Abstract
The utility model discloses a compound PTC heater of copper aluminium, including the copper tubing, aluminum alloy shell has been cup jointed in the outside of copper tubing, and the equal welded connection in both ends of copper tubing has the external thread joint, fixed mounting has the sensor interface on the pipeline section of copper tubing, the equal fixedly connected with fixed plate in both sides of external thread joint, and seted up the internal thread fixed orifices on the fixed plate. The utility model discloses simple structure is showing the heat exchange efficiency and the corrosion resisting property that have improved the heater, has reduced the processing cost simultaneously, has strengthened sealed effect, has also made things convenient for the installation of heater fixed, and the practicality is strong.
Description
Technical Field
The utility model relates to a heating element technical field especially relates to compound PTC heater of copper aluminium.
Background
The PTC heater has the constant temperature heating characteristic, and the principle is that after the PTC heating sheet is electrified, the resistance value is increased by self-heating to enter a jump zone, the surface temperature of the PTC heating sheet keeps a constant value, the temperature is only related to the Curie temperature and the applied voltage of the PTC heating sheet and is basically unrelated to the ambient temperature, and even under the condition of abnormal work, the input power can be reduced very low due to the self-regulation action of the PTC element, so that the accident condition can not be generated.
However, the current heater is formed by extruding industrial aluminum profiles 6063-t5, the internal aluminum profile is a liquid medium channel, the heat conductivity coefficient of the 6063-t5 aluminum profile is 201W/m.K, the heat exchange effect is poor when liquid passes through, poor heat dissipation of a PTC element is caused, attenuation of devices is accelerated, the connecting part is mainly formed by turning the self aluminum profiles, internal threads or external threads are machined, raw materials are wasted, meanwhile, the machining process is increased, the connecting part needs to be changed, the tightness after connection is poor, a leakage test needs to be carried out, and the attractiveness is poor, so that the copper-aluminum composite PTC heater is provided.
Disclosure of Invention
The utility model aims at solving the defects existing in the prior art and providing a copper-aluminum composite PTC heater.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the copper-aluminum composite PTC heater comprises a copper tube, an aluminum alloy shell is sleeved on the outer side of the copper tube, external thread joints are welded at two ends of the copper tube, a sensor interface is fixedly mounted on a tube section of the copper tube, fixing plates are fixedly connected to two sides of the external thread joints, and internal thread fixing holes are formed in the fixing plates.
Preferably, the length of the copper tube is greater than that of the aluminum alloy shell.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses in through setting up copper tubing, external screwed joint, fixed plate and female thread fixing hole, utilize the copper tubing that coefficient of heat conductivity is 386.4W/m.K as the liquid medium passageway, increase heat exchange efficiency, and the corrosion resistance of copper tubing is good, more difficult incrustation scale that ties, has reduced the machining to the aluminium alloy simultaneously, and sealing performance is good, and it is convenient to install, and the in-service use is effectual.
To sum up, the utility model discloses showing the heat exchange efficiency and the corrosion resisting property that have improved the heater, having reduced the processing cost simultaneously, having strengthened sealed effect, also made things convenient for the installation of heater fixed, the practicality is strong.
