Background technology
Current different kinds of roads vehicle and the commonly used waste heat warm air system of engineering truck, this system utilizes the heat of engine cooling water for providing warm braw in driver's cabin.The problem of this system is under extreme low temperature weather conditions, and the temperature of engine cooling water rises slowly, is even difficult to rise to enough temperature, causes that warm braw effect is unsatisfactory for cab heating needs.Additionally it is configured with electric fan heater in the driver's cabin of a small amount of road vehicle and engineering truck, uses electric fan heater to warm oneself under extremely cold condition.But electrothermal hot air appts power is big, thus energy consumption is also high, and when being used alone electric warm-air machine, engine cool water resource is not utilized, it it is a kind of wasting of resources.
Summary of the invention
Present invention aims to the heating system of existing road vehicle and engineering truck only has big or that heating effect is not enough under the extreme low temperature environment problem of energy consumption in the hot-water heating heating system of electric heating heating system or engine cooling water heat supply, and provide a kind of and can fully warm oneself under extreme low temperature environment and the cab heating system of energy efficient.
The technical scheme is that and be achieved in that: a kind of cab heating system of structure, including electro-heat equipment and the control device controlling heat-producing unit work, electro-heat equipment includes housing, housing has air inlet and air outlet, there is the air channel from air inlet to air outlet in housing, being provided with the pressure fan, the hot-water heating core body by engine cooling water heat supply and the electric heating core body by electrical energy drive that drive air to flow in air channel in air channel, hot-water heating core body and electric heating core body are arranged in order to air outlet direction at air inlet in air channel.In the present invention, heating system adopts two kinds of heat supplies, in common area, can adopt engine cooling water waste heat for supplying, and the air output controlling pressure fan by controlling device carries out sending in driver's cabin warm；Only can not being reached, by engine cooling water heat supply, the extremely cold area that heating requires, control device and also control the heating of electric heating core body, the caloric value strengthening heating system meets the heating requirement of driver's cabin.In the present invention, heating system adopts two kinds of heat supplies, makes full use of engine cooling water waste heat, adds again electric heating simultaneously, thus realizing heating system to be suitable for common area and extremely cold area, and effectively energy-conservation.
In cab heating system of the present invention, control device to include controller and be connected with controller for detecting that air port goes out the temperature sensor of air themperature, the heat supply cooling water control valve of hot-water heating core body, electric heating core body heating control unit be electrically connected with the controller respectively.
In cab heating system of the present invention, temperature sensor is arranged in housing, between electric heating core body and air outlet.
In cab heating system of the present invention, pressure fan electrically connects with described controller, controller control the air output of pressure fan.It is being used alone hot-water heating core body adstante febre, can pass through to control air output and control heating effect
In cab heating system of the present invention, the heater element of electric heating core body is semiconductor thermistor fever tablet.
In cab heating system of the present invention, the heater element of electric heating core body is made up of semiconductor thermistor fever tablet two pieces in parallel.
The present invention compared with prior art has the advantages that in the present invention, and heating system adopts two kinds of heat supplies, and in common area, the air output controlling pressure fan by controlling device carries out sending in driver's cabin warm；Only can not being reached, by engine cooling water heat supply, the extremely cold area that heating requires, control device and also control the heating of electric heating core body, the caloric value strengthening heating system meets the heating requirement of driver's cabin.In the present invention, heating system adopts two kinds of heat supplies to make full use of engine cooling water waste heat, adds again electric heating simultaneously, thus realizing heating system to be suitable for common area and extremely cold area, and effectively energy-conservation.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments is described.
As shown in Figure 1 to Figure 3, cab heating system in the present embodiment includes electro-heat equipment and controls the control device of heat-producing unit work, electro-heat equipment includes housing 4, housing has air inlet and air outlet, the air channel from air inlet to air outlet is formed in housing, the pressure fan 5 and the hot-water heating core body 3 by engine cooling water heat supply and the electric heating core body 2 by electrical energy drive that drive air to flow in air channel it is provided with in air channel, hot-water heating core body 3 and electric heating core body 2 are arranged in order to air outlet direction at air inlet in air channel, control device and include controller, it is connected for detecting that air port goes out the temperature sensor of air themperature with controller, the heat supply cooling water control valve of hot-water heating core body, the heating control unit of electric heating core body is electrically connected with the controller respectively.Temperature sensor 1 is arranged in housing 4, between electric heating core body and air outlet.Pressure fan is electrically connected with the controller, controller control the air output of blower, be used alone hot-water heating core body adstante febre, can pass through to control air output and control heating effect.The heater element of electric heating core body 2 is semiconductor thermistor fever tablet, is made up of semiconductor thermistor fever tablet two pieces in parallel, can individually control respectively at applicable electric heating core body adstante febre.In the present embodiment, heating system adopts two kinds of heat supplies, heating system whether reach desired value by the temperature that the temperature sensor of air outlet place detect and controlled whether to open the heating of electric heating core body by controller, electric heating core body is opened the air output of unlatching heating power, electric heating core body not adstante febre pressure fan of adstante febre and is reached the purpose of adjustment cabin temperature.In common non-extremely cold area, owing to ambient temperature is higher, extraneous air enters into through air inlet only needs a small amount of heat supply just can reach target set temperature in the electro-heat equipment in heating system, or engine cooling water temperature is higher, when can individually meet the requirement to driver's cabin heat supply, the temperature that now controller detects according to the temperature sensor of air outlet place controls the air output of pressure fan and carries out sending in driver's cabin warm；Only by engine cooling water heat supply can not reach heating require extremely cold area or electromotor operating its cooling water temperature is relatively low soon can not meet driver's cabin heating demand time, controller controls the air output of electric heating core body heating power and pressure fan according to the temperature that the temperature sensor of air outlet place detects, and meets the heating requirement of driver's cabin by the caloric value of the electric heating core body supplementary heating system hot-water heating core body of heating reinforcement.In the present embodiment, heating system adopts two kinds of heat supplies, makes full use of engine cooling water waste heat, is simultaneously introduced electric heating, thus realizing heating system to be suitable for common area and extremely cold area, and effectively energy-conservation.
