage body.

The specific embodiment:

Accompanying

drawing

1,2 has provided the embodiment of the utility model in the water dispenser refrigeration, specifically comprises:

(miniature) circulating pump 1, internal heat transfer fin 2, TEC heat converter 3, fan 4, external heat transfer fins 5, courage body 6, heat-insulation layer 7, water inlet pipe 8 and outlet pipe 9 etc. are common to be formed; As shown in Figure 1, water (or fluid) enters in the courage body 6 from water inlet pipe 8, on internal heat transfer fin 2, circulate repeatedly and realize forced heat-exchanging by promote water (or fluid) with (miniature) circulating pump 1, wherein heat converter 3 is housed 7 of heat-insulation layers, its inboard links to each other with thermofin 2 and heat exchange, the outside is connected with external

heat transfer fins

5,4 in fan externally dispels the heat on the thermofin 5, heat-insulation layer 7 is used for realizing liquid after the heat exchange in the courage body is realized insulation that liquid flows out from outlet pipe 9 after the heat exchange.The pump housing that contacts with water in (miniature) circulating pump 1 that installs additional on it all is the immersible pump that adopts the FDA food grade materials to make with crossing water lines.Shown in Figure 2 is that (miniature) circulating pump 1 is installed in the application examples outside the heat-insulation layer 7.Under the forced flow effect of (miniature) water pump, can obtain ultralow water temperature near freezing point, can control effectively again that to produce ice in the courage stifled, the generation that can also stop thermal resistance such as icing sharply to increase phenomenon simultaneously.Improve heat transfer rate and chilled water ability greatly, thereby realized fast-refrigerating.
