Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the present invention are described further.
The specific embodiment of the heat transfer system of the gas tank of the present invention, as shown in Figure 1 to Figure 3, wherein, 1 is heat pipe, and 2 for inhaling
Hot device, 3 is fixed block, and 4 for sealing aluminium sheet, and 5 is radiator.
The hot junction that left end is heat pipe of diagram heat pipe 1, hot junction is provided with heat extractor 2, and the other end is the cold end of heat pipe.Use
Time, on the premise of meeting insulation distance, heat extractor 2 electrical equipment in gas insulation switch cabinet gas tank as far as possible,
Make the heat absorption that electrical equipment can quickly be produced by heat extractor 2, the fewest being discharged into of heat of electrical equipment release
In gas tank.Multiple heat transfer sheet is installed on heat extractor 2, when heat transfer sheet is installed, adjusts the position of heat transfer sheet, make the placement of heat transfer sheet
Direction is consistent with air current flow direction near electrical equipment, makes heat extractor 2 more efficiently absorb heat from neighbouring high-temperature gas
Amount.Heat extractor 2 can be that interference fit is connected or uses pressing plate and consolidates by structures such as screws with the connected mode in the hot junction of heat pipe 1
Fixed connection.It can be that interference fit is connected with the connected mode of fixed block 3 that the other end connection of heat pipe 1 has fixed block 3, heat pipe 1
Or using pressing plate to be fixed on fixed block 3 by heat pipe 1, fixed block 3 connected mode such as is connected by screw and is fixed on sealing aluminium sheet 4
On.As can be seen from Figure, the cold end of heat pipe 1 is higher than hot junction, can make the heat-conducting medium in heat pipe in use after condensation
Quickly return to hot junction.During use, the shape of heat pipe cold end, cold end and the contact area sealing aluminium sheet 4 are entered according to practical situation
Row sum-equal matrix, as by the upwards bending of heat pipe cold end, makes heat pipe cold end and the contact area sealing aluminium sheet 4 increases to improve heat transfer effect
Rate.
