Abstract
The utility model relates to a heat pipe radiator with a radiating fin space of 8-18 mm for cooling power electronic devices, comprising a heat body, a radiating fin, a heat pipe, the space between adjacent the radiating fins is 8-18 mm, an insulation ring for preventing the radiating fin from loosing is arranged between adjacent radiating fins. Positioning size of a punch of the radiating fin increases from an end of the heat body to a far end, an upper surface and a lower surface of the radiating fin are in horizontal state and in parallel. The utility model has the beneficial effects that, 1) the space of the radiating fin increases, causing air to flow fast, thereby fast bringing the heat away, greatly minishing thermal resistance, increasing heat emission effect; 2) the upper surface and the lower surface of the radiating fin are in the horizontal state, causing hot air to be vertical upwards, the thermal resistance is small and heat emission effect is good.
Description
Technical field
The utility model relates to the heat-pipe radiator that is used for the power electronic device cooling.
Background technology
The spacing of currently known heat-pipe radiator fin is less, and spacing is 8mm, and this radiator fin density is difficult for the circulation of air greatly, and heat can not be dispersed into rapidly in the air, has produced bigger thermal resistance, has influenced the radiating effect of radiator greatly.
Summary of the invention
The purpose of this utility model provides that a kind of thermal resistance is little, the inter fin space of good heat dissipation effect is the heat-pipe radiator of 8-18mm.
The technical solution of the utility model is described below:
Inter fin space is the heat-pipe radiator of 8-18mm, comprises heater, fin, heat pipe, and the spacing of adjacent fin is 8-18mm, is provided with the shading ring that prevents that fin is loosening between the adjacent fin.
The punching location dimension of described fin is increased to its far-end gradually by the heater end, and the upper and lower surface of fin is the level of state and be arranged in parallel.
Compared with prior art, the beneficial effects of the utility model are:
1) because the spacing of fin becomes big, can make air flows very fast, rapidly heat be taken away, reduce thermal resistance greatly, improve radiating effect.
2) because the upper and lower surface of fin is the level of state, so can make hot gas straight up, thermal resistance is little, good heat dissipation effect.
Description of drawings
Fig. 1 is that inter fin space is the structural representation of the heat-pipe radiator of 8-18mm.
Among the figure: 1-heater 2-fin 3-shading ring 4-heat pipe
Embodiment
See Fig. 1, inter fin space is the heat-pipe radiator of 8-18mm, comprises heater 1, fin 2, shading ring 3, heat pipe 4, and the spacing d of adjacent fin is 8-18mm, is provided with the shading ring 3 that prevents that fin is loosening between adjacent fin 2.
Heat pipe 4 is 5.75 ° of placements with horizontal direction, and the punching location dimension that is positioned at the fin 2 on the heat pipe 4 is increased to its far-end gradually by the heater end, and the upper and lower surface of fin 2 is the level of state and be arranged in parallel, and heater 1 is positioned at the lower end of heat pipe 4.
Following table is that inter fin space is the heat-pipe radiator of 8mm and the heat-pipe radiator data contrast table that inter fin space is 16mm, and all logical 400A electric current of the heater of two kinds of radiators is 40 minutes conduction time, and ambient temperature is 25 ℃.
