Application of stainless steel capillary: signal tube of automation instrument, wire protection tube of automation instrument; Precision optical ruler circuit, industrial sensor, electronic equipment circuit protection tube; Safety protection of electrical lines, protection of thermal instrument capillaries and internal support of air core high-voltage optical cables.

Characteristics of stainless steel capillary: it has good flexibility, corrosion resistance, high temperature resistance, abrasion resistance, tensile strength, water resistance and provides excellent electromagnetic shielding performance. The stainless steel hose can be freely bent into various angles and radii of curvature, and has the same flexibility and durability in all directions; The pitch of stainless steel hose is flexible, with good flexibility, without blocking and stiffness; Between the side buckles of each section of stainless steel threading hose

It has certain tensile resistance to prevent the line laid inside the hose from being exposed due to the damage of the hose. The axial tensile force can withstand more than 6 times of the nominal inner diameter.

The capillary network simulates the mechanism of leaf veins and human capillaries. It is composed of capillaries with an outer diameter of 3.5-5.0mm (wall thickness of about 0.9mm) and main water supply and return pipes with an outer diameter of 20mm (wall thickness of 2mm or 2.3mm). The thermal insulation layer, the heat dissipation layer and the capillary net are combined to form a capillary net heat exchanger, which greatly improves the heat dissipation ability of a single structure of the capillary net and its use purpose, and protects the capillary tube wall from damage. The capillary network planar radiation air conditioning system generally adopts the small circulation and large system mode, and uses a special solution as the medium, which can avoid system blockage and facilitate control. In order to achieve higher comfort requirements and avoid condensation, the room should also be equipped with humidity control and fresh air system. The production and application technology of capillary network has been highly monopolized by German enterprises before. Beijing plave Environmental Technology Co., Ltd. has broken the monopoly of foreign enterprises, developed and produced domestic capillary network heat exchangers, applied for a number of invention patents and utility model patents, and has entered the stage of mass production. In May 2007, the product was tested in the air conditioning Institute of China Academy of Building Sciences (national air conditioning equipment grain purchase supervision and inspection center). Taking the test of a node as an example, the results are as follows: 1. There is no leakage when the experimental pressure is 1.5MPa; 2. When the water supply temperature is 45 ℃, the return water temperature is 40 ℃, the reference temperature is 20 ℃, and △ t = 22.5 ℃, the heat dissipation per unit area of the sample is QDR = 240.88w/m2; 3. When the water supply temperature is 15 ℃, the return water temperature is 20 ℃, the reference temperature is 26 ℃, and △ t8.5 ℃, the refrigerating capacity per unit area of the sample is QDL = 122.84w/m2.
