preparation example Construction

[0030] According to another aspect of the present invention, a method for preparing a capillary assembly is provided, including the steps of preparing a capillary, melting a hot melt adhesive, dipping the capillary, and curing. Figure 4 One process flow for preparing a capillary assembly is shown. The preparation method is simple, easy to operate, does not need large instruments and other equipment, and only needs manual dipping to meet the requirements of the capillary assembly of the present invention.

[0031] Preferably, the step of preparing the capillary includes: forming a helically coiled capillary bending portion 11 and a capillary straight portion 12 formed by parallel extension of two ends of the capillary bending portion 11; the step of melting the hot melt adhesive includes: The melt adhesive is heated in a temperature-controllable container to obtain a molten hot melt adhesive. The use of such a temperature-controllable container is beneficial to control the vi...

Embodiment 1

[0037] Put the solid hot-melt adhesive into a temperature-controllable container and heat until the viscosity of the molten hot-melt adhesive is 2500cps. Hold the straight part of the capillary and slowly immerse 1 / 2 of the bent part of the capillary into the molten hot-melt adhesive to keep 1 second. Slowly take out the bent part of the capillary from the molten hot melt adhesive and turn it over in the radial direction of the bent part of the capillary, put the capillary in the air to solidify, and obtain a capillary with a hot melt adhesive coating on the surface.

Embodiment 2

[0039]The preparation method is the same as that in Example 1, except that when the viscosity of the molten hot melt adhesive is 3500 cps, the bent part of the capillary is immersed for 2 seconds.

Abstract

The invention discloses a capillary tube component and a preparing method thereof. The capillary tube component comprises a capillary tube and a hot melt adhesive coating layer arranged on the surface of the capillary tube. The hot melt adhesive coating layer is arranged on the surface of the capillary tube to protect the capillary tube, so that the problem about abnormal sound generated by the capillary tube of an air conditioner is solved effectively, noise level generated among the capillary tube and other parts is lowered, requirements on reliability, safety and comfortability of the air conditioner are met, and national standards are conformed to.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a capillary component and a preparation method thereof. Background technique [0002] In modern human life, the use of air conditioners has become very common. However, during the use of the air conditioner, the capillary in the refrigeration system of the air conditioner not only produces noise when it cools itself, but also collides with other parts of the air conditioner to generate abnormal noise. Especially in small air conditioners, when the air conditioner is running, the capillary will contact and rub against other parts, and if this happens for a long time, the capillary will wear out, which will seriously affect the service life of the air conditioner. But the way that takes at present generally is to adopt the mode of binding and sticking sponge to solve. Such as figure 1 as shown, figure 1 A schematic diagram of the structure of the sponge wrapped on the surface of...
