Description
Technical field
The utility model relates to water dispenser, especially a kind of water dispenser with semiconductor refrigerating.Be applicable on the little product of the water dispenser of various styles or refrigerator refrigerating capacity.
Background technology
Semiconductor has electric current to pass through to produce pyroelectric effect (paltie effect), a semi-conductive side temperature is low when promptly switching on, the phenomenon that the opposite side temperature is high, people's facility has been invented a kind of cost simple in structure low refrigeration or heater with semiconductor, and be widely used in water dispenser, on the little product of refrigerating capacitys such as automobile refrigerator.
Semi-conducting material has higher thermoelectrical potential can be used for making the mini thermoelectric heat refrigerator.Shown in Figure 1 is the thermocouple refrigeration element that N-type semiconductor and P-type semiconductor constitute.With copper coin and copper conductor N-type semiconductor and P-type semiconductor are connected into a loop, copper coin and copper conductor only play conduction.At this moment, a contact heating, a contact turns cold.If the sense of current is reverse, the cold and hot effect reciprocity at node place so.
The cold bladder structure that adopts at present semiconductor refrigerating on water dispenser as shown in Figure 1 and Figure 2, its operation principle is that semiconductor chilling plate 6 energising backs are delivered to cold courage 5 metal shells near cold courage one side temperature reduction and with cold, opposite side temperature near radiator 1 raises, with heat transferred radiator 1, forced refrigeration by fan 7 is taken away heat, and the water of cold courage inside begins to cool down, and arrives certain temperature up to water temperature, the electronic temperature control device is deenergization just, quits work.The shortcoming that the water dispenser of this structure exists is: 1) in the process of refrigerastion, by free convection, the water temperature gradient is bigger fully for the water of cold courage inside, and promptly the bottom water temperature is low, top water temperature height, and cause the volume of cold courage inner cryogenic water less; 2) because free convection is very slow, cause freezing at the semiconductor chilling plate near zone in the process of refrigerastion, and ice sheet has hindered the cold of cooling piece and the heat exchange between the cold courage internal water as an insulator, so just reduced refrigerating efficiency, prolonged cooling time, the water temperature of the cold courage inside that causes working long hours does not also drop to the shutdown temperature that electronic temperature control is set; 3) existing radiator all is the section bar of disposable aluminium drawing and forming, and its heat transfer efficiency is lower than fin such as copper materials, and especially when temperature was higher, semiconductor chilling plate was not gone out and refrigerating efficiency decline owing to heat looses, and has prolonged the working time.
Summary of the invention
The technical problems to be solved in the utility model is: provide that a kind of heat exchange is fast, refrigerating efficiency is high, even water temperature and the water dispenser with semiconductor refrigerating abundant, long service life in the cold courage.
The technical scheme that the utility model adopted is: with the water dispenser of semiconductor refrigerating, cold courage with metal material, its outside is surrounded by heat-insulation layer, this cold courage is provided with and leads to outside water inlet pipe and outlet pipe, on a face of cold courage, radiator is housed, be provided with semiconductor chilling plate between the contact-making surface of radiator and cold courage, and fan be housed, it is characterized in that being connected a water circulating pump that is positioned at cold courage outside with pipeline corresponding between the top of the installation site of cold courage and the bottom in the outside of radiator.
On described radiator, be slightly larger than described semiconductor chilling plate and the surperficial copper billet that flushes with the bottom of radiator corresponding to the embedded area in the position of semiconductor chilling plate.
Described radiator is a rib-type rectangle radiator, and described copper billet is embedded in the centre of radiator bottom.
Described radiator is a heat-pipe type radiator, and what contact with semiconductor chilling plate is a copper billet that the bottom surface polishes, and its both sides are welded some heat-conducting copper pipes respectively, and the upper end of heat-conducting copper pipe is welded with one group of aluminium fin.
The beneficial effects of the utility model are: 1) because water circulating pump has been installed, when cold courage is worked, water circulating pump is also started working, allow the water of cold courage inside begin forced convertion, the cooling piece near zone just can not form ice sheet like this, and all relative temperature difference is less to make the water temperature of whole cold courage inside, and there was not temperature difference basically in cold courage water temperature inside after so once refrigeration was finished, effectively the cold water volume is big, has improved refrigerating efficiency.2) embed a copper billet in the middle of the rib-type rectangular aluminum section bar of traditional one-off drawing, the bottom surface polishes, and has increased thermal conductivity factor like this, has improved radiating efficiency; And another kind of heat-pipe type radiator, the heat transfer efficiency of heat-conducting copper pipe is very high, and the surface area of aluminium fin is very big again, and radiating efficiency improves a lot under the situation of air blast cooling.
