[0001] The utility model relates to the technical field of air-conditioning terminals, and in particular to an ultra-thin cabinet-type fan disc unit. Background Art

[0002] The cabinet fan coil unit is an air handling device used in the terminal series of central air conditioners. The unit itself does not have a cold or heat source. The cold (hot) water entering the heat exchanger exchanges heat with the indoor circulating air or outdoor fresh air to cool the air, heat it, dehumidify it, dry it, filter it, and purify it. The treated air is then transported to each air-conditioned area through the air duct to achieve the purpose of air conditioning.

[0003] However, the cabinet-type fan tray units currently used in the industry include a unit base frame, a unit casing, a unit fan components, a water collection tray, a coil, etc. For units with specific lifting heights, the thickness of the unit base frame-related structures will increase, making it difficult to meet the lifting requirements for the entire unit height.

[0004] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned shortcomings and provide an ultra-thin cabinet type fan tray unit.

[0027] The supporting mechanism includes a unit bottom plate 5 arranged on the same mounting surface of the direct-connected fan 1, the coil assembly 2, and the water tray assembly 3 and perpendicularly intersecting with the vertical surface where the filter 4 is located, and an inspection panel 6, an air outlet panel 8, and a fixed panel 7 arranged on the remaining three sides of the unit bottom plate 5 and connected in sequence, which are used to fix and support the direct-connected fan 1, the coil assembly 2, and the water tray assembly 3. In this design, the unit bottom plate 5 connected by screws at the bottom of the filter 4 included in the cabinet fan tray unit, and the inspection panel 6, the air outlet panel 8, and the fixed panel 7 are sequentially fixed on the remaining three sides of the unit bottom plate 5 by means including but not limited to welding, to form a closed area, to fix and support the direct-connected fan 1, the coil assembly 2, and the water tray assembly 3 included in the cabinet fan tray unit, and prevent the direct-connected fan 1, the coil assembly 2, and the water tray assembly 3 from deviating inside.

[0028] It should be noted that the direct-connected fan 1 is connected to the coil assembly 2, and the direct-connected fan 1 blows air through the coil assembly 2 by supplying air to achieve heat exchange of the air.

[0029] It should be noted that the coil assembly 2 is connected to the water tray assembly 3, and the coil of the coil assembly 2 is connected to the water tray assembly 3 through a water supply pipeline.

[0030] It should be noted that the filter 4 is connected to the air inlet of the direct-connected fan 1 to filter dust and impurities in the air.

[0031] It should be noted that the unit bottom plate 5 is formed by composite pressing of a reinforced outer plate and an inner plate. The outer plate is made of a polyurethane foam plate and the inner plate is made of a 1.0 galvanized plate to increase the overall strength.

[0032] In one embodiment, the upper surface of the unit bottom plate 5 is provided with embedded rivet nuts 51 for fixing the direct-connected fan 1. In this design, the embedded rivet nuts 51 are fixed on the upper surface of the unit bottom plate 5 by means including but not limited to welding, and the embedded rivet nuts 51 are provided in a group of four, which can replace the fan bracket structure to fix the direct-connected fan 1, saving engineering space.

[0033] In one embodiment, the support mechanism further includes unit lifting ears 9 provided on both sides of the ends where the air outlet panel 8 and the unit bottom plate 5 are connected. In this design, the unit lifting ears 9 connected on both sides where the air outlet panel 8 and the unit bottom plate 5 are connected can replace the whole machine chassis support structure, effectively saving engineering use space and improving the efficiency of building space utilization.

[0034] In one embodiment, the air outlet panel 8 is provided with two symmetrically distributed air outlets 81 for communicating with the outside air. In this design, by symmetrically turning the two air outlets 81 on the air outlet panel 8, a channel can be established with the outside air, so that the inside and outside air are exchanged, meeting the use requirements of the whole machine.

[0035] In one embodiment, a shock absorber 10 is disposed on the outer portion of the upper end of the embedded rivet nut 51, and a through hole disposed on the central axis of the shock absorber 10 is disposed corresponding to the internal threaded hole provided on the embedded rivet nut 51. In this design, the shock absorber 10 sleeved on the embedded rivet nut 51 can provide shock absorbing and buffering protection for the direct-connected fan 1 in operation, which helps to extend the service life of the direct-connected fan 1.

[0036] It should be noted that the shock absorber 10 adopts a rubber structure.

[0037] In one embodiment, a fixing bolt 11 for fixing the direct-connected fan 1 on the surface of the unit bottom plate 5 is provided at the opening opened on the central axis of the shock absorber 10. With this design, by using the fixing bolt 11 to be rotatably fixed on the embedded rivet nut 51 on the surface of the unit bottom plate 5 on the central axis of the shock absorber 10 and at the upper end corner of the direct-connected fan 1, the whole machine realizes a fan-free bracket structure, effectively reducing the height size of the whole machine.

[0038] In one embodiment, the end faces of the unit lifting ears 9 that are in contact with the air outlet panel 8 and the unit bottom plate 5 are provided with self-tapping screws 12. In this design, the unit lifting ears 9 are fixed on both sides of the whole body by using self-tapping screws 12 to rotate and fix the end faces that are in contact with the air outlet panel 8 and the unit bottom plate 5, thereby realizing a non-bottom frame support structure, meeting the production requirements of the ultra-thin fuselage structure, satisfying the whole machine hoisting at a specific height, and improving the efficiency of building space utilization.

[0039] In one embodiment, a unit cover panel 13 for sealing the direct-connected fan 1, the coil assembly 2 and the water tray assembly 3 is provided above the unit bottom plate 5. With this design, the unit cover panel 13 is fixed on the top of the area included by the inspection panel 6, the air outlet panel 8 and the fixed panel 7 by a method including but not limited to welding, so that the direct-connected fan 1, the coil assembly 2 and the water tray assembly 3 can be sealed and isolated from the external environment.

[0040] It should be noted that the inner wall of the unit cover panel 13 is bonded with a thermal insulation layer to achieve an insulating and heat-insulating effect.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
