Control system of heat transfer effect testing device and use method thereof

Abstract

The invention relates to a control system of a heat transfer effect testing device and a use method thereof. A lower chamber is placed on a chassis, a heating element, a cold source radiator and a fan are arranged in the lower chamber, a heat channel is formed in the center of a middle heat insulation layer, a sample corner and a straight section positioning plate are arranged on the middle heat insulation layer, and two sensors on a sample are mounted at the lower end of an inverted-U-shaped frame; the middle part of a swinging rod is connected with a stretch spring and an electric cylinder B, and the top of an upper chamber is provided with a movable plate; and vertical sliding sleeves are welded to the four corners of the movable plate, sliding bars penetrate through the sliding sleeves, the lower ends of the sliding bars are fixed to the chassis, horizontal plates are fixed to the upper ends of the sliding bars through nuts, holes are formed in the centers of the horizontal plates, telescopic cylinders A are inserted into the holes, and the lower ends of the telescopic cylinders A are connected with the movable plate. According to the scheme, automation of the detection process is achieved, and the detection quality and efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of a heat transfer test device control system, in particular to a control system and a use method of a heat transfer effect test device. Background technique [0002] In order to meet the high demand of consumers and improve the performance of products, it is necessary to test the heat transfer effect of various materials. The current principle of testing the heat transfer performance of materials is to transfer constant heat energy from the lower surface of the material specimen to the upper surface. The ratio of the temperature value to the time taken for the surface temperature to stabilize. [0003] However, at present, the detection of the heat transfer effect of materials is mostly manual operation, calculation, and judgment, and there are problems of human interference factors and low detection quality and low efficiency. Moreover, some test devices on the market also have the defect of low detection...

[0003] However, at present, the detection of the heat transfer effect of materials is mostly manual operation, calculation, and judgment, and there are problems of human interference factors and low detection quality and low efficiency.

Moreover, some test devices on the market also have the defect of low detection quality due to the low control accuracy of each component of the equipment.
