Abstract
The utility model relates to an additionally-installed air-side PTC heater of a diesel saloon car, which is characterized in that the PTC heater is composed of the heater and a bracket, and the heater is arranged on the bracket and is assembled on warming and defrosting air flues. The PTC heater has the functions of defrosting and quick warming, and solves the problems of cold-start defrosting and slow warming of diesel vehicles; the PTC heater adopts constant-temperature heating, open fire does not completely exist, and the PTC heater can automatically control the temperature when malfunction is incurred at a blower, and can cut off power supply at proper time; the installation is simple and convenient, the PTC heater is directly assembled on the air flue, the changing of the vehicles is less, and the like.
Description
Technical field
The utility model belongs to the technical field of sedan air conditioner, and particularly a kind of diesel-powered car installs wind side ptc heater additional.
Background technology
Because of passenger car diesel has the advantage of high efficiency, low emission,, has boundless development space so the diesel oil degree of world's car improves constantly in recent years.Because diesel engine hot merit conversion efficiency height, it is just few to produce used heat like this, and the defrosting of air conditioning for automobiles and heating system utilize the used heat of engine to warm oneself exactly.So most diesel-powered car all exists defrosting and the slow problem of heating speed.
Summary of the invention
The utility model purpose provides a kind of diesel-powered car and installs wind side ptc heater additional.
The technical solution of the utility model is achieved in that
Diesel-powered car installs wind side ptc heater additional, it is characterized in that: it is made up of heater, support, and heater is rack-mount, is assemblied on heating and the defrosting duct.
The utlity model has defrosting, heating rapidly, solved diesel vehicle cold start-up defrosting and the slow problem of heating speed; Heated at constant temperature can also be cut off the electricity supply by autocontrol temperature when the safe flames of anger, chance fan trouble in good time; Characteristics such as simple installation directly is assemblied on the air channel, and the vehicle change is little.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structural representation of the present utility model.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Diesel-powered car installs wind side ptc heater additional, it is characterized in that: it is made up of heater 1, support 2, and heater 1 is installed on the support 2, is assemblied on heating and the defrosting duct 3.
As depicted in figs. 1 and 2, the utility model has selected that thermal resistance is little for use, heat exchange efficiency is high and the long-term low PTC ceramic heater of power attenuation that uses as heating element heater, be assemblied on heating and the defrosting duct, by the heat insulation aluminium brackets in part, guarantee heat can not be delivered to the air channel in a large number and make its temperature distortion, so just form wind side PTC auxiliary heater.
One, stand is investigated test
1, ptc heater is driven by the truck batteries of two 120Ah, and air blast is powered by voltage-stabilized power supply.The air channel is installed additional ptc heater, and leaving air temp is measured, test data such as following table:
Conclusion (of pressure testing):
(1) as long as wind is arranged through heater, defrosting duct just can not melted by heater; If there is not wind to pass through, defrosting duct is by the very fast fusing of heater.
(2) behind the startup ptc heater, leaving air temp improves 2.2 ℃-4 ℃.
2, examine or check the PTC heating power with change of wind velocity, test data such as following table:
The PTC heating power changes test with wind speed
| The air blast wind speed | Fin surface temperature peak (C) | PCT both end voltage (V) | By PCT electric current (A) | Power (W) |
| 1 grade | 61 | 12.1 | 10.1 | 122.21 |
| 4 grades | 38 | 12.1 | 17.8 | 215.38 |
Test data shows that the PTC heating power also has corresponding variation with change of wind velocity, for electrical design such as wire harness, fuse provide reference.
Two, control strategy: carry out control strategy design and related components transformation according to investigating result of the test.
(1) only under the situation that air blast is opened, just allows the startup ptc heater.Electric control circuit is carried out corresponding transformation, only realized after the adhesive of air blast relay, just connecting ptc heater supply line, prevent that effectively the air channel is heated fusing under calm situation.
(2) behind the vehicle launch in winter, can start wind side auxiliary heater at once, improve wind-warm syndrome, guarantee defrosting and heating.When car indoor temperature and coolant temperature reached a numerical value, controller can stop auxiliary heater work, and utilizes engine waste heat to warm oneself.
Three, car load defrosting test is investigated
Experimental condition:
According to rules " performance requirement and the test method of the defrosting of GB11556-94 automobile air window glass " requirement.
Test site: cold-test chamber
Conclusion (of pressure testing):
1. press front windshield 90% area defrost relatively: former when automobile-used about 17.5 minutes; Install about 13.5 minutes of ptc heater system time spent additional.After little red flag diesel vehicle car installed wind side ptc heater additional, defrosting effect was significantly better than former car.
2. after installing ptc heater additional on the heating air channel, wind-warm syndrome rising speed is fast, can solve diesel vehicle cold start-up defrosting and the slow problem of heating speed effectively.
Claims (2)
1, diesel-powered car installs wind side ptc heater additional, it is characterized in that: it is made up of heater (1), support (2), and heater (1) is installed on the support (2), is assemblied on heating and the defrosting duct (3).
2, diesel-powered car according to claim 1 installs wind side ptc heater additional, it is characterized in that: described heater (1) is a ptc heater.
