Description

Technical Field

[0001] The utility model relates to the field of heat exchange tubes, in particular to a lightweight condenser tube. Background Art

[0002] With the rapid development of refrigeration and air conditioning technology, the design of condenser tubes has also been continuously updated. The working principle of a condenser tube is as follows: a low-temperature fluid, typically water, flows inside the tube; a gaseous refrigerant flows outside the tube. Upon contact with the tube wall, the gaseous refrigerant undergoes a phase change, forming a condensed liquid, which releases latent heat and exchanges heat with the low-temperature fluid inside the tube.

[0003] Existing condensers are typically made of copper, which is heavy, making the equipment very heavy after the condenser is installed. In addition, existing condenser tubes are processed separately by machining the inner and outer walls, which requires thicker tube walls, further increasing the weight of the condenser. Utility Model Content

[0004] In view of the defects of the above-mentioned prior art, the main purpose of the present invention is to overcome the shortcomings of the prior art and discloses a lightweight condenser, including a tube body, external teeth and recesses arranged on the outer surface of the tube body, and a protrusion arranged on the inner wall of the tube body, wherein the protrusion corresponds to the position of the recess.

[0005] Furthermore, the protrusion is a conical structure.

[0006] Furthermore, the outer teeth are provided with through grooves along their axial directions.

[0007] Furthermore, the middle of the tube body is made of aluminum, and the upper surface and lower surface of the tube body are covered with copper.

[0008] Beneficial effects achieved by this utility model:

[0009] By providing corresponding notches and protrusions, this new design reduces tube wall thickness and machining margins through structural changes, thereby lightweighting the condenser tube. The tube body features an aluminum core wrapped in copper, ensuring corrosion resistance while also achieving lightweighting. Axial grooves are provided through the outer teeth, forming independent fins that increase contact area and facilitate separation of liquid refrigerant. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] A lightweight condenser, such as Figure 1-Figure 2 As shown, it includes a tube body 1, external teeth 11 and recesses 12 provided on the outer surface of the tube body 1, and a protrusion 13 provided on the inner wall of the tube body 1, and the protrusion 13 corresponds to the position of the recess 12. By setting the protrusion 13 and the recess 12 to corresponding positions, the outer wall of the tube body 1 can be extruded to form the recess 12 and the protrusion 13 at the same time, and the internal protrusion 13 serves to increase the contact area of ​​the tube body 1 with the low-temperature fluid, thereby promoting heat exchange. The external teeth 11 and recesses 12 on the outer surface of the tube body 1 can greatly increase the contact with the refrigerant, and then the contact area with the refrigerant, further promoting heat exchange. At the same time, because it can be achieved by extrusion processing, the thickness of the tube body 1 can be thinned, thereby achieving lightweighting of the condenser.

[0016] In one embodiment, if Figure 1-Figure 2 As shown, the protrusion 13 is a conical structure. The conical structure can reduce the resistance to the circulation of the low-temperature fluid.

[0017] In one embodiment, if Figure 1-Figure 2 As shown, the outer teeth 11 are provided with through grooves 14 along their axial direction. The provision of the grooves 14 enables the outer teeth 11 to form independent fins, further increasing the contact area and promoting the separation of the liquid refrigerant from the tube body 1.

[0018] In one embodiment, if Figure 1-Figure 2 As shown, the middle of the tube body 1 is made of aluminum, and the upper and lower surfaces of the tube body are covered with copper. Copper has good corrosion resistance, while aluminum is lightweight. The above structure achieves lightweight condenser.

[0019] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Without departing from the spirit and scope of the present invention, modifications or equivalent replacements of the present invention should be included in the scope of protection of the claims of the present invention.
