Collector flowing channel

Abstract

The invention discloses a collector flowing channel which comprises a first flowing channel pipe and a second flowing channel pipe. One side of the first flowing channel pipe and one side of the second flowing channel pipe are connected. A plurality of first grooves are formed in one side of the first flowing channel pipe close to the second flowing channel pipe, a plurality of second grooves are formed in one side of the second flowing channel pipe close to the first flowing channel pipe, the number of the first grooves is identical with that of the second grooves, the first grooves and the corresponding second grooves form a closed cavity, and contact portions of the first flowing channel pipe and the second flowing channel pipe are connected in a welding mode. The collector flowing channel has the advantage of effectively solving the problem of water leakage at the welding position of a traditional collector flowing channel and a condensation sleeve. The collector flowing channel is simple in manufacture and low in cost.

Description

technical field [0001] The invention relates to a heat collector of a solar water heater, in particular to a heat collector flow channel. Background technique [0002] With the gradual improvement of people's living standards and the enhancement of awareness of using new energy sources, solar water heaters have been favored by many people and have gradually entered the homes of more ordinary people. Solar water heaters convert sunlight energy into heat energy, and heat water from low temperature to high temperature, so as to meet the hot water use in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. At present, vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collectors, water storage tanks, brackets and other related accessories. The conversion of s...

Problems solved by technology

However, in the heat collectors of the above patents, several perforations are first arranged on the stamped main channel, the condensation sleeve is placed in the perforation, and the joint between the condensation sleeve and the main channel is welded and fixed, and then the solar superconducting heat pipe Put it in the condensation sleeve for heating. This connection method will have a defect in practical application, that is, the welding part of the condensation sleeve and the main flow channel will increase or vibrate with the use of time due to the small area of ​​the connection. For other reasons, there will be cracks in the weld and water leakage. Once the collector leaks, the entire water heater will be unusable, and the manufacturing process of this collector is also relatively complicated. It is necessary to make a separate condensation sleeve and weld it.
