Description

Technical Field

[0001] The utility model relates to the field of air-conditioning equipment, in particular to a roller-type slide device for side extraction of coils. Background Art

[0002] Finned heat exchange coils are a common component in central air conditioning terminal units, providing cooling and dehumidification. Due to the high humidity experienced year-round, the coils are prone to dust and dirt accumulation, which can affect the heat exchanger's efficiency and even lead to corrosion of the coil fins. Air conditioning units used in food processing facilities and hospital operating rooms must also prevent bacterial growth on the heat exchange coils, necessitating regular cleaning and maintenance, or even replacement.

[0003] Coil cleaning and replacement typically requires removing the cabinet panels and using a lifting device to move the coil, which complicates assembly and disassembly. Without a lifting space, the coil cannot be moved manually, requiring cleaning and maintenance in a reserved area inside the cabinet. Coil maintenance is typically performed until the coil's performance fails to meet process or hygiene requirements, requiring a major overhaul or replacement.

[0004] Finned heat exchange coils are typically located in the center of an air handling unit (AHU), with the air inlet filtration section upstream and the heating, humidification, and blower sections downstream. Equipment in this central area is difficult to maintain, and the heat exchange coils are the largest and most easily damaged components in the AHU, playing a crucial role in removing heat and humidity. The cleanliness of the heat exchange coil surface is directly related to its heat exchange efficiency, and insufficient cooling capacity directly impacts the comfort and process stability of the application. Regular coil cleaning and leak repair can extend its service life and improve the performance and efficiency of the air conditioning system.

[0005] The cleaning and maintenance of the coil requires a suitable operating space. Traditional air handling units (such as Figure 1 The coils (as shown) are fixed within the enclosure and are typically cleaned within the enclosure. This requires maintenance clearances upstream and downstream of the heat exchanger, which increases equipment length, floor space, and costs. In situations where these are inadequate, users often forgo maintenance, shortening equipment life. Coil replacement requires disassembly of the surrounding fixed components and enclosure, making maintenance more difficult and often requiring major overhauls. Utility Model Content

[0006] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a roller slide device for side extraction of the coil, which is more flexible when replacing the coil and convenient for extracting the coil, while ensuring that the channel opening does not leak air and condensation during normal use of the heat exchange coil.

[0007] The purpose of the utility model is achieved through the following technical solutions: this roller-type slide device for side withdrawal of the coil is arranged on the box body of the unit, and includes a sliding frame, a heat exchange coil and a thermal insulation cover plate. Side panels are provided on both sides of the box body, and a pull-out groove is provided on one of the side panels. The sliding frame is fixedly installed at a position corresponding to the pull-out groove in the box body. One end of the heat exchange coil is inserted into the pull-out groove and installed on the sliding frame in a relatively sliding manner. The other end of the heat exchange coil is provided with a collecting pipe. The thermal insulation cover plate is installed after the collecting pipe passes through the pull-out groove. The thermal insulation cover plate is detachably connected to the side panel, which is convenient for the installation and disassembly of the heat exchange coil.

[0008] As a further technical solution, a roller chassis is fixed on the bottom plate of the box body at a position corresponding to the heat exchange coil. When the heat exchange coil slides relative to the sliding frame, the bottom of the heat exchange coil is slidably supported on the roller chassis.

[0009] As a further technical solution, the roller chassis includes a water tray and a water tray bracket fixed to the bottom of the water tray. Several supporting blocks are symmetrically provided on the inner walls on both sides of the water tray for supporting the rolling shaft. Fixed pads are provided at the front and rear ends of the water tray.

[0010] As a further technical solution, a groove is provided on the support block, and a shaft core is provided at the center of the rolling shaft, and both ends of the shaft core are embedded in the corresponding grooves on the support block.

[0011] As a further technical solution, the sliding frame includes vertical square tubes fixed along the vertical direction of the box body and vertical square tubes fixed perpendicularly to the side panel. The vertical square tubes are located on both sides of the heat exchange coil, and the heat exchange coil and the vertical square tubes are slidably connected by guide rails.

[0012] As a further technical solution, the guide rail includes a fixed end mounted on the surface of the vertical square tube and a movable end mounted on the side plates on both sides of the heat exchange coil, and the movable end is embedded in the fixed end.

[0013] As a further technical solution, locking screws are provided on the four corners of the thermal insulation cover plate, and corresponding screw holes are provided on the side panels around the pull-out groove.

[0014] The beneficial effects of the utility model are:

[0015] 1. Easy to operate. The slide roller mechanism enables the coil to be pulled out and pushed in flexibly and conveniently without disassembling other parts, which greatly improves the convenience of operation.

[0016] 2. Easy maintenance. The coil can be easily pulled out of the equipment, making it easy to clean, repair and replace, reducing maintenance costs.

[0017] 3. Compact structure. The slide design can optimize the internal structure of the equipment, making the entire system more compact and space-saving;

[0018] 4. Safe and reliable, the locking mechanism and sealing connection parts ensure the stability and safety of the coil during operation, preventing medium leakage and safety accidents;

[0019] 5. The guide rail is made of wear-resistant and corrosion-resistant materials and does not require maintenance after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS
