Abstract

The utility model discloses a bottom-mounted multi-connection heat pipe cooling system of a micro-channel heat exchanger, which comprises a cabinet, a cold air channel, a centrifugal fan, a micro-channel heat exchanger and an overhead layer. It is an open type, and there is a cold air channel between each two cabinets. A centrifugal fan is installed under the cold air channel. The centrifugal fan blows cold air into the cold air channel through an electric air valve, and the centrifugal fan is installed in the overhead layer. The centrifugal fan is also connected with a micro-channel heat exchanger. The utility model is different from the traditional cold channel closed heat dissipation, and is convenient and practical. The bottom of the microchannel heat exchanger is placed for centralized heat exchange, which is more concentrated and efficient than the heat exchange method of each cabinet backplane. Moreover, the centrifugal The fan heat exchange, the heat exchange speed is faster, and the dust in the computer room is filtered through the filter, so that the cabinets in the computer room absorb less dust and prolong their service life.

Description

Bottom-mounted multi-connected heat pipe cooling system with micro-channel heat exchanger

technical field

The utility model relates to the technical field of cooling of a communication machine room, in particular to a multi-connected heat pipe cooling system with a bottom-mounted microchannel heat exchanger.

Background technique

The problem of heat dissipation and power consumption in the computer room has always been an important factor that needs to be considered in the communication computer room. The traditional precision air conditioner has always restricted the development of the communication computer room due to the problem of power consumption. Recently, a new type of water-cooled backplane has also appeared in China, but there are always potential safety hazards in the operation of the computer room in a water environment, and the contact area between the hot air and the backplane of the traditional backplane heat dissipation structure is too small, the utilization rate is not high, and the heat dissipation effect is not good. obvious.

Utility model content

The purpose of the utility model is to provide a multi-connected heat pipe cooling system with a bottom-mounted microchannel heat exchanger to solve the problem of low heat exchange efficiency in the actual application of the existing multi-connected heat pipe cooling system in a backplane type communication room.

The utility model is achieved through the following technical solutions:

Micro-channel heat exchanger bottom-mounted multi-connected heat pipe cooling system, including cabinets, cold air channels, centrifugal fans, micro-channel heat exchangers and overhead floors. An overhead layer is provided under the cabinet, and the end of the overhead layer is open. Each There is a cold air channel between the two cabinets, and a centrifugal fan is arranged below the cold air channel. The centrifugal fan blows cold air into the cold air channel through the electric air valve, and the centrifugal fan is installed in the overhead layer. A microchannel heat exchanger is attached.

Preferably, the air outlet of the centrifugal fan is provided with a filter.

Preferably, the micro-channel heat exchanger is arranged at a position where the overhead floor communicates with the cabinet.

In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

The utility model is different from the traditional cold channel closed heat dissipation, convenient and practical, and the bottom of the microchannel heat exchanger is placed for centralized heat exchange, which is more concentrated and efficient than the method of heat exchange on the back plate of each cabinet, and, moreover, The centrifugal fan is used for heat exchange, and the heat exchange speed is faster, and the dust in the machine room is filtered through the filter, so that the cabinets in the machine room absorb less dust and prolong their service life.

Description of drawings

The utility model will be explained by way of example and with reference to the accompanying drawings, wherein:

Fig. 1 is the structural representation of the utility model;

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figure 1, the microchannel heat exchanger bottom-mounted multi-connected heat pipe cooling system includes a cabinet 1, a cold air channel 2, an AC centrifugal fan 5, a microchannel heat exchanger 3, and an overhead floor 7. The overhead layer 7, the end of the overhead layer 7 is open, there is a cold air passage 2 between each two cabinets 1, and an AC centrifugal fan 5 is arranged below the cold air passage 2, and the AC centrifugal fan 5 passes through the electric air valve 4 Blow cold air into the cold air channel 2, and the AC centrifugal fan 5 is installed in the overhead layer 7, and the AC centrifugal fan 5 is also connected with a micro-channel heat exchanger 3, and the micro-channel heat exchanger 3 is arranged on the overhead layer 7 At the position communicating with the cabinet 1, the air outlet of the AC centrifugal fan 5 is provided with a filter 6.

Concrete implementation method of the present utility model:

The heat in the communication cabinet enters the micro-channel heat exchanger placed at both ends of the overhead floor through the two ends of the overhead floor. After the micro-channel heat exchanger has undergone sufficient heat exchange, the AC fan blows the cold air after heat exchange through the cold air channel. In the engine room. Compared with the method of exchanging heat on the back panel of each cabinet, this heat exchange method is more concentrated and more efficient, and the centrifugal fan filters the dust in the machine room through the filter.

The specific embodiments described above have further described the purpose, technical solutions and beneficial effects of the present utility model in detail. It should be understood that the above descriptions are only specific embodiments of the present utility model and are not intended to limit the present invention. utility model.
