Abstract
The utility model relates to an electric insulated heat pipe. The electric insulated heat pipe is additionally provided with an insulated sealing gasket between a heating end and a heat dissipating end. The inner of the pipe is provided with media with good insulated performance and good heat conducting performance, and the media can compact the pipe wall. The heat dissipating end of the electric insulated heat pipe has no electricity. Therefore, the safe and normal work of the electronic components can be guaranteed. Meanwhile, the electric insulated heat pipe has good pressure resistance performance and high power capacity for heat conduction. The utility model can be easily cleaned and repaired without cutting off electricity, and therefore, the producing efficiency can be enhanced. The requirements of pressure resistance and heat dissipation of the electronic components with various power capacities can be achieved by changing the materials of the pipe wall, dimension of the pipe wall, and the media in the pipe.
Description
The utility model relates to a kind of heat exchanger that middle heat transfer medium is arranged, particularly a kind of electric insulation heat pipe.
A kind of semiconductor heat-pipe radiator is disclosed in the clear 60-57956 patent document of day disclosure special permission communique, there is not insulating barrier between its fire end and the radiating end, just when heat pipe uses side by side, between the groups of fins of every heat pipe electrical insulating board is installed, working medium is made in dress water or fluorine Lyons in the pipe.The weak point of this heat pipe is: the radiating end of heat pipe is charged, thereby drops on dust on the fin or humid air and be easy to cause between each fin and electric conduction phenomena occurs, thereby influences the silicon controlled operate as normal, and is very dangerous.On the other hand,, must have a power failure when maintenance or cleaning, bring enormous economic loss to production because whole heat pipe is charged.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of electric insulation heat pipe is provided.
The purpose of this utility model can reach by following measure, the electric insulation seal washer of hear resistance and good airproof performance is installed so that the radiating end of heat pipe is not charged between the fire end of heat pipe and radiating end.Also to can adopt bolt to connect fire end and firm the linking together of radiating end simultaneously, also can adopt connected modes such as adhesive by flange.Be equipped with in the pipe that electrical insulating property is good, good thermal conduction and the non-electrolyte compatible with tube wall make working medium, thereby guarantee that the radiating end of heat pipe is not charged and good thermolysis arranged.
The insulated enclosure packing ring can adopt the material of hear resistance, sealing and good insulating such as engineering plastics such as nylon, polytetrafluoroethylene (PTFE) or rubber to make.
Intraductal working medium can adopt alcohol or electrical insulating properties such as carbon tetrachloride or acetone or methyl alcohol are good, good thermal conduction and the non-electrolyte compatible with tube wall.
At the radiating end of heat pipe a plurality of fin perpendicular with heat pipe can be installed, and can adopt water-cooled, air-cooled or other types of cooling.
Fig. 1 is an electric insulation heat pipe structure schematic diagram, and 1. is fire end among the figure; 2. be the insulated enclosure packing ring; 3. be flange; 4. be binder bolt; 5. be radiating end; 6. be fin.
Fig. 2 uses schematic diagram for the electric insulation heat pipe on electronic devices and components.7. is radiating block among the figure; 8. be electronic devices and components.The electric insulation heat pipe can severally side by side use together according to producing needs.During use, the radiating block that makes with the reasonable material of heat dispersion clamps electronic devices and components, and the fire end of every heat pipe inserts in the radiating block.Connect power supply, the heat that produces during electronic devices and components work imports the fire end of heat pipe into by radiating block, the steam that working medium boiling in the heat pipe produces rises to radiating end, meet that to condense into liquid after cold again dirty, pass through the evaporation of working medium and the heat radiation of condensation and tube wall like this, thereby guarantee the operate as normal of electronic devices and components.
The utility model has been owing to added the electric insulation seal washer between fire end and radiating end, thereby makes the radiating end of heat pipe not charged.When electronic devices and components are worked, be unlikely to influence because of the accumulation of dust and humid air and make between the fin and conduct electricity, the also unlikely electronic devices and components that make puncture.Need not have a power failure simultaneously and just can clean very easily and keep in repair.Not only owing to adopted alcohol or electrical insulating properties such as carbon tetrachloride or acetone or methyl alcohol are good, good thermal conduction but also the non-electrolyte compatible with tube wall are made working medium, thereby the breakdown voltage of heat pipe and heat transfer power are greatly enhanced.
This electric insulation heat pipe makes as the material that can adopt good thermal conductions such as copper, aluminium, steel by the material of change tube wall, changes size, the length size of caliber, and the working medium of adorning in the pipe, just can reach the requirement that various electronic components of high power are withstand voltage and dispel the heat.
Embodiment 1
Fig. 1 shows a most preferred embodiment of the present utility model.It is the copper tube of 25mm that tube wall adopts external diameter, and the thick teflon insulation seal washer of 10mm is installed between fire end and the radiating end, and fire end and radiating end is coupled together by flange with bolt.Heating segment length 130mm, heat radiation segment length 250mm, intraductal working medium is a chemical pure alcohol, loading is 1/3rd of a bringing-up section volume.The type of cooling is a water-cooled.Through testing the withstand voltage 7000V of reaching heat transfer power is 300 watts.
Claims (3)
1, a kind of electric insulation heat pipe, constitute by fire end and radiating end, water is housed in the pipe or working medium is made in fluorine Lyons, it is characterized in that: hear resistance and the good electric insulation seal washer of sealing are installed between fire end and radiating end, and with fire end and firm the linking together of radiating end, be equipped with in the pipe that electrical insulating property is good, good thermal conduction and the working medium compatible with tube wall.
2, according to the said electric insulation heat pipe of claim 1, it is characterized in that: the insulated enclosure packing ring can adopt the material of hear resistance, sealing and good insulating such as engineering plastics such as nylon, polytetrafluoroethylene (PTFE) or rubber.
