Problems solved by technology

However, compared with other refrigeration methods such as compressor refrigeration, electronic refrigeration has the disadvantages of low refrigeration efficiency, low refrigeration power, and low cooling capacity.
[0003] The existing ordinary electronic refrigeration system is generally composed of three main components: electronic refrigeration chip, heat dissipation device, and cooling device. When it is applied to refrigeration and cooling equipment such as small air conditioners, the electronic refrigeration chip has low cooling efficiency and small cooling capacity The cooling capacity on the cooling device cannot effectively cool the air passing through it, resulting in the disadvantage of small temperature difference and inconspicuous effect

[0019] see figure 1 , an electronic refrigeration device that can store cold, including an electronic refrigeration chip 1, a heat sink that is close to its hot surface, and a radiator 3 that is close to its cold surface. Cold storage tank 4, cold storage tank 4 is made up of cold storage liquid tank 5 and air tank 6 arranged at intervals, and cold storage tank 4 is equipped with cold storage liquid 7 capable of storing cold.

[0020] The radiator 3 is a finned radiator, and the cold storage tank 4 is hollow fin-shaped corresponding to it, and the fins of the radiator 3 extend into the cooling liquid tank 5 of the cold storage tank 4 . Wherein, the number of cold storage liquid tanks 5 in this embodiment is 5 groups, and the number of cold storage liquid tanks 5 can be adjusted accordingly according to needs and actual conditions. The cold storage liner 4 is made of plastic, preferably, it can specifically adopt PP, PV, PE, etc., and the wall thickness is relatively thin. Du...

[0025] see figure 2 The main difference between the electronic refrigeration device capable of storing cold and the first embodiment is that the radiator is an air-cooled radiator. The air-cooled radiator is specifically a finned air-cooled radiator 21 with a side close to the hot surface of the electronic cooling chip 1 , and a cooling fan 22 is connected to the finned air-cooled radiator 21 . When this embodiment works, the heat generated by the electronic cooling chip 1 can be transferred to the air-cooled radiator 21, and the cooling fan 22 works at the same time to generate convective air to exchange heat with the air-cooled radiator 21 to complete heat dissipation.

[0026] Other unmentioned parts are the same as the first embodiment and will not be repeated.

Abstract

The invention discloses an electronic refrigerating device capable of accumulating cold. The electronic refrigerating device comprises an electronic refrigerating chip, a heat radiator clinging to the hot surface of the electronic refrigerating chip, a cold radiator clinging to the cold surface of the electronic refrigerating chip and a cold accumulation container connected with the cold radiator, wherein the cold accumulation container is composed of a cold accumulation liquid tank and an air duct, and cold accumulation liquid capable of accumulating cold is filled in the cold accumulation container. The cold radiator is a fin type cold radiator, the cold accumulation container is of a fin shape corresponding to the cold radiator, and a fin of the cold radiator extends into the cold accumulation liquid tank of the cold accumulation container. The heat radiator is a water cooling heat radiator or an air cooling heat radiator. When the electronic refrigerating device provided by the invention works, cold energy generated by the electronic refrigerating device can be transmitted into the cold accumulation liquid in the cold accumulation container through the cold radiator and stored. When refrigeration is required, air can pass through the air duct through blowing and exchange heat with the cold accumulation liquid through the wall of the cold accumulation liquid tank, and the cold accumulation quantity of the cold accumulation liquid is large, therefore, the air can be remarkably cooled for a long time. By using the electronic refrigerating device, the defects of small refrigeration quantity and unremarkable cooling effect of a semiconductor refrigerating device in the prior art can be effectively overcome.

Description

technical field [0001] The invention relates to an electronic refrigeration device, in particular to an electronic refrigeration device capable of storing cold. Background technique [0002] Electronic refrigeration, also known as semiconductor refrigeration, uses the principle of the Peltier effect to achieve refrigeration. For example, Chinese Patent Document No. CN2051727 disclosed a high-efficiency electronic refrigerator on January 24, 1990. Its heat dissipation system is composed of a connected and sealed vacuum system consisting of an evaporator and a condenser; The device is composed of a vacuum-tight container filled with working fluid; the connection between the semiconductor refrigeration stack, the heat-absorbing cold storage device and the evaporator 1 is to use a double-sided metallized ceramic plate as the intermediate body and adopt a welding process. Electronic refrigeration has the characteristics of simple structure, miniaturization, high reliability, and...
