A kind of airtight insulation box

Abstract

The invention relates to the technical field of heat insulation, in particular to an airtight heat insulation box. The airtight heat insulation box comprises twelve skeletons, eight corner pieces and six box plates. The skeletons are inserted into the corner pieces. The box plates are used for covering the six surfaces of a framework. The skeletons are hollow. A right-angle groove is formed in the inner side of each skeleton. A rectangular groove is formed in the bottom of each right-angle groove. Embedment strips are arranged in the right-angle grooves. Protruding strips are arranged outside the embedment strips and clamped into the rectangular grooves. A first trapezoid notch and a second trapezoid notch are formed in the inner side of each embedment strip and overlap each other. Angle aluminum pieces are arranged on the inner sides of the embedment strips. Two symmetrical clamping strips are arranged on the outer side surface of each angle aluminum piece, and the clamping strips are clamped into the first trapezoid notches. Two installation grooves are formed close to the outer side face of each skeleton and located in the two sides of the corresponding right-angle groove respectively. A pressing strip is arranged in each installation groove. The box plates are arranged between the pressing strips and the angle aluminum pieces.

Description

technical field [0001] The invention relates to the technical field of heat preservation, in particular to an airtight heat preservation box, which is widely used in air conditioners, dehumidifiers and other equipment shells that require heat preservation and sealing. Background technique [0002] The cold bridge mainly refers to the heat transfer coefficient of some parts of the building envelope structure is obviously larger than other parts when the cooling or heat is conducted between the building envelope and the outside world, so that the cold or heat is concentrated from these parts. Rapid transmission, thereby increasing the building's air conditioning, heating load and energy consumption. In the air-conditioning and HVAC industry, cold bridge usually refers to the phenomenon that the large temperature difference of low or high temperature inside the air conditioner is conducted to the outside through components with poor thermal insulation. The cold bridge makes th...

Problems solved by technology

In today's trend of advocating energy saving, low-carbon, green and environmental protection as the main theme, cold bridges have always been a practical problem that plagues the air-conditioning industry. At the same time, the constant-temperature and high-humidity air flow inside the air conditioner brings bacteria and viruses into the air, which is also an important factor that causes air-conditioning diseases. Solve An important solution to these problems is cleaning and maintenance. Existing products have complex structures, difficult installation and manufacturing, and internal maintenance and cleaning of later equipment, poor sealing performance, and rough appearance.
