Abstract
The invention discloses a method for dissipating heat of a heat pipe for an explosion-proof electric apparatus, and relates to the technical field of coal mine safety and power electronics. The design scheme is as follows: a heating electronic element is arranged on a metal heat-collecting substrate which is welded on an inner wall of an explosion-proof cavity body. A row of uniformly distributed blind holes in parallel to the substrate are processed on one lateral face of the metal heat-collecting substrate and well matched with a heat absorbing end of a heat pipe radiator. Lateral faces of openings of the blind holes on the metal heat-collecting substrate seal a matched opening on the wall of the explosion-proof cavity from an inner side of the explosion-proof cavity, the openings of the blind holes are formed outside the explosion-proof cavity body, firm welding and sealing are achieved, and requirement of explosion-proof technology is met. When the heat pipe radiator is installed, the heat absorbing end of the heat pipe radiator is inserted into the blind holes, and then necessary fastening and protecting measures are performed.
Description
Technical field
The present invention is a kind of method for dissipating heat of thermotube that is used for explosion-proof electric apparatus, relates to safety of coal mines and electric and electronic technical field.
Technical background
Being flooded with inflammable and explosive media such as gas, coal dust in the coal mining production process in the mine, is the major hidden danger of miner's personal safety and production safety.For this reason, antiknock device and technical measures are extensively adopted in the coal mine, to ensure the safety of life and property of bargh.Yet one of common trait of equipment explosion-proof technology measure is airtight isolation, causes very big difficulty for the heat radiation of some high-power electric energy conversion equipments.The security of operation and the useful life of equipment have been influenced.For this reason, we have designed a kind of new heat-pipe radiator that utilizes and have given the method for explosion-proof electric apparatus internal heat dissipating cooling.
Technical scheme
The invention discloses a kind of method for dissipating heat of thermotube that is used for explosion-proof electric apparatus.
The method for dissipating heat of thermotube of this explosion-proof electric apparatus is the heat pipe heat radiation technology of successful implementation in conventional environment, is implanted on the explosion-proof electric apparatus, overcomes the unfavorable problem of heat radiation that explosion precaution brings.
This there are a lot of units carried out successfully attempting, have realized good technical effect.For example: No. 01245013 utility model patent disclosed " the flame proof heat-pipe radiating apparatus of mine-used frequency-converter "; 03212986.6 number utility model patent disclosed " flame-proof type heat-pipe radiator " all is good scheme.In view of above-mentioned two kinds of schemes, heat sink arrangement is an individual components, all is with the flame proof ring flange heat abstractor to be installed on the explosion-proof cavity.In the repair demolition process, exist to damage explosion suppresion surface, the hidden danger that causes propagation of explosion such as improper is installed.We have designed a kind of new method that does not have this respect hidden danger.
Design of the present invention is: heat-generating electronic elements is installed on the collector metal substrate on the inwall that is welded on explosion-proof cavity.Process a row even cloth blind hole parallel with base plan on the side of collector metal substrate, the heat absorbing end of this blind hole and heat-pipe radiator is good fit.The opening part that the blind hole open side of collector metal substrate is mated at the explosion-proof chamber wall from the inboard shutoff of explosion-proof chamber, blind hole is opened on outside the wall of explosion-proof cavity, and the firm welding sealing reaches the explosion-proof technology requirement.When heat-pipe radiator is installed,, is aided with necessary fastening protection again and gets final product as long as the heat absorbing end of heat-pipe radiator is inserted in the blind hole.It is characterized in that: process a row even cloth blind hole parallel on the side of collector metal substrate with base plan, the opening part that the blind hole open side of collector metal substrate is mated at the explosion-proof chamber wall from the inboard shutoff of explosion-proof chamber, blind hole is opened on outside the wall of explosion-proof cavity, the firm welding sealing reaches the explosion-proof technology requirement.When heat-pipe radiator is installed, the heat absorbing end of heat-pipe radiator is inserted in the blind hole.
This scheme, radiator structure do not have propagation of explosion hidden danger, and be simple in structure, and the heat-pipe radiator simple installation is implemented easily.
Embodiment
Below, utilize an embodiment of type that implementation method is described with the present invention.One embodiment of the present of invention are the application on the flame-proof type charger of this technology.Implementation method as shown in Figure 1.
Description of drawings
Fig. 1 is an embodiment of the invention schematic diagram.Wherein: 1, flame-proof type cavity; 2, collector metal substrate; 3, heat-pipe radiator; 4, protective cover; 5, thyristor rectifier module; 6, rectifier transformer.
