Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
A kind of automotive defroster, comprises housing 1, is arranged on heat radiation core body above enclosure interior, is arranged on blower fan assembly, coolant inlet pipe 2 and coolant outlet pipe 3 below enclosure interior.Described housing 1 upper surface is provided with six air outlets, air outlet place is provided with blast connection 4, blast connection 4 is for connecting defrosting air pipe, defrosting air pipe is connected with the universal air outlet on instrument desk, described housing 1 lower surface is provided with multiple ventilation inlet 5, described housing bottom surface the right and left has the extended surface protruding housing left and right sides respectively, each extended surface is provided with two mounting holes 6, for defogger is installed to automobile, the inner side of described housing 1 four sides is provided with the heat-insulation layer 7 that material is phenol formaldehyde foam, effectively can reduce heat consume, improve heat utilization ratio.Described heat radiation core body comprises radiating gill 8 and the cooling pipe 9 on radiating gill 8 that interts, the starting end of described cooling pipe 9 is connected with coolant inlet pipe 2 and coolant outlet pipe 3 respectively with end end, cooling pipe 9 can be ordered arrangement on radiating gill 8 also can be unordered arrangement, it is ordered arrangement described in Fig. 2, achieved a fixed connection by the mode of welding between radiating gill 8 and cooling pipe 9, described radiating gill 8 is flat shape, radiating gill 8 is provided with multiple kidney-shaped hole 10, spacing ring 11 is provided with between adjacent two radiating gills 8, described cooling pipe 9 is welded into by two kinds of highly different U-tube are alternate, only form weld layer 12 at one section of heat radiation core body, decrease the quantity of weld layer, be conducive to the mechanical strength improving heat radiation core body, and then improve the service life of defogger.Described heat radiation core body two sides are provided with pedestal 13, and pedestal is connected with heat radiation core body by the mode of soldering, and is fixedly connected with housing 1 by screw.Described blower fan assembly comprises impeller 14 and motor 15, described impeller 14 and motor 15 are arranged on blower fan assembly bracket 16, blower fan assembly bracket 16 is provided with impeller putting hole, and impeller 14 places impeller putting hole place, and described blower fan assembly bracket 16 is fixedly connected with housing 1 by bolt.It is inner that described coolant inlet pipe 2 and coolant outlet pipe 3 stretch out housing 1, and on coolant inlet pipe 2 and coolant outlet pipe 3, cover has soft foam-rubber cushion 17, can effectively prevent the cold airflow entering housing 1 from ventilation inlet 5 from directly not flowed out from air outlet by heating, the heating effect of reduction defogger.
