Description
Technical field
This utility model relates to the collection skin heater of a kind of built-in collection skin pipe, belongs to electric-heating technology field.
Background technology
Kelvin effect is also known as " Kelvin effect ".When alternating current is by conductor, owing to induction effect causes conductor to cut
On face, CURRENT DISTRIBUTION is uneven, and nearer conductive surface electric current density is the biggest.This phenomenon claims " Kelvin effect ".Kelvin effect makes to lead
The effective resistance of body increases.Frequency is the highest, and Kelvin effect is the most notable.When the electric current that frequency is the highest passes through wire, it is believed that
Flowing through in only the thinnest in conductive line surfaces one layer of electric current, this cross section being equivalent to wire reduces, and resistance increases.Since wire
Core passes through almost without electric current, it is possible to this core is removed to save material.Therefore, can in high-frequency circuit
To use hollow core conductor to replace solid conductor.Additionally, in order to weaken Kelvin effect, also tend to use multiply phase in high-frequency circuit
Thin insulated wire braiding bunchy replaces the heavy gauge wire of same sectional area mutually, and this multiply wire harness is referred to as litzendraht wire.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problems referred to above, it is provided that the collection skin of a kind of built-in collection skin pipe
Heater.
This utility model solves its technical problem and be the technical scheme is that
The collection skin heater of a kind of built-in collection skin pipe, including the heat-insulation layer being arranged on conveying pipe, in described conveying pipe
Being provided with collection skin on wall and add heat pipe, described collection skin is added heat pipe and is fixed on the two ends of described conveying pipe, described collection skin by fixation clamp
Adding heat pipe to be welded on twist on described conveying inside pipe wall, described collection skin adds heat pipe and includes collecting skin cable and being arranged on described collection
The heat-generating pipe of skin cable outer layer, one end of described collection skin cable is connected to power circuit by cold cable, and its other end is by control
Circuit processed is connected to power circuit.
Preferably, described fixation clamp includes supporting described collection skin and adds two arranged in the bottom shelf of heat pipe and described bottom shelf
Individual quarter bend folding piece, described quarter bend folding piece is bolted on the outer surface of described conveying pipe.
Preferably, described power circuit includes that the change-over circuit being connected to 380V alternating current power supply is connected with described change-over circuit

The beneficial effects of the utility model are: this utility model has the advantage that
The most efficient
Intensive thermal contact that conduction of heat between heat-generating pipe and conveyance conduit is provided because of welding engineering and become more preferably.Heat
Amount can be managed to conveying from heat-generating pipe conduction effectively.Owing to heat-generating pipe can produce required 70%～90% heat, and remain
Waste heat amount is generation (being used for heating) in electric wire, and therefore, efficiency reaches 100%.
The most economical and the most practical
Collection skin cable within heat-generating pipe is used as feed cable.Therefore remote pipe installation cost becomes relatively low.Use
After this heating system, automatically provide heat the most when necessary.
The most reliable
Owing to pipeline is typically embedded type, therefore, any kind of pipeline (surface duct or underground piping) all can be pacified
Entirely use this utility model, it is not necessary to system is frequently maintained or pays close attention to.
Even if insulated electric conductor is impaired, still can easily and rapidly change impaired electric wire, nothing by rosette or junction box
Thermal insulation layer need to be dismantled or along whole affected heating part, pipeline is dug from the ground.
