Strengthen blast heat radiation module
The utility model relates to radiator, the heat radiation module of the enhancing blast of specifically a kind of desktop computer and electronic product use.
Because electronic component can produce heat energy when power consumption, the time that electronic component uses is longer, and the heat of generation will be more.Electronic component has its normal operating temperature range, if the temperature of electronic component itself exceeds this operating temperature range, electronic component useful life is reduced, and is directed at electronic component and burns out.Therefore, electronic component adopts good radiator structure to seem very important.
The caloric value of existing electronic component is increasing, and for satisfying the heat radiation requirement, the air pressure air flow of corresponding radiator heat-dissipation area and fan also need strengthen.When fan strengthened air pressure air flow, the energy consumption of the fan of following was strengthening, and noise is also increasing simultaneously.Actual is to want low energy consumption at application requirements, low noise, but satisfy again the requirement of dispelling the heat.In the prior art, the air pressure air flow of heat radiation module is not strong, and radiating effect is not ideal enough.
The utility model content
Technical problem to be solved: the utility model is not enough for prior art, provides a kind of in the situation that same consumption energy, can strengthen the heat radiation module of blast.
Technical scheme: a kind of enhancing blast heat radiation module, comprise radiator, axial flow blower, be provided with air deflector between described radiator and the axial flow blower.
Described air deflector periphery has an outer shroud, and a bearing is established at the air deflector center, the flow deflector that has several to arrange separately in the bearing periphery; Center, described radiator upper end is established a water conservancy diversion axle core and is used for fixed deflector.
Described axial flow blower periphery is provided with rotary buckle, and described radiator periphery is provided with screw rod, and rotary buckle is fixed on the screw rod.
The utility model beneficial effect:
The effect of front air deflector be make air-flow impeller eye produce negative rotation around, to improve the total head of axial flow blower; The blade of front air deflector is often made and can be rotated around own axis in addition, can change the operating mode of ventilation blower by changing the blades installation angle.Leave the air-flow of impeller, generally have winding speed and correspondingly curl up kinetic energy, this kinetic energy forever is depleted to friction loss and consists of on the vortex.In order to take full advantage of this part kinetic energy behind the impeller, can be after the impeller back arranges air deflector.
Air deflector is common in large-scale ventilating machinary, the collocation form that utilizes the design of NACA cascade data is arranged: stator blade-movable vane type at small-sized axial flow fan (electronic radiator fan); Movable vane-stator blade type; Stator blade-movable vane-stator blade type; But join type, total pressure efficiency: 0.72-0.82 for above 3 kinds.Less than the total pressure efficiency that increases air deflector: 0.8-0.9.
The utility model is air deflector after radiator is installed an axial flow blower; Air deflector (impeller+rear air deflector after axial flow blower is installed behind impeller; The R+S level), its purpose is can be partly even utilize fully impeller outlet to curl up kinetic energy improving the blast of axial flow blower, and axial flow blower efficient also correspondingly is improved.The characteristics of this level pattern are general total pressure efficiency: 0.8-0.9.And the axial flow blower total pressure efficiency of single-stage (R level): 0.72-0.82; So total pressure efficiency of the present utility model can obtain the poorest-0.02 to best+0.18 in the theory design.General design can improve 0.08 total pressure efficiency.
Riveted air deflector axle core on radiator.Air deflector is installed on the radiator.Bearing arrangement can be oiliness bearing by the demand of design, ball bearing etc.Axial flow blower uses the mode of rotary buckle to be fixed on the screw rod of radiator.Present integrated heat radiation module, and rotary buckle can be saved the man-hour of locking screw, the cost that reaches screw.
Air deflector is installed on the radiator, rather than is installed on the axial flow blower.The size of axial flow blower does not change.Because the blade profile of air deflector and axial flow blower is matched.So on the secondary market, broken such as axial flow blower, just must will buy back the axial flow blower of original that manufacturer.
In sum, the utility model can improve axial flow blower efficient, strengthens blast, good heat dissipation effect.

Number in the figure representative: radiator 1, axial flow blower 2, air deflector 3, outer shroud 4, bearing 5, flow deflector 6, water conservancy diversion axle core 7, rotary buckle 8, screw rod 9, screw rod fixture 10.
The utility model is described in further detail below in conjunction with embodiment.
See Fig. 1-3, a kind of enhancing blast heat radiation module comprises radiator 1, axial flow blower 2, is provided with air deflector 3 between described radiator 1 and the axial flow blower 2.
Described air deflector 3 peripheries have an outer shroud 4, and a bearing 5 is established at air deflector 3 centers, in bearing 5 peripheries several flow deflectors that arranges separately 6 are arranged; Center, described radiator 1 upper end is established a water conservancy diversion axle core 7 and is used for fixed deflector 3.Water conservancy diversion axle core on the radiator, the available technique such as press is fixed on the radiator.Air deflector is provided with outer shroud, and the fluid that is used for blower fan is concentrated down to radiator, and is not interposing at the diffusion of fluid neighboring, and produces loss.
Described axial flow blower 2 peripheries are provided with rotary buckle 8, and described radiator 1 periphery is provided with screw rod 9, and rotary buckle 8 is fixed on the screw rod 9.Screw rod 9 is fixed in the radiator 1 by screw rod fixture 10, and axial flow blower 2 rotating shafts are located in the bearing 5.
The present embodiment screw rod is provided with four, four of rotary buckles.The flow deflector number of air deflector is equipped with by the performance of actual design and axial flow blower.
Axial flow blower is installed on the air deflector, and when axial flow blower was dried from top to bottom, the function of air deflector was rear air deflector; When axial flow blower was dried from the bottom up, the function of air deflector was front air deflector.The heat radiation module is installed an air deflector, and an air deflector can be installed above axial flow blower again, the combination of air deflector before and after forming.
The above person, it only is the preferred embodiment of the utility model, it is not the scope that limits the utility model, therefore have in the technical field under being somebody's turn to do and usually know the knowledgeable, or be familiar with this technology and done equivalence or variation person easily, change and modification in the spirit that does not break away from the utility model and the lower equalization of being done of scope, all should be covered by in the claim of the utility model.
