Description

A kind of Practical liquid ptc heater

Technical field

This utility model is related to heater, and in particular to a kind of Practical liquid ptc heater.

Background technology

Ptc heater is called PTC heaters, when having that intensification is rapid, meet power failure because of it can autocontrol temperature, use the longevity Life is long, be difficult spontaneous combustion, it is safe and reliable the features such as, especially in printed substrate（PCB）Industry and photovoltaic industry are used for plus hot liquid, The operation principle of ptc heater is：First it is powered and drives the heating of PTC fever tablets, heat to be transmitted to outside by heat conduction aluminium section bar Metal tube, metal tube adds hot liquid.The ptc heater of said structure is generally heated using single PTC fever tablets, because of PTC heatings When piece is heated, heat conduction aluminium section bar easily heats up dilatancy, causes PTC fever tablets fully can not contact with heat conduction aluminium section bar, no Heat can be effectively conducted, heats, and the heat conduction aluminium section bar reduction of service life for deforming is reduced, be can not meet actually used Need.

Utility model content

In order to the heats for solving existing ptc heater are bad, this utility model provides a kind of reasonable, convenient real Liquid ptc heater is used, concrete technical scheme is as follows：

A kind of Practical liquid ptc heater, including metal outer pipe, heat conduction aluminium section bar and PTC fever tablets, in metal outer pipe Heat conduction aluminium section bar is installed in portion, and heat conduction aluminium section bar has two and symmetrically, and placed cavity, placed cavity are provided with inside heat conduction aluminium section bar Inner side is provided with two symmetrical arc salient angles, and PTC fever tablets are placed on placement intracavity and prevent from walking by the clamping of arc salient angle, single Individual heat conduction aluminium section bar outside is provided with two projections, and four symmetrical distributions of projection prevent heat conduction aluminium section bar expanded by heating from deforming.

Used as another kind of preferred version of the present utility model, the PTC fever tablets external sheath has insulation sleeve.

Used as another kind of preferred version of the present utility model, the insulation sleeve top is provided with protection copper sheet, protects copper sheet Aluminum patch is installed in top, and aluminum patch contacts with placed cavity inside top.

Used as another kind of preferred version of the present utility model, the metal outer pipe is stainless steel tube or titanium tube or stainless steel tube Surface is set with Teflon.

Used as another kind of preferred version of the present utility model, the PTC fever tablets connect external electrical by lead electrode Source.

Used as another kind of preferred version of the present utility model, the PTC fever tablets are PTC-ceramic fever tablet.

Used as another kind of preferred version of the present utility model, the aluminum patch is by two pieces of mutually chimeric trapezoidal aluminum patch groups Into.

The beneficial effects of the utility model：When being heated using ptc heater of the present utility model, two arcs in placed cavity inner side Shape salient angle clamps PTC fever tablets, and PTC fever tablets will not walk and be fully contacted with heat conduction aluminium section bar, beneficial to conduction heat, heat conduction On the outside of aluminium section bar after expanded by heating, four symmetrical distributions of projection are arranged, and are conducive to mutually holding out against negative function power, heat conduction aluminium profiles Material will not deform, in addition, PTC fever tablet external sheaths have insulation sleeve, prevent PTC fever tablets from leaking electricity, and cause security incident.

Specific embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described further：

In description of the present utility model, it should be noted that term " " center ", " on ", D score, "left", "right", " perpendicular Directly ", the orientation or position relationship of the instruction such as " level ", " interior ", " outward " is, based on orientation shown in the drawings or position relationship, to be only For the ease of describing this utility model and simplifying description, rather than it is specific to indicate or imply that the position of indication or element must have Orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.

As shown in Figures 1 to 3, a kind of Practical liquid ptc heater, including metal outer pipe 1, heat conduction aluminium section bar 2 and PTC heating Heat conduction aluminium section bar 2 is installed in piece 3, the inside of metal outer pipe 1, and PTC fever tablets 3 connect external power source, heat conduction aluminum by lead electrode Section bar 2 has two and symmetrically, is provided with placed cavity 21 inside heat conduction aluminium section bar 2, the inner side of placed cavity 21 be provided with two it is symmetrical Arc salient angle 22, PTC fever tablets 3 are placed in placed cavity 21 to be clamped by arc salient angle 22 and prevent from walking, single heat conduction aluminium section bar 2 outsides are provided with two projections 23, and four symmetrical distributions of projection 23 prevent the expanded by heating of heat conduction aluminium section bar 2 from deforming.

Specifically, the external sheath of PTC fever tablets 3 has insulation sleeve 4, when insulation sleeve 4 prevents PTC fever tablets 3 from leaking electricity, outside metal Pipe 1 is powered to cause security incident, the top of insulation sleeve 4 to be provided with protection copper sheet 5, the protection protection PTC of copper sheet 5 fever tablets 3 and insulation Set 4 installs aluminum patch 6 from infringement, the top of protection copper sheet 5, and aluminum patch 6 contacts with the inside top of placed cavity 21, preferably folder Close contact PTC fever tablet 3, is easy to heat transmission.
