The invention relates to a heating engineer vehicles, cha is tiny heating system cab trucks in which the heater that heated the air in the cabin, uses the heat of the coolant of the vehicle engine, the heat of exhaust gases of the engine or auxiliary heater (French patent N 2433428, CL 60 N 1/00, from 22.06.79, and.with. USSR N 1505803, 60 N 1/18, 07.09.89).The drawback of such heating systems is that during the stop of the vehicle for the rest of the driver to maintain the desired temperature in the cabin, the ongoing operation of the motor vehicle or auxiliary heater.Also known heating systems of vehicles, in which the heat of exhaust gases of the vehicle or engine coolant is accumulated in a special tank filled with liquid coolant (patent Germany N 3344484, CL 60 N 1/02, 06.12.83, and.with. THE USSR 1020263, 60 N 1/04, 30.05.83).During the car Parking this tank gives off heat, heating a car.However, supply tanks because of their bulkiness cannot be installed in the cab of the vehicle, including sleeping on the driver's seat. In addition, the cab trucks usually reverse-hinged (for inspection of the engine), so setting tanks with liquid accumulating substance is undesirable because of the possibility of podekorstroy for vehicles with engine equipped with a crankcase filled with lubricating oil, macropolicies pump, oil line, the main heat exchanger containing an additional heat exchanger disposed in the cabin of the vehicle included in the oil line of the engine in series with the main heat exchanger 
This heating device ensures good heating of the vehicle cabin, as is used as coolant, the lubricating oil of the engine, which has a higher heat capacity than the water used in the previously described devices. However, the heating system operates only when the engine is running. With the engine stopped because of cooling fluid (lubricating oil) temperature in the cabin of the car is reduced, although more slowly than in the devices, where water is the coolant from the cooling system of the engine.The present invention is to provide a reliable, convenient devices that maintain the normal temperature in the cabin of the vehicle in winter conditions during a stop without turning on the engine or other heat sources.In the heating device to transport the Noi highway and the main heat exchanger, contains additional heat exchanger disposed in the cabin of the vehicle and included in the oil line of the engine, according to the invention, the additional heat exchanger is a coil placed on the bed of the driver inside the monolithic plate-battery, made from a material having a high heat capacity, such as concrete or other composite material.Inlet and outlet piping to the additional heat exchanger can be equipped with vertical creases above the level of plate-battery respectively at the input and output of the additional heat exchanger.In addition, tube heat exchanger coil may be connected by a metal grid plate, the battery may be installed on a strip of material with low heat conductivity, for example of felt, and between the plate pack and the strip can be laid foil.The extra heat exchanger sleeping on the driver's seat inside a monolithic plate-battery, made from a material having a high heat capacity, such as concrete, helps maintain normal temperature in the cabin, to create comfortable conditions for ottem mode thermal energy of the heated oil is accumulated in the area of the bed of the driver and persists for a long time without turning on the engine or other heat sources which guarantees the safety of the driver from poisoning exhaust gases, saves the life of the engine, saves fuel.Such a plate can be safely installed on vehicles with tilting cab, leakage is excluded. With the engine switched off due to the presence of vertical creases on the inlet and outlet pipelines of the additional heat exchanger oil is not drained, and remains in the coil and providing additional heating of the plate.The connection of the coil tubes metal mesh improves the distribution of heat from the coil and the heat dissipation plate of the battery. Setting the plate on a layer of material having low heat conductivity (felt) reduces heat loss to the environment, and the introduction of a layer of foil between the stove and felt in addition to reducing heat loss to the environment due to the reflection it provides additional heating plates that reflected the warmth.Thus, the proposed device provides a relatively long maintenance of normal conditions in the driver's cab in the cold season when the engine is switched off. The design is convenient in operation, excluded leakage and the possibility of poisoning the driver in the of tipa and known analogues and should not be explicitly studied the prior art, therefore, the authors believe that the object is new and involves an inventive step.The inventive device can be widely used in road transport, i.e., it is industrially applicable.In Fig.1 shows a diagram of a device for heating the vehicle cabin, is connected to the lubrication system of the engine; Fig.2 a cross-section of the heating device.The device for heating the vehicle cabin is included in the lubrication system of an internal combustion engine provided with a crankcase 1, is filled with lubricating oil, macropolicies pump 2 (radiator section), oil line 3 with the main heat exchanger 4 (oil cooler) and a drain pipe 5. The device for heating the vehicle cabin includes an additional heat exchanger coil 6, is placed on the bed of the driver inside the monolithic plate of the battery 7. With the engine lubrication system additional heater coil 6 is connected by piping (inlet 8 and outlet 9), which have vertical creases 10 and 10' above the level of plate-battery 7 respectively on the inlet and outlet of the supplementary heat exchanger 6.In the supply line is provided from the coil 6. At the bottom of the heat exchanger coil mounted tube 12 to drain the oil.After macropodoidea pump (radiator section) 2 set the filter 13 and thermostat 14, the directional flow of oil to an additional 6 and 4 main heat exchangers or through the bypass channel 15 on plums.The valve 16, the cab heater located in the vehicle cabin, directs the oil to the additional heat exchanger 6 or radiator (the main heat exchanger) 4.At the entrance to the heat sink (the main heat exchanger 4 has a valve 24 off the radiator at very low temperatures, guide the lubricating oil to drain through the bypass pipe 17.Tube heat exchanger coil 6 is connected with the external and internal sides of the metal grid 18 (heat shield). Stove-battery 7 is installed on the gasket 19 of a material having low thermal conductivity (insulator) such as felt. Between the plate 7 and the gasket 19 is laid foil 20 (for directional heat radiation). Plate 7 to heat exchanger coil 6 is installed in the recess of the bed and fixed by bolts 21 to the bottom 22 of the bed through the reinforcing plate 23. The bottom of the bed again.The lubricating oil supplied macropolicies pump (radiator section) through the suction pipe 3 is filled with lubricating oil in the crankcase 1 of the engine, flows into the oil filter 13, and then thermostat 14. If oil temperature is below 80aboutWith, the oil is drained into the sump through the bypass channel 15. If the oil temperature is above 80aboutWith, the oil is directed to the heating of the cabin to the faucet 16 heater. In the warm time of the valve is blocked and the oil is supplied to the radiator 4. In the cold season through the open valve 16 oil supply pipe 8 through the bend it enters the heat exchanger coil 6 and gives off heat plate-battery 7. Then gave the heat the oil through the discharge pipe 9 is returned into the oil line of the engine, passes through the radiator 4 and the drain pipe 5 enters the crankcase 1.When you stop the vehicle and shut off the engine hot oil remains trapped in the coil of the additional heat exchanger 6. Hot plate-battery 7 for a long time (5-7 h) slowly cools, giving up its heat in the cabin of the vehicle and, in particular, without heating the sleeping place of the driver.Thus, the proposed consensus heated cabins not only during movement of the vehicle, but in the long campsites driver. 1.
