The utility model with low processing cost can boil water for direct drinking.

Description

A solar water heater

technical field

The utility model relates to a heat exchange device, in particular to a solar water boiler.

Background technique

There are two main types of existing solar water boilers: one is to use a parabolic reflector to gather sunlight into a water container, and then heat the water, which has a complicated structure, high cost, and is inconvenient to install and use; Vacuum heat collecting tubes are used for heating, and multiple vacuum heat collecting tubes are placed horizontally or obliquely in parallel to heat and boil the water in the tubes, and there is a water storage tank for heat preservation, so the water volume is large and the water temperature rises slowly, which is not practical. It is not good for the health to drink the water heated by existing products directly, so it is mostly used as water for bathing.

Utility model content

The technical problem to be solved by the utility model is to provide a solar water boiler with low cost, high efficiency and direct drinking of boiled water.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a solar water boiler, which includes a bracket and vacuum heat collecting tubes arranged in parallel on the bracket. A metal casing for water, the lower part of the metal casing is provided with a water outlet pipe communicating with it.

Both ends of the above-mentioned vacuum heat collecting tube are opened, and one end is provided with a sealing plug; the vacuum heat collecting tube and the metal casing are relatively fixed by the provided sealing plug.

Preferably, the above-mentioned metal casing is any one of stainless steel metal casing, copper pipe and aluminum alloy casing.

Preferably, the metal sleeve is threaded or welded to the water outlet pipe.

As a further improvement, the water outlet pipe is connected with a water storage tank.

Preferably, the number of the above-mentioned vacuum heat collecting tubes is 2-20.

The beneficial effects produced by adopting the above-mentioned technical scheme are: the utility model adopts a double-layer casing structure, and a metal casing is arranged inside the vacuum heat collecting tube, the metal casing can be a stainless steel tube, and the boiled water can be directly drunk, because the The new type adds less water at one time, so the water can be boiled in a short period of time, which is not only low in cost, but also more convenient to install and use.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Referring to accompanying drawings 1 and 2, a metal sleeve 3 is added inside the vacuum heat collecting tube 2, and there is air between the metal sleeve 3 and the vacuum heat collecting tube 2, and heat is transferred through the air, thereby heating the water, and the amount of water is small, which can The water is boiled, because the stainless steel sleeve is in contact with the water, so the boiled water can be drunk. The material of the vacuum heat collecting tube 2 here can be the all-glass vacuum heat collecting tube used on the current solar heater or solar water boiler. The existing vacuum heat collecting tube is closed at one end, and the two ends of the vacuum heat collecting tube 2 are all made into openings. , the upper opening can be closed with a plug to prevent dirt such as dust from entering. The metal sleeve 3 adopts a circular metal tube with a cross-sectional shape, and can choose stainless steel tube, copper tube or aluminum alloy tube, preferably thin-walled stainless steel water pipe, which is widely used in building water supply and direct drinking water pipelines. It is harmless to the body, and the country already has relevant industry standards for "thin-walled stainless steel water pipes". A sealing plug 6 is arranged between the metal casing 3 and the vacuum heat collecting tube 2, and the friction force of the sealing plug is used to relatively fix the two. The section shape of the outlet pipe 4 is circular, and its upper part is provided with a plurality of three-way joints, which are similar to a three-way pipe structure. The end of the metal sleeve 3 is threaded, and then the outlet pipe 4 and the metal sleeve 3 are connected by thread Connect them to form a connected water flow channel; here you can also use welding to connect the two, process the circular outlet pipe 4 with round holes at regular intervals, and then align the metal sleeve 3 with the round holes , and then solder. The structure of the support can adopt the support used in the prior art at present, and the vacuum heat collecting tube is fixed stably to prevent it from moving when the wind blows, and simple processing and design can be carried out as required.

During use, the number of vacuum heat collecting tubes can be flexibly selected according to needs, and several vacuum heat collecting tubes are arranged in parallel and placed on the prepared bracket. In the utility model, when the sky is clear, if the temperature is 10°C, the water can be boiled twice a day after filling up the water, and the temporarily unused water can be stored in the water storage bucket, which can be used for heat preservation. Bucket, its position can be flexibly selected according to needs, and the water storage bucket can be connected with the water outlet pipe through the water pipe. Generally, 12 vacuum heat collecting tubes can add about 10kg of water, which can be selected according to the needs of water consumption. The utility model has the advantages of low manufacturing cost, convenient use and no pollution, and meets the development requirements of the current low-carbon environment-friendly economy.
