Description

Technical Field

[0001] This utility model belongs to the field of heat transfer coefficient testing technology, specifically relating to a device for testing the heat transfer coefficient of building envelope. Background Technology

[0002] In the testing of the heat transfer coefficient of building envelope, heat flow meters and temperature sensors are currently installed on the surface of the building envelope (such as walls). They are usually manually attached to the surface with tape. However, over time, the rough surface can cause the adhesion to become unreliable. If there is an air gap between the sensor and the surface of the building envelope, it will affect the test results. In addition, if the sensor falls off during the test, it needs to be re-fixed, which will affect the test progress. Furthermore, the manual attachment with tape may also contaminate the surface of the building envelope and even cause the surface decorative layer to peel off.

[0003] In addition, in the past, when installing the test box, four sets of expansion bolts were needed to be drilled into the wall to be tested to suspend and fix the test box, and the nuts were used to tighten it to increase the sealing between the test box and the wall. However, this installation method would inevitably damage the test wall, and people would need to repair the wall after the test was completed.

[0004] Furthermore, traditional testing equipment is bulky, heavy, and inconvenient to operate on-site. In complex environments and poor road conditions, multiple people are needed to carry the equipment to the testing point, which is time-consuming and labor-intensive. In addition, the testing box of traditional testing equipment cannot be flexibly adjusted in height according to the site conditions, making it very difficult to select a site testing point that meets the installation requirements of the testing equipment. Testing cannot be carried out in places that do not meet the installation requirements of the testing equipment.

[0005] Currently, there is a lack of reliable and durable new equipment for testing the heat transfer coefficient of building envelopes, so that people can easily test the heat transfer coefficient of building envelopes.

[0006] Therefore, a new technology is needed to address the lack of a reliable and durable new device for testing the heat transfer coefficient of building envelopes in existing technologies. Utility Model Content
