Description
Technical Field
The utility model relates to a PTC heater, in particular to PTC heater of automatic control temperature belongs to refrigeration engineering technical field.
Background
The warm air system of the traditional automobile air conditioner adopts water heating type heat supply, namely, the heat of cooling liquid of an engine water tank is utilized to heat passing air flow through a heat exchanger, and then hot air is blown into a carriage by a fan to heat the air in the carriage. The advantage is make full use of engine water tank's heat energy, and the shortcoming needs just can heat the effect after the cooling liquid intensifies after the start-up, need connect engine water tank's business turn over pipe with warm braw water pipe moreover to still need be equipped with the switch of water valve control water pipe, the installation procedure is loaded down with trivial details, and in the cold area of weather seriously influences the normal performance of air conditioner heating function moreover.
Disclosure of Invention
In order to solve the technical problem that the existing engine water tank heats, the utility model provides an automatic temperature control PTC heater.
The utility model adopts the technical proposal that: the utility model provides an automatic PTC heater of control temperature, by the PTC heater, radiating fin and temperature control component constitute, the PTC heater includes metal heating plate and PTC pottery, the one end of metal heating plate is connected with electrode terminal, the PTC pottery is high temperature resistant composite ceramic and wraps up in the outward appearance of covering at the metal heating plate, radiating fin is high coefficient of thermal conductivity's aluminum alloy corrugated sheet and wraps up in the outward appearance of covering at the PTC pottery, temperature control component includes temperature controller and temperature sensor, temperature controller installs at control panel and temperature sensor connects at radiating fin, temperature controller passes through the connecting wire and connects temperature sensor.
The utility model has the advantages that: the temperature is quickly increased, the temperature can be automatically controlled when a fan fails, and the service life is long; the voltage adaptation range is wide, and the voltage adaptation range can be designed between 12V and 380V according to the requirements of the use environment; the design is convenient, the design can be freely carried out from low power to high power, and the appearance can also be designed according to the requirements of the use environment; the fuel is not burnt, and is safe and reliable; the aluminum sheet is installed compactly and quickly to heat, and the heat efficiency is higher; the health, environment-friendly and adhesive-free adhesive is healthier; the ultra-long durable non-oxidation has a service life of 6000 hours; the heat efficiency of the PTC heating element is as high as 99%.
Drawings
The present invention will be further explained with reference to the accompanying drawings:
fig. 1 is a schematic side sectional structure of the present invention.
In the figure, 1, a radiating fin, 2, a metal heating sheet, 3, PTC ceramics, 4, an electrode terminal, 5, a temperature sensor, 6 and a connecting wire.
Detailed Description
In the embodiment of fig. 1, a PTC heater capable of automatically controlling temperature comprises a PTC heater, a heat dissipation fin 1 and a temperature control element, wherein the PTC heater comprises a metal heating plate 2 and PTC ceramic 3, one end of the metal heating plate 2 is connected with an electrode terminal 4, the PTC ceramic 3 is high-temperature resistant composite ceramic and is wrapped on the outer surface of the metal heating plate 2, the heat dissipation fin 1 is an aluminum alloy corrugated plate with high thermal conductivity and is wrapped on the outer surface of the PTC ceramic 3, the temperature control element comprises a temperature controller and a temperature sensor 5, the temperature controller is installed on a control panel and the temperature sensor 5 is connected to the heat dissipation fin 1, and the temperature controller is connected with the temperature sensor 5 through a connecting wire 6.
Example (b): firstly, the temperature of a temperature controller is designed on a control panel, a power supply of a metal heating sheet 2 is connected, and the metal heating sheet 2 generates heat and emits the heat outwards through PTC ceramics 3 and radiating fins 1.
