The specific embodiment
Be described further in conjunction with the specific embodiment of accompanying drawing the utility model.
1, structure of the utility model and principle of work.
The utility model comprises explosion-proof heater motor 3, ventilating set 4, radiator 12; The ventilating set housing 13 that ventilating set 4 comprises the snail shape with and the impeller 9 of interior setting; Paddle shaft connects the output shaft of explosion-proof heater motor 3; The axial of impeller 9 is the air intake direction of ventilating set, and the radially cooresponding ventilating set housing 13 of impeller is provided with air outlet 8.Radiator 12 is installed on the radiator mounting box 6; From-inner-to-outer is equipped with anti-protection pad 11, grille guard 10 on the radiator mounting box 6 of radiator 12 1 sides; The radiator mounting box 6 of radiator 12 opposite sides connects ventilating set ventilation inlets 5, radiator 12 through radiator tank interface 7 and rubber-tired cart the cycle of engine system link to each other.The radiator tank interface is provided with conduit switch.
The utility model unit design is tight, and motor part is divided into flame-proof type, and blower fan partly is the snail shell structure; Windage is very little; Radiator links to each other with the cycle of engine system, and the size that switch is controlled current can be set, thereby control sucks the size of operator's compartment heat.Principle of work: driven by motor impeller rotation, the heat of spreader surface is sucked heater, blow out by air outlet again, arrive operator's compartment through airduct, thereby reach the purpose of heating and demist, defrosting.If conduit switch is closed, this device also can be used for the ventilation in vehicle summer and enjoys the cool.
2, explosion-proof heater motor.
The described electrical motor of the utility model is explosion-proof heater motor, is specially under the DBNF-50/24J moulded coal mine rubber-tired cart and uses the flame-proof type heater motor.According to State Standard of the People's Republic of China GB3836.1-2000 " explosive gas atmosphere electrical installation first: general requirement ", the design of GB3836.2-2000 relevant criterion such as " explosive gas atmosphere electrical installation second portions: flame-proof type " d " ".It adopts flameproof enclosure to separate electric part that possibly produce spark, electric arc and dangerous temperature and explosive gas mixture on every side.Make its explosive gas mixture on every side that can not ignite.Power of motor is 50W, and the explosion-proof ExdI that is masked as can be applied to the place of imflammable gas or steam and the explosive mixture that air forms of operating temperature-20 ℃～+ 40 ℃, average relative humidity＜95% (+25 ℃ time), barometric pressure: 80～110kPa; The main body cover degree of protection is IP54, and the connection box degree of protection is IP54; Rated voltage is: DC24V, and rated operational current: 4A, the electrical machine insulation grade is the F level.
3, according to the real space of existing vehicle, select the fan and the radiator of suitable size for use, confirm the profile of being convenient to install.The flame-proof type heater unit according to China Machine Press publish " related content of blower fan handbook " Specifeca tion speeification of chapter 2 blower fan " " the first segment performance perameter is confirmed " is carried out type selecting to blower fan; The ventilation volume of the every square meter area of air output is poisonous, imflammable gas chamber 35 m3/ (hm2); So ventilation volume hourly is 3 * 35=105 m3/h in the operator's compartment, the rubber-tired cart operator's compartment inner volume that my company produces at present is greatly about about 3m3; So when selecting fan impeller, just requiring its air quantity is 105 m3/h; Principle is mated suitable fan and air outlet in view of the above.After trial-production and improving, this device air outlet wind speed is 12m/s, and the air outlet sectional area is 0.002513 m2, calculates and learns that the air outlet air quantity of heater is 3600 * 12 * 0.002513=108.56 m3/h, adheres to specification.As shown in Figure 1: insert 24V storage battery 1, will be with locking press button switch 2 closures, 3 of flame-proof type heater units get into mode of operation.
Like Fig. 2,3,4, shown in 5: when the flame-proof type heater unit rotated, gas got into from grille guard, advanced to prevent that protection pad filtered; Pass radiator; With the heat suction ventilation machine ventilation inlet on the radiator, get in the impeller, because the mode of operation of fan impeller is axial entering; Radially flow out, will flow out from air outlet so get into the heat of impeller.
