Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically a condenser for a two-inlet, one-outlet ice cube machine. Background Technology

[0002] A condenser, a component of a refrigeration system, is a type of heat exchanger that converts gas or vapor into liquid, rapidly transferring heat from the pipes to the surrounding air. The condenser's operation is exothermic, hence its relatively high temperature. An ice cube machine is a type of ice maker that uses a condenser to cool water with a refrigerant in the refrigeration system, producing ice. Currently, most ice cube machines use a single-pipe condenser, and the heat exchange efficiency and effectiveness between the refrigerant and air still have room for improvement. Therefore, an improved technology is urgently needed to address this issue in existing technologies. Utility Model Content

[0003] The purpose of this invention is to provide a condenser for a two-inlet, one-outlet ice cube machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a condenser for a two-inlet, one-outlet type ice cube machine, comprising a shell, an inlet pipe, a first copper pipe, a second copper pipe, a third copper pipe, and a three-way copper pipe connector. An inlet pipe is provided on one side of the upper part of the shell. There are multiple first and second copper pipes, each located in the upper part of the shell. The first and second copper pipes are each situated on a vertical plane. One end of the top first and second copper pipes is connected to the inlet pipe. There are multiple third copper pipes, all located in the lower part of the shell. The first and second copper pipes are arranged alternately in the vertical direction. All first copper pipes are connected sequentially via first elbows, all second copper pipes are connected sequentially via second elbows, and all third copper pipes are connected sequentially via third elbows. The bottom first and second copper pipes are connected to the three-way copper pipe connector. The remaining port of the three-way copper pipe connector is connected to one end of the top third copper pipe. One end of the bottom third copper pipe extends out from the side of the shell to the outside of the shell.

[0005] Preferably, the present invention provides a condenser for a two-inlet, one-outlet type ice cube machine, wherein the shell is densely covered with fins, the fins are installed inside the shell by a bracket, and the first copper tube, the second copper tube and the third copper tube are all inserted through the fins.

[0006] Preferably, the condenser for a two-inlet, one-outlet ice machine provided by this utility model has a fan mounting hole on the front side of the housing.

Therefore, they should not be construed as limitations on this utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a condenser for a two-inlet, one-outlet type ice cube machine, including a shell 1, an inlet pipe 2, a first copper pipe 3, a second copper pipe 4, a third copper pipe 5, and a three-way copper pipe connector 6. The inlet pipe 2 is provided on one side of the upper part of the shell 1, and one side of the inlet pipe 2 is connected to the side wall of the shell 1 via a connecting rod 12 to achieve the installation of the inlet pipe 2. There are multiple first copper pipes 3 and second copper pipes 4, all located in the upper part of the shell 1, each on a vertical plane. One end of the first copper pipe 3 and the second copper pipe 4 at the top is connected to the inlet pipe 2. There are multiple third copper pipes 5, all located in the lower part of the shell 1. The first copper pipes 3 and second copper pipes 4 are arranged alternately in the vertical direction. All the first copper pipes 3 are connected sequentially via a first elbow 7, and all the second copper pipes 4 are connected via a second elbow. 8 are connected in sequence. All the third copper tubes 5 are connected in sequence through the third elbow 9. The first copper tube 3 and the second copper tube 4 at the bottom are connected to the three-way copper tube joint 6 respectively. The remaining interface of the three-way copper tube joint 6 is connected to one end of the third copper tube 5 at the top. One end of the third copper tube 5 at the bottom extends out from the side of the shell 1 to the outside of the shell 1. The shell 1 is densely covered with fins 10. The fins 10 are installed inside the shell 1 by the bracket. The first copper tube 3, the second copper tube 4 and the third copper tube 5 are all inserted through the fins 10. The fins 10 are set to ensure the heat exchange area of ​​the condenser. The front side of the shell 1 is provided with a fan mounting hole 11 for the installation of the fan assembly, thereby improving the heat exchange effect. The rear side of the shell 1 is an open structure to ensure that the air can pass through the shell 1 smoothly, thereby realizing heat exchange with the heat exchange medium of the first copper tube 3, the second copper tube 4 and the third copper tube 5.

[0019] Assembly method and operating principle: First, connect the first copper tube 3, the second copper tube 4, and the third copper tube 5 to the fins 10 respectively. Then, install the fins 10, which are connected to the first copper tube 3, the second copper tube 4, and the third copper tube 5, into the housing 1 using a bracket. The bracket is then fastened to the housing 1 with screws. Next, connect the topmost first copper tube 3 to the liquid inlet pipe 2, and extend one end of the bottommost third copper tube 5 to the outside of the housing 1. Connect the first copper tubes 3 sequentially by welding the first elbow 7 to form the first passage. Connect the second copper tubes 4 sequentially by welding the second elbow 8 to form the second passage. Connect the third copper tubes 5 sequentially by welding the third elbow 9 to form the third passage. Then, weld the ends of the first copper tube 3, the second copper tube 4, and the inlet end of the third copper tube 5 to the tee copper pipe connector 6 respectively, so that the first, second, and third passages are interconnected, completing the assembly. Before use, install the fan in the fan mounting hole 11 of the housing 1. In operation, the refrigerant enters the first copper pipe 3 and the second copper pipe 4 from the liquid inlet pipe 2, then exchanges heat with the water in the ice tray of the ice machine. It then converges into the third copper pipe 5 through the three-way copper pipe connector 6 and flows out of the condenser from the end of the third copper pipe 5. This invention has a reasonable structure, with the main pathway consisting of the first copper pipe 3, the second copper pipe 4, and the third copper pipe 5. The first copper pipe 3 and the second copper pipe 4 run parallel, and their ends are connected to the third copper pipe 5 through the three-way copper pipe connector 6. This two-way combined structure allows the refrigerant, initially in a high-pressure, high-temperature gaseous state, to flow downwards and be forced into a normal-temperature liquid state by a fan. The flow rate in the speed-limiting pipe forms a liquid storage function, ensuring the flow rate of the subsequent circulation and improving heat exchange efficiency. Furthermore, the staggered arrangement of the first copper pipe 3 and the second copper pipe 4 increases the heat exchange area of ​​the cross-section, thereby improving the heat exchange effect.
