Description
Technical field
The utility model is related to a kind of electric heater, specifically a kind of PTC heat-generating pipes.
Background technology
Because the heating of PTC heater is rapid and noise is small, have a safety feature, multiple fields are applied to, such as water heater,
Pediluvium apparatus etc., but traditional this kind of PTC heater is that heat-conducting aluminium pipe is heated to the liquid, the gas that pass through in the outer part, it is single
The position time needs the rate-of flow heated greatly, and the thermal efficiency is low, and firing rate is slow.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of PTC heat-generating pipes, it can be rapidly heated and safe.
The utility model is achieved through the following technical solutions：A kind of PTC heat-generating pipes, including heat conducting pipe, PTC heating
Source, the heat conducting pipe offers cylindrical inner via hole at middle part and elongated accessibke porosity has been opened up in both sides, described
Set in inner via hole and set circumferentially distributed on the PTC pyrotoxins, the wall of the inner via hole in radiating core, the accessibke porosity
The outward flange of some grooves and the radiating core is set mutually to agree with.Heat conducting pipe uses aluminum pipe.
Radiating core carries out heat transfer with heat conducting pipe, and heat is distributed, passed to by being needed inside heat conducting pipe by radiating core again
The media such as the liquid or gas of heating, than traditional medium directly heated by heat conducting pipe inside pipe, using distributed
Local heating, medium heats up faster, and the thermal efficiency is high.
Preferably, the radiating core offers the core of through hole and centered on core in divergent shape setting including middle part
Some flabellums, the medium channel of " V " shape is constituted between adjacent flabellum.Radiated by some flabellums of radiating core, total
Area of dissipation becomes big, and the media such as liquid, gas scatter and heated by flabellum, and firing rate is faster.
Preferably, the end of the flabellum is arc, the groove of the heat conduction inside pipe wall is arc, for flabellum
Terminal end shape is engaged.Arcuate end and groove contact surface are round and smooth, when radiating core is installed into heat conducting pipe inner via hole, flabellum with it is interior
Through-hole wall installs more smooth, and mutual damage degree is small.
The utility model takes above-mentioned corrective measure and carried out, and its advantage is notable：PTC pyrotoxins heat heat conducting pipe,
Increase radiating core in heat conducting pipe, by heat transfer, the heat transfer of heat conducting pipe is to radiating core, and radiating core again passes through heat many
The media such as individual flabellum heating liquid, gas, the rate of heat addition can lift 10% or so.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment 1；
Fig. 2 is the structural representation of radiating core；
Fig. 3 is the longitudinal sectional view of heat conducting pipe.
1 is heat conducting pipe in figure, and 101 be inner via hole, and 102 be accessibke porosity, and 103 be groove, and 2 be radiating core, and 201 be core,
202 be flabellum, and 3 be PTC pyrotoxins.
Embodiment
The utility model is further described in conjunction with the embodiments below against accompanying drawing：
Shown in reference picture 1, Fig. 3, a kind of PTC heat-generating pipes include heat conducting pipe 1, PTC pyrotoxins 3, and heat conducting pipe 1 is opened up at middle part
There is cylindrical inner via hole 101 and opened up in both sides in elongated accessibke porosity 102, inner via hole 101 and radiating core is set
2, set in accessibke porosity 102 on the PTC pyrotoxins 3, the wall of inner via hole 101 circumferentially it is distributed set some grooves 103 with
Mutually agree with the outward flange of the radiating core 2.
It is provided with the core 201 of through hole as shown in Fig. 2 radiating core 2 includes middle part and is set centered on core 201 in divergent shape
The medium channel of " V " shape is constituted between some flabellums 202 put, adjacent flabellum 202, the end of flabellum 202 is arc, heat conducting pipe
The groove 103 of 1 inwall is arc, is engaged for the terminal end shape with flabellum 202.
The media such as liquid, gas are passed through heat conducting pipe, due to the structure function of radiating core, by medium be distributed to two-by-two flabellum it
Between medium channel in, separately heated, the firing rate of medium can be improved.
Listed above is only specific embodiment of the utility model, it is clear that the utility model is not limited to above example.
All deformations that one of ordinary skill in the art directly can export or associate from the utility model disclosure, all should belong to
In protection domain of the present utility model.
