Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioning units, specifically relating to a liquid receiver fixing structure for a V-type integrated refrigerant pump condenser. Background Technology

[0002] In traditional data center air conditioning outdoor unit technology, the system primarily relies on the condenser to directly condense gaseous refrigerant into liquid, which is then directly delivered to the throttling device and evaporator. However, in data center environments with complex operating conditions and significant load fluctuations, the load can change with equipment operation, leading to an imbalance in cooling capacity supply and poor cooling performance. Simultaneously, excessive accumulation of liquid refrigerant in the condenser can affect heat transfer efficiency and reduce overall system energy efficiency. Furthermore, poor gas-liquid separation can cause gaseous and liquid refrigerant to mix and enter the throttling device, potentially leading to throttling abnormalities and damaging critical components.

[0003] The aforementioned problems can be solved by adding a liquid receiver. When the outdoor unit is equipped with a liquid receiver, it can flexibly respond to dynamic changes in the computer room load. When changes in the utilization rate of computer room equipment cause load fluctuations, the liquid receiver can store or release refrigerant to maintain a reasonable refrigerant circulation volume within the system. Without a liquid receiver, the system struggles to adapt well to such changes, easily leading to insufficient or excessive cooling. Secondly, the liquid receiver effectively improves the working condition of the condenser, preventing excessive accumulation of liquid refrigerant in the condenser and ensuring that the condenser always operates with high heat transfer efficiency, thus improving the overall energy efficiency of the refrigeration system. In contrast, the performance of the condenser in an outdoor unit without a liquid receiver is significantly affected under high or low load conditions. Furthermore, the liquid receiver enables gas-liquid separation, ensuring that only pure liquid refrigerant enters the expansion valve, guaranteeing stable throttling effects, reducing the risk of damage to critical system components, and mitigating problems such as abnormal throttling and component damage that may occur when gas and liquid mix into the throttling device in a system without a liquid receiver.

[0004] However, the outdoor units of air conditioners used in China's domestic computer rooms are usually not equipped with liquid receivers, and the condensers are V-shaped. After introducing liquid receivers, it is also necessary to solve the installation and fixing problem between them and the V-shaped integrated refrigerant pump condensers. Summary of the Invention

[0005] To solve the installation and fixing problem between the liquid receiver and the V-type integrated fluorine pump condenser, this utility model provides a liquid receiver fixing structure for the V-type integrated fluorine pump condenser.

[0006] The liquid receiver fixing structure of the V-type integrated fluorine pump condenser of this utility model includes a liquid receiver and two support plates. Two fins are fixed on the outer wall of the liquid receiver. The middle part of the two support plates and the two fins are fixedly connected. The upper end of each support plate is a wedge for fitting and mounting on the top plate of the fan and the top plate of the heat exchanger. The lower end of each support plate has a horizontal surface for fitting and mounting on the base.

[0007] Furthermore, the fins are provided with several through holes, and the support plate is provided with screw holes in the middle that correspond to the through holes on the fins. Screws are used to fasten the fins and the support plate together.

[0008] Furthermore, the wedge of the support plate has mounting holes, and a first mounting plate is fixed on each of the two sides of the wedge. The first mounting plate is parallel to the wedge surface and also has mounting holes.

[0009] Furthermore, the lower end of the support plate is provided with mounting holes, and a horizontal second mounting plate is fixed on each of the two sides of the lower end of the support plate. The second mounting plate is also provided with mounting holes.

[0010] Beneficial effects: By fixing the liquid receiver in the middle of the two support plates, this utility model can hang the liquid receiver at the highest possible position between the support plates and the V-type integrated fluorine pump condenser, ensuring that the liquid in the liquid receiver can flow downward by gravity. Moreover, the wedge at the upper end of the support plate can stably fit and fix the liquid receiver to the top plate of the fan and the top plate of the heat exchanger in the V-type condenser. The lower end has a horizontal surface suitable for stably fitting and fixing to a flat base. By setting fins on the liquid receiver and threading them to the support plate, installation and disassembly are convenient. By opening mounting holes and setting a first mounting plate at the upper end of the support plate, the installation is ensured to be firm. By setting mounting holes and a second mounting plate at the lower end of the support plate, the installation is ensured to be firm. Attached Figure Description

Detailed Implementation

[0012] 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.

[0013] like Figure 1-2As shown, a liquid receiver fixing structure for a V-type integrated fluorine pump condenser includes a liquid receiver 1 and two support plates 2. Two fins 11 are welded along the length of the outer wall of the liquid receiver 1. The two fins 11 are at the same height from the ground and correspond to each other. Each fin 11 has three through holes. Each support plate 2 has a screw hole in the middle that corresponds to the through hole on the fin 11. Screws are passed through the through holes of the fin 11 and screwed into the screw holes of the support plate 2 for fastening. The upper end of each support plate 2 has a wedge 21 for fitting and mounting on the top plate of the fan and the top plate of the heat exchanger. The lower end of each support plate 2 has a horizontal surface for fitting and mounting on the base.

[0014] The wedge 21 of the support plate 2 has mounting holes, and a first mounting piece 22 is fixed on each of the two sides of the wedge 21. The first mounting piece 22 is parallel to the inclined surface on the wedge 21, and also has mounting holes. Specifically, the support plate 2 is a U-shaped sheet metal part (i.e., it has a base plate and two side plates). The upper end of the base plate extends beyond the upper end of the side plates as the upper extension end, and the lower end of the base plate extends beyond the lower end of the side plates as the lower extension end (i.e., the length of the base plate is greater than the length of the side plates). The mounting holes on the wedge 21 are located on the upper extension end.

[0015] The lower end of the support plate 2 is provided with a mounting hole located on the lower protruding end. A horizontal second mounting piece 23 is fixed on each of the two sides of the lower end of the support plate 2. The lower side of the second mounting piece 23 is flush with the horizontal surface of the lower end of the support plate 2, and a mounting hole is also provided on the second mounting piece 23.

[0016] During actual installation, fixing holes are pre-drilled on the top plate of the fan, the top plate of the heat exchanger, and the base. Then, blind rivets are used to pass through the mounting holes at the upper end of the support plate 2 and nail them into the fixing holes on the top plate of the fan and the top plate of the heat exchanger for connection and fixation. Blind rivets are also used to pass through the mounting holes at the lower end of the support plate 2 and nail them into the fixing holes on the base for connection and fixation.

[0017] The aforementioned liquid reservoir 1 can be installed on a single-system outdoor unit, or two liquid reservoirs 1 can be installed on a dual-system outdoor unit.

[0018] Unless otherwise specified, all technologies mentioned above refer to existing technologies.

[0019] 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.
