Description

Technical Field

[0001] The utility model relates to the technical field of air handling units, in particular to an anti-cold bridge box body of an air handling unit for nuclear power plants. Background Art

[0002] The air conditioning fan box is a device used for the installation of air conditioning fans. It protects and supports the air conditioning fans and also has the effects of preventing cold bridges and keeping warm.

[0003] The utility model with the existing announcement number CN215255359U discloses a quick-install anti-cold bridge air conditioner fan case, which includes a tee, a frame strip, a silicone rubber sealing strip, a panel, and a panel lock. The frame strip is integrated with a pair of lining plates of the same length as the frame strip at the corners of the pipes inside the case. A silicone rubber sealing strip is provided between the lining plates and the panel. The panel lock includes a handle limited to the outer side of the panel and a rotating lock tongue limited to the inner side of the panel and rotates and locks the lining plate when the handle is turned. The side of the lining plate opposite the panel is provided with a sealing groove extending along the sealing length. The main body of the silicone rubber sealing strip is a soft sealing sleeve with a length greater than or equal to the length of the sealing groove. The side of the soft sealing sleeve is integrated with an insert that fits tightly with the sealing groove. When the panel and the lining plate are squeezed relative to each other, the soft sealing sleeve deforms to seal the gap between the panel and the lining plate.

[0004] During actual use of the above device, due to the integrated structure of the metal parts inside and outside and the rapid heat conduction characteristics of metal, the temperature inside the box will be lost quickly, resulting in uneven temperature inside the box. For this reason, we propose an anti-cold bridge box for air handling units for nuclear power plants. Utility Model Content

By placing the box frame on the outer wall of the box and not contacting the box, the temperature loss inside the box is effectively reduced and the thermal insulation of the box is improved.

[0008] The beneficial effects of the present invention are as follows: by placing the box frame on the outer wall of the box without contacting the box, the temperature loss inside the box is effectively reduced, the thermal insulation of the box is improved, and condensation or dew condensation on the surface of the box due to temperature difference is avoided.

[0009] The utility model facilitates the disassembly of the plates by cooperating with each other through the dovetail block and the dovetail groove of the first splicing plate and the second splicing plate. BRIEF DESCRIPTION OF THE DRAWINGS
