Semiconductor refrigeration device using normal temperature hydrologic cycle to cool

Abstract

The invention relates to a semiconductor refrigerator, comprising a lagging casing, a cold conducting body, a semiconductor refrigeration piece, a radiator, a fan, an inlet and outlet communicated externally, characterized in that the cold conducting body is composed of a plurality of cold conducting pieces, an upper and lower press cover that are fixed integrally by a screw and a nut to form a cooling system enabling the water at constant temperature to flow and cycle up and down; reducing water flow and directly enabling the water at constant temperature to flow to the cold conducting body and flow out after cycled and cooled in a cycle way in the cold conducting body. The invention is capable of ensuring balance of cold water temperature, effectively improving refrigerating efficiency and realizing continuously cold water supply that is rapid and convenient.

Description

technical field [0001] The invention relates to a semiconductor refrigerator, which is used in electronic refrigeration equipment, such as water dispensers, direct drinking machines, beverage dispensers, medical ice packs and the like. Background technique [0002] In the structure of existing semiconductor refrigerators, an inner tank is usually provided, which consists of a cavity, a cold guide body embedded in the side wall of the cavity, and a water inlet and outlet pipe connected to the outside at the top of the cavity. The side of the body facing the cavity is provided with many integrated cooling plates, and all surfaces of the cooling plates are exposed and immersed in the cavity; the diameter of the inlet and outlet pipes is relatively large, and the water flow is usually relatively large. The cooling method of the existing semiconductor refrigerator is to let normal temperature water flow into the inner tank cavity to fill it with water, and then rely on the cold c...

AI Technical Summary

Problems solved by technology

Because the distance between the water in the inner tank cavity and the surface of the cooling body is different, the cooling speed is very unbalanced. The cold exchange on the surface of the cooling body is the fastest. The cooling time is very long, and it will cause waste of cooling capacity and low cooling efficiency, because while cooling the water away from the surface of the cooling body, it is also continuously cooling the cold water that has reached the standard around the surface of the cooling body , making it colder and colder, and this kind of refrigeration is unnecessary. It is undoubtedly a waste to release the cooling capacity of this part of the cold water, and because the temperature of the cold water in the cavity is very uneven, the taste of drinking will be poor

In addition to the above, there is still a disadvantage in the prior art, that is, when the cold water is released, the normal temperature water flows into the inner tank cavity at the same time and mixes with the cold water rapidly, causing the amount of cold water released is far lower than the actual amount of cold water in the inner tank cavity volume , leading to the phenomenon of less cold water output
