Abstract
The present invention provides an ecological thermoelectric refrigerating system comprised of a thermoelectric plate by coupling to the latter a supplementary metal plate on the cold generating face (1) and two dissipators, one dissipator being arranged on the supplementary metal element and the other dissipator being refrigerated by natural or forced convection to the heat generating face (2). In order to avoid the thermal bridge between both faces and in order to provide mechanical rigidity to the assembly an isolating material is mounted between the two dissipators.
Description
Refrigerating system of the present invention comprises the refrigerating assembly of the full ecological formula made from the semiconductor element that can buy on market.For this reason, must develop a kind of hot conducting system, make the energy generation maximum effect of generation, to obtain not contain the still ignorant performance level in gas refrigeration (ecological type refrigeration) field so far.
Assembly comprises the thermoelectric plate of the sort of type that can buy on market, set up a metal adapter on it, preferably made of aluminum, it sets up a side that is being used to freeze: together with two dissipators, one is positioned at the thermal transpiration side, and another is positioned at the free side of metal adapter.
(thermoelectric plate and adapter between the surface of being discussed; Thermoelectric plate and dissipator 1; Free side of metal adapter and dissipator 2) between perfection to contact be very important.For this reason, suggestion uses some high conduction performance material (for example silicon or copper sulphate) guaranteeing high-quality contact, thereby avoids occurring the thermal resistance that is harmful to therebetween.
Another key point is the especially design of its thermal transpiration side of design of its dissipator in the above-mentioned refrigerating system.Assembly of the present invention has used our design, and the dissipator can buy on the market.Purpose to the modification that it carried out is to reduce as far as possible thermal resistance (dissipator-atmosphere) in order to forced convertion work.With its machined, its base portion reduces to 4mm for this reason, and wherein the fin width reduces to 2mm, and this fin is still fully straight simultaneously.Consequently, with one with air when in the past the tube-axial fan of top blast to dissipator worked, we have obtained the thermal resistance of 0.05 ℃/W.As described above, air must positive blow to form maximum turbulent flow, can use the low blade profile fan that can buy on the market.
For obtaining the mechanical rigid of assembly, need to adopt the supporting arrangement of some form.When reaching this purpose, can not between refrigeration side and thermal transpiration side, form any type of thermal bridge.Must consider the following fact, if promptly this abnormal phenomena takes place by (for example owing to using metal bolts and nut to bring) really, then the loss that it caused is a large number (about 32%).Exactly because this reason, the necessary screw bolt and nut that adopts heat insulator perhaps must adopt a kind of intermediate plate of being made by insulating materials, and metallic rod is passed this plate and used bolting in staggered mode from each dissipator.We have adopted this second scheme.
As an example of refrigerating system of the present invention, Fig. 1 shows a kind of improved prototype, and it comprises that one stores the container of liquid (such as water), six refrigerating assemblies are divided into two groups, every group three, be separately fixed at its two opposite sides, and allow dissipator and refrigeration side 1 stay in the container.The dissipator that has thermal transpiration side 2 is retained in the outside, assists down at low blade profile tube-axial fan 3 and carries out work in the forced convertion mode.Three refrigerating assemblies of above-mentioned each group make air-flow in the place ahead of fan channeling conduct by small nozzle with two this fans simultaneously.
The mechanical rigid of each refrigerating assembly reaches through two dissipators are linked up with as shown in Figure 2 method.Can see the part of being made by insulating materials 1 in this figure, be embedded in the metallic rod 2 in this part in addition in addition, these bars do not contact each other, have avoided the generation of thermal bridge.
Can adopt the dc source that to buy on the market to guarantee to power to refrigerating assembly.In Implementation Modes that this determines, can comprise that one is formed in and forms as a whole power supply in the system.
In this prototype, assembly is equipped with the plate of 60W, when environment temperature is 30 ℃, can obtain following temperature:
Cold-side temperature=-10 ℃
Hot side temperature=33 ℃
Water temperature=-2 ℃
If the cooling coil of a kind of beverage dispenser (for example being used for beer or soft drink data distribution device) is installed in this device, then this liquid can be cooled to a certain suitable temperature.
In the advantage of native system, can arrive out following some:
---do not use the cooling gas just can refrigeration.
---there is not moving component (except that fan).
---high-performance.
---supply voltage is low.
---system architecture is simple, thereby makes it very compact.
---flexibility is strong, repacking easily, wide adaptability.
