Each intensive high-power semiconductor temperature adjusting block module and each external circulation miniaturized finned grid tube group phase change radiator are connected through two heat pipes to form a closed internal circulation loop, an internal circulation heat dissipation fan is arranged on an internal circulation heat dissipation piece and conducts forced heat dissipation on the internal circulation heat dissipation piece in a forced air exhaust mode, and the internal circulation heat dissipation piece is in seamless fit with the internal circulation surface of the intensive high-power semiconductor temperature adjusting block module. Each phase-change heat-exchange temperature-equalizing plate is seamlessly attached to the outer circulation surface of each intensive high-power semiconductor temperature adjusting block module, and a composite phase-change working medium synthesized by inorganic hydrated salt materials is filled in each phase-change heat-exchange temperature-equalizing plate. The phase-change heat exchange temperature equalizing plate is a copper direct conduction absorption type sealed box body type structure, and a composite phase-change working medium synthesized by inorganic hydrated salt materials is filled in the sealed box body type structure and used for quickly absorbing a high-heat-flow-density heat source released by the intensive high-power semiconductor temperature adjusting block module. The external circulation miniaturized finned grid tube group phase-change radiator comprises a forced air-cooling fin group and a phase-change grid tube group, wherein a composite phase-change working medium synthesized by an inorganic hydrated salt material is filled in the phase-change grid tube group, and the phase-change grid tube group is transversely inserted into the forced air-cooling fin group and is in close contact with fins of the forced air-cooling fin group to form the external circulation miniaturized finned grid tube group phase-change radiator. And the external circulation radiator fan performs forced heat dissipation on the forced air cooling fin group and the phase change grid tube group in an air cooling mode. Liquid-vapor phase change working media are filled in the heat pipes, the heat pipes penetrate through the interior of the phase-change heat exchange temperature equalizing plate and are connected with the phase-change radiators of the external circulation miniaturization finned grid pipe group, and the heat pipes are transversely inserted into the forced air cooling fin group and are in close contact with fins of the forced air cooling fin group, so that the external circulation miniaturization distributed phase-change circulation efficient heat dissipation system is formed.

This intelligence temperature regulation system's inside and outside circulation system all adopts the forced air cooling structure to reach water-cooling radiating effect, can effectively with the heat in the cabinet and moisture transfer outside the cabinet, guaranteed the interior power equipment steady operation of cabinet. After a period of time of practical use, we find that although this system leakproofness is better and possess certain interior dustproof function of cabinet, because whole equipment is installed in the abominable open air of environment or field usage usually, and be provided with a plurality of circulation business turn over wind mouths (only do protection against rodents, no filtering effect), leaf, weeds, dust, granule and piece such as grit get into intelligent temperature regulation system and cabinet internal portion very easily from this during construction or wind-blowing, especially the extrinsic cycle air intake is the most serious, probably block up the inside and outside heat exchange of influence switch board under the extreme condition, intelligent temperature regulation system's life has not only been shortened, and lead to the inside radiating effect of switch board to descend by a wide margin, there is great potential safety hazard.

Detailed Description

In order to make those skilled in the art fully understand the technical solutions and advantages of the present invention, the following embodiments are further described.

The intelligent temperature regulating system of the power transformation cabinet shown in fig. 1-4 comprises an internal circulation mode and an external circulation mode. After external cold air is sucked from an external circulation air inlet D by an external circulation radiator fan, forced heat dissipation is carried out on a forced air cooling fin group and a phase change grating tube group, solid particles are sucked along with the air in the process, the solid particles flow and accumulate among all devices such as the forced air cooling fin group and the phase change grating tube group and in the cabinet body, and the ventilation and heat exchange are not smooth after the forced air cooling fin group and the phase change grating tube group are used for a long time, so that the insulation performance and the heat dissipation performance of the devices are poor, the devices cannot operate stably, and the reliability is reduced.

To this end we have developed a set of filter assembly fittings as shown in figures 5-8. The device comprises a plurality of cubic filter plates which are divided into a front surface and a back surface, wherein one surface which is opposite to the cabinet body is defined as the back surface, and the opposite other surface (facing the outside) is defined as the front surface. The front side of the filter plate is provided with a filter screen 1 occupying most area, the upper edge, the lower edge, the left edge and the right edge of the back side of the filter plate are selectively embedded with a magnet block 2, and the magnet block 2 and the metal plate are fixed together under the magnetic attraction effect. Solid impurity particles in the outside air are filtered by the filter screen 1, the obtained clean air completes heat exchange through the external circulation air inlet D, and weeds, leaves, gravels and the like are blocked outside the system and the cabinet body.

Considering that the number of the external circulation air inlets D is not fixed in practical application (6 are arranged in the upper and lower rows in fig. 3), the filter plates are designed to be a single body which can be connected with each other in order to adapt to various installation environments. The main dependence for realizing the effect is the step on the back of the upper end of the filter plate, the connecting column 3 positioned on the step, the step on the front of the lower end of the filter plate and the connecting hole 4 positioned on the step. The connection mode of two adjacent filter plates is shown in figure 8, the step at the lower end of the last filter plate and the connecting hole 4 on the step are just matched with the step at the upper end of the next filter plate and the connecting column 3 on the step, and the connecting column 3 is inserted into the connecting hole 4 to fixedly connect the two filter plates together. Other filter plates are mutually connected together in the same way, and finally fixed on the metal panel by magnetic attraction.

Considering that the air passing through the internal circulation air inlet and outlet (A and B) and the external circulation air inlet and outlet (C and D) has different degrees of cleanness and greatly different contents of solid particle impurities, the filter element 5 (shown in figure 7) is additionally arranged on the filter plate of the external circulation air inlet and outlet to further enhance the filtering effect. The filter element 5 can be made of the same or similar material as the filter element of the automobile air conditioner or the filter element of the household air purifier.

The transformer substation control cabinet provided with the matched filtering equipment can ensure that each external circulation device and the interior of the cabinet are in a clean state only by overhauling and cleaning the lower filter screen 1 and the filter element 5 at intervals of 3-6 months (depending on the external environment). Even if the whole system is installed and operated for months, the temperature adjusting effect (heat dissipation and refrigeration) in the cabinet is still good as before, and better economic benefit is obtained.
