Description
Technical field
The utility model relates to a kind of ventilation and heat equipment appurtenance, particularly a kind of stream guidance fan housing be located between radiator and fan.
Background technology
Existing household electrical appliances air-conditioning or car air-conditioner are equipped with ventilation and heat equipment, its core parts are radiator and fan, and exhausting is responsible for by its fan, and air-flow is directionally passed through radiator, and therefrom discharge in hot equipment, thus realize the effect of air cooling cooling to external world;
Stream guidance fan housing (also claiming wind scooper or kuppe) wherein will be set between radiator and fan, and seal the junction of stream guidance fan housing and radiator, when preventing fan exhausting, outside air enters fan from blow-by short-circuit flow, the air quantity flowing through radiator is reduced, the radiating effect of radiator is declined.
Existing stream guidance fan housing is set up in housing, air intake vent relative narrowness, only relies on fan to be pumped in ventilation and heat equipment by the air outside ventilation and heat equipment.Such ventilation and radiating efficiency lower.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of reinforced stream guidance fan housing contributing to improving ventilation and radiating efficiency.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
Reinforced stream guidance fan housing, is applied in the ventilation and heat equipment be made up of radiator and fan, comprises fan housing main body and vertical supporting axle and annular backup pad;
Fan housing main body comprises the straight tube of a upper and lower opening and is located at the supporting seat of straight tube top and bottom, and wherein apical support seat is fixed on ventilation and heat apparatus casing, and bottom supporting seat is located at outside ventilation and heat apparatus casing, and straight tube is located in annular backup pad;
There is the annular backup pad described in a group along straight tube axially-aligned, the straight tube between adjacent annular gripper shoe offers air vent; Vertical supporting axle circumference is distributed in the outside of straight tube, and through each annular backup pad be fixed on the supporting seat of bottom, and the top of straight tube and bottom are equipped with the connector for installation of heat radiator.
Adopt the technical solution of the utility model, there is following technique effect:
1, stream guidance fan housing is external, using the passage that the air vent of straight tube bottom end opening and straight tube sidewall exchanges as ventilation and heat equipment and outside air, compared with single ventilation mouth, expand the probability of ventilation and heat equipment and contacting external air.
2, arrange the connector of installation of heat radiator respectively in straight tube bottom and top, whole like this ventilation and heat equipment is just divided into two steps to carry out ventilation and heat, after passing into the radiator of straight tube bottom, has carried out preliminary heat radiation at air; Inner in straight tube, the air through preliminary heat radiation mixes with the air by air vent, and under the impact of fan suction force, the air guided radiator to straight tube top in straight tube moves; Due to obviously can be larger than air vent aperture by the bore of straight tube bottom, from ventilation, the major air that enters ventilation and heat equipment be through double-radiation function, and radiating efficiency is higher; With entering extraneous horizontal wind, can very naturally enter in straight tube, effectively utilize extraneous air advection, when fan power is certain, intake be more.
To sum up, adopt the reinforced stream guidance fan housing of the utility model to have double-radiation function usefulness, effectively utilize air advection, increase the efficiency of ventilating and dispelling the heat to a certain extent.
Further, the internal orifice dimension of described annular backup pad is greater than straight tube barrel dliameter 2 ~ 3cm, and described annular backup pad is spliced by left and right two pieces of symmetrical daughter boards.
If when the size of annular backup pad and straight tube barrel dliameter is less, if annular backup pad is integral type structure, likely cannot by the supporting seat of top and bottom, the annular backup pad that described employing is split type.
Further, described apical support seat is installed with one group of fin-shaped fin.
Because apical support seat is fixed on housing, bottom supporting seat is outside housing, and the fin-shaped fin on such apical support seat, will in housing; In housing, set up fin during air intake contribute to improving radiating efficiency.
Further, described connector comprises joggle hole, alignment pin or pipe joint.
According to different radiator features of shape, select different connectors.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the cross-sectional schematic of the reinforced stream guidance fan housing embodiment of the utility model;
Fin-shaped fin 1, pin 2, three-dimensional ribbed pipe 3, straight tube apical support seat 4, annular backup pad 5, straight tube bottom supporting seat 6, air vent 7, opening 8, rubber hose 21.
Detailed description of the invention
As shown in Figure 1, the reinforced stream guidance fan housing of the utility model, is applied in the ventilation and heat equipment be made up of radiator and fan, comprises fan housing main body and vertical supporting axle and annular backup pad 5;
Fan housing main body comprises the straight tube of a upper and lower opening 8 and is located at the supporting seat of straight tube top and bottom, wherein straight tube apical support seat 4 is fixed on ventilation and heat apparatus casing, straight tube bottom supporting seat 6 is located at outside ventilation and heat apparatus casing, and straight tube is located in annular backup pad 5;
There is the annular backup pad 5 described in a group along straight tube axially-aligned, the straight tube between adjacent annular gripper shoe 5 offers air vent 7; Vertical supporting axle circumference is distributed in the outside of straight tube, and through each annular backup pad 5 being plugged on straight tube bottom supporting seat 6.
Described radiator adopts cut fin quarter on three-dimensional ribbed pipe 3(tube wall disclosed in Chinese patent CN203037126), wherein feed liquor (cooling fluid) pipe of three-dimensional ribbed pipe 3 is led in/out in ventilation and heat equipment by rubber hose 21 with drain pipe.Three-dimensional ribbed pipe 3 is by joggle hole joggle in straight tube bottom, and three-dimensional ribbed pipe 3 is positioned at straight tube top by pin 2.
The internal orifice dimension of described annular backup pad 5 is greater than straight tube barrel dliameter 2.5cm, and described annular backup pad 5 is spliced by left and right two pieces of symmetrical daughter boards.Described apical support seat is installed with one group of fin-shaped fin 1.
For a person skilled in the art, under the prerequisite not departing from the utility model structure, can also make some distortion and improvement, if vertical supporting axle is multidiameter, annular backup pad 5 and the junction of back shaft are the supported holes of one group of corresponding size; These also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
