The inner electronic device radiator in an explosion-proof casing is characterized in that a heat pipe (7) is taken as a radiator in an explosion-proof casing (1), and nonmetallic electric insulation heat conducting material slices (4) and metallic material blocks (5) sintered as an entity are made into connecting pieces without electricity to connect with an electronic device (2) and the heat pipe (7). The heat pipe (7) has no electricity when the heat generated by the electronic device (2) in the explosion-proof casing (1) is transferred to outside world. The aims of lowering temperature in the explosion-proof casing (1) and preventing explosion caused by electrical spark generated by the radiator with electricity.
Description
The utility model belongs to electronic device, and especially high-power electronic device places the heat abstractor in the explosion-resistant enclosure.
The heat abstractor of existing electronic device, especially high-power electronic device is that a thyristor is directly contacted with one or one pair of radiator.The equivalent heat of the reactive loss of electronic device will be passed to radiator with heat in the unstable conduction mode, radiator again with this heat with free convection or forced convertion mode towards periphery environment distribute.Because radiator directly contacts with electronic device, cause on the radiator integral all chargedly, this is breakneck for the electronic-device radiator of working under inflammable and explosive environment.Must increase explosion-resistant enclosure for this reason.Be added with the electronic device of explosion-resistant enclosure, not only require its working temperature to be lower than a certain allowable temperature, and require radiator itself not charged,, set off an explosion in order to avoid produce electric spark.Owing to this reason, existing electronic-device radiator can not be applicable to the heat radiation of explosion-resistant enclosure internal electronic device.
The purpose of this utility model is to provide a kind of explosion-resistant enclosure internal electronic device, especially high-power electronic device heat abstractor of can be used for, effectively reduce the explosion-resistant enclosure internal temperature to below a certain allowable temperature to satisfy, and the uncharged requirement of heat abstractor itself.
For this reason, solution of the present utility model is: adopt the heat pipe that has certain distance between endotherm section and heat release section, nonmetal electric-insulation heat-conduction material and metal material are sintered to one, make respectively and electronic device and the contacted not charged connector of heat pipe; The heat that electronic device produces is passed to connector with heat-conducting mode, connector is passed to heat pipe with heat again, by medium in the heat pipe with the phase-change heat transfer mode partly heat spread out of in the explosion-resistant enclosure and pass to surrounding environment again, reduce temperature and the uncharged purpose of heat pipe in the explosion-resistant enclosure thereby reach.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is the utility model structural representation.
Fig. 2 is an A-A generalized section among Fig. 1.
Fig. 3 is a B-B generalized section among Fig. 1.
As seen from Figure 1, the utility model mainly by the electronic device that is positioned at explosion-resistant enclosure (1) (2), respectively with electronic device (2) and the contacted lead-in wire of nonmetal electric-insulation heat-conduction material piece (4) (3); The block of metallic material (5) that is sintered into one with a plurality of nonmetal electric-insulation heat-conduction material piece (4), be set in that the explosion-proof metallic sheath (6) of explosion-resistant enclosure (1) one side and evaporation section pass explosion-proof metallic sheath (6) and the heat pipe (7) that screws in the block of metallic material (5) is formed, the evaporation section of heat pipe (7) contacts with block of metallic material (5), and metallic sheath (6) is passed in the adiabatic section and condensation segment is made up of how secondary fin and place environment.
When electronic device is worked, will produce the heat of a large amount of reactive loss, the connector that these heats are formed through lead-in wire (3), nonmetal electric-insulation heat-conduction material piece (4), block of metallic material (5) is passed to the evaporation section of heat pipe (7) with heat-conducting mode; The heat absorption evaporation of heat pipe medium through being cooled to liquid in explosion-resistant enclosure (1) condensed exterior section behind the adiabatic section, and is dispelled the heat to the external world by fin.For satisfying requirement of explosion proof, explosion-proof faying face is formed by the explosion--proof regulations requirement in the metallic sheath (6) and heat pipe (7) adiabatic section that are set on the explosion-resistant enclosure.The entire heat dissipation device is fixed on explosion-resistant enclosure (1) inner surface with support (9), so that when work is stable; In addition, heat pipe (7) and block of metallic material (5) all have screw thread, and heat pipe (7) can pass metallic sheath (6) and screw in, screws out block of metallic material (5).
Fig. 2, Fig. 3 show heat pipe (7) when horizontal level is worked inner structure form and electronic device (2), the lead-in wire (3), nonmetal electric-insulation heat-conduction material piece (4), block of metallic material (5) and heat pipe (7) evaporation section between the contact situation.
For the heat pipe (7) of horizontal operation, one deck capillary wick (10) will be with in its inside; And the heat pipe (7) of vertical work then can be made into the gravity assisted heat pipe of not being with capillary wick.
Convenient for the installation and the replacing that make electronic device, the top cover of explosion-resistant enclosure (1) is made openable.
Most preferred embodiment of the present utility model is on metal copper billet (5) the side perisporium that a long * wide * height is 280 * 110 * 48mm, 6 block lengths on the equidistant sintering symmetrically * wide * thick are: the nonmetal electric-insulation heat-conduction material piece of the beryllium oxide of 81 * 81 * 1mm (BeO) (4), and by length * wide * thick be: the lead-in wire of 60 * 60 * 12mm (3) is passed to the nonmetal electric-insulation heat-conduction sheet of BeO (4) with the reactive loss heat of electronic device, metal copper billet (5) inner surface and heat pipe (7) evaporation section size are: M39 * 2, long 300mm; Condensation segment length 300mm, and 30 120 * 120mm fins are arranged.Heat pipe (7) medium is---acetone.In ambient temperature is 31 ℃, and the electronic device operating current is 220A, and the work of switching on continuously is in the time of 80 minutes, and lead-in wire (3) temperature is 80 ℃, and heat pipe (7) condensation segment temperature is 54 ℃, and temperature is 40 ℃ in the explosion-resistant enclosure.
The utility model has the advantage of: thermal source and low-temperature receiver apart from each other, be convenient to high-power electronic device (2) reactive loss heat is reached explosion-resistant enclosure (1) outside; Heat pipe (7) itself as radiator is not charged; And the little heat-transfer capability of thermal resistance is big, compact conformation, can dispel the heat to single or multiple high-power electronic devices simultaneously, is a kind of more new reasonable heat abstractor.
