A kind of testing equipment for thermal insulation performance of doors and windows

Abstract

The invention discloses a test device for the thermal insulation performance of doors and windows, which comprises a main body, a heating area, a normal temperature area and a cooling area. The heating area, the normal temperature area and the cooling area are arranged in sequence from left to right inside the main body. The main body is composed of a cooling fan control switch and a heat insulation layer. The heat insulation layer is arranged outside a shell. A heating rod is fixedly connected to the middle inner surface of the heat insulation layer at the top of the heating area. A cooling fan is fixedly arranged on the middle inner surface of the heat insulation layer at the top of the cooling area. A buffer block is arranged at the bottom of the heat insulation layer and right below adoor and window entrance. Second fixed plates are symmetrically arranged at the left and right ends of the top of the buffer block. The lower ends of the second fixed plates are fixedly connected withthe bottom inner surface of the heat insulation layer. The test device has a simple structure. The temperature difference of the heating area, the normal temperature area and the cooling area can beclearly known through a display screen, and the thermal insulation performance of doors and windows can thus be known. Moreover, doors and windows with different thickness can be fixed conveniently, efficiently and stably.

Description

technical field [0001] The invention relates to the technical field of testing equipment for the thermal insulation performance of doors and windows, in particular to testing equipment for the thermal insulation performance of doors and windows. Background technique [0002] With the development of the times, people's living standards are constantly improving. As a new type of high-end building envelope, glass curtain walls are widely used in multi-story and high-rise buildings. However, due to the nature and characteristics of the materials used, energy consumption And safety performance has always been two major problems that plague the development of curtain walls, which requires testing the physical properties of glass curtain wall products; the thermal insulation and sunshade performance of external doors and windows of buildings is an important indicator for evaluating whether a building is energy-efficient or not, and the thermal insulation performance testing of exter...

Problems solved by technology

[0003] However, the existing detection boxes are often only suitable for one type of doors and windows. In real life, doors and windows of different thicknesses abound, and the operation of doors and windows in and out of the detection box is cumbersome, and friction may cause the surface of the doors and windows to wear. The final heat and cold air cannot be collected, resulting in energy waste
