A solar collector is a device that absorbs solar radiation energy and transfers heat to its internal working fluid. It is a special heat exchanger. U-pipe solar collector is composed of copper tube, heat absorbing body, glass tube and metal end cover. After passing through the circulating pipe and holding the water tank, the solar radiation can be used to heat up the water. The vacuum tube of the u-pipe solar collector may need to be replaced, so the next step is how to replace the vacuum tube.
This is the content table of the article：

— Fixed pipe
— Fixed rubber cap
— Summary
1. For safety reasons, first wear protective gloves with rubber and wear protective gloves with rubber. The inner layer has a good rubber anti-slip effect, and the outer layer has a cotton fabric that is tough. Prevent the aging of the heat collecting tube from rupturing and hurting the hand, and it is safe to slip.
2. Then try to force the left and right rotation while disassembling the vacuum tube of the u-pipe solar collector. Hold the vacuum tube with both hands and try to rotate the vacuum tube to the left and right, then back to the right once. Repeat the above steps and try a few more times. Some of the need to be rusted by scale can be turned many times. Of course, if you haven't done this, your wrist may be a little bit painful.
After the vacuum tube can be rotated, gently push it upwards, about 20 cm into the heat preservation bucket, gently lift the bottom of the vacuum tube, slowly pull it out, and disassemble it.
3. The ingenious use of detergent. Before disassembly, apply a little detergent to the contact part of the top collector tube and the bucket, and wait for ten minutes to lubricate it, which has a certain effect. But pay attention to a little wipe, if there is a flow, hands slip, be sure to dry. In addition, when installing, the detergent is applied to the top of the vacuum tube, the effect is most obvious.
1. Wet the windshield with clean water, put it on the upper end of the vacuum tube of the U-tube solar collector and expose the port, and hold the tail of the tube with one hand to protect the tip of the tail. Hold the 1/3 of the tube with the other hand, and apply even force and keep the direction of force in line with the coaxial line of the nozzle. Insert the vacuum tube into the vacuum tube hole of the water tank. At this point, you can insert more than one section. After the tail of the vacuum tube is aligned with the guard, pull it out until the vacuum tube and the guard are firmly secured, and then close the windshield to the outer wall of the tank. The first vacuum tube is installed.
2. Install all the vacuum tubes in order according to the above steps, and install the vacuum tubes from one side to the other.
Firstly, the heat insulating plug for preventing the heat dissipation of the vacuum nozzle of the U-tube solar collector is fixed on the reserved hole of the joint box, and the high temperature resistant silicone sealing ring is placed on the fin housing. The vacuum tube sleeve is soaked in soapy water, and the U-shaped tube and the fin are inserted into the vacuum tube together, and the vacuum tube is closely connected with the heat-insulating plug and the sealing ring on the connection box. Then insert the end of the vacuum tube into the rubber end cap and fix it on the C-channel.
U-tube solar collector is a new type of new energy-saving product. It can be installed on the roof to insulate it. It can also beautify the roof function and realize the integration of solar energy and buildings. Of course, it is best to replace the vacuum tube in the u-pipe solar collector with a professional person to replace it. If there are special circumstances, it can be replaced according to the above method, but it is best to choose to replace it in the morning.
