Abstract
The utility model relates to a CUP heat radiator, which consists of three parts: a fan, heat radiation fins and a heat absorbing bottom plate, wherein the fan is arranged on the top end of the heat radiation fins, the heat radiation fins are in radial distribution, the lower end of the heat radiation fins is connected with the heat absorbing bottom plate, the lower surface of the heat absorbing bottom plate is in tightly contact with a CPU, the thickness of the center part of the heat absorbing bottom plate is large, the edge part is thin, the side edges of the vertical cross section of the heat absorbing bottom plate are downwards inclined, and in addition, the side edges can be inclined along straight lines, and can also be inclined along arcs. When the heat absorbing bottom plate absorbs the heat generated by the CPU, the heat can be easily transmitted to the edge parts and the heat radiation fins arranged above the heat absorbing bottom plate, so the temperature distribution of the heat radiator is uniform, and at the same time, the weight of the heat radiator is reduced. Because the side edges are downwards inclined, the resistance of cold air blown from the top is reduced, the air velocity is accelerated, the convection heat radiation effect is better, and dust is prevented from staying in gaps of the heat radiation fins.
Description
Technical field
The utility model relates to a kind of radiator, relates in particular to a kind of cpu heat.
Background technology
CPU is the core component of computer, also is the main heater members of system, and its temperature is too high will to cause that performance significantly descends, and work that can not be reliable and stable if be in the operating state of excessive temperature for a long time, will have a strong impact on its useful life.In order to make the CPU operate as normal, must effectively dispel the heat to it, present employed radiating mode has air blast cooling mode, heat pipe mode, liquid cooling mode, wherein air blast cooling mode is exactly to utilize fan that the heat of fin is scattered and disappeared by the forced convertion mode, be characterized in simple in structure, cost is low, volume is little, be easy to install, and becomes topmost radiating mode.
Though the air cooling way radiator is widely used, but have radiator temperature skewness, problem that duct resistance is big, radiating effect has much room for improvement, and after long-time the use, the many dusts of accumulation have had a strong impact on the heat loss through convection effect between radiating fin.
The utility model content
The utility model is made the radiating effect that improved at above-mentioned defective to the structure of radiator, prevents the accumulation of dust.
To achieve these goals, the technical solution adopted in the utility model is: designed cpu heat, comprise radiating fin and the heat absorption base plate that is connected described radiating fin lower end, and the thickness at described heat absorption base plate center is greater than the thickness at edge.
Preferably, the side of the vertical cross-section of described heat absorption base plate is a straight line.
Preferably, the side of the vertical cross-section of described heat absorption base plate is a camber line.
Preferably, the arc-shaped transition that is connected to of described radiating fin and described heat absorption base plate is connected.
After adopting this structure, radiator in light weight, uniformity of temperature profile, the resistance that wind is subjected to reduces, and wind speed strengthens, heat loss through convection effective, and reduced the gathering of dust effectively.

Embodiment
Down protection range of the present utility model is being described in conjunction with specific embodiments.
Fig. 1 is embodiment one, radiating fin temperature height, heat absorption base plate peripheral part and the low defective of edge radiating fin temperature of, heat absorption baseplate centre portion identical and connection thereof at existing radiator heat absorption base plate thickness, change the thickness of heat absorption base plate, make core thickness big, brim-portion thickness is little, helps heat and is delivered to marginal portion and radiating fin thereof faster.Specifically, the utility model is made of fan 1, radiating fin 2, heat absorption base plate 3 three parts, fan 1 is installed in the top of radiating fin 2, radiating fin 2 radially distributes, and radiating fin 2 lower ends connect heat absorption base plate 3, and heat absorption base plate 3 lower surfaces closely contact with CPU, the thickness of heat absorption base plate 3 cores is big, the marginal portion is thinner, and its vertical cross-section is trapezoidal, and side 31 is downward-sloping.When heat absorption base plate 3 absorbed the heat of CPU generation, easier marginal portion and the top radiating fin 2 thereof of being delivered to made the temperature of radiator even, also alleviated the weight of radiator simultaneously; Because side 31 is downward-sloping, the resistance that the cold wind that the top blows is subjected to reduces, and wind speed is accelerated, and the better effects if of heat loss through convection has prevented that dust is trapped in the slit of radiating fin 2.
Fig. 2 is embodiment two, basic identical with the structure of embodiment one, difference be the to absorb heat side 32 of base plate 3 vertical cross-sections is arc, radiator heat absorption base plate 3 upper surfaces are designed to along arc direction by middle mind-set edge tilt, reduce the resistance of wind more effectively, make the more uniform temperature of radiator, speed is faster, and radiating effect is better.
Fig. 3 is embodiment three, for resistance, the quickening wind speed that further reduces wind, in embodiment three shape of radiating fin 2 and heat absorption base plate 3 coupling parts 4 is optimized, and is designed to arc-shaped transition and connects, and has further improved radiating effect.
The above only is preferred embodiment of the present utility model, and not in order to restriction the utility model, common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement should be included in the protection range of the present utility model.
