Technical Field

[0001] This utility model belongs to the technical field of ceiling-mounted air conditioning units, specifically relating to a ceiling-mounted air conditioner that uses gravity heat pipes. Background Technology

[0002] In the current booming digital economy, data centers, as the core carriers of digital infrastructure, are increasingly attracting widespread attention due to their energy consumption issues. Statistics show that air conditioning systems in traditional data centers account for 40%-50% of energy consumption, far exceeding the energy consumption of servers and other IT equipment. This phenomenon has become a key bottleneck restricting the sustainable development of the industry. Especially under the "dual-carbon" strategic goal, improving the energy efficiency of air conditioning systems through technological innovation is not only related to controlling operating costs for enterprises, but also an inevitable requirement for fulfilling social responsibility and promoting green development. Currently, optimizing the energy efficiency of air conditioning systems has become a top priority in data center energy conservation and emission reduction efforts, urgently requiring breakthrough solutions from multiple dimensions such as equipment selection, system design, and operation and maintenance.

[0003] Currently, ceiling-mounted air conditioning units have become a common cooling solution for data centers and communication equipment rooms due to their unique installation method. They are ceiling-mounted, saving floor space and are particularly suitable for server rooms with limited area and requiring high-density equipment layouts. However, because they need to be installed above server racks, maintenance and operation of ceiling-mounted air conditioning units require working at height, increasing maintenance costs.

[0004] Currently, ceiling-mounted air conditioners often use multi-split systems, which have relatively low overall heat exchange efficiency, especially when the terminal unit is running at low load. Summary of the Invention

[0005] To address the issues of high maintenance costs and low overall heat exchange efficiency associated with ceiling-mounted air conditioners, which require working at heights for maintenance and operation, this invention provides a ceiling-mounted air conditioner.

[0006] The ceiling-mounted air conditioner of this utility model includes a housing, an electrical box, an air conditioning system main control board, a fan, an inlet pipe, an outlet pipe, an air filter and a heat exchanger installed inside the housing, and a maintenance and inspection door installed on the housing. A fan mounting port is provided at the bottom of the housing, and the fan is installed in the fan mounting port. One end of the outlet pipe is located inside the housing and communicates with the outlet of the heat exchanger, while the other end extends out of the housing. One end of the inlet pipe is located inside the housing and communicates with the inlet of the heat exchanger, while the other end extends out of the housing. The electrical box is an external type and is used to install it in the ground control area of ​​the machine room. The air conditioning system main control board is located inside the electrical box and is connected to the fan inside the housing through wires. A mounting bracket is provided on the housing for installing the air conditioner on the indoor ceiling.

[0007] Furthermore, the liquid inlet pipe extends out of the housing through the liquid inlet port, and the vent pipe extends out of the housing through the vent port. Both the liquid inlet port and the vent port are located on the side wall of the housing.

[0008] Furthermore, the mounting bracket includes mounting plates, lead screws, and nuts. There are several mounting plates, symmetrically distributed on the outer side walls of two opposing side plates of the housing. The mounting plates have through holes, and the lead screws pass vertically through the through holes. Each lead screw is threaded with two nuts.

[0009] Furthermore, each side plate has six mounting pieces arranged in three pairs, three on top and three on the bottom, and six lead screws, with one lead screw for each pair of mounting pieces.

[0010] Beneficial effects: The ceiling-mounted air conditioner of this utility model has a compact and beautiful structure, flexible installation, and simple maintenance; ceiling installation saves floor space in the machine room; the electrical box is separated from the air conditioner and installed in the ground control area, making operation and maintenance convenient and reducing maintenance costs; the main control board of the air conditioning system is removed from the air conditioner and located in the electrical box, so that there are no components such as the main control board of the air conditioning system inside the casing that affect wind resistance, thereby reducing fan power and improving energy efficiency; by having the liquid inlet pipe and the air outlet pipe extend from the side wall, the required clearance height for the installation of the ceiling-mounted air conditioning unit is reduced; by having the mounting bracket include mounting plates, screws, and nuts, the structure is simple and easy to install; by setting the mounting plates in pairs and distributing them vertically, the air conditioner is ensured to be stable and not shake after installation.

[0014] 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.

[0015] like Figure 1-2As shown, a ceiling-mounted air conditioner includes a housing 1, an electrical box 2, an air conditioning system main control board (not shown), a fan 3, an inlet pipe 6, an outlet pipe 7, an air filter 4 and a heat exchanger 5 installed inside the housing 1, and a maintenance and inspection door 8 installed on the housing 1. The bottom of the housing 1 has a fan mounting port, and the fan 3 is installed in the fan mounting port. One end of the outlet pipe 7 is located inside the housing 1 and communicates with the outlet of the heat exchanger 5, while the other end extends out of the housing 1. One end of the inlet pipe 6 is located inside the housing 1 and communicates with the inlet of the heat exchanger 5, while the other end extends out of the housing 1. The electrical box 2 is an external type and is used to install in the ground control area of ​​the machine room. The air conditioning system main control board is located inside the electrical box 2 and is connected to the fan 3 inside the housing 1 through wires. The housing 1 is provided with a mounting bracket 9 for installing the air conditioner on the indoor ceiling.

[0016] Specifically, the liquid inlet pipe 6 extends out of the housing 1 through the liquid inlet port, and the air outlet pipe 7 extends out of the housing 1 through the air outlet port. Both the liquid inlet port and the air outlet port are located on the side wall of the housing 1. The mounting bracket 9 includes mounting plates 1, lead screws 92, and nuts 93. There are twelve mounting plates 1, symmetrically distributed on the outer side walls of two opposing side plates of the housing 1. Six mounting plates 1 are distributed on each side plate to form three pairs, three on top and three on the bottom. Each mounting plate 1 has a through hole. There are six lead screws 92. Each pair of mounting plates 1 is equipped with one lead screw 92. The lead screws 92 pass vertically through the through holes, and each lead screw 92 is threaded with two nuts 93.

[0017] During installation, first, a support frame is pre-installed on the indoor ceiling. The support frame has through holes corresponding to the six lead screws 92 for the lead screws 92 to pass through. Then, the six lead screws 92 are vertically passed through the six pairs of mounting plates 1 respectively. A nut 93 is screwed onto the lower end of each lead screw 92 for limiting. After the upper ends of the six lead screws 92 are passed through the through holes of the support frame, the nuts 93 are screwed onto the top of the lead screws 92 for tightening.

[0018] This invention features an external electrical box 2, allowing it to be installed in other locations within the data center server room, thus increasing the compatibility of the air conditioning unit. Simultaneously, the main control board of the air conditioning system is removed from the air conditioner and integrated into the electrical box 2, reducing the overall air resistance of the unit. This results in lower overall air resistance, lower fan power consumption for the same airflow, and higher energy efficiency. The heat exchanger 5 uses a microchannel heat exchanger, achieving better heat exchange efficiency while reducing its size. The fan 3 consists of two EC axial flow fans, characterized by long air delivery distance and low power consumption. Both the liquid inlet pipe 6 and the air outlet pipe 7 exit from the side wall, effectively reducing the required clearance height for ceiling-mounted air conditioning installation compared to traditional top-mounted pipes. Six threaded rods (92mm) are used for hoisting, ensuring the stable installation of the ceiling-mounted air conditioning unit.

[0019] Unless otherwise specified, all technologies mentioned above refer to existing technologies.

[0020] 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.
