Description

Fully sealed box temperature cooling device

technical field

The utility model relates to a temperature cooling device, in particular to a device capable of cooling the temperature in a fully sealed box equipped with high-voltage electronic and electrical equipment that is prone to heat generation.

Background technique

With the development of science and technology, the degree of intelligence is getting higher and higher, so a large number of indoor and outdoor fully sealed boxes are used. These fully sealed boxes are equipped with electronic and electrical equipment, including high-voltage and low-voltage. When it is easy to generate heat, if it works at too high a temperature, the electronic and electrical equipment will burn out. At the same time, if these electronic and electrical equipment are affected by moisture and dust in the air, short-circuit discharge will occur, which will also damage the equipment. Therefore, it is best to seal the electronic and electrical equipment with a fully sealed box, and it cannot be cooled by fan exhaust. Now the common cooling method of the fully sealed box is to pass several pipes in the fully sealed box to ventilate the pipes or pass cooling water or cooling oil to cool down. The cooling effect of this method is very unsatisfactory. Taking the fully sealed box of the switching power supply part and the magnetron part of the microwave sulfur lamp as an example, the patent No. "ZL200610045648.6" published in the Chinese Patent Gazette on July 18, 2007 is "an explosion-proof explosion-proof microwave Sulfur lamp", which is provided with a water pump connected to the condenser in the main cavity, and the water cooling tubes connected to the water pump are respectively wound on the magnetron, waveguide, transformer and motor. If this method wants to obtain a good cooling effect, it is necessary to increase the length of the water-cooled pipe and wind all the electronic and electrical equipment, which is very costly and increases the difficulty of installation and maintenance.

Contents of the invention

The purpose of this utility model is to provide a cooling device with good heat dissipation effect and low cost for the fully sealed box installed with high-voltage electronic and electrical equipment that is easy to generate heat, aiming at the defects and deficiencies of the above-mentioned prior art.

In order to achieve the above object, the technical solution adopted by the utility model is: the temperature cooling device in the fully sealed box includes a fully sealed box equipped with electronic and electrical equipment, and a sealed heat exchange box is installed outside the fully sealed box , a heat absorption channel and an air outlet channel are arranged between the fully sealed box and the heat exchange box, a fan is installed in the fully sealed box, the output air of the fan is opposite to the heat absorption channel, and a section of the heat pipe extends into the heat In the exchange box, the other section is located outside the heat exchange box;

Radiating fins are installed on the heat pipe wall outside the heat exchange box;

Heat-absorbing fins are installed on the wall of the heat pipe in the heat exchange box;

The surface of the heat-absorbing sheet is coated with a layer of heat-absorbing material.

The utility model transmits the heat generated by the electronic and electrical equipment in the fully sealed box to the heat exchange box through the fan and the heat absorbing channel, and then uses the heat absorbing sheet to absorb the heat and then uses the heat pipe to transfer the heat to the outside of the heat exchange box. The heat sink outside the fully sealed box dissipates heat. The flow of air in the fully sealed box can reduce the temperature synchronously, prolong the service life of the electronic and electrical equipment in the fully sealed box, and can avoid the influence of dust and moisture in the air on the electronic and electrical equipment. It has the characteristics of good cooling effect and low cost.

Detailed ways

As shown in Fig. 1 and Fig. 2, the utility model includes a fully sealed box 1 for installing electrical and electronic equipment and a sealed heat exchange box 2 installed outside the fully sealed box 1. A heat absorbing channel 8 and an air outlet channel 9 are arranged between the fully sealed box 1 and the heat exchange box 2 , and a fan 7 is installed in the fully sealed box 1 , and the output air of the fan 7 is opposite to the heat absorbing channel 8 . The greater the distance between the heat absorption channel 8 and the air outlet channel 9, the better, so that all the air in the fully sealed box 1 and the heat exchange box 2 can flow when the fan 7 works. A heat pipe 5 is installed on the heat exchange box 2 , and one section of the heat pipe 5 is located inside the heat exchange box 2 , and the other section is located outside the heat exchange box 2 . One or more heat pipes 5 can be provided according to heat dissipation requirements. Several heat-absorbing fins 3 are installed at intervals on the wall of the heat pipe 5 in the heat exchange case 2, and a layer of heat-absorbing material 4 is coated on the surface of the heat-absorbing sheet 3, so that the heat pipe 5 located in the heat exchange case 2 It is easier to absorb heat and send it out of the heat exchange box 2. Several cooling fins 6 are installed at intervals on the wall of the heat pipe 5 outside the heat exchange box 2 to increase the heat dissipation area.

The utility model turns on the fan 7 while the electronic and electrical equipment in the fully sealed box 1 is working, the heat generated by the electronic and electrical equipment is transferred to the heat exchange box 2 through the fan 7 and the heat absorption channel 8, and the heat exchange box 2 installed in the heat exchange box 2 The heat-absorbing fins 3 on the wall of the duct 5 absorb the heat and send it out of the heat exchange box 2 through the heat duct 5, where the heat is dissipated by the cooling fins, and the cooled air returns to the fully sealed box 1 through the air outlet channel 9 to achieve full sealing The temperature cooling effect of box 1.
