Abstract

The utility model provides an automobile air conditioner heating system, which comprises a heater module, an air blower and a PTC (positive temperature coefficient) auxiliary heating module, wherein the air blower and the PTC auxiliary heating module are respectively positioned at two sides of the heater module. The automobile air conditioner heating system has the advantages that on one hand, the heat of the traditional engine is also utilized, on the other hand, a PTC thermistor is adopted as a body, the heat is generated through the low-voltage and heavy-current excitation, the temperature of cooling water of the engine is firstly absorbed through the air supply effect of the air blower, then, hot air at the part is used for further raising the temperature of heated air through the PTC thermistor, the air is heated for raising the temperature in an automobile, and the warm and comfortable automobile seating environment is created for passengers.

Description

A kind of air conditioning for automobiles heating system

Technical field

The utility model relates to the automotive air-conditioning system field, is specifically related to a kind of air conditioning for automobiles heating system.

Background technology

Automotive air-conditioning system is mainly used in vehicle in summer or carries out the regulating action of indoor temperature, humidity winter, mainly is comprised of three sub-systems: refrigeration system, heating system, air exchange system; Wherein refrigeration system mainly utilizes the material physical change to produce low temperature; Heating system mainly heats with the heat that the driving engine operation produces; Air exchange system mainly uses blower fan and air door to realize the airiness that Che Neiche is outer, and wherein refrigeration system comprises: the parts such as compressor, evaporator, blowing engine, condenser, pipeline form; Heating system comprises: the component parts such as temperature booster, blowing engine, warm braw pipeline; Air exchange system comprises: the parts such as blowing engine, inside and outside air door form.

automotive air-conditioning system has been a part important in present Full Vehicle System, the passenger is provided comfortable environment by bus, heating system is used very frequent in the winter time, guarantee the snugness of environment by bus, but due to this system heat sources mainly from the cooling water expansion tank of driving engine, so the quality of this system effect is directly relevant with the temperature of engine cooling water, the temperature of engine cooling water is low causes the winter heating effect bad, vehicle interior temperature is low to the sensation of passenger with cold, but general very low 2/3rds left and right of usually only having gasoline car of temperature due to present diesel oil vehicle cooling water expansion tank, therefore it is not fine causing the heating system of diesel oil vehicle, out of reach user operating needs.

The utility model content

For the low insurmountable problem again of present diesel-powered vehicle cooling water expansion tank water temperature, the utility model provides a kind of air conditioning for automobiles heating system, can guarantee can guarantee that also heating system satisfies user's operating needs when Engine Coolant Temperature is low.

In order to realize the purpose of this utility model, concrete technical scheme is as follows:

A kind of air conditioning for automobiles heating system comprises heater module, blowing engine and PTC auxiliary heating module (posistor), and described blowing engine and PTC auxiliary heating module lay respectively at the both sides of heater module.

Preferably, described PTC auxiliary heating module is composed in parallel by the posistor more than 1.Preferred, described PTC auxiliary heating module is composed in parallel by 3 posistors.

Preferably, described PTC auxiliary heating module is controlled its open and-shut mode by air-conditioner controller.

The beneficial effects of the utility model:

The utility model is still used the heat of traditional driving engine on the one hand, adopting on the other hand a kind of posistor (PTC) is body, produce heat under excitation by low voltage, large electric current, air-supply effect by blowing engine first with the temperature absorption of engine cooling water then the hot blast of this part pass through again the temperature that posistor (PTC) further promotes heated air, heat the air-lift unit vehicle interior temperature, for the passenger builds a cosy environment by bus.

Number in the figure is as follows:

Heater module 1, blowing engine 2, PTC auxiliary heating module 3, posistor 31, heater core 11.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

As shown in Figure 1, 2, 3, a kind of air conditioning for automobiles heating system comprises heater module 1, blowing engine 2 and PTC auxiliary heating module 3(posistor), described blowing engine 2 and PTC auxiliary heating module 3 lay respectively at the both sides of heater module 1.Described heater module 1 comprises heater core 11.

In one embodiment, described PTC auxiliary heating module 3 is composed in parallel by the posistor 31 more than 1.In another embodiment, described PTC auxiliary heating module 3 composes in parallel (as shown in Figure 3) by 3 posistors 31.

As shown in Figure 4, air-conditioner controller receives the signal from cooling-water temperature sensor and outdoor temperature sensor, afterwards in the situation that given parameter in advance, controls the open and-shut mode of a plurality of posistors 31 that described PTC auxiliary heating module 3 comprises.

In one embodiment, the relatively impact of PTC auxiliary heating module 3 open and close states on whole heating system.As shown in Figure 5, hot engine water enters in heater core 11 by water inlet A, through flowing out hot device core body 11 from water outlet B after circulation; And the cold wind that blowing engine 2 blows out first once heats through heater core 11, and then carries out post bake through PTC auxiliary heating module 3.By experimental result table 1 data as can be known, heal differential under PTC auxiliary heating module 3 open and close states is respectively between 4 ~ 8 degrees centigrade in defroster and pin air port, the experimental result sufficient proof air conditioning for automobiles heating system of the present utility model greatly improved the low problem of present diesel-powered vehicle cooling water expansion tank water temperature.

Table 1 is stand test data of the present utility model

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
