And electrically connect several heater elements of setting.
Formed preferably, the flexible heat-conducting plate is bonded by least two sheets of flexible heat-conducting layer, each heater element is set
It is placed between flexible heat-conducting layer described in arbitrary neighborhood.
Preferably, the heating tape also includes inside the flexible heat-conducting plate and stretches out the confession being connected on power supply
Electric wire, each heater element electrically connect setting with the supply lines inside the flexible heat-conducting plate.
Preferably, several parallel branches are provided with the supply lines, if being provided with each parallel branch
The heater element of dry series connection.
Preferably, the supply lines includes zero line and live wire, the parallel branch is connected in the zero line and fire
Between line.
Preferably, the supply lines also includes being connected the ground wire set with each heater element.
Preferably, each adjacent heater element is distributed in the flexible heat-conducting plate with identical spacing.
Preferably, the head and the tail of the flexible heat-conducting plate are provided at both ends with and heating tape are wrapped on by heat tracing equipment
Detachable connecting device.
Preferably, the detachable connecting device is elastic adjustable fixed card buckle.
Present invention also offers a kind of shell and tube exchanger, including several packages and parcel are arranged at each package
On heating tape, the heating tape is above-mentioned heating tape provided by the invention.
Technical solution of the present invention, have the following advantages that：
Heating tape provided by the invention, including flexible heat-conducting plate and several heater elements, and due to flexible heat-conducting plate
Uniform fold makes to be heated evenly by heat tracing equipment so that more accurate by the detection temperature of heat tracing equipment on by heat tracing equipment.
Heating tape provided by the invention, in addition to positioned at the flexible heat-conducting plate inside and stretch out the confession being connected on power supply
Electric wire, each heater element electrically connect setting, therefore each heating with the supply lines inside the flexible heat-conducting plate
Element common power supply line, avoid in the prior art each each heater element be intended to that supply lines is independently connected, so as to reduce
Outside cabling, production efficiency is improved, reduce error rate.

The required accompanying drawing used is briefly described in embodiment or description of the prior art, it should be apparent that, in describing below
Accompanying drawing is some embodiments of the present invention, for those of ordinary skill in the art, before creative work is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation after the heating tape expansion that embodiments of the present invention provide；
Fig. 2 is the structural representation after the heating tape installation that embodiments of the present invention provide；
Fig. 3 is the attachment structure schematic diagram of each heater element in the heating tape that embodiments of the present invention provide.
Embodiment
Technical scheme is clearly and completely described below in conjunction with accompanying drawing, it is clear that described implementation
Example is part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
In the description of the invention, it is necessary to explanation, term " " center ", " on ", " under ", "left", "right", " vertical ",
The orientation or position relationship of the instruction such as " level ", " interior ", " outer " be based on orientation shown in the drawings or position relationship, merely to
Be easy to the description present invention and simplify description, rather than instruction or imply signified device or element must have specific orientation,
With specific azimuth configuration and operation, therefore it is not considered as limiting the invention.In addition, term " first ", " second ",
" the 3rd " is only used for describing purpose, and it is not intended that instruction or hint relative importance.In addition, invention described below
As long as involved technical characteristic does not form conflict can and be combined with each other each other in different embodiments.
As shown in Figure 1 to Figure 3, the heating tape that the present embodiment provides, including flexible heat-conducting plate 1, are encapsulated in the flexibility and lead
In hot plate 1 and several heater elements 2 of setting are electrically connected, electricity is connected to positioned at the flexible inside of heat-conducting plate 1 and stretching
