Solar heat collection device and manufacturing method of solar heat collection device

Abstract

The invention discloses a solar heat collection device. The solar heat collection device comprises a heat collection box and a super-heat-conduction pipe. The heat collection box comprises a box bodyand a sealing plate, wherein the box body is used for containing a target medium and is provided with an opening, and the sealing plate is arranged at the opening in a covering mode. The super-heat-conduction pipe comprises a sealed pipe body and super-conduction liquid injected into the pipe body. The pipe body comprises a heat collection part and a heat-exchange part communicating with the heatcollection part, wherein the heat collection part is located outside the box body, and the heat-exchange part is located in the box body. The pipe body is inlaid in the sealing plate through intra-mold injection. The invention further discloses a manufacturing method of the solar heat collection device. The manufacturing method of the solar heat collection device comprises the steps that the pipebody of the super-heat-conduction pipe is manufactured; the pipe body is placed in an injection mold, and injection molding is conducted outside the pipe body through an intra-mold injection process to form the sealing plate; the super-conduction liquid is injected into the pipe body; and the sealing plate is arranged at the opening of the box body in the covering mode, the heat collection part ofthe pipe body is located outside the box body, and a heat-exchange part of the pipe body is located in the box body.

Description

technical field [0001] The invention relates to the technical field of solar heat collection, in particular to a solar heat collection device and a manufacturing method of the solar heat collection device. Background technique [0002] With the rapid development of my country's economy, new index requirements have been put forward for the cleanliness and cost limits of energy consumption in various industries. Especially in the heating season in northern my country, smog is generated due to insufficient coal combustion and other reasons, which seriously affects air quality. . In order to reduce the consumption of coal for heating, change the habit of energy consumption, and improve the livability level, the country is gradually promoting the work of "clean energy". The medium and low temperature solar energy below 150° is playing an increasingly important role in the social energy supply system as clean energy. . [0003] The solar heat collecting device absorbs heat throug...

Problems solved by technology

During assembly, the head of the heat collecting tube needs to pass through the connecting piece on the heating box and enter the inside of the heat collecting box. To ensure the sealing between the heat collecting tube and the connecting piece, the heat collecting tube in the prior art extends into the heat collecting box The head of the head is a straight tube structure, and the length extending into the heat collection box is short, resulting in a small heat exchange area between the heat collection tube and the target medium in the heat collection box, and low heat exchange efficiency
