Detailed description of the invention

Describe the technical solution of the utility model below in conjunction with the accompanying drawings with embodiment in detail, but protection domain is not limited to this.

Embodiment: centrifugal High-temp. smoke-exhausting fan, as shown in Figures 1 to 3, including housing 1, blade wheel 2, rotating shaft, motor 3, Belt drive unit 4 and belt box 5, blade wheel 2 is rotatably arranged in housing 1 by rotating shaft, and housing 1 is located at by motor 3 Outside, motor 3 is connected with rotating shaft transmission by belt drive unit 4.Motor 3 drives rotating shaft to revolve by belt drive unit 4 Turn, and then drive the blade wheel 2 being located in rotating shaft rotation in housing 1, thus be centrifuged exhaust work.

As shown in Figure 4, belt box 5 protects outside belt drive unit 4, its outside covering semiconductor refrigerating module 6 of belt box 5. Described semiconductor refrigerating module 6 includes PN joint cold-making block 61, wire 62 and power supply 63.One layer of insulation material it is surrounded by outside belt box 5 Material 64, the cold end of PN joint cold-making block 61 is mutually bonding with the insulant 64 wrapped in outside belt box 5 and is evenly distributed on belt box 5 Around.Power supply 63 provides work energy by wire 62 for PN joint cold-making block 61.After energising, save cold-making block 61 at PN Cold end produce low temperature, it is outer thus reduce the temperature in belt box 5 that low temperature surrounds belt box 5.Low temperature around belt box 5 is protected Protect and can effectively prevent under fire hazard environment temperature in belt box 5 to rise sharply and cause the belt of belt drive unit 4 to be got loose by thermal softening And cannot work.

Being additionally provided with temperature feedback system outside belt box, temperature feedback system includes that temperature information acquisition module, temperature information transmit Line and temperature indicator, temperature information acquisition module is placed in the insulant between the cold end of belt box 5 and PN joint cold-making block 61 In 64, the temperature signal gathered is passed to temperature indicator by temperature information transmission line by temperature information acquisition module, thus Realize the temperature of belt box 5 is monitored in real time and checked.
