The subject matter herein generally relates to refrigeration equipment, and more particularly to a noise reduction device in refrigeration equipment.
Generally, refrigeration equipment such as a refrigerator uses refrigerant liquid. The refrigerant liquid is cycled between a gaseous phase and a liquid phase. The refrigerant liquid may produce noise during transition between the gaseous phase and the liquid phase.
Implementations of the present disclosure will now be described, by way of embodiments only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
The noise reduction device 15 includes at least one transition tube through which the refrigerant liquid flows from the capillary 14 to the evaporator 16. A diameter of the at least one transition tube gradually increases from the capillary 14 to the evaporator 16. The gradually increasing diameter of the transition tube reduces a speed of flow of the refrigerant liquid from the capillary 14 to the evaporator 16, thereby preventing a sputtering noise caused by a speed of flow of the refrigerant liquid being too fast from the capillary 14 to the evaporator 16. Referring to
In the first embodiment, a length of the first transition tube 151 is equal to a length of the second transition tube 152. For example, the length of the first transition tube 151 is 140 mm, and the length of the second transition tube 152 is 140 mm.
In the first embodiment, the damping adhesive 154 covers over a connecting joint between the first transition tube 151 and the capillary 14 and a connecting joint between the second transition tube 152 and the evaporator 16. In other embodiments, the damping adhesive 154 covers from the connecting joint between the first transition tube 151 and the capillary 14 to the connecting joint between the second transition tube 152 and the evaporator 16.
In the first embodiment, the first transition tube 151 is coupled to the capillary 14 by welding, and the second transition tube 152 is coupled to the evaporator 16 by welding. In other embodiments, the first transition tube 151 may be coupled to the capillary 14 by other means, such as by screwing, and the second transition tube 152 may be coupled to the evaporator 16 by other means, such as by screwing.
In the first embodiment, the first transition tube 151, the coupling portion 153, and the second transition tube 152 are integrally formed. In other embodiments, the first transition tube 151, the coupling portion 153, and the second transition tube 152 are coupled together by welding or by other means.
In the first embodiment, the first transition tube 151, the second transition tube 152, and the coupling portion 153 are made of copper. In other embodiments, the first transition tube 151, the second transition tube 152, and the coupling portion 153 may be made of stainless steel or other material.
In the first embodiment, inner walls of the first transition tube 151, the second transition tube 152, and the coupling portion 153 are smooth.
In the first embodiment, an end portion 1521 of the second transition tube 152 coupled to the evaporator 16 is a rounded connecting joint. In another embodiment, an end portion of the first transition tube 151 coupled to the capillary 14 may also be a rounded connecting joint.
In other embodiments, the noise reduction device 15 may include more than two transition tubes, such as shown in
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
