AI Technical Summary

Problems solved by technology

Both have the following disadvantages: 1. The metal tube-sheet heat collector mainly adopts materials such as copper and aluminum, and the structure and manufacturing process of the vacuum glass tube heat collector are relatively complicated. high

2. Both of them use black sunlight absorbing paint coated at low temperature. Under the long-term sunlight, there will be a certain degree of aging to attenuate the sunlight absorption rate, the metal is easy to corrode, and the vacuum degree in the vacuum glass tube will gradually decrease. Significant Cause of Lifetime and Efficiency Issues

3. It is difficult to integrate with buildings due to reasons such as materials, structure, cost and lifespan

[0003] Coating industry, food industry, textile industry, printing and dyeing industry, grain drying, etc. require a lot of energy-consuming drying process. The drying process is mainly to get rid of moisture and organic volatiles in the product, so that its molecules can accelerate vibration and movement speed and increase kinetic energy. Thermal drying is to gradually heat the product from the outside to the inside. The disadvantage is that the efficiency is low, and it is easy to make the surface of the product form a film first, and the internal volatiles will penetrate the surface film layer to be removed, and the surface is prone to produce pores. and bubbling, causing quality problems

Far-infrared rays have a certain penetrating power to organic matter, which can heat up the inside and outside at the same time, which is conducive to the discharge of internal moisture and organic volatiles, and improves efficiency and product quality. Far-infrared rays usually refer to rays with a wavelength of 2.5-25μ. At present, far-infrared heating Devices mostly use components such as silicon carbide coated with far-infrared coatings, infrared lamps, and quartz glass tubes. The prices are relatively high. The general emissivity of infrared coatings is 0.83 to 0.95. Peeling pollutes the object to be dried, the temperature of the heating element of the infrared lamp is too high, the wavelength is biased toward the near infrared, and the energy distribution of the quartz glass tube is relatively concentrated, which affects the universality of various drying objects

[0004] Indoor heating uses a large number of metal radiators, or radiators, which are generally installed on the wall or under the window sill. When the radiator is heated by the medium, it dissipates heat. Except for a small amount of heat dissipated in the form of radiation and air conduction, most of the heat comes from the rising thermal airflow. Drive the indoor air convection circulation to transfer heat to all parts of the room. In the second half of the 20th century, people found that the indoor rising hot air flow hinders the settlement of dust, and it is easy to spread the dust and bacteria carried by the ground and near the ground to all parts of the room with the airflow. It is easy to be inhaled by the human body and is not conducive to health. Therefore, it is proposed that the heat of the heat sink should be more infrared radiation to reduce conduction and convection, and far-infrared radiation can promote blood circulation in the human body, which is more conducive to health. , so as to put forward the requirement of using far-infrared heat sink as far as possible, but due to the high price of infrared coating and easy to fall off, far-infrared heat sink has not been fully promoted

In the past, cast iron heat sinks were mostly used for heat sinks. Due to poor production conditions, unsightly appearance, and large land occupation, the production volume has decreased year by year. Instead, hollow steel heat sinks have various paints and patterns on the outer surface, and the thickness of the single board is relatively thin. , takes up less space, but hot water is very corrosive to steel, especially welds, so people use various anti-corrosion coatings with strong adhesion and bonding force to inject into the inner cavity of the heat sink to cover the inner surface, In order to improve the life of the steel heat sink, due to the complex structure, it is difficult to achieve tightness and long-term coverage, so the service life of the steel heat sink has always been a problem, and the cost of the copper heat sink is too high
