Description
Technical field
The utility model relates to insulation field of heat transfer, particularly high temperature resistantly, anti-to pierce through and PTC calandria insulating sleeve easy to assembly about a kind of.
Background technology
As Figure 1-3, heater is made up of PTC heater 01 and the heat transfer aluminum pipe 02 be sleeved on outside heater, wherein heater 01 is by the electrode slice 011 being arranged on both sides and the semistor be positioned between two cube electrode sheets, two cube electrode sheets 011 are connected with wire 012 and wire 013 respectively, heater 01 insert heat transfer aluminum pipe on jack 021 or jack 022 in; For avoiding conducting electricity between electrode slice and heat transfer aluminum pipe, conventional mode is the insulating sleeve be made up of polyimide film on heater outer surface cover.But in actual processing, engineer finds, because electrode slice is metallic article, its fringe region is difficult to invariably there is a little sharp burr, burr, and as easy as rolling off a log insulation-piercing sleeve pipe, causes the danger of electric leakage.
Utility model content
In view of this, the utility model, for solving the problems of the technologies described above, provides a kind of and high temperature resistantly, anti-to pierce through and PTC calandria insulating sleeve easy to assembly.
The purpose of this utility model is achieved through the following technical solutions:
A kind ofly high temperature resistantly, anti-to pierce through and PTC calandria insulating sleeve easy to assembly, for the electric insulation of PTC heater, described PTC calandria insulating sleeve in a tubular form, it comprises three-decker, described three-decker comprises cover inner tube layer, aluminium foil layer, cover outer tube layer from inside to outside successively, and described PTC calandria insulating sleeve one end is opened wide in hot-press sealed, the other end naturally by built-in glue.
Described cover inner tube layer and cover outer tube layer are all a kind of polyimide films containing high-temperature plastic, and described aluminium foil layer is with cover inner tube layer and overlap outer tube layer for be close to structure without glue full-contact; Described cover inner tube layer comprises one or more basal layer, described cover outer tube layer also comprises one or more basal layer, described basal layer is a kind of polyimide film containing high-temperature plastic, the composite bed that described aluminium foil layer comprises one deck aluminium foil or mixed by aluminium foil and polyimide film.
Described basal layer by shape as strip and be rotated into tubulose containing the polyimide film band of high-temperature plastic, described polyimide film strip edge is provided with glue-line.
Preferably, described cover inner tube layer comprises multiple basal layer, and described multiple basal layer is by the mutual full-contact laminating of glue; Described cover outer tube layer comprises multiple basal layer, and described multiple basal layer is by the mutual full-contact laminating of glue.
The utility model compared to the beneficial effect of prior art is:
With traditional, only have compared with insulating sleeve that single or multiple lift polyimides film casing makes, what the utility model provided high temperature resistant, anti-ly pierces through and PTC calandria insulating sleeve easy to assembly, there is three-decker, comprise cover inner tube layer, aluminium foil layer, cover outer tube layer from inside to outside successively, described high-temp .-resisting insulation sleeve one end is opened wide in hot-press sealed, the other end naturally by built-in glue.During use, fever tablet is aimed in one end that insulating sleeve opens wide, and insulating sleeve is enclosed within fever tablet outer surface, utilizes built-in aluminium foil layer, the integral rigidity of reinforced insulation sleeve pipe, effectively avoids the burrs on edges of electrode slice, burr insulation-piercing sleeve pipe and cause the phenomenon of electric leakage.
