Description

An antifreeze water pipe matched with solar equipment

technical field

The utility model relates to solar energy equipment, in particular to an antifreeze water pipe matched with the solar energy equipment.

Background technique

Solar energy is an inexhaustible renewable energy source that has been widely used in real life, such as solar water heaters, solar heating, and solar air conditioning. These devices all have outdoor water pipes, and in cold weather, there is a problem that the water pipes are easy to be frozen or even cracked.

In the prior art, there is a superconducting heat pipe, which is composed of a tube shell, a new liquid-absorbing core and an end cover. After the inside of the tube is pumped into negative pressure, it is filled with an appropriate amount of working liquid, so that the liquid-absorbing core close to the inner wall of the tube is capillary and porous. The material is filled with liquid and sealed. One end of the tube is the evaporation section and the other end is the condensation section. An insulating section can be placed between the two sections as required by the application. When one end of the heat pipe is heated, the liquid in the capillary wick evaporates and vaporizes, and the steam flows to the other end under a small pressure difference to condense into a liquid, and the liquid flows back to the evaporation section along the porous material by capillary force. In this endless cycle, heat is transferred from one end of the heat pipe to the other end. The super thermal conductivity of the heat pipe makes its thermal conductivity about 10,000 times that of ordinary metals. The heat pipe conduction temperature does not decay and can be transmitted at an extremely fast speed (transfer at the speed of sound).

Utility model content

The purpose of the utility model is to provide an antifreeze water pipe matched with solar energy equipment, which has good antifreeze effect and convenient and fast installation and improvement.

The purpose of the utility model is achieved in the following way: an antifreeze water pipe matched with solar energy equipment, including a water pipe, a superconducting heat pipe is arranged in the water pipe, and one end of the superconducting heat pipe is connected with a heat source.

The beneficial effect of the utility model is that: the working principle of the superconducting heat pipe is as follows: when it is hot, it absorbs it, and when it is cold, it releases it, so that one end of the superconducting heat pipe absorbs heat from the heat source and releases heat in the water pipe, so that the temperature of the water in the water pipe is the same as that of the water in the water pipe. The temperature of the heat source is the same, as long as the heat source has heat, the water pipe will not be frozen. At the same time, the water pipes should be well insulated to minimize heat loss. If the length of a single heat pipe is not enough, multiple heat pipes can be connected in series to carry out relay transfer of heat. The utility model has a simple structure and is easy to install, and can directly improve the water pipes of existing solar energy equipments in use. The utility model can be used in solar water heaters.

As an improvement of the utility model, the heat source is a hot water storage tank of a solar energy device. Since one end of the heat pipe extends into the water tank, the heat pipe transfers the temperature inside the water tank to the water pipe, so that the temperature in the water pipe can be kept consistent with the temperature in the water tank, preventing the water in the water pipe from being frozen when the temperature is low Simultaneously, the heat-conducting pipe stretching into the water tank can also play the role of uniform water temperature inside the water tank, avoiding the situation that the water temperature of the upper layer in the water tank is higher than that of the lower layer, and the user first uses the water with low temperature instead of the high water.

As an improvement of the utility model, the superconducting heat pipe is a sintered pipe.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the present invention.

Among them, 1 hot water storage tank, 2 superconducting heat pipes, 3 water pipes, and 4 hot water outlets.

Detailed ways

A kind of antifreeze water pipe matching with solar energy equipment as shown in Figure 1, comprises water pipe 3, is provided with superconducting heat pipe 2 in the water pipe, and one end of described superconducting heat pipe is connected with the hot water storage tank 1 of solar water heater, and water pipe 3 It is connected with the hot water port 4, and the superconducting heat pipe 2 is a sintered pipe.

In the utility model, one end of the superconducting heat pipe 2 extends into the hot water storage tank 1, and the other end extends to the joint of the indoor and outdoor water pipes or the hot water outlet, and the joint of the indoor and outdoor water pipes can ensure that the outdoor water pipes will not be (Indoor water pipes are generally not frozen), but when using hot water, part of the cold water must be released first, and extended to the hot water outlet to ensure that hot water will come out as soon as the faucet is turned on. If the length of a single superconducting heat pipe 2 is not enough, multiple superconducting heat pipes 2 can be connected in series without affecting the use effect. At the same time, the outdoor water pipe 3 will be well insulated to minimize the loss of heat.

When working, hot water is discharged from the water tank 1 through the water pipe 3 from the hot water port 4, and since one end of the superconducting heat pipe 2 is inserted into the inside of the water tank 1, the superconducting heat pipe 2 transfers the temperature inside the water tank 1 to the water pipe 3, Therefore, the temperature in the water pipe 3 can be kept consistent with the temperature in the water tank 1 to avoid freezing in the water pipe 3 when the temperature is low; at the same time, the superconducting heat pipe 2 can also play the role of uniform water temperature in the water tank 1; the internal capillary The structure is a sintered tube manufactured by sintering copper powder at high temperature, so that the heat transfer has no directionality. When installing the sintered tube, there is no need to consider the angle direction of the tube, which makes the installation more convenient.

The utility model is not limited to the above-mentioned embodiments. On the basis of the technical solutions disclosed in the utility model, those skilled in the art can make some technical features based on the disclosed technical content without creative work.
