It invents rather than requires the present invention that must be constructed and operated in a specific orientation, therefore be not considered as limiting the invention.
Term "front", "rear" used in present invention description, "left", "right", "upper", "lower" refer to the direction in attached drawing, term
"inner", "outside" refer respectively to the direction towards or away from geometric center of specific component.
The specific embodiment of the invention provides a kind of heat radiation protection device for electric wheelchair clutch, such as Fig. 1 and
It is the outwardly and inwardly structural schematic diagram of the embodiment of the present invention respectively shown in Fig. 2.Described device includes containing clutch 6
Shell 1, shell 1 are hinged with protective door 2, and protective door 2 can be turned out unlatching along the shaft of hinged place, and 1 upper surface of shell is solid
Surely it is connected with heat sink 3,3 upper surface of heat sink is equipped with several equally distributed heat release holes 5.Shell 1 and protective door 2 play protection
The effect of clutch 6, to avoid suffering damage under shell 1 and protective door 2 hot conditions caused by clutch 6,1 He of shell
Protective door 2 is generally made of the high temperature resistants material such as glass fibre, ceramic fibre;For the heat conduction for quickly generating clutch 6
To heat sink 3, shell 1 is made of heat-conductings such as aluminium, iron.In the present embodiment, shell 1 selects aluminium material production, not only thermally conductive
Performance is good, and lighter weight;Protective door 2 selects the production of glass fibre material.
It is fixedly connected inside shell 1 there are two heat-conducting plate 7, the heat-conducting plate 7 is L shape heat-conducting plate, two heat-conducting plates 7
Above clutch 6 and symmetrical laying.7 lower end surface of heat-conducting plate is waveform curved surface, in favor of increasing and clutch 6 weeks
The contact area of air is enclosed, to more fully absorb the heat that transmitting is generated by clutch 6.7 lower end surface of heat-conducting plate it is specific
Shape, as shown in figure 3,7 lower end surface of heat-conducting plate, which is dug, multiple equally distributed semicircle shape grooves 11, two neighboring semicircle shape is recessed
Semicircle shape protuberance 12 is equipped between slot 11, to form waveform curved surface.1 left and right side of shell, which is dug, opposite two laid
Through-hole 4,1 inside of shell are also fixedly connected there are two exhaust fan 9,9 outlet air end face through-hole 4 of exhaust fan, and an exhaust fan 9 is corresponding
One through-hole 4.Through-hole 4 and exhaust fan 9 are respectively positioned on the top of heat-conducting plate 7, and heat-conducting plate 7 conducts the heat that clutch 6 generates to leading
The cavity that 7 upper surface of hot plate and shell 1 are constituted, 9 via through holes 4 of exhaust fan are by the outside dissipation of heat.To avoid external dust from passing through
Through-hole 4 enters inside apparatus of the present invention, in turn results in pollution or even damage device internal structure, 4 inner wall of through-hole are equipped with Air Filter.
1 inside of shell is also fixedly connected there are two refrigeration semiconductor 8, which is located at 7 top of heat-conducting plate
And symmetrical laying, play the role of reducing cavity inner temperature.7 upper surface of heat-conducting plate is equipped with blotting paper, on heat-conducting plate 7
End face outer rim is equipped with baffle, and 6 surface of clutch is equipped with waterproof layer.When apparatus of the present invention are in hot humid environment, by
In the refrigeration of refrigeration semiconductor 8, so that the intracorporal vapor of chamber liquefies afterwards to the cold condenses into droplet, on heat-conducting plate 7
Blotting paper can absorb the droplet in time, it is avoided to drop on clutch 6, while the evaporation of the moisture by absorbing droplet
To improve heat dissipation effect.When ambient humidity further increases, cause vapor liquefy to the cold generation water droplet it is more when, set on leading
The baffle of 7 upper surface outer rim of hot plate is it is possible to prevente effectively from water droplet drops onto 6 surface of clutch along heat-conducting plate 7.Even if there is a small amount of water
