Abstract
The present invention relates to a skin effect heating device for built-in skin effect pipe, comprising a heat-insulation layer mounted on a delivery pipe. The inner wall of the delivery pipe is provided with a skin effect heating pipe. The skin effect heating pipe is fixed at two ends of the delivery pipe through fixing clamps. The skin effect heating pipe is welded onto the inner wall of the delivery pipe in a spiral shape. The skin effect heating pipe comprises a skin effect cable and a heating pipe arranged on the external layer of the skin effect cable. One end of the skin effect cable is connected to a power supply circuit through a cold cable while the other end is connected to the power supply circuit through a control circuit. According to the invention, a better heat conduction performance can be achieved between the heating pipe and the delivery pipe for the intensely arranged heat contact points provided by welding engineering. The heat can be effectively transmitted from a heating pipe to a delivery pipe at a rate of 100%. With a lost cost to manufacture, the heating device is economical. As most pipes are embedded ones, the device can be safely applied to all pipes without having to administrate frequent maintenance and attention to a system.
Description
Technical field
The present invention relates to the collection skin heater of a kind of built-in collection skin pipe, belong 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.
Summary of the invention
The technical problem to be solved in the present invention is: for overcoming the problems referred to above, it is provided that the collection skin heating of a kind of built-in collection skin pipe
Device.
The technical solution adopted for the present invention to solve the technical problems is:
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

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
IGBT inverter circuit.
Preferably, described control circuit includes that PLC, described change-over circuit and IGBT inverter circuit are all with described
PLC connects.
The invention has the beneficial effects as follows: the invention have the advantages 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 the present invention, 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
