Description

Technical Field

[0001] The invention discloses a high-energy-efficiency composite heat exchanger for a high-temperature air purifier, belonging to the field of heat exchange equipment. Background Art

[0002] At present, high-temperature air disinfection is a commonly used sterilization method in medical and laboratory fields. Traditional high-temperature disinfection equipment usually relies on electric heating or gas heating, which has high energy consumption and low thermal efficiency. For example, common high-temperature sterilization cabinets usually need to maintain high temperatures (such as above 160°C) for a long time, resulting in significant energy waste. In addition, the heat recovery rate of existing equipment is low, and a large amount of heat is lost with the exhaust, further increasing operating costs. Although some improved equipment adopts thermal insulation design or waste heat recovery technology, the structure is complex and the cost is high, making it difficult to popularize. At the same time, traditional high-temperature disinfection devices are prone to excessive energy consumption or substandard disinfection effects. Especially under frequent start-stop conditions, the energy consumption problem of the equipment is more prominent. Therefore, there is an urgent need for a high-energy-efficiency composite heat exchanger for high-temperature air purifiers. By optimizing the heat circulation system and improving the thermal insulation performance, it can significantly reduce energy consumption while ensuring the disinfection effect. The device should have the characteristics of high thermal energy utilization efficiency and a wide range of applications to meet the needs of energy conservation, environmental protection and economy. This patent application aims to solve the above technical defects and provide a heat utilization solution for high-temperature air purifiers with a simple structure, energy saving and high efficiency. Summary of the Invention

[0003] The object of the present invention is to provide a high-energy-efficiency composite heat exchanger for a high-temperature air purifier, which has the characteristics of wide application range, high heat utilization efficiency and low cost.

[0004] A high-efficiency composite heat exchanger for a high-temperature air purifier comprises a spiral guide plate, a heat pipe bundle, a cylindrical wall, and a baffle. The spiral guide plate is attached to the outer end of the heat pipe bundle. The heat pipe bundle is surrounded by 40 heat pipes, with the lower end being a boiling end and the upper end being a condensing end, which are closely connected to the inner end of the spiral guide plate, forming a cold end at the top and a hot end at the bottom. The outer end of the cylindrical wall is closely connected to the heat pipe bundle. The baffle is a semicircular thin plate attached to the inner layer of the cylindrical wall and arranged in an alternating pattern up and down.

[0005] As a further improvement, the spiral drainage piece is a drainage device made of a special aluminum alloy; the overall height is 600-660mm, the spiral outer diameter is 200-220mm, the spiral inner diameter is 150-160mm, and the number of turns is 5-6.

[0006] As a further improvement, the heat pipe bundle is located inside the spiral drainage plate and is surrounded by 40-50 heat pipes made of special copper alloy; the heat pipe bundle radius is 150-160mm, the heat pipe radius is 20-30mm, and the height is 670-690mm.

[0007] Compared with the existing technology, the benefits of the present invention are: a high-energy-efficiency composite heat exchanger for a high-temperature air purifier, the spiral guide plate on the outside of the heat exchanger can extend the air flow time and heat exchange time, maximize the heat energy recovery and utilization efficiency, and greatly reduce the loss of heat energy; the heat pipe bundle formed by the heat pipes effectively improves the heat energy utilization efficiency while increasing the heat exchange area, and greatly reduces the loss of heat energy.

[0022] The technical solution of the present invention is further described in detail below through specific embodiments:

[0023] Embodiment: After being heated to above 200°C, the air enters the heat transfer zone (8); the flow time in the heat transfer zone (7) lasts for 6 seconds to 8 seconds, and the heat of the hot air is transferred to the heat pipe bundle (2) through heat conduction, and then the heat pipe boils and absorbs heat to quickly transfer the heat to the air just introduced above, performing waste heat treatment on the air just introduced, so that the temperature of the newly introduced air is raised to about 100°C before reaching the heating zone (8); and the temperature of the hot air can be reduced to below 30°C after passing through the heat exchange zone (7), so as to achieve efficient recycling of heat; when the hot air leaves the heat exchange zone (7) and reaches the air outlet, the temperature is reduced to about 24°C, which is the room temperature, and then discharged from the outlet.
