Description
Technical field
The utility model relates to a kind of heat-pipe radiator that can be used for the city rail locomotive.This radiator is used for distributing the locomotive power semiconductor device owing to the heat that dissipation power produces, and belongs to the heat dissipation technology field of semiconductor device.
Background technology
Along with development of Urban Traffic, subway and light rail have obtained unprecedented attention and development, develop the today of advancing by leaps and bounds in power electronic technology and automatic control technology, the control loop major loop of rail locomotive all adopts the high-power electric semiconductor device, no matter be rectifying tube and thyristor controllable silicon, still devices such as GTO and IGBT, working under big electric current all can produce huge heat and make these semiconductor device out of control or damage.Good heat dissipation equipment or device are the necessary conditions of these semiconductor device operate as normal.Heat abstractor commonly used at present has cast aluminium radiator, aluminium section bar radiator etc., and their shortcoming is that radiating efficiency is low, thermal resistance is big, weight is big, and certain heat radiation limit is arranged; Another kind is a water-filled radiator, and its thermal resistance small size is little, in light weight, but needs the recirculated water cooling, is not suitable for using on the locomotive that moves.Chinese patent ZL98231416.7 discloses a kind of heat-pipe radiator, is called as the superconductor of heat, and its thermal resistance is more much smaller than solid radiator, the radiating efficiency height.The busbar of large power heat pipe radiator screws down with the heat absorption pedestal of radiator usually and is connected, but this structure contact heat resistance is big, can produce additional heat when big electric current moves.
The utility model content
The purpose of this utility model is the shortcoming at heat-pipe radiator in the prior art, design a kind of heat-pipe radiator of track traffic special use, overcome the big problem of contact heat resistance that each contact-making surface of heat-pipe radiator causes, further reduce thermal resistance, improve the radiating efficiency of radiator.
The heat-pipe radiator of the utility model design comprises heated substrate, busbar, heat pipe and radiating fin; Need the heater element of heat radiation to place between two heated substrate, two heated substrate respectively with two busbar relative fixed; The one end while of heat pipe and the end relative fixed of heat conduction substrate and busbar, radiating fin is fixed on the heat pipe, is separated with the insulation division board between two row's radiating fins; Busbar, insulation board and heat pipe are fixed on the frame by insulating support.
The heat-pipe radiator of the utility model design is compared with existing heat-pipe radiator, and its difference is: 1, heat pipe seals difference, and what prior art adopted is a conical plug, and what the utility model adopted is sealing by fusing airtight vacuum structure.2, heat pipe and the pedestal that is heated is connected the method that adopts the scolding tin sealing by fusing; Heat-exchange working medium is in heat pipe, and heat pipe is a capillary structure.And the working medium liquid of Chinese patent ZL98231416.7 is in heat-conducting block, and heat pipe is non-capillary structure.3, heat radiating fin structure difference.4, fin is different with the method for attachment of heat pipe.The advantage of the heat-pipe radiator of the utility model design is easy to manufacture, and radiating effect is good.
Description of drawings
The top view of the radiating tube that Fig. 1 designs for the utility model.
Fig. 2 is the shape schematic diagram of insulation board in the heat-pipe radiator.
1 is the pedestal that is heated among Fig. 1, and 2 is heat pipe, and 3 is radiating fin, and its end is a rugosity, to increase area of dissipation, 4 insulating supports, 6 insulation division boards for the epoxy insulating board composition for the epoxy insulating board composition, 7 is busbar, and 8 for needing the element of heat radiation, and 9 is frame.Fig. 2 is the shape of insulation board in the heat-pipe radiator, and insulation board is the kitchen knife shape, and wherein the hilt part A is covered above heater element, and cutter hub part B is every between two row's radiating fins.
Embodiment
As shown in Figure 1, the heat-pipe radiator of the utility model design comprises heated substrate 1, busbar 7, heat pipe 2 and radiating fin 3.Need the heater element 8 of heat radiation to place between two heated substrate 1, two heated substrate respectively with two busbar 7 relative fixed.The one end while of heat pipe 2 and the end relative fixed of heat conduction substrate 1 and busbar 7, radiating fin 3 is fixed on the heat pipe 2, is separated with insulation division board 6 between two row's radiating fins; Busbar 7, insulation division board 6 and heat pipe 2 are fixed on the frame 9 by insulating support 4.
The heat-pipe radiator of the utility model design, can be exclusively used in rail locomotive, because the rail locomotive operating voltage is higher, so this radiator is fixed on the shelf of being made up of epoxy insulating board 4, for preventing that electric discharge phenomena take place between the fin, between two groups of fin, isolate with a kitchen knife shape epoxy insulating board 6 as shown in Figure 2.
The pedestal that is heated also is an electrode, and its busbar 7 is made one with pedestal, has reduced the contact heat resistance of busbar and pedestal like this, has reduced the additional caloric value when big electric current moves.Busbar and pedestal can adopt forging forming one time, also can adopt welding procedure to finish.
The level of intimate that heat pipe 2 is connected with the pedestal 1 that is heated has influence on the contact heat resistance between them, has influence on the transmission of heat, and the utility model adopts the method for scolding tin sealing by fusing to solve.
Heat pipe 2 can not leak because of the time for irritating the sealing by fusing airtight vacuum structure that heat exchange working medium is arranged; Because its inner capillary structure, this heat pipe slopes under the situation near level and uses.
