Air cooling and liquid cooling dual-purpose heat radiator

Abstract

The invention provides an air cooling and liquid cooling dual-purpose heat radiator, which consists of a bottom plate, a heat pipe, a liquid cooling plate, a liquid cooling upper cover, a heat radiation fin and a fan, wherein the heat pipe is bent and folded into a U shape, the horizontal part of the middle section of the heat pipe is welded in a hole commonly preserved by the bottom plate and the liquid cooling plate, and the vertical parts at the two sides of the heat pipe are welded with the heat radiation fin. The bottom plate is in contact with a heat source. During the air cooling, the fan is started, and the heat is transmitted into the atmosphere through the bottom plate along the heat pipe from the heat radiation fin. During the liquid cooling switching, the fan is switched, the cooling liquid is introduced into the liquid cooling upper cover, the heat is transmitted ot the liquid cooling plate through the bottom plate and the heat pipe, and the heat is brought away by cooling liquid flowing through the liquid cooling plate. The air cooling and liquid cooling dual-purpose heat radiator has the advantages that the two heat radiation modes including the air cooling mode and the liquid cooling mode can be conveniently switched according to the concrete use requirements, the switching process is simple, the operation is convenient, the part dismounting is not needed, in addition, both the air cooling heat radiation efficiency and the liquid cooling heat radiation efficiency can be ensured, and the air cooling and liquid cooling dual-purpose heat radiator is suitable for being used as a heat sink for a thermoelectric refrigerating unit.

Description

technical field [0001] The invention relates to an air-cooled and liquid-cooled dual-purpose radiator, which is suitable for heat dissipation of thermoelectric refrigerators. Background technique [0002] Thermoelectric coolers are small coolers based on the Peltier effect. They have the advantages of small size, high reliability, and ease of use. They are widely used in high-sensitivity cameras and some other imaging devices. The cooling temperature of the thermoelectric cooler is related to the temperature of its hot end, the lower the temperature of the hot end of the thermoelectric cooler, the lower the cooling temperature. In contrast, the hot end temperature of a thermoelectric cooler is determined by the heat sink used. [0003] The radiators currently used can be divided into two categories according to the heat dissipation method: air cooling and liquid cooling. Air-cooled radiators are simple to use and require no special accessories for use. However, the heat d...

Problems solved by technology

However, the heat dissipation effect is affected by the ambient temperature. When the ambient temperature is too high, the heat dissipation effect is not good

The liquid-cooled radiator has good heat dissipation effect and is less affected by the ambient temperature, but it needs to connect the pipeline for conveying the coolant and the equipment for supplying the coolant, which is easily restricted by the equipment
