Semiconductor-refrigerated small-scale air-conditioner

Abstract

The invention relates to a semiconductor-refrigerated small-scale air-conditioner, which comprises a semiconductor refrigerating device with one or more cold surfaces and hot surfaces, wherein one or more radiating fins and a fan are arranged on each cold surface; the cold surface of the semiconductor refrigerating device is arranged in a cabinet which is required to be cooled; the radiating fins at the cold end of the semiconductor refrigerating device are arranged perpendicular to the ground, and are wrapped by a shell to form air outlets, a condensed water collecting opening and a support frame of the fan at the cold end; two groups of air ducts are externally connected to the two air outlets on upper and lower sides of the radiating fins, and one end of each air duct is connected with a flexible tube, so that condensed water is led out of the cabinet; the radiating fins at the cold end of the semiconductor-refrigerated air-conditioner are wrapped by two plastic parts to form the condensed water collecting opening, and have the effect of the support frame of the fan at the cold end; and the two air outlets at the cold end of the semiconductor-refrigerated air-conditioner are externally connected with the two groups of plastic air ducts to leave the distance between the air inlets and air outlets of the fan at the cold end of the air-conditioner fully, so that the temperature inside the cabinet is uniform fully.

Description

technical field [0001] The invention belongs to the field of electronic technology and relates to an air conditioner, in particular to a small air conditioner which uses a semiconductor refrigeration device to work. Background technique [0002] Such as Figure 1-5 As shown, there will be a hot surface 11 and a cold surface 12 when the semiconductor refrigeration device 1 is powered on. In order to make the semiconductor refrigeration device work normally, it is generally necessary to assemble a heat sink 111 and a fan 112 on its hot surface, so that Dissipate heat to the environment; when the semiconductor refrigeration device is used to cool the air, it is also necessary to install a heat sink 121 and a fan 122 on its cold surface to exchange heat with the air to cool the air. The semiconductor refrigeration air conditioner is used to control the temperature inside a cabinet 2, which can be a communication switch cabinet or other industrial cabinets (with a large number of...

[0005] (2) The temperature inside the cabinet is uneven

[0006] (3) Due to size limitations, the fans used in semiconductor refrigeration air conditioners are generally 92X92MM or 120X120MM. Due to the small air volume, they can only effectively adjust the temperature in a local area of ​​the cabinet.
