Problems solved by technology

The diameter of the outer tube of the existing vacuum heat collecting tube is generally 47mm, 58mm or 70mm; the vacuum heat collecting tube with an outer diameter of 70mm and a length of 2m is the largest conventional vacuum heat collecting tube. The main function of the existing vacuum heat collecting tube is Absorb solar energy, and then the heat in it is stored in the water tank through thermal convection, and the water tank is responsible for storing hot water. Due to the size of the existing vacuum heat collecting tubes, only a small amount of hot water can be stored in the vacuum heat collecting tubes; When the heat collecting tube is inserted into the water tank, it is necessary to open multiple holes on the water tank to cooperate with the vacuum heat collecting tube, which reduces the thermal insulation performance of the water tank, and the heat collecting system composed of multiple vacuum heat collecting tubes and the water tank requires a relatively large bracket and costs a lot. High, time-consuming and labor-intensive installation

Embodiment Construction

[0013] exist figure 1 In the single-tube vertical heat collector, one end of the outer glass tube 1 and the inner glass tube 2 of the vacuum heat collecting tube are welded to each other to form the open end of the vacuum heat collecting tube, and the other ends of the outer glass tube 1 and the inner glass tube 2 are respectively sealed to form The free end is coated with a heat-absorbing film on the outer surface of the inner glass tube 2. The outer diameters of the inner glass tube 2 and the outer glass tube 1 at the open end are respectively 58 mm and 70 mm. The average of the inner glass tubes The outer diameter is 200mm, and the length of the outer glass tube is 2000mm. The open end of the vacuum heat collecting tube is inserted into the side of the bottom of the water tank 3, and a silica gel sealing ring 4 is arranged between the water tank 3 and the vacuum heat collecting tube. There are water inlet pipe 5, water outlet pipe 6 and exhaust pipe 7.

Abstract

The invention discloses a single-pipe vertical heat collector. A heat collecting system is characterized in that only one large-size vacuum heat collecting pipe with a reducing opening end is adopted and inserted into the side surface of the lower part of a water tank; and one end of the water tank is arranged on the ground, a wall surface and other supporting objects. The single-pipe vertical heat collector has the advantages that cost of a support is omitted; the structure is simple; and the assembly is convenient.

Description

technical field [0001] The invention relates to a solar water heater using only one vacuum heat collecting tube, and the solar water heater no longer needs traditional support. Background technique [0002] Existing solar water heaters are mainly composed of several vacuum heat collecting tubes inserted into a water tank; the water tank is composed of a stainless steel shell and an inner tank wrapped with a polyurethane insulation layer; the vacuum heat collecting tube is an all-glass double-layer glass vacuum tube, and its general structure includes outer glass Tube, inner glass tube, a low-pressure vacuum layer between the outer glass tube and the inner glass tube, the outer surface of the inner glass tube is coated with a heat absorbing layer, one end of the outer glass tube and the inner glass tube are self-sealing to form a free end, the outer glass tube The other end of the tube is welded to the other end of the inner glass tube to form an open end. The diameter of th...
