Abstract

The invention discloses a flat plate collector with worm pipes. The flat plate collector comprises a frame; high-light-transmission tempered glass is embedded on the frame; an absorber plate core is arranged below the tempered glass and comprises a heat exchange pipe, heat exchange volutes and heat collecting pipes as many as the heat exchange volutes; each heat collecting pipe comprises a heat collecting runner and heat collecting fins which are integrally formed on the two sides of the heat collecting runner; the heat exchange pipes pass through a plurality of heat exchange volutes; the upper part of each heat collecting runner is communicated with one corresponding heat exchange volute, and the lower part of each heat collecting runner is sealed independently; and the heat exchange pipe, the heat exchange volutes and the heat collecting runners form a closed space which is filled with a heat pipe medium. The flat plate collector has the advantages that as the heat collecting pieces are formed through one-time extrusion, the problems on firmness and heat resistance caused by laser welding or ultrasonic welding are avoided; the defects of frost cracking of a common heat collector in winter and scaling of a pipeline of a common flat plate collector are overcome; and a channel can be formed in each heat collecting runner, and thus the heat transfer effect of the flat plate collector can be improved effectively.

Description

technical field

[0001] The invention relates to a solar heat collector, in particular to a flat plate heat collector. Background technique

[0002] The flat-plate solar collectors commonly used in the market currently include copper runners and heat-absorbing plates with heat-absorbing coatings. The upper heat collector runner, the lower heat collector runner and the middle heat collector branch pipe form an "H" type copper runner, and the aluminum plate or copper plate with heat absorbing coating is welded on the heat collector branch pipe by ultrasonic or laser welding. Water is stored in the copper flow channel. When the sun shines on the plate with heat-absorbing coating to heat it, the plate then transmits heat to the heat collecting branch pipe to heat the water inside the branch pipe. Hot water will store heat in the water tank through circulation, forming a commonly used household solar water heater system. Its disadvantages are: the upper collector runner, the low...
