Abstract
The utility model discloses an electric heating tube comprising an external metallic sleeve, a heating element, an insulating layer, a lead-out rod and sealant, wherein the heating element is arranged in the external metallic sleeve and in an inner wall clearance thereof, the lead-out rod connected with the heating element penetrates through the sealant sealing the end part of the external metallic sleeve, an insulating sleeve is sheathed on the lead-out rod exposed outside, the external metallic sleeve is in compact type, and the shape of the heating element is matched with the shape of the external metallic sleeve. The electric heating tube selects and uses the compact type external metallic sleeve, the shape of which is matched with the heating element, so that the heat radiation of the electric heating tube can be uniform and intensive, thereby greatly improving the heat conversion efficiency and saving about 35 percents of energy in comparison with the traditional electric heating tube; and simultaneously, the electric heating tube occupies small space and is convenient to be moved and installed.
Description
Technical field
The utility model belongs to the electric heating element technical field, particularly a kind of electrothermal tube.
Background technology
Electrothermal tube is to be made of heater, insulation filling material and metallic sheath pipe and lead-out wire, electrothermal tube in-built electrical resistance body is as heater, this electrothermal tube adopts the halogen tungsten fluorescent tube mostly, contain ultraviolet ray in the halogen tungsten fluorescent tube radiation spectrum, human eye is stimulated greatly, so the electric heater of considerable part adopts the NI-G wire coil to constitute electrothermal tube on the market.Electrothermal tube is made generally in the straight tube type, and this structure takes up room greatly, and thermal radiation is not concentrated, and thermal conversion efficiency is low.In addition, this electrothermal tube is easy to produce electric leakage and punch-through in use, makes metallic sheath pipe racks electricity, human electric shock's phenomenon may take place, the crisis personal safety.
The utility model content
The purpose of this utility model provides evenly concentrated, the safe and reliable electrothermal tube of a kind of thermal radiation.
For achieving the above object, the technical solution of the utility model is: a kind of electrothermal tube, comprise outer metal sleeve, heater, insulating barrier, eduction rod and sealant, with its inwall gap heater is set in the outer metal sleeve, the eduction rod that connects heater passes the sealant that is sealed in outer metal sleeve end, be exposed to outer eduction rod and be with insulating sleeve, described outer metal sleeve has compact pattern, and the heater build is complementary with outer metal sleeve build.
Gap between described outer metal sleeve inwall and the heater is provided with inner metal shield, is filled with insulating barrier between outer metal sleeve, inner metal shield and the heater three.
The end of described outer metal sleeve is arranged with adapter sleeve.
Described eduction rod outer end is connected with the interface nose.
Outer metal sleeve of the present utility model is selected compact pattern for use, and heater build with it is complementary, and the electrothermal tube thermal radiation is evenly concentrated, and improves thermal conversion efficiency greatly, compares energy-conservation about 35% with the traditional electrical heat pipe; Simultaneously, electrothermal tube takes up room little, is convenient to carrying and installation.Gap between metal sleeve inwall and the heater is provided with inner metal shield outside, and is filled with insulating barrier, eliminates the static reaction, avoids electric leakage and punch-through take place, and use is safe and reliable.Be connected to the interface nose in the eduction rod outer end, make to install to become simpler and more direct, save time.
Description of drawings
Fig. 1 is the structural representation of the utility model U type electrothermal tube;
Fig. 2 is the schematic diagram of the utility model C type electrothermal tube.
Embodiment
Embodiment one, and electrothermal tube as shown in Figure 1 comprises outer metal sleeve 1, heater 2, insulating barrier 4, eduction rod 5 and sealant 6, and outer metal sleeve 1 is the compact pattern of U type, and thermal radiation is evenly concentrated, and improves thermal conversion efficiency.With its inwall gap heater 2 is set in the metal sleeve 1 outside, gap between outer metal sleeve 1 and the heater 2 is provided with inner metal shield 3, the build of heater 2 and inner metal shield 3 is complementary with the build of outer metal sleeve 1, be filled with insulating barrier 4 between metal sleeve 1, inner metal shield 3 and heater 2 threes outside, avoid producing electric leakage and punch-through, safe and reliable.The end of metal sleeve 1 is provided with sealant 6 outside, and the eduction rod 5 that heater 2 ends connect passes sealant 6, is exposed to outer eduction rod 5 outer cover and is provided with insulating sleeve 7.The outer end of eduction rod 5 is connected with interface nose 8, so that connection.The end of outer metal sleeve 1 is arranged with adapter sleeve 9, and it is solid and reliable that the utility model is cooperated.
Embodiment two, and as shown in Figure 2, be with the difference of embodiment one: the C type that outer metal sleeve 1, heater 2 and inner metal shield 3 are complementary for build, other structure are all identical with embodiment one.
The utility model is not limited to above-mentioned execution mode: outer metal sleeve 1 also can be for the cramped construction of other form, as circle, make simultaneously heater 2 and inner metal shield 3 with it build be complementary.
Claims (4)
1. electrothermal tube, comprise outer metal sleeve, heater, insulating barrier, eduction rod and sealant, with its inwall gap heater is set in the outer metal sleeve, the eduction rod that connects heater passes the sealant that is sealed in outer metal sleeve end, be exposed to outer eduction rod and be with insulating sleeve, it is characterized in that: described outer metal sleeve has compact pattern, and the heater build is complementary with outer metal sleeve build.
2. electrothermal tube as claimed in claim 1 is characterized in that: the gap between described outer metal sleeve inwall and the heater is provided with inner metal shield, is filled with insulating barrier between outer metal sleeve, inner metal shield and the heater three.
