Description

Technical Field

[0001] The utility model belongs to the technical field of powder coatings, and in particular relates to a device for detecting the heat dissipation performance of powder coatings. Background Art

[0002] At present, there is a demand for heat dissipation in many fields such as 3C, new energy batteries, wires and cables, etc. The thermal radiation coefficient of the test material can be considered to detect the heat dissipation performance. However, in actual applications (such as the cables inside the pipeline will generate heat during power-on operation, and the external pipeline needs to dissipate heat), the surfaces of these objects are usually coated with powder coatings, and it may be necessary to detect the actual temperature of the outer wall of the workpiece at a fixed temperature. Therefore, the thermal radiation coefficient cannot accurately describe the actual application scenario.

[0003] The patent number is 201921812611.0, and a public specification published on October 27, 2019 discloses a detection device for comparing the heat dissipation performance of coatings, which relates to the technical field of coating production equipment. The detection device for comparing the heat dissipation performance of coatings includes a detection box and a thermometer located on one side thereof. The top of the detection box is rotatably connected to a box cover by a hinge, and an insulation layer is bonded to the inner wall of the detection box. An electric heating wire is fixed at the middle position inside the detection box, and heat conducting plates are symmetrically arranged on both sides of the electric heating wire inside the detection box. The thermometer is connected to one side of the detection box adjacent to the detection box with two connecting cables that penetrate into the interior of the detection box. The utility model utilizes the funnel-shaped mounting groove and the arc groove opened inside the mounting plate to receive the fallen paint powder residue, thereby preventing the paint powder residue from falling into the device, thereby effectively reducing the difficulty of cleaning the detection device and helping to reduce the workload of the detection personnel.

[0004] In the above-mentioned prior art, the structure for detecting the heat dissipation performance is relatively complex and inconvenient to operate, and the detection scenario does not fit the actual application scenario of the powder coating, which causes inaccurate measurement results.

[0007] Both ends of the cylinder are provided with a heat-insulating bottom plate and a cylinder cover.

[0008] The heat-insulating bottom plate is a circular asbestos base, and a slot matching with the cylinder is arranged on the heat-insulating bottom plate.

[0009] A top temperature sensor is arranged on the cylinder cover.

[0010] The heating device is an installation cylinder arranged at the center of the circle of the cylinder or a group of installation cylinders distributed in a circumferential manner with the center of the circle of the cylinder as the center.

[0011] The heating device is connected with a PID temperature control device.

[0012] The cylinder is an aluminum cylinder with a thickness of 0.5 - 3 mm.

[0013] The heat-insulating bottom plate is an asbestos heat-insulating circular ring plate.
