As a preferred scheme, in order to facilitate the flow of the polyurethane liquid and ensure the uniform foaming, the reinforcing beam is provided with a plurality of through holes.

As an optimal scheme, the upper plate of the mounting piece is provided with the rivet nut, and the inner plate is provided with a through hole corresponding to the rivet nut. When the unit frame is connected with the foaming panel, bolts can be used to penetrate through the through holes of the inner plate to be matched with the rivet nuts, so that the purposes of internally mounting the bolts and being attractive are achieved.

Preferably, the height of the inner plate is smaller than that of the outer plate, and the outer plate is buckled with the periphery of the inner plate. Preferably, the outer plate is provided with a material injection hole communicated with the inner space. The material injection hole is used for injecting polyurethane liquid material.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the utility model provides an air conditioning unit's foaming panel, simple structure through increase thermal insulation material between inner panel and planking, avoids forming the cold bridge, can reach fine heat preservation and sealed effect.

(2) The utility model discloses a set up installed part and stiffening beam on the planking, promote foamed polyurethane and connect into a whole between with the interior planking, increase the holistic intensity of foaming panel.
