Description

Technical Field

[0001] The utility model relates to the technical field of threaded copper tubes, in particular to a lightweight closely-toothed internal-thread copper tube. Background Technique

[0002] The internal-thread copper tube is a key heat transfer material for manufacturing evaporators and condensers in air conditioners. To improve the energy efficiency ratio of air conditioners, achieve the goal of air conditioner energy conservation, and effectively control the cost of air conditioner products, it is to increase the heat transfer amount per unit area of the heat exchanger, control its volume and mass, save materials, and increase the heat transfer coefficient. The heat transfer efficiency of the heat exchanger and the cost performance of the air conditioner are greatly related to the correct selection of the inner diameter of the internal-thread tube and the geometric parameters of the tooth shape.

[0003] Copper tubes, also known as red copper tubes, are a type of non-ferrous metal tubes, which are pressed and drawn seamless tubes. Copper tubes have the characteristics of good electrical conductivity and thermal conductivity. They are the main materials for conductive accessories and heat dissipation accessories of electronic products, and have become the first choice for modern contractors to install tap water pipes, heating, and refrigeration pipes in all residential commercial housing. Most heat transfer copper tubes will choose copper tubes with internal threads, and their thermal conductivity is better than that of ordinary smooth tubes, and the heat transfer performance is stronger.

[0004] However, for the existing high-efficiency and closely-toothed internal-thread copper tubes, during use, the structures of most internal-thread copper tubes are relatively simple. The ordinary threaded structure device mainly consists of a spiral ribbon, a bracket, a rotating shaft, a connecting ring, and a gasket. This device uses the flow of cooling water to drive the ribbon to rotate automatically in the heat exchange tube. The running spiral ribbon changes the running state of the water in the tube and expands the turbulent flow area. However, the simple use method of the thread can no longer meet the requirements of high-efficiency heat transfer, and the structure of the copper tube will be softened to a certain extent after being heated and is prone to deformation under pressure. In view of this, a lightweight closely-toothed internal-thread copper tube is proposed. Content of the Utility Model

The heat dissipation and cooling mechanism includes a second connecting pipe, a rubber sealing ring, a filling groove, a sealing block, a plurality of heat dissipation fins, a threaded copper pipe inner lining pipe, and a mesh thread.

[0010] Preferably, the rubber sealing ring is fixedly installed on the outer surface of the first connecting pipe, and the filling groove is opened on the outer surface of the rubber sealing ring.

[0017] 1. For this lightweight inner threaded copper pipe with dense teeth, it is connected through the threads inside the first connecting pipe and the second connecting pipe. When connecting, the sealing block fixedly installed on the inner surface of the second connecting pipe is filled into the filling groove in the rubber sealing ring fixedly installed on the outer surface of the first connecting pipe for sealing treatment. In this way, the rubber sealing ring can completely wrap both sides of the sealing block for double-layer sealing, further improving the sealing effect and reducing the occurrence of liquid leakage.

[0018] 2.

[0019] 3. For this lightweight inner threaded copper pipe with dense teeth, compared with the traditional way of using a vertical inner surface for conveying, the present utility model adopts a grid-like structure formed by the interlacing of spiral tooth grooves with different directions, effectively increasing the heat dissipation area per unit length of the copper pipe, strengthening the evaporation of the refrigerant, improving the heat exchange efficiency of the air-conditioning pipe, and being more convenient and practical.
