Abstract
The utility model discloses a radiating device of a frequency conversion motor, which comprises two cooling circuits, the two cooling circuits are respectively arranged at two ends of the frequency conversion motor, each cooling circuit is respectively provided with vanes, a wind guide cover and a wind guide plate, and rotating directions of the two vanes are opposite. The radiating device has the advantages that the vanes are symmetrically installed on two sides of the generator, the rotating directions of the two vanes are opposite, so that cooling air respectively enters from two ends when a machine runs, convection current is produced by blowing of air in the two opposite directions. The radiating device adopts the technical scheme with double-vane convection cooling design. The motor adopting the radiating device is more reasonable in radiating effects and greatly improves motor utilization efficiency.
Description
Technical field
The present invention is a kind of frequency conversion generator heat abstractor, and especially a kind of have two fan blade heat loss through convection design systems.
Background technology
Along with rapid economy development, the raising of people's living standard; A kind of----frequency conversion generator as emergency power supply is liked by people more and more; And the subject matter----that hinders the frequency convertor high speed development is dispelled the heat, and has caused and has shown great attention to.
Though common frequency convertor cooling system is made up of two heat radiation fan blades, the inlet of cooling air, the outlet of cooling air all are in same direction; Mainly there is following problem in this cooling system structure:
1: because the structure problem of frequency convertor own cause motor radiating air inlet resistance to become big, and motor cooling air that air inlet advances is a power heat radiation hot-air later, causes the motor radiating weak effect.
2:, cause heat radiation range limited because wind direction is single; The heat radiation of all multi-parts less than or radiating effect poor.
The utility model content
The technical problems to be solved in the utility model provides frequency conversion generator heat abstractor comprehensively a kind of or that repeatedly dispel the heat.
In order to solve the problems of the technologies described above, the technical scheme that its technical problem that solves the utility model adopts is: a kind of frequency conversion generator heat abstractor is provided, comprise two cooling circuits, two cooling circuits are separately positioned on the two ends of frequency conversion generator, each cooling circuit is respectively equipped with fan blade, wind scooper and wind deflector, and the rotation direction of two fan blades is opposite;
Cooling circuit A: the air intake inlet of cooling circuit A is arranged on the frequency converter place, fan blade A is arranged on the air intake inlet of frequency converter, cooling circuit A approach handle tray, after the frequency convertor wind scooper is arranged on handle tray, make cooling circuit A approach cylinder head and muffler by the frequency convertor wind scooper, described cylinder head is provided with wind deflector;
Cooling circuit B: the air intake inlet of cooling circuit B is arranged on the motor place, fan blade B is arranged on the air intake inlet of motor, described motor is provided with the motor wind scooper, makes cooling circuit B approach generator unit stator, generator amature, crankcase cover, muffler and starter by the motor wind scooper.
Wherein, the cooling air of described cooling circuit A and cooling circuit B bumps against the formation convection current at the fuel tank outer surface.
Wherein, described motor wind scooper adopts 360 ° of full week designs.
The beneficial effects of the utility model are, in the generator bilateral symmetry fan blade is installed, the rotation direction of two fan blades is opposite, cooling air was respectively from the two ends air intake when therefore machine moved, the incorgruous operation of wind direction produces convection current, be a kind of technical scheme, adopt this heat abstractor motor radiating effect even more ideal, improve the motor utilization ratio greatly with two fan blade convection current Cooling Design.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the plane graph of the utility model frequency converter heat abstractor;
Fig. 2 is the cutaway view of the utility model frequency converter heat abstractor;
Wherein, 1: frequency converter; 2: handle tray; 3: the frequency converter wind scooper; 4: wind deflector; 5: cylinder head; 6: muffler; 7: fan blade A; 8: the motor wind scooper; 9: generator unit stator; 10: generator amature; 11: crankcase cover; 12: starter; 13: fan blade B.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 1 and Fig. 2, this a kind of frequency conversion generator heat abstractor, comprise two cooling circuits, two cooling circuits are separately positioned on the two ends of frequency conversion generator, each cooling circuit is respectively equipped with fan blade, wind scooper and wind deflector 4, fan blade is installed in the two ends of machine, and the rotation direction of two fan blades is opposite;
Cooling circuit A: the air intake inlet of cooling circuit A is arranged on frequency converter 1 place, fan blade A7 is arranged on the air intake inlet of frequency converter 1, cooling air enters from the inlet of frequency converter 1 under the effect of fan blade A7, enter frequency converter wind scooper 3 by way of handle tray 2, frequency converter 1 is under the effect of frequency converter wind scooper 3, and a cooling air part flows out from frequency converter wind scooper 3 tops; Part cooling air flows out from the wind scooper below, under the effect of wind deflector 4, flows out from the exhaust outlet below then by way of cylinder head 5, flows out behind muffler 6 guard shields.The characteristics in this loop are to make full use of the air-flow that fan blade A7 produces, the heat that produces when cooling off the operation of frequency converter 1 and engine.
Cooling circuit B: the air intake inlet of cooling circuit B is arranged on the motor place, fan blade B13 is arranged on the air intake inlet of motor, under the effect of fan blade B13, cooling air enters from the inlet of motor wind scooper 8, flow out by way of generator unit stator 9, generator amature 10 backs, cooling air and crankcase cover 11 bumps against the back and forms reflection, flows out after entering muffler 6 guard shields; Part cooling air directly cools off starter 12; Another part directly flows out from motor wind scooper 8 tops.
In the present embodiment, the cooling air of described cooling circuit A and cooling circuit B bumps against the formation convection current at the fuel tank outer surface.
By fan blade being installed in the generator bilateral symmetry, the rotation direction of two fan blades is opposite, cooling air was respectively from the two ends air intake when therefore machine moved, the incorgruous operation of wind direction produces convection current, it is a kind of technical scheme with two fan blade convection current Cooling Design, adopt this heat abstractor motor radiating effect even more ideal, improve the motor utilization ratio greatly.
In this enforcement because motor wind scooper 8 adopts 360 ° of full week designs, so the air-flow that produced of fan blade B13 can comprehensive cooled electric generator stator 9, rotor.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
