For preventing that the too high generator that influences of temperature normally moves in the cabin; The engine room cover top of gear-box top is provided with adjustable scavenge port; The engine room cover afterbody be equipped with can be public with the generator cooling fan the can regulate ventilating fan; The inside and outside temperature transducer of respectively establishing of engine room cover, said temperature transducer connects the control centre of peripheral hardware, and control centre regulates ventilating fan speed and scavenge port size.Regulate ventilating fan and scavenge port size in the cabin through temperature transducer feedback temperature outside temperature transducer in the cabin and the cabin, control cabin and ambient air exchange velocity make the interior temperature maintenance of blower fan in the blower fan optimum Working.This kind design can continue heat supply to engine room inside, avoids day and night temperature to cause the dewfall phenomenon greatly; In addition, the present invention can make in the cabin and form heat exchange between the air and gear-box fluid, can guarantee that temperature can not hanged down excessively in the cabin in winter and need not extra-heated through regulating cabin scavenge port and ventilating fan.
For ease of maintenance, the heating cabinet bottom also is provided with the drain tap of band oil drain valve.This design, fluid in the heater of being convenient to when safeguarding, release.
As a kind of improvement project of the present invention, the aforementioned temperature sensor all adopts the PT100 temperature transducer.
For further being convenient to maintenance, the horizontal hierarchal arrangement of heating pipe in the heating cabinet.The heating pipe that is uniformly distributed with is convenient for changing.
As a kind of improvement project of the present invention, said gravity assisted heat pipe adopts the heat pipe with thermal diode and thermal switch property, and it only is higher than 40 in the evaporator section temperature
oAbility one-way heat conduction during C.
For further improving radiating efficiency, the evaporator section of aforementioned gravity assisted heat pipe and liquid level inclination angle are 75-80 °, and evaporator section at least 2/3 stretches into lubricant oil inside.Arrange on the one hand so the radiating efficiency of heat pipe own is maximized the use, also increased with the air area of contact and improved radiating efficiency, and can regulate between radiating fin apart from guaranteeing that the fin temperature is more than dewfall point.
