Technical Field

The application belongs to the technical field of heaters, and particularly relates to a detachable PTC semiconductor overcurrent and plug-in dual-purpose heater.

Background

At present semiconductor pipeline liquid electrical heating field, most of products all wrap up the laminating PTC heating sheet and heat at whole die sinking pipeline outer wall, this kind of heating method has a lot of drawbacks, because the PTC semiconductor is the slice, the heat-generating body is the heat of both sides release when ohmic heating, will cause the PTC heat-generating body on pipeline surface to expose in the air like this, inside liquid only obtains the heat of heating sheet one side, it is big to cause the loss of heating pipe heat energy, rate of heating is slow, thereby lead to energy-conservingly. And when using very big limitation, liquid need be in the pipeline internal recycle heating during the heating, can not directly insert and use in liquid, and the aluminium alloy heating pipe is very high to the quality requirement of liquid when using, and corrosion resistance is very poor, in case the aluminium alloy is corroded by liquid and wears, not only whole heater need be changed and cause use cost to rise but also can cause, the danger of electric leakage.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present application provides a detachable PTC semiconductor overcurrent and plug-in dual-purpose heater, in which the PTC semiconductor is mounted on the detachable end cap and does not contact with the inside of the outer tube, thereby avoiding the problems of low heating efficiency and poor safety of the conventional heater.

In order to solve the technical problem, the utility model discloses a detachable PTC semiconductor overflowing and inserting dual-purpose heater, which comprises an outer tube body, wherein one end of the outer tube body is provided with a water inlet, and the other end of the outer tube body is provided with a flanging; the end cover is fixed on the end cover of the flanging through a clamp, and the end cover is provided with a water outlet; and a PTC semiconductor welded to the end cap and embedded in the outer tube, and a wire end of the PTC semiconductor is exposed out of the end cap; wherein, the PTC semiconductor does not contact the inner wall of the outer tube body.

According to an embodiment of the present invention, the outer tube body is a 304 stainless steel tube.

According to an embodiment of the present invention, the PTC semiconductor is a red copper profile.

According to an embodiment of the present invention, the PTC semiconductor is disposed in a plurality of rows and columns, and is circumferentially arrayed on the end cap.

According to the utility model discloses an embodiment, wherein above-mentioned water inlet all sets up to the screw thread port with the delivery port.

Compared with the prior art, the application can obtain the following technical effects:

1) the PTC semiconductor of the red copper section can be well resistant to corrosion, and the service life is greatly prolonged.

2) The end cover can be freely disassembled, the using way of the product is greatly improved, and the end cover can be uniformly heated in static liquid after being disassembled.

3) The PTC semiconductor is immersed in the liquid without dead angles for heating, so that heat energy is fully transferred to the liquid, and the product does not need to be a heat preservation device.

4) Different powers are made according to customer requirements, if the arrangement number of the PTC semiconductors of the copper pipe section is increased by high power, the PTC semiconductors can be directly connected in series or in parallel by low power pipelines, and the expansibility is very strong.

Of course, it is not necessary for any one product to achieve all of the above-described technical effects simultaneously.
