Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] image 3 It is a sectional view of the elbow for secondary throttling of the present invention.

[0031] Such as image 3 As shown, the shape of the elbow 6 of the present invention is "U" shape, and a plurality of through holes 7 are arranged inside it. The through holes 7 are arranged side by side. In order to achieve the purpose of throttling, the through hole 7 must be thin, similar to a capillary. The number of capillary-shaped through-holes 7 is determined according to throttling requirements, and the number of through-holes 7 is set to five in this embodiment. In order to achieve the original throttling effect, the lengths of all the through holes 7 in the "U" shape must be added together to reach the original length of the capillary 4. In order to transfer heat better, the present invention adopts a round copper material with good he...

Abstract

The invention discloses an elbow used for a second time throttling of an air conditioner, belonging to an air conditioner component provided with a capillary structure used for leading to changes of flow channel sections so as to change a heat transmission state. The second time throttling elbow of the invention adopts a round copper material bent into a U shape. A plurality of parallel capillary-shaped through holes are arranged in the U-shaped material. The length of all the through holes is equal to that of the prior capillary structure. The outer diameter of the U-shaped copper material is equal to that of a connecting tube. The second time throttling elbow of the invention is arranged on the side of an evaporator. Compared with the original capillary structure, the invention has a small-volume elbow with the same appearance as the connecting tube, a bigger weight and a simple structure, is shaped by one time, and can save space and lead to convenient manufacturing process without cold medium leakage and noise.

Description

technical field [0001] The invention relates to an element in an evaporator of an air conditioner that changes heat transfer by having a capillary structure to cause a change in the cross section of a flow channel, in particular to an elbow used for secondary throttling of the air conditioner. Background technique [0002] Generally speaking, air conditioners create a more comfortable indoor environment through cooling or heating operations, and can be roughly divided into integrated air conditioners and split air conditioners. The integrated air conditioner and the split air conditioner are basically the same in function. The integrated air conditioner integrates the functions of cooling and heat release, and punches holes in the indoor wall or directly installs it on the window with the device; A cooling device is installed indoors, and a heat release and compression device is installed outdoors, and the two separate devices are connected by refrigerant conduits.
