Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioning units, specifically relating to a dual-coil parallel heat exchanger. Background Technology

[0002] In recent years, with the rapid development of the information technology industry, energy conservation and emission reduction in data centers has become a key performance indicator for various operating companies. The most important aspect of energy conservation and emission reduction in data centers is reducing the energy consumption of main communication equipment and air conditioning. Traditional data center air conditioning accounts for approximately 40% or even more of the electricity consumption, necessitating the rational configuration of air conditioning energy efficiency to save energy. This has become a key focus and direction of energy conservation and emission reduction efforts. Traditional single-coil, single-system heat exchanger air conditioners in data centers can no longer meet these requirements, demanding higher energy efficiency and higher heat exchange efficiency, thus requiring urgent solutions. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a dual-coil parallel heat exchanger.

[0004] The parallel dual-coil heat exchanger of this utility model includes two identical sets of dual-coil heat exchangers and four manifolds. The inlet pipe connected to the two distributors on the upper side of each set of dual-coil heat exchangers serves as the first inlet pipe, and the inlet pipe connected to the two distributors on the lower side serves as the second inlet pipe. The two outlet pipes on the inner side of each set of dual-coil heat exchangers serve as the first outlet pipe, and the two outlet pipes on the outer side serve as the second outlet pipe. The four manifolds are respectively the first inlet manifold, the second inlet manifold, the first outlet manifold, and the second outlet manifold, and are all located below the first inlet pipe, the second inlet pipe, the first outlet pipe, and the second outlet pipe. The first inlet pipe of both sets of dual-coil heat exchangers is connected to the first inlet manifold, the second inlet pipe is connected to the second inlet manifold, the first outlet pipe is connected to the first outlet manifold, and the second outlet pipe is connected to the second outlet manifold.

[0005] Furthermore, the first liquid inlet manifold, the second liquid inlet manifold, the first gas outlet manifold, and the second gas outlet manifold are all horizontally fixed by fasteners. This ensures that the liquid or gas flows smoothly within its respective pipe.

[0006] Furthermore, each fastener includes a support platform and a pair of cooperating clamping blocks, one of which is fixed to the support platform. Each clamping block has a semi-circular notch, and both ends of the first liquid inlet manifold, the second liquid inlet manifold, the first gas outlet manifold, and the second gas outlet manifold are fixed by the clamping of the clamping blocks. In this way, the structure is simple and the installation and fixing are convenient.

[0007] Furthermore, the heights of the first liquid inlet manifold, the second liquid inlet manifold, the first gas outlet manifold, and the second gas outlet manifold are all different. This facilitates the extension of the outlet section of each pipe.

[0008] Furthermore, the outlet sections of the first liquid inlet manifold, the second liquid inlet manifold, the first gas outlet manifold, and the second gas outlet manifold all extend towards the side away from the dual-coil heat exchanger. This facilitates connection to subsequent processing equipment.

[0009] Beneficial effects: The structure of this utility model of a parallel double-coil heat exchanger is compact and aesthetically pleasing, and easy to install; it has high heat exchange efficiency and significant energy-saving effect; by fixing each manifold horizontally, it ensures smooth flow of liquid or gas within its respective pipe; the structure of the fixing components is simple and easy to install and fix; by setting each manifold at a different height, it facilitates the extension of the outlet pipe section of each manifold; and by setting the outlet pipe sections of each manifold to a uniform orientation, it facilitates connection to subsequent processing devices.

Detailed Implementation

[0011] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0012] like Figure 1-2As shown, this utility model is a parallel dual-coil heat exchanger, including two identical sets of dual-coil heat exchangers 1 and four manifolds; the inlet pipe connected to the two distributors on the upper side of each set of dual-coil heat exchangers 1 serves as the first inlet pipe 11, and the inlet pipe connected to the two distributors on the lower side serves as the second inlet pipe 12; the two outlet pipes on the inner side of each set of dual-coil heat exchangers 1 serve as the first outlet pipe 13, and the two outlet pipes on the outer side serve as the second outlet pipe 14; the above four manifolds are respectively the first inlet pipes... The first liquid inlet pipe 2, the second liquid inlet pipe 3, the first gas outlet pipe 4, and the second gas outlet pipe 5 are all located below the first liquid inlet pipe 11, the second liquid inlet pipe 12, the first gas outlet pipe 13, and the second gas outlet pipe 14. The first liquid inlet pipe 11 of both sets of double-coil heat exchangers 1 is connected to the first liquid inlet pipe 2, the second liquid inlet pipe 12 is connected to the second liquid inlet pipe 3, the first gas outlet pipe 13 is connected to the first gas outlet pipe 4, and the second gas outlet pipe 14 is connected to the second gas outlet pipe 5.

[0013] Specifically, the first liquid inlet manifold 2, the second liquid inlet manifold 3, the first gas outlet manifold 4, and the second gas outlet manifold 5 are all horizontally fixed by fasteners 6. Each fastener 6 includes a support platform 61 and a pair of cooperating clamping blocks 62, one of which is fixed on the support platform 61. Each clamping block 62 has a semi-circular notch, and both ends of the first liquid inlet manifold 2, the second liquid inlet manifold 3, the first gas outlet manifold 4, and the second gas outlet manifold 5 are fixed by the clamping of the clamping blocks 62.

[0014] The heights of the first liquid inlet manifold 2, the second liquid inlet manifold 3, the first gas outlet manifold 4, and the second gas outlet manifold 5 are all different. The outlet pipe sections of the first liquid inlet manifold 2, the second liquid inlet manifold 3, the first gas outlet manifold 4, and the second gas outlet manifold 5 all extend towards the side away from the double-coil heat exchanger 1; for example, the outlet pipe sections of the first liquid inlet manifold 2 and the second liquid inlet manifold 3 are obtained by bending the outlet end at 90°, and the outlet pipe sections of the first gas outlet manifold 4 and the second gas outlet manifold 5 are all connected by a vertical pipe section in the middle of the first gas outlet manifold 4 and the second gas outlet manifold 5 as the outlet pipe section.

[0015] In actual installation, first, arrange the two identical sets of dual-coil heat exchangers 1 left and right. Then, install and fix four sets of support platforms 61 in pairs, with each set of support platforms 61 having a different height relative to the other sets. Install and fix (e.g., with screws) a clamping block 62 on each support platform 61. Then, place the first liquid inlet manifold 2, the second liquid inlet manifold 3, the first gas outlet manifold 4, and the second gas outlet manifold 5, which have already been set with their outlet pipe sections, into the recesses of the clamping blocks 62 on the four sets of support platforms 61. Then, clamp the remaining clamping blocks 62 onto each manifold and fix them (e.g., with screws), thereby fixing each manifold horizontally, ensuring that each manifold has a different height, and that each outlet pipe section faces the same direction. Of course, the number of each set of support platforms 61 can also be multiple.

[0016] Next, connect the lower end of the first liquid inlet pipe 11 of each dual-coil heat exchanger 1 to the lower first liquid inlet manifold 2, connect the lower end of the second liquid inlet pipe 12 to the lower second liquid inlet manifold 3, connect the lower end of the first gas outlet pipe 13 to the lower first gas outlet manifold 4, and connect the lower end of the second gas outlet pipe 14 to the lower second gas outlet manifold 5. At this point, the piping structure layout of the liquid inlet manifold and gas outlet manifold of the dual-coil parallel heat exchangers is complete.

[0017] Unless otherwise specified, all technologies mentioned above refer to existing technologies.

[0018] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification.
