Air energy water heater and fixing component of heat exchange tube on outer wall of water tank thereof

Abstract

The invention provides a fixing component of a heat exchange tube on an outer wall of a water tank, which is used for fixing the heat exchange tube on the outer wall of the water tank. The fixing component comprises a pressing pad built on the heat exchange tube, and a tube clamp built on the pressing pad, wherein multiple clamping grooves corresponding to the pipeline positions of the heat exchange tube are formed in the pressing pad at intervals; and connecting parts fixedly connected with the water tank are arranged on the tube clamp and the pressing pad. As the multiple clamping grooves corresponding to the pipeline positions of the heat exchange tube are formed in the pressing pad, when the heat exchange tube is fixed through the pressing pad and the tube clamp, multiple pipelines of the heat exchange tube can be synchronously fixed on the outer wall of the water tank through one set of pressing pad and tube clamp, so that the fixing structure of fixing the heat exchange tube on the outer wall of the water tank is simplified. The invention further provides an air energy water heater.

Description

technical field [0001] The invention relates to the technical field of water heaters, more specifically, to an air energy water heater and a heat exchange tube fixing assembly on the outer wall of a water tank thereof. Background technique [0002] The outer wall of the water tank of the air energy water heater is wound with heat exchange tubes, and the heat exchange tubes are wound on the outer wall of the inner tank in a spiral manner through a certain tension to exchange heat. During the winding process of the heat exchange tube, it is necessary to fix the start section and the end section of the heat exchange tube with tube clamps to prevent the heat exchange tube from loosening and affecting the heat exchange effect. [0003] Generally, the heat exchange tubes are wound on the outer wall of the inner tank of the water tank in two or more parallel ways. Put the rubber pads on the top surface of the heat exchange tubes on the inner tank of the water tank. Most of the rub...

Problems solved by technology

During the winding process of the heat exchange tube, the start section and the end section of the heat exchange tube need to be fixed by the tube clamp to prevent the heat exchange tube from loosening and affecting the heat exchange effect

[0003] Generally, the heat exchange tubes are wound on the outer wall of the inner tank of the water tank in two or more parallel ways. Put the rubber pads on the top surface of the heat exchange tubes on the inner tank of the water tank. Most of the rubber pads used are separated. Clamps, and finally fixed with nuts, this method is complicated to install and operate, the rubber pad is easy to fall, and the production efficiency is low

And the rubber pad can only separate the heat exchange tube and the contact surface of the tube clamp, but cannot protect the heat exchange tube adjacent to the end face of the tube clamp, so the sharp edge of the tube clamp is easy to touch the heat exchange tube and cut the heat exchange tube , causing refrigerant leakage, which in turn causes the water tank to be scrapped

[0004] For the fixing method of two-way parallel pipe winding, a single water tank needs 8 pipe clamps, 16 screws, 16 nuts and 8 rubber pads for fixing, while for the three-way parallel pipe winding method, 12 pipe clamps are required , 24 screws, 24 nuts and 12 rubber pads for fixing. Using this production and assembly method, the number of parts is large, the installation is complicated, and the production efficiency is very low. The number of screws welded on the inner tank of the water tank is large, leaving many welding points , because the solder joints are easy to corrode, thus increasing the hidden danger of water tank leakage
