Compared with a fuel oil heating mode, the heating device has higher heat efficiency and is cleaner. The lowest temperature of low-temperature air output by the cold air end of the vortex tube 2 can reach-46 ℃, the efficiency of cooling the generator can be effectively improved, and even cooling equipment on the generator can be omitted. In addition, on the basis that the vortex tube 2 introduces cooling air into the generator, the air inflow of the cooling air in the generator is reduced. Therefore, the area of the air inlet passage of the internal combustion generator set can be properly reduced, and the noise of the internal combustion generator set can be reduced.
In an embodiment of the present invention, the air feeding mechanism 1 includes an air compressor 11 and a dryer 12, the air compressor 11 is connected to an input end of the dryer 12, an output end of the dryer 12 is connected to an air inlet end of the vortex tube 2, and the air compressor 11 dries compressed air by the dryer 12 and then feeds the dried air into the vortex tube 2.

In an embodiment of the present invention, a hot gas end of the vortex tube 2 is connected to a heating medium inlet of the heat exchanger 3 through a first pipeline, a cooling medium inlet of the heat exchanger 3 is connected to a water outlet of the internal combustion engine water circulation system 41 through a second pipeline, and a cooling medium outlet of the heat exchanger 3 is connected to an inlet of the internal combustion engine water circulation system 41 through a third pipeline; the high-temperature air sent into the heat exchanger 3 by the vortex tube 2 transfers heat to the water sent into the heat exchanger 3 by the water circulation system, and the heated water returns to the internal combustion engine water circulation system 41 to heat the internal combustion engine set. Meanwhile, low-temperature air output by the cold air end of the vortex tube 2 is directly introduced into the generator 5 to cool the stator, the rotor, the bearing and other parts of the generator, so that reliable insulation and safe and efficient operation of the generator are ensured. Specifically, the cold air end of the vortex tube 2 is connected with the inlet of the cooling pipeline of the generator 5 through an air tube, or is connected with the air inlet of the generator 5 through a pipeline.

The heat exchanger exchanges heat with the liquid using air. In addition, a valve may be disposed at the heat medium outlet of the heat exchanger 3, so as to avoid the influence of the internal combustion engine 4 cooling effect caused by the internal combustion engine water circulation system 41 still heating the internal combustion engine 4 after the internal combustion engine set is normally started. After the internal combustion generator set is normally started, a valve at a heat medium outlet of the heat exchanger 3 is controlled to be opened, high-temperature air sent into the heat exchanger 3 by the vortex tube 3 can be directly discharged out of the heat exchanger 3 before heat exchange with water, at the moment, the water sent into the heat exchanger 3 by the water circulation system 41 cannot be heated and directly returns to the internal combustion engine 4, and the internal combustion engine 4 can still be cooled by a heat conducting medium in the water circulation system 41.

Therefore, the heated water can be transported to the positions requiring heating, such as the engine case and the oil pan, respectively, by the engine water circulation system 41. It should be noted that the water path connection of the water circulation system 41 of the internal combustion engine is not limited to this, and the water circulation system may also be connected to the fuel system of the internal combustion engine, and the heated water may be delivered to the fuel system to directly heat the fuel. In addition, a liquid-liquid heat exchanger can be additionally arranged at the front end of the fuel pipeline, and the heat exchange between the heated water and the fuel is realized through the heat exchanger to realize the heating of the fuel. Therefore, the low-temperature starting device is flexible in arrangement, and can simultaneously solve the problem that the internal combustion power generation equipment needs to be heated and cooled under the low-temperature condition.

Set up temperature sensor around the internal combustion generating set, utilize temperature sensor to gather internal combustion generating set ambient temperature and send to the controller, when ambient temperature is less than predetermined temperature range, can judge that internal combustion generating set can't normally start this moment, control air feed mechanism 1 through the controller and send compressed air to vortex tube 2 this moment, the high temperature air that produces through vortex tube 2 preheats internal combustion generating set. The opening or closing of a valve arranged at a heat medium outlet of the heat exchanger 3 can also be controlled by a controller, the valve is controlled to be closed when the internal combustion engine generator set is not started, and the valve is controlled to be opened after the internal combustion engine generator set is started.
