▎ 摘　　要

NOVELTY - The device comprises a heat insulating box body whose top portion is adhered with a device cover plate (2). The top portion of the heat insulation box body (1) is welded and fixed with a mounting base. The bottom of the mounting base is provided with a bearing seat (4). The outer bearing of the bearing seat is connected with an electric telescopic rod (8). The one side of the electric telescope rod is set with a side direction pull rod. The output end of the electrical telescopic rods is connected to the outer side of a lifting force arm (5). A lower bolt of the lifting arm is fixed with the device box body. The inner portion of a heat insulation tank is arranged with a heating structure box. USE - Graphene heating efficiency testing device for commercial heating device, such as central air conditioner and heating used in house. ADVANTAGE - The device is convenient for gathering operation to the speed of the heat conduction using the detecting electric couple to detect multiple points of the graphene plate of the rectangular structure, using the electromagnetic iron sheet to absorb and clamp the two sides of the heating structure box, on one hand, avoiding the heat structure box swinging in different directions and testing process, on the other hand, improving the flexibility of the building structure box in the assembling process. The hook sheet and the clamping groove are connected by the spring to clamp and fix the graphene plates at the other two sides, convenient for clamping and fixing graphene plates with different widths. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a graphene heating efficiency testing device for commercial heating device detection.
