Description

A kind of tubular type liquid ptc heater

Technical field

This utility model belongs to PTC technical field of heating, is specifically related to a kind of tubular type liquid Ptc heater.

Background technology

In liquid heater field, PTC ceramic element has the characteristic of constant temp. warming, has The flames of anger, thermal conversion rate be high, affected minimum, length natural life-span, safety etc. by supply voltage has Point is the advantage that conventional heating element is incomparable.Such as, PTC-ceramic is capable of temperature certainly Control, on the one hand the connection for heater Yu electric wire reduces requirement, on the other hand different in appearance Reason condition, such as when water dryouies, the power of ptc heater can decline automatically, and surface temperature is only It is by fraction of rising, ptc heater will not be caused any damage；And electrothermal tube is due to nothing Method realizes temp autocontrolled, and after water dryouies, its surface temperature steeply rises, and can cause electrothermal tube Burn, even if under normal circumstances, due to the fluctuation of voltage, also its heating can be caused shadow Ring, shorten its service life.

At present, existing tubular-type PTC liquid heater, the both sides up and down of heater tube are arranged There are two aluminum pipes, are inside fixed with PTC sheet with realization for the heating of liquid in pipe, are heated liquid Body is from heater Bottomhole pressure, thus realizes heat exchange.Use the heater of above-mentioned this structure It is difficult to powerful heating, it is impossible to meet the routine use of people.

Therefore, a kind of powerful tubular type liquid ptc heater is needed badly.

Utility model content

In order to solve above-mentioned technical problem, this utility model provides a kind of tubular type liquid PTC Heater.

In order to achieve the above object, the technical solution of the utility model is as follows:

This utility model provides a kind of tubular type liquid ptc heater, including:

Aluminum pipe, aluminum pipe is the cylinder with preseting length, aluminum pipe axially arranged centrally along it There is fluid passage, the end face of aluminum pipe is provided with four for installing PTC along its circumferencial direction The mounting groove of calandria, the wall body of aluminum pipe is provided with between mounting groove multiple opening recessed Groove；

PTC calandria, it is arranged in mounting groove.

In this utility model, PTC calandria heats, and liquid flows through fluid passage and carries out heat exchange, Realize the heating of liquid, simple and reasonable, compared to the heater tube of same length, heating Power improves more than 1.5 times, it is achieved high-power heating, arranges open recess and aluminum pipe can be avoided to become Shape.

Wherein, above-mentioned PTC calandria includes PTC heating plate, insulating paper and two electrode slices, Electrode slice is respectively arranged at the upper and lower surface of PTC heating plate, electrode slice and PTC heating plate Integral coating is in insulating paper.

On the basis of technique scheme, also can do and improve as follows:

As preferred scheme, above-mentioned open recess is globoidal structure.

Using above-mentioned preferred scheme, open recess is globoidal structure, it is simple to processing.

As preferred scheme, above-mentioned fluid passage is waveform.

Using above-mentioned preferred scheme, fluid passage is waveform, increases liquid and fluid passage Contact area, improve the efficiency of heating surface.

As preferred scheme, aluminum wing is set in above-mentioned fluid passage.

Use above-mentioned preferred version, aluminum wing be set in fluid passage, form fluid flow paths, Make abundant heat exchange between liquid and aluminum wing, improve its power.

As preferred scheme, the surface of above-mentioned mounting groove is also coated with heat-conducting layer.

Using above-mentioned preferred scheme, the surface of mounting groove is also coated with heat-conducting layer, improves PTC The heat transfer of calandria, improves the efficiency of heating surface.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of embodiment of this utility model.

Wherein, 1. aluminum pipe, 2.PTC calandria, 3. fluid passage, 4. open recess.
