CN201637160U - Solar energy new outdoor antifreeze connection water pipe - Google Patents

Abstract

The utility model discloses a novel outdoor solar anti-freezing connecting water pipe which belongs to pipes with heat generation devices, in particular to a solar defrosting and anti-freezing pipe, an outdoor water pipe which connects a thermal insulation tank of a solar water heater with an indoor water supply and drainage pipe is easy to be frozen and iced for blocking water flow in cold winter in the north of China, thereby affecting the normal use. The novel outdoor solar anti-freezing connecting water pipe is as follows: electric heating wires are locally plastic packaged and embedded in the pipe wall of the outdoor connecting water pipe along the axial direction, when a power supply is switched on, the electric heating wires can heat the frozen water pipe locally in the longitudinal direction, firstly melt local ice which is near to the electric heating wires in the water pipe, form a small channel along the water pipe, and then completely melt the rest of ice by relying on hot water in the thermal insulation tank of the solar water heater, thereby deicing and saving energy by locally using the electric heating wires for heating the water pipe.

Description

Solar energy new outdoor antifreeze connection water pipe

technical field

The utility model belongs to pipes with heat generating devices in general, in particular to solar thawing antifreeze pipes.

Background technique

Solar water heaters are now widely used. Even in the cold winter, the sunlight in sunny days can heat the water in the solar water heater incubator to meet the requirements of showering. However, the temperature often drops suddenly, and the water pipes connected to outdoor solar water heaters freeze to block the water flow. , affecting normal use. Existing Chinese Patent No. is a kind of solar energy thawing antifreeze pipe patent of 01236159.3, and it is made up of water pipe, the heating wire that is wound outside the water pipe and the protective layer outside the heating wire. The technical solution is to install a heating wire outside the water pipe. When the weather is cold and the water in the water pipe is likely to freeze, or after the water pipe is frozen, the heating wire is used to heat it to achieve the purpose of thawing and antifreezing. In fact, it is necessary to heat the entire water pipe as a whole. Of course, the heating wire consumes a lot of energy and is not economical.

Utility model content

In order to overcome the deficiency that the existing outdoor connecting water pipes of solar water heaters are easy to freeze and the existing deicing technology consumes a lot of energy, the utility model provides a new type of solar energy outdoor antifreeze connecting water pipes. Its own hot water compensates for deicing, which is scientific and simple.

The technical solution adopted by the utility model to solve the technical problem is: a new type of solar energy outdoor antifreeze connection water pipe, including the water pipe wall and the heating wire, which is characterized in that: in the interlayer of the inner pipe wall and the outer pipe wall of the water pipe, along the axial direction The direction is partially plastic-encapsulated and inlaid with electric heating wires.

There are at least two heating wires arranged in the axial direction.

The beneficial effect of the utility model is that in the interlayer of the inner pipe wall and the outer pipe wall of the water pipe, electric heating wires are partially plastic-encapsulated and inlaid along the axial direction, so that local heating is used for the water pipes, and when the power is turned on, the electric heating wires are used for freezing. The water pipe is heated locally in the longitudinal direction. First, the local ice in the water pipe close to the electric heating wire is melted, and a small channel is formed along the water pipe, and then the rest of the ice can be completely melted by the hot water in the solar water heater incubator. In this way, the local heating with the electric heating wire, And use its own hot water to compensate for deicing, which is scientific and simple, and reduces energy consumption.

Accompanying drawing 1 is the structural representation of the utility model,

In the figure, 1. inner pipe wall, 2. outer pipe wall, 3. heating wire.

Detailed ways

The specific embodiment of the present utility model is, as shown in the figure:

Embodiment 1, a new type of solar energy outdoor antifreeze connection water pipe, including the water pipe wall and the electric heating wire 3, is characterized in that: in the interlayer between the inner pipe wall 1 and the outer pipe wall 2 of the water pipe, electric heating is partially plastic-encapsulated along the axial direction Wire 3, for example, there are two heating wires 3 arranged in the axial direction, so when the power is turned on, the heating wire 3 will heat the frozen water pipe longitudinally and locally, first melt the local ice in the water pipe close to the heating wire, and form a small channel along the water pipe , and then rely on the hot water in the solar water heater incubator to completely melt the rest of the ice.
