Abstract
The utility model relates to a semiconductor refrigerator which is suitable for every industry or trade and families of ordinarily resident. The semiconductor refrigerator mainly comprises a box body, a cold-storage appliance, a refrigerator, a fan, a radiator, a water evaporator and a water tank. A cooling airflow enters from the lower part of the radiator, after absorbed heat by the radiator, and the cooling airflow on the upper part of the radiator and is discharged by the fan. Rib fins of the radiator adopt a copper plate of 0.3 to 0.4 millimeter to form the shape of U, and rib faces are wavy. An intake air port of the lower part of the radiator is provided with the water evaporator. The semiconductor refrigerator causes the temperature of 10 liter to 20 liter volume to reach about 0 DEG at the environment temperature of 40 DEG.
Description
The utility model relates to the mini-bar of daily life and all trades and professions use, particularly a kind of semiconductor freezer.
At present, the semiconductor refrigerating mode, owing to have pollution-free, noiselessness, particularly be higher than distinct advantages such as other refrigeration modes with its efficient of cold occasion little, more and more be subjected to common concern, but the conductor refrigeration refrigerator of the present wind-cooling heat dissipating form of using, since the air flow direction of cooling system and version can not be effectively with the heat dissipation in the hot junction of semiconductor cooler, thereby seriously influenced the refrigerating efficiency of semiconductor cooler, because the quality of heat radiation is the key of decision refrigerating efficiency quality, so make the product of this refrigeration mode can not get developing widely.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and the semiconductor freezer of a kind of high efficiency and heat radiation system is provided.
How the purpose of introducing utility model below in conjunction with accompanying drawing realizes.
Fig. 1 is the structural representation of utility model.
Fig. 2 is a radiator fin schematic diagram.
Basic conception of the present utility model just provides a kind of high efficiency and heat radiation system, and this system is by radiator 5, water evaporimeter 6, and fan 4 forms. Cooling blast and the flow direction adopt and are entered by radiator 5 bottoms, after radiator 5 heat absorptions, are discharged by the fan 4 on radiator top, have eliminated like this short circuit phenomenon of cooling blast, and heat-sinking capability is obviously improved.
Radiator 5 is that finned surface is made waveform at a metallic plate 9 welding U-shaped shape fins 8, with the disturbance that strengthens cooling blast with increase the area of dissipation that facings the wind, heat-sinking capability is obviously improved.
Water evaporimeter 6 is installed in the air inlet place, bottom of radiator 5, and evaporimeter 6 is the water sucking-off in the water tank 7, under the effect of air inlet wind-force with moisture diffusion and act on radiator 5 and after absorbing heat, discharge by fan 4.
The utility model is simple in structure, and is easy to manufacture, and the noiselessness friction uses maintenance side to make the reliability height.Because heat radiation fully can make refrigerator 3 refrigerating efficiencies improve 30%.When input power 60W fan power is 5W-7W, 10 liters-20 temperature in the liter capacity are reached about 0 ℃.
Introduce embodiment of the present utility model below.
Enforcement of the present utility model does not have specific (special) requirements, and all other parts prior aries all can solve and outsourcing, and radiator fin 8 can be pressed into the U shape with the 0.3-0.4mm copper coin, and the finned surface waviness is welded on the metallic plate then.Water evaporimeter 6 usefulness absorbent materials are made, and water tank 7 is made of plastic, and the 1st, casing, the 2nd, cold accumulator is made with metal material.Radiator 5 and cold accumulator 2 are filled with heat-barrier material around the refrigerator 3, and relevant installation can be carried out with reference to accompanying drawing.
Using method of the present utility model: connect the 12V dc source, electric current 3A-5A can use, 130 kilocalories per hours of refrigerating capacity.When environment temperature is higher than 30 ℃, water is added in the water tank 7, can play the enhance heat effect.When environment temperature is lower than 30 ℃, add water or do not add water and all can obtain better radiating effect.Refrigerator should clean water evaporimeter after using a period of time, to guarantee that refrigerator can carry out work under best radiating state.
