Description

Technical Field

[0001] The utility model relates to a heat exchanger, mainly a down-blowing fin-type heat exchanger structure. Background Art

[0002] With the emergence of new economies, new industries, new demands, and the continuous development of industrial modernization, air conditioning has been widely used. Among them, air source heat pump units are energy-saving devices that use fans and fins to convert large amounts of low-temperature heat energy / high-temperature heat energy in the air into high-temperature heat energy / low-temperature heat energy through compressors.

[0003] Currently, most finned heat exchangers produced by air source heat pump manufacturers on the market use a top-blowing system, where air enters from the side of the heat exchanger and exits from the top. This requires sufficient top-mounted space when installing the unit. If the unit is installed indoors, space utilization is low.

[0004] Based on the above, a down-blowing finned heat exchanger structure was designed, which solved the problem of insufficient heat exchange of the heat exchanger caused by uneven air intake of the down-blowing finned heat exchanger, and the space utilization rate was higher when the unit was installed indoors.

[0007] Furthermore, the sides of the flow equalizing orifice frame assembly are respectively fixedly connected to the flow equalizing sealing plate, flow equalizing orifice A, flow equalizing orifice B and flow equalizing orifice C. The flow equalizing orifice A and flow equalizing orifice B are spaced apart from each other and symmetrically form a V-shaped structure.

[0008] Furthermore, the flow equalizing box assembly includes a flow equalizing box bottom plate, and the flow equalizing box bottom plate and symmetrically arranged flow equalizing box side plates A and B form a frame structure. The flow equalizing box middle plates arranged at intervals divide the frame structure into two parts. The flow equalizing box bottom plate of each part is provided with a through hole for connecting with the upper opening of the flow equalizing orifice plate frame assembly.

[0009] Furthermore, the coil fixing plate is fixedly connected to the long upper beam by screws, one side of the short upper beam is fixedly connected to the flat side of the long upper beam, and the bent edge on the other side is on the inner side of the sealing plate and fixed with screws.

A flow equalizing box assembly is provided above the coil assembly A1 and the coil assembly B2, and the axial flow fan 17 is fixed on the flow equalizing box assembly; a water pan assembly 3 is provided below the coil assembly A1 and the coil assembly B2, and the bottom of the coil assembly A1 and the coil assembly B2 are fastened to the water pan assembly 3 by bolts to make the two coil assemblies symmetrical on the left and right, and the middle parts of the coil assemblies on both sides are connected and fixed by a sealing plate 13. The inner sides of the coil assembly A1 and the coil assembly B2 are provided with a flow balancing orifice plate and a flow balancing orifice plate frame assembly 12. The air blown out by the axial flow fan 17 arranged on the top is blown evenly to the surface of the coil assembly A1 and the coil assembly B2 through the flow balancing orifice plate.

[0022] The sides of the equalizing orifice frame assembly 12 are respectively connected to the equalizing sealing plate 13, the equalizing orifice A14, the equalizing orifice B15 and the equalizing orifice C16 by pre-drilling holes and fastening screws. The equalizing orifice A14 and the equalizing orifice B15 are arranged at intervals up and down and symmetrically form a V-shaped structure. Figure 5 As shown, the flow equalizing sealing plate, flow equalizing orifice plate A, flow equalizing orifice plate B, and flow equalizing orifice plate C are connected to the flow equalizing orifice plate frame assembly through the openings between each other using screws, and are fastened to the bottom plate of the flow equalizing box by screws.

[0023] like Figure 4As shown, the flow equalizing box assembly includes a flow equalizing box bottom plate 8, which is surrounded by symmetrically arranged flow equalizing box side plates A9 and flow equalizing box side plates B10 to form a frame structure. The flow equalizing box middle plates 11 arranged at intervals divide the frame structure into two parts. The flow equalizing box bottom plate 8 of each part is provided with a through hole for communicating with the upper opening of the flow equalizing orifice frame assembly 12. During installation, the flow equalizing box bottom plate 8 is fixed to the flow equalizing box side plates A9 and the flow equalizing box side plates B10 on both sides with screws, and one side of the flow equalizing box middle plate 11 is fastened to the flow equalizing box side plate A9 with bolts, and the other side is fastened to the flow equalizing box bottom plate 8 with screws. Finally, the flow equalizing box side plate A9 on the other side is installed. When connecting the sheet metals, butyl glue must be affixed and the gaps must be treated to prevent leakage.

[0024] like Figure 2-Figure 3 As shown, the coil fixing plate 6 is fixedly connected to the long upper beam 4 by screws, one side of the short upper beam 5 is fixedly connected to the plane side of the long upper beam 4, and the bent edge of the other side is fixed on the inner side of the sealing plate 18 with screws, and the flow equalizing box support plate 7 is flush with and centered on the top of the long upper beam 4, and the two ends are fastened to the long upper beam 4 with screws.

The assembled flow equalizing box assembly is fastened to the long upper beam 4 and the short upper beam 5 by screws. The bent plane of the assembled flow equalizing orifice plate assembly is fastened to the flow equalizing box bottom plate 8 by screws, and the two flow equalizing orifice plate assemblies are symmetrical on the left and right, and the flow equalizing sealing plate 13 is close to the sealing plate 18.

[0025] Installation process: First, fix the coil assembly and the coil fixing plate with fasteners, then fix the coil assembly and the water pan assembly with fasteners, and then fix the sealing plate, long upper beam, short upper beam, and flow equalizing box support plate in sequence. During this period, assemble the flow equalizing box assembly and the flow equalizing box orifice frame assembly, then install and fix the flow equalizing box assembly, and fix the flow equalizing orifice frame assembly to the flow equalizing box assembly, and finally fix the axial fan to the flow equalizing box assembly with fasteners. The utility model is designed to be a down-blowing fin heat exchanger structure, and can ensure that the wind blows evenly to the surface of the fin heat exchanger, avoiding the problem of uneven fin heat exchange. At the same time, the down-blowing design has a much smaller installation space on the top than the traditional up-blowing design, so the unit is directly installed indoors, and the heat exchange of the heat exchanger will not be affected by the low floor height.

[0026] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
