Abstract

The utility model relates to an auto -parts provides a self -limiting temperature fails oil pipe and includes oil pipe, is equipped with the zone of heating between oil pipe's inlayer and the skin, the zone of heating is a ribbon heater of being made by automatic control temperature material, ribbon heater along oil pipe's axial and inlayer contact setting, the outside along the selective heat preservation that is equipped with of circumference of zone of heating. The utility model discloses the zone of heating is kept apart with the fuel, effectively avoids the unsafe factor who produces the fuel direct heating, effectively prolong oil pipe's life, consume low battery, the invariant of generating heat, can be according to the oil pipe intercepting of different needs to producing, reduce cost, convenient and practical, the installation of being convenient for.

Description

A kind of from the warm transport pipe of limit

Technical field

The utility model relates to a kind of auto parts machinery, is specifically related to a kind of from the warm transport pipe of limit.

Background technique

When winter, temperature was lower, uses automobile or other diesel engine of diesel oil, cannot start because diesel oil freezes, used electric heating in the past, the diesel oil of whole oil circuit is thawed, thaws and need the long time, prestarting diesel oil preheating overlong time.Although there are some electric heating transport pipe on the market, its structure is mostly inside and wears heating wire, hinders the flowing of fuel oil like this, dangerous large; Some are in the structure of tube inner wall composite heating silk.These structures, all because of the requirement of power, must shift to an earlier date customized and directly can not intercept use the later stage, are difficult to the installation requirements adapting to different length.

Summary of the invention

The utility model provides a kind of and realizes safe heating from the warm transport pipe of limit, and need to intercept according to different length, achieve scale and determine power, power consumption is low, has function that is temperature automatically controlled, limit temperature.

The utility model is by the following technical solutions: a kind of from the warm transport pipe of limit, comprise oil pipe, be provided with zone of heating between the internal layer of oil pipe and skin, described zone of heating is a ribbon heater of being made up of automatic temperature-control material, and ribbon heater is arranged along the axis of oil pipe and inner layer contacts.

For the ease of insulation, the outside of described zone of heating is circumferentially provided with thermal insulation layer.

Preferably, described ribbon heater is that the temperature of limit certainly that PTC material is made accompanies (adding) torrid zone, temp auto-controlled accompanies (adding) torrid zone, Self-controlled companion (adding) is tropical, temp auto-controlled adds (companion) heat-resistant cable, from the one limitting temperature to add (companion) heat-resistant cable.

Preferably, one or more in described PTC material Graphene, carbon element semiconductor, conductive nano particle, conductive plastic and carbon black.

Preferably, described outer field material is any one in nylon, rubber, plastics, rubber-plastics material.

Usefulness of the present utility model is: zone of heating and fuel oil are isolated, and effectively avoids directly adding thermogenetic unsafe factor to fuel oil; Heat generating material is one or more in Graphene, carbon element semiconductor, conductive nano particle, conductive plastic and carbon black, realizes temperature automatically controlled, and without the phenomenon such as overheated, effectively extend the working life of oil pipe, power consumption is low, generates heat constant; Can need to intercept the oil pipe produced according to difference, reduce costs, convenient and practical, be convenient to install.

Embodiment

Embodiment one

As depicted in figs. 1 and 2, the utility model comprises oil pipe 1, and material is the standard oil pipe of any one in rubber, nylon, metallic material, can be equipped with any type of modular connection.

The zone of heating 5 that the ribbon heater being provided with an automatic temperature-control material between the internal and external layer of oil pipe 1 is made, ribbon heater is that the temperature of limit certainly that PTC material is made accompanies (adding) torrid zone, temp auto-controlled accompanies (adding) torrid zone, Self-controlled companion (adding) is tropical, temp auto-controlled adds (companion) heat-resistant cable, from the one limitting temperature to add (companion) heat-resistant cable, this automatic temperature-control material is one or more in Graphene, carbon element semiconductor, conductive nano particle, conductive plastic and carbon black.

Zone of heating 5 to contact with internal layer 6 along the length direction of oil pipe 1 and arranges, and is provided with the terminal be connected with one end, ribbon heater 5 outside oil pipe 1, and skin 4 material of oil pipe 1 is any one in nylon, rubber, plastics, rubber-plastics material.

Embodiment two

The difference part of the present embodiment and embodiment one is, in order to further insulation, the outside of zone of heating 5 is provided with thermal insulation layer circumferentially, reduces overall heat loss further.
