Description
Technical field
The utility model is mainly applied to track traffic industry, and what relate to is a kind of natural heat dissipation device of heavy-duty diode.
Background technology
At present general heavy-duty diode adopts forced air cooling or liquid cools, but the range of application of this two schemes is narrower, and especially in strenuous vibration and impact, and exist in surrounding medium in the adverse circumstances such as damp and hot, dust, equipment dependability can decline to a great extent.And track traffic industry, this equipment is generally applied in the equipment of car body, there is larger jerk, environment is damp and hot, and track exists throughout the year more metallic dust, when equipment protection not at that time, the reliability of diode significantly reduces, and may cause equipment fault.
Utility model content
Problem to be solved in the utility model: for forced air cooling and the low reliability of heavy-duty diode heat abstractor of liquid cools, the characteristic of maintainability difference, the utility model provides and a kind ofly adopts that structure is simple, cost is low and the natural heat dissipation device of good heat dissipation effect, and significantly improves equipment dependability.
Technical scheme: the natural heat dissipation device providing a kind of heavy-duty diode in order to overcome the above problems the utility model, is characterized in that: comprise radiator, heat pipe, insulating heat-conductive film, cushion block, upper busbar, lower busbar, insulation board, pressing plate, diode; Diode is arranged between busbar and lower busbar and forms diode assembly, and this diode assembly is placed on cushion block, compresses insulating heat-conductive film between cushion block and the radiator being inlaid with heat pipe.
Diode is fixed between upper busbar and lower busbar by little nylon column and stove bolt sub-assembly.
Lower busbar is successively pressed with insulation board and pressing plate, and diode assembly is compressed on a heat sink by insulation board, pressing plate and large nylon column, king-bolt sub-assembly.
Radiator material aluminium alloy 6061.
Between insulating heat-conductive film and the contact-making surface of cushion block, between radiator and the contact-making surface of insulating heat-conductive film, be all coated with heat-conducting silicone grease.
Beneficial effect: radiator material aluminium alloy 6061 of the present utility model, and in radiator base plate, inlay many heat pipes, reduce thermal resistance.All uniformly smear heat-conducting silicone grease with radiator, cushion block face between contacting at insulating heat-conductive film, while reduction thermal resistance, realize insulation.The utility model utilizes the combination of common sheet aluminum profile heat radiator and heat pipe, insulating heat-conductive film, realize naturally cooling of heavy-duty diode, reduce temperature rise, solve the problem that heavy-duty diode under some particular surroundingss is inconvenient to adopt forced air cooling and liquid cools.This heat abstractor is installed simple, easily changes, and heat transfer rate is fast, and lightweight, fail safe is high, reliability high.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, further detailed description is done to the present invention.
As shown in Figure 1, the utility model provides a kind of natural heat dissipation device of heavy-duty diode, comprises radiator 1, heat pipe 2, insulating heat-conductive film 3, cushion block 4, upper busbar 5, lower busbar 6, insulation board 7, pressing plate 8, little nylon column 9, large nylon column 10, stove bolt sub-assembly 11, king-bolt sub-assembly 12, diode 13; Diode 13 is fixed between upper busbar 5 and lower busbar 6 by little nylon column 9 and stove bolt sub-assembly 11, forms diode assembly; This diode assembly is placed on cushion block 4, compresses insulating heat-conductive film 3 between cushion block 4 and the radiator 1 being inlaid with heat pipe 2; Diode assembly is compressed on a heat sink by insulation board 7 and pressing plate 8 by large nylon column 10 and king-bolt sub-assembly 12.
This device operation principle is: the heat of diode 13 conducts on heat-pipe radiator by busbar 5 and cushion block 4, heat is shed by the radiation of aluminum fin-stock and convection current by radiator 1, and insulating heat-conductive film 3 to achieve radiator not charged, meet insulating requirements, namely realize heavy-duty diode natural heat dissipation.
The foregoing is only the preferred embodiments of the present invention, be not restricted to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present invention.
