Problems solved by technology

[0003] At present, most of the large collector tubes of solar water heaters on the market use glass vacuum tubes or circulation preheating technology. Glass vacuum tubes are fragile and inconvenient to load, unload, move and transport , Moreover, in some bad weather, such as hail disasters, it is very easy to damage the solar vacuum tube, thereby affecting the service life of the solar water heater and causing losses to people's property, and in winter in northern China, the cold weather is easy to freeze the glass vacuum tube. Therefore, The fragility and damage of glass vacuum tubes has become a problem restricting the development of solar water heaters. It is still a difficult problem for technicians in the industry to find a new heat collection method to replace glass vacuum tubes.

Embodiment 1

[0039] Such as figure 1 , figure 2 As shown, a solar thermal collector includes a thermal collector panel 1, a heat pipe 2 and a joint 3. The thermal collector panel 1 includes a metal substrate 6 and a glassy inorganic composite coating 5. The metal substrate 6 is stamped from a low-carbon steel plate. The vitreous inorganic composite coating 5 is enamelled on the lighting surface of the metal substrate 6, and the thickness of the vitreous inorganic composite coating 5 is 0.1 mm. The backlight surface of the metal base 6 is provided with a groove 4, and the heat pipe 2 is arranged in the groove 4. The groove 4 and the heat pipe 2 are both S-shaped coiled on the backlight surface of the metal base 6. The water inlet and outlet of the heat pipe 2 The nozzles are all provided with joints 3, and the heat pipe 2 is equipped with a superconducting medium.

[0040] A production process of the above-mentioned heat collecting panel, comprising the following process steps:

Embodiment 2

[0056] Repeat Example 1, with the following differences: the thickness of the vitreous inorganic composite coating 5 is 0.2mm, and the production process of the heat collecting panel comprises the following process steps:

[0057] a, the making of metal substrate 6

[0058] After cutting the low-carbon steel plate, it is punched and formed to obtain a metal matrix parison. The parison is subjected to oil burning→acid washing→water washing→coating with nickel→water washing→neutralization→drying→inspection and then ready for use to complete the production of the metal matrix 6;

[0059] In the oil burning process, put the metal matrix parison into a kiln at 650-750°C and heat it for 5-10 minutes;

[0060] In the pickling process, soak the oil-burned metal matrix parison in a sulfuric acid solution with a concentration of 8% for 3 to 8 minutes;

[0061] In the nickel-coating process, the metal matrix parison washed with clean water is put into a nickel sulfate solution with a co...

Embodiment 3

[0072] Repeat Example 1, with the following differences: the thickness of the vitreous inorganic composite coating 5 is 0.15mm, and the production process of the heat collecting panel comprises the following process steps:

[0073] a, the making of metal substrate 6

[0074] After cutting the low-carbon steel plate, it is punched and formed to obtain a metal matrix parison. The parison is subjected to oil burning→acid washing→water washing→coating with nickel→water washing→neutralization→drying→inspection and then ready for use to complete the production of the metal matrix 6;

[0075] In the oil burning process, put the metal matrix parison into a kiln at 650-750°C and heat it for 5-10 minutes;

[0076] In the pickling process, soak the oil-burned metal matrix parison in a sulfuric acid solution with a concentration of 7% for 3 to 8 minutes;

[0077] In the nickel-coating process, the metal matrix parison washed with clean water is put into a nickel sulfate solution with a c...

Abstract

The invention provides a production process of a solar heat collecting plate and a heat collecting panel utilized by the solar heat collecting plate. The production process comprises the following steps of: impacting a carbon-free steel plate to form the heat collecting panel with a groove; spraying a vitreous inorganic composite material on the light gathering surface of the heat collecting panel; sintering at high temperature; fusing the heat collecting panel with the inorganic composite material to form a novel black composite material; and fixing a heat conducting pipe filled with a superconducting medium on the groove in the back surface of the heat collecting plate by utilizing a high-temperature resistant adhesive, thereby forming the solar heat collecting plate with the enamel superconducting medium. The solar heat collecting plate provided by the invention is difficult in coating shedding, good in anti-vibration property, resistant to high temperature and low temperature, resistant to disaster weather such as hailstone, resistant to impact and difficult to break.
