Abstract
The utility model relates to an automobile rapid defrosting warm air blower, and belongs to a vehicle passenger compartment special-purpose heating device, in particular to a defrosting warm air blower of which can not come form an automatic power device. The automobile rapid defrosting warm air blower comprises a warm air blower blast tube with the end part provided with a defrosting opening, and is characterized in that an electrical heating device is installed at the connecting part of the defrosting opening and the warm air blower blast tube in series, a PTC electric heating element is arranged in the electrical heating device, and a radiating fin is arranged at the outer surface of the PTC electric heating element. The utility model has the advantages that the heat efficiency is high, the heating up is fast, and the defrosting effect is good.
Description
Technical field
The utility model belongs to the special-purpose heating arrangement of vehicle passenger cab, specifically is that a kind of heat is not the defrosting heater unit from engine installation.
Background technology
The Defroster device for vehicle device in winter of prior art, majority is the heat that has utilized the vehicle motor cooling water expansion tank, be transported on the shield glass and defrost through the air-supply pipeline by a special fan, but it is slower that the cooling water temperature of existing automobile heats up, be difficult to remove fast the long-pending frost on the windshield, influence the sight line of navigating mate, thereby cause certain potential safety hazard.Particularly for farm vehicle and the low and middle-grade load carrying vehicle areas cold especially in the north, the long-pending frost on the Windshield also can have influence on normal traffic safety.How under the prerequisite that does not change existing vehicle defroster device, to realize the quickly defrosting of vehicle, become those skilled in the art problem demanding prompt solution.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and existing automotive fan heater has been carried out improved a kind of automobile quickly defrosting heater unit.This automobile quickly defrosting heater unit has heat efficiency height, quick heating, the advantage that defrosting effect is good.
The utility model is achieved through the following technical solutions:
Promptly designed a kind of automobile quickly defrosting heater unit, the heater unit blast pipe that comprises end installation defrosting mouth, it is characterized in that at defrosting mouth and heater unit blast pipe connection part bit string dress electric heater unit, the built-in PTC electric heating element of this electric heater unit, and radiating gill is set at the outside face of PTC electric heating element.
For strengthening the radiating effect of PTC radiating gill, can with above-mentioned heat sink design aluminium matter corrugated, net structure or other similar structures.
The beneficial effects of the utility model are: heat efficiency height, quick heating, defrosting effect are good.
Description of drawings
Below in conjunction with Figure of description the utility model is described in further detail:
Fig. 1: the utility model example structure scheme drawing.
Fig. 2: electric heater unit structural representation.
The specific embodiment
Before use, as shown in Figure 1 electric heater unit 2 is attached between the warm braw blast pipe 3 and defrosting mouth 1 of vehicle, and the positive and negative electrode of PTC electric heating sheets 9 in the electric heater unit 2 is linked to each other by power lead with the positive and negative electrode of Vehicle Power respectively.For ease of electric heater unit 2 is controlled, also can be in operator's compartment the installation and control switch, and this master cock linked to each other with power lead with conventional connecting mode.When starting vehicle in the winter time, because of the water temperature in the water tank 5 needs the long period to raise, so behind the drive motor 6 of the wind wheel 7 that has started former vehicle heater, open the master cock of PTC electric heating sheets 9 again and give the energising of PTC electric heating sheets.Because PTC electric heating sheets 9 has quick heating, heat is imitated high characteristics, and PTC electric heating sheets 9 outside face radiating gill 8 is set, radiating gill 8 can distribute the heat of PTC electric heating sheets 9 rapidly, so the wind of sending through wind wheel 7 blows out the heat that PTC electric heating sheets 9 produces by blast pipe 3 from defrosting mouth 1, the front windshield of vehicle is carried out quickly defrosting.For strengthening the radiating effect of PTC radiating gill 8, can with above-mentioned heat sink design aluminium matter corrugated, net structure or other similar structures.
After the water temperature in the vehicle launch certain hour water tank 5 raises, can close the master cock of PTC electric heating sheets 9, vehicle is normally defrosted or by heating in 4 pairs of operator'ies compartment of warm wind port with former heater.
Claims (3)
