Abstract
The utility model provides a cold and warm air device used for an electric vehicle, which can achieve the purposes of winter heating and summer cooling, is low in electricity consumption, and can enhance the driving capability of the electric vehicle and ensure the safe and reliable running of the complete device. The cold and warm air device comprises a warm air control switch and a cold air control switch, wherein the warm air control switch, and a direct current contactor and an electromagnetic relay which are connected in parallel are respectively in series connected between a first positive power terminal and a first negative power terminal, a normally-open contact of the direct current contactor and a PTC heating pipe are respectively in series connected between a second positive power terminal and a second negative power terminal, and a normally-open contact of the electromagnetic relay is connected with the cold air control switch in parallel and then in series connected between the first positive power terminal and the first negative power terminal with a fan. The cold and warm air device is suitable for medium-sized, small-sized and miniature electric vehicles.
Description
Technical field
The utility model belongs to control setup, particularly a kind of electronlmobil cold and warm air device.
Background information
Electronlmobil is to substitute oil with electric energy to substitute driving engine as a kind of environmental protection of power resources, the energy-conservation vehicle as energy source, electrical motor.Warm braw is time heating and the defrosting device that is absolutely necessary for winter driving, the heating of electronlmobil and the heating mode of traditional fuel-engined vehicle are different, the heating of traditional fuel-engined vehicle is a heat of using cycle of engine water, by blower fan the heat of water is dispelled in the car and to warm oneself, and the type of cooling of the motor of electronlmobil has some employings is natural air cooled, and the heat that produces in the time of therefore can't collecting machine operation is warmed oneself.In addition, electronlmobil all adopts air-conditioning to freeze, and the power consumption height influences the ability that electronlmobil continues.
The utility model content
The technical problems to be solved in the utility model provides and can realize a kind of winter heating, summer can realizing cooling, and power consumption is low, can improve the electronlmobil ability that continues, and guarantees the electronlmobil cold and warm air device that whole device is safe and reliable to operation.
The electronlmobil cold and warm air device that the utility model provides, comprise warm braw master cock 5 and cold wind master cock 6, described warm braw master cock 5 is connected between the first positive- negative power end 9,10 with DC contactor 2 and electromagnetic relay 4 in parallel, the open contact 2-1 of described DC contactor 2 and PTC heat-generating pipe 1 are connected between the second positive-negative power end 7,8, and the open contact 4-1 of electromagnetic relay 4 is connected between the first positive- negative power end 9,10 with cold wind master cock 6 backs in parallel and blower fan 3.
The utility model has the advantages that: easy to use by the control of changes in temperature switch, can realize heating and the interior needs of lowering the temperature of car in summer in the electronlmobil car in winter.Adopt winter the PTC heat-generating pipe to heat, according to the height of ambient temperature, the automatically regulating horsepower output, the effect that under the situation that ambient temperature raises, has high temperature rise resistance reduction horsepower output, can reduce degradation of energy, energy saving prevents the generation of dangerous situations such as calm dry combustion method; Adopt the contact of DC contactor can bear high potential, big electric current, guarantee that cold and warm air device is safe and reliable to operation; Start blower fan summer and can be used as small fan, play cooling effect, thereby realized the function of both cooling and heating.With respect to the power consumption of electronlmobil air conditioner refrigerating, saved most electric energy, therefore improved the ability that electronlmobil continues, be fit to use medium-sized, small-sized, miniature electric automobile.
Description of drawings
Fig. 1 is schematic circuit diagram of the present utility model.
Among the figure: PTC heat-generating pipe 1, DC contactor 2, open contact 2-1, blower fan 3, electromagnetic relay 4, open contact 4-1, warm braw master cock 5 is between cold wind master cock 6, the second positive-negative power ends 7,8, the first positive-negative power ends 9,10.
The specific embodiment
As shown in the figure, this electronlmobil cold and warm air device comprises warm braw master cock 5 and cold wind master cock 6, described warm braw master cock 5 is connected between the first positive- negative power end 9,10 with DC contactor 2 and electromagnetic relay 4 in parallel, the open contact 2-1 of described DC contactor 2 and PTC heat-generating pipe 1 are connected between the second positive-negative power end 7,8, and the open contact 4-1 of electromagnetic relay 4 and cold wind master cock 6 backs in parallel and blower fan 3 are connected between the first positive- negative power end 9,10.
During connection, the first positive- negative power end 9,10 connects the 12V direct supply, and the second positive-negative power end 7,8 connects the following direct supply of 360V, and present embodiment is an example to connect the 72V direct supply.During use, the open contact 2-1 adhesives of the closed control of warm braw master cock 5 DC contactor 2, PTC heat-generating pipe 1 heating of starting working, meanwhile, and the open contact 4-1 closure of electromagnetic relay 4, blower fan 3 is started working, and warm braw blows out; Cold wind master cock 6 closures, 3 work of control blower fan, cold wind blows out.When warm braw blew out, PTC heat-generating pipe 1, DC contactor 2, blower fan 3, electromagnetic relay 4 were worked simultaneously; When cold wind blows out, have only blower fan 3 to work independently.
Claims (1)
1. electronlmobil cold and warm air device, comprise warm braw master cock and cold wind master cock, it is characterized in that: described warm braw master cock is connected between the first positive-negative power end with DC contactor and electromagnetic relay in parallel, the open contact of described DC contactor and PTC heat-generating pipe are connected between the second positive-negative power end, the open contact of electromagnetic relay with after the cold wind master cock is in parallel and blower fan be connected between the first positive-negative power end.
