detailed description

The utility model will be further described below in conjunction with the accompanying drawings and examples. The implementation of the utility model includes but not limited to the following examples.

Example

As shown in Figures 1 and 2, a built-in energy-saving air conditioner integrated with a cabinet includes an air conditioner housing 10, and a surface cooler 2 arranged in the air conditioner housing; the surface cooler separates the inside of the air conditioner housing into Two cavities, one of which is the return air duct 1, and the other cavity is the air supply duct 4; the air-conditioning housing is provided with a return air outlet 5 communicating with the return air duct, and is also provided with a The air supply port 6 connected to the air supply duct; the inside of the air conditioner casing is also provided with a fan 3 located in the air supply duct.

In actual use, the utility model is embedded in the cabinet, specifically, the utility model can be installed in the lower part of the cabinet, and the server is located at the top of the utility model, and the cabinet is divided into hot aisle 7 and cold aisle 8. The utility model is extremely convenient to be installed in the cabinet, greatly reduces the difficulty of installation and reduces the cost. Simultaneously, because the server is located at the top of the utility model, the distance is very close, when the server is cooled, the cold air flow is directly sent to the air inlet of the server through the air supply port, so that the short-distance air supply can greatly improve the cooling efficiency.

Specifically, the surface cooler is arranged obliquely in the air conditioner housing. This setting can better play a role in heat exchange, and better cool down the hot air flow, so as to cool down the server.

Specifically, the fan is an EC fan with stepless speed regulation. It intelligently matches the power of the fan according to the actual operating load of the server, changes the wind speed, and provides sufficient air circulation power to effectively reduce the energy consumption of the data center.

Specifically, the air return port and the air supply port are arranged on the top of the air conditioner casing. Setting the air return port and the air supply port at the top can reduce the connection distance with the cold aisle and the hot aisle, so that the hot air can quickly enter the air conditioner shell for heat exchange, and at the same time, the cold air can quickly enter the cabinet to cool down the server , greatly improving the cooling efficiency.

It is worth noting that the air conditioner casing of the present utility model is also connected to the outdoor unit by a liquid inlet pipe and an exhaust pipe, and the outdoor unit includes a compressor, a condenser, a condensing fan, and electrical control components, etc. body, surface cooler, etc. to form a complete refrigeration system. The above-mentioned liquid inlet pipe, exhaust pipe, outdoor unit, compressor, etc. are prior art, and their connection methods are also existing methods, so they will not be repeated here.

As shown in Figure 3,

After the utility model is installed in the cabinet, the working process of the utility model is as follows: After the whole cabinet is supplied with power, turn on the equipment such as the server and the utility model. After starting to work normally, the server emits a large amount of heat, which is taken out by the server. At the same time, under the action of the fan, the air circulates continuously, and the heat reaches the air return port on the air conditioner shell along the hot channel, and enters the return air channel in the air conditioner shell. , After cooling the air by the surface cooler, it is sent out from the air supply port and enters the cold aisle. At this point, the cold energy is delivered to the server, and the hot spot is directly cooled.

During the actual operation of the computer room, the server load is in a state of constant change. When the load is full, the air conditioner runs at full speed; when the load decreases, the fan automatically adjusts the speed and runs at a reduced speed. It not only fully guarantees the actual cooling demand, but also makes the operation of the air conditioner more intelligent, more efficient and energy-saving.

It is worth noting that the cabinet involved in the utility model can be added as a module, which makes the expansion of the computer room more convenient, flexible and maneuverable, and solves the problem of difficult and long-term renovation of the existing computer room.

According to above-mentioned embodiment, just can realize the utility model well. It is worth noting that, based on the premise of the above-mentioned structural design, in order to solve the same technical problem, even if some insubstantial changes or embellishments are made on the utility model, the essence of the technical solution adopted is still the same as that of the utility model. same, so it should also be within the protection scope of the present utility model.
