Description

A kind of fresh air system special intelligent temperature-adjusting type PTC heaters

Technical field

PTC technical fields are the utility model is related to, are specially a kind of fresh air system special intelligent temperature-adjusting type PTC heaters.

Background technology

Heated at constant temperature PTC thermistor has constant temperature warming characteristic, its principle is self-heating heating after PTC thermistor power-up Resistance value is set to enter transition area, heated at constant temperature PTC thermistor surface temperature will keep constant value, and the temperature is only electric with PTC temperature-sensitives The Curie temperature of resistance is related with applied voltage, and is exactly to utilize heated at constant temperature with the substantially unrelated .PTC heating elements of environment temperature The heating element part of PTC thermistor constant temperature warming characteristic design heats occasion in middle low power, and PTC heating elements have perseverance Warm fever, the flames of anger, thermal conversion rate is high, it is incomparable to be influenced the conventional heating elements such as minimum, natural life-span length by supply voltage Advantage, application in electric heating appliance increasingly favored be subject to research and development engineer.

Heated at constant temperature PTC thermistor can be fabricated to various shapes structure and different size, common are disc, rectangular The such as shape, strip, annulus and honeycomb cellular, which are combined above-mentioned PTC heater elements and hardware, can form respectively The High-Power PTC heating element of kind form.

At present, the heater element installed in fresh air system, poor safety performance, service life are short.

Utility model content

The purpose of this utility model is to provide a kind of fresh air system special intelligent temperature-adjusting type PTC heaters, with solution State the problem of being proposed in background technology.

To achieve the above object, the utility model provides following technical solution：A kind of fresh air system special intelligent temperature-adjusting type PTC heaters, including left socle, right support and PTC sub-assemblies, the PTC sub-assemblies both ends are fixed by fixed screw respectively Connection left socle and right support, the PTC sub-assemblies are arranged in parallel between left socle and right support, two neighboring PTC combinations Aluminum fin-stock is set between part, and the right support surface is fixedly installed integrated treatment part and temperature controlling chip, the integrated treatment part Fuse is connected respectively with temperature controlling chip, and the PTC sub-assemblies are also associated with lead-out wire.

Preferably, the lead-out wire includes sandwich layer, and fluorocarbon polymer nanometer layer, the fluorine carbon poly are set on the outside of the sandwich layer Fiberglass braided layer is set on the outside of compound nanometer layer, polyester film band is coated on the outside of the fiberglass braided layer, it is described poly- Cladding restrictive coating on the outside of ester film band；The restrictive coating uses outer jacket made of low-smoke halogen-free polyolefin flame-proof material.

Preferably, the temperature controlling chip uses integrated temperature control chip LM56.

Preferably, the PTC sub-assemblies are vertically arranged with aluminum fin-stock.

Compared with prior art, the beneficial effects of the utility model are：

(1) the utility model is simple in structure, can realize automatically controlling for temperature, have a safety feature；In addition, what is used draws Outlet has high temperature resistant, fireproof performance, further increases the security performance of PTC heaters.

(2) in the utility model, aluminum fin-stock is set between two neighboring PTC sub-assemblies, using this structure, it is possible to increase PTC heater heat dissipation performances, further extend its service life.

Embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained, shall fall within the protection scope of the present invention.

- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of fresh air system special intelligent temperature-adjusting type PTC Heater, including left socle 1, right support 2 and PTC sub-assemblies 3,3 both ends of PTC sub-assemblies are solid by fixed screw 4 respectively Surely left socle 1 and right support 2 are connected, the PTC sub-assemblies 3 are arranged in parallel between left socle 1 and right support 2, two neighboring Aluminum fin-stock 5 is set between PTC sub-assemblies 3, and PTC sub-assemblies 3 are vertically arranged with aluminum fin-stock 5, using this structure, it is possible to increase PTC Heater heat dissipation performance, further extends its service life；2 surface of right support is fixedly installed 6 He of integrated treatment part Temperature controlling chip 7, temperature controlling chip 7 is using integrated temperature control chip LM56；The integrated treatment part 6 and temperature controlling chip 7 connect molten respectively Disconnected device 8, the PTC sub-assemblies 3 are also associated with lead-out wire 9.

In the utility model, lead-out wire 9 includes sandwich layer 10, and the outside of sandwich layer 10 sets fluorocarbon polymer nanometer layer 11, The outside of fluorocarbon polymer nanometer layer 11 sets fiberglass braided layer 12, and the fiberglass braided outside of layer 12 cladding is poly- Ester film band 13, the outside of the polyester film band 13 cladding restrictive coating 14；The restrictive coating 14 is hindered using low-smoke halogen-free polyolefin Outer jacket made of fuel；The lead-out wire of use has high temperature resistant, fireproof performance, further increases the peace of PTC heaters Full performance.
