Anti-water leakage heat exchange tube device and method for connecting and mounting same

Abstract

The invention relates to the filed of solar water heating devices, in particular to an anti-water leakage heat exchange tube device in a solar vacuum heat collecting tube and a method for connecting and mounting the same with a water tank of a solar water heating device. The anti-water leakage heat exchange tube device is provided with a trumpet type tube mouth, wherein the bottom of the trumpet type tube mouth is connected with a straight-neck tube section; and the bottom of the straight-neck tube section is connected with a heat exchange tube body which is sealed and plugged at bottom. The method comprises the following steps that: the trumpet type tube mouth and the straight-neck tube section are inserted into the water tank through a connection port of the water tank, wherein the size of the connection port of the water tank is a little bit greater than that of the outside diameter of the trumpet type tube mouth; a sealing ring is sleeved on the heat exchange tube body and is pushed to be arranged at the position of the connection port of the water tank; the anti-water leakage heat exchange tube is pulled outward, so that when the straight-neck tube section passes through the sealing ring arranged at the positioned of the connection port of the water tank and is pulled to the position of the lower end of the trumpet type tube mouth, the trumpet type tube mouth is arranged and clamped at the position of the connection port of the water tank under the action of the sealing ring due to the fact that the thickness of the sealing ring reduces the size of the diameter of the connection port of the water tank; and the straight-neck tube section below the trumpet type tube mouth isolates the water tank of the solar water heating device and the inner cavity of the anti-water leakage heat exchange tube from the outside through the sealing ring.

Description

technical field [0001] The invention belongs to the field of design and manufacture of a heat exchange tube used in a vacuum heat collection tube on a solar water heating device and the technical field of connection with a water tank of the solar water heating device, and specifically relates to a water leakage-proof heat exchange tube device and a connection and installation method. Background technique [0002] At present, most of the solar water heating devices used in people's lives adopt direct heating vacuum heat collecting tubes, and the heat absorbing film on the vacuum heat collecting tubes absorbs sunlight energy to heat up the water in the tubes. But the shortcoming of the existing vacuum heat collecting tube is that it holds a lot of water, the temperature rises slowly, and the heat exchange efficiency is low. As a result, the solar water heating device heats the water in the water tank at a slow rate. In addition, the vacuum heat collecting tube is made of glas...
