detailed description

The present application will be further described in detail below with reference to the accompanying drawings and embodiments. Understand The specific embodiments described herein are merely illustrative of the invention, rather than the invention. It is also to be noted that, for the convenience of description, only the parts related to the related invention are shown in the drawings.

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1. FIG. 1 shows an exemplary structural diagram of a cooling device of a data center cabinet according to an embodiment of the present application.

As shown in FIG. 1, the cooling device of the data center cabinet may include, but is not limited to, a heat exchange coil, a liquid supply pipe, a liquid return pipe, a cooler fan, and a fan control panel.

The heat exchange coil 110 is disposed on the air outlet side of the cabinet.

The heat exchange coil is a coiled pipe unit with good thermal conductivity. The pipe wall acts as a heat transfer medium, which can transfer the heat in the air outside the pipe to the coolant in the pipe, thereby absorbing the hot air outside the cooling pipe. The heat is used to cool the air.

The arrangement of the heat exchange coils may be determined based on the arrangement of the heat dissipation sources in the cabinets or the cabinet columns formed by the cabinets, the heat dissipation power, and the cooling power of the heat exchange coils. For example, when the cooling coil of the heat exchange coil has a large cooling power and can meet the heat dissipation power of all the heat dissipation sources in one cabinet or multiple cabinets, one heat exchange coil can be set for one cabinet or multiple cabinets; When the cooling power is small and the heat dissipation power of each heat source in the cabinet is high, the heat exchange coils can be set for the heat dissipation source (such as the server) in the cabinet.

The liquid supply pipe 120, the output port of the communication cooler and the input port of the heat exchange coil, are used for transmitting the coolant outputted by the cooler to the heat exchange coil; the liquid return pipe 130, the output port of the heat exchange coil and the outlet The input port of the cooler is used to return the coolant output from the heat exchange coil to the cooler.

In the present application, the communication mode between the heat exchange coil and the liquid supply pipe and the liquid return pipe may be various communication modes in the existing or future development technologies, which is not limited in the present application. For example, the liquid supply pipe and the liquid return pipe can be set at any position according to the user's production requirements; the connection between the heat exchange coil and the liquid supply pipe and the liquid return pipe can be an active connection for plugging and unloading and maintenance. The liquid supply pipe here refers to the pipe of the output port of the communication cooler and the input port of the heat exchange coil. The return pipe refers to the pipe of the output port of the heat exchange coil of the joint and the input port of the cooler.

The cooler 140 cools the coolant returned from the return pipe and outputs it to the liquid supply pipe. Any of the prior art or future developed cooling devices, for example, the cooler may be a heat sink that transfers heat generated by the machine or other appliance during operation to avoid affecting its normal operation, alternatively In addition, the cooler may also be a heat exchanger or the like of a device that transfers a part of the heat of the hot fluid to the cooling medium, which is not limited in the present application.

The cooling liquid is a liquid cooling medium that continuously circulates in the cooling device to achieve refrigeration, such as cooling oil or cooling water. The coolant can absorb the heat of the hot air in the heat exchange coil 110, and transfer heat to the surrounding cooling medium in the cooler to achieve its own cooling.

The fan 150 may be disposed on the air outlet side of the heat exchange coil for extracting air to form an air flow. The fan control board 160 can be disposed along the airflow direction for controlling the fan action to form an air flow.

An air flow cavity may be left between the heat exchange coil and the server node in the cabinet, between the heat exchange coil and the heat dissipation fan, so that the air flows, thereby improving the cooling efficiency.

In some optional implementations, a portion of the liquid supply pipe is connected to another portion of the liquid supply pipe with an interface and a valve; and a portion of the liquid return pipe is connected to another portion of the liquid return pipe with an interface and a valve.

In some optional implementations, the water inlet of the heat exchange coil is in communication with a portion of the liquid supply tube through the quick joint; and the water outlet of the heat exchange coil is in communication with a portion of the liquid return tube through the quick joint.

In some optional implementations, the water inlet of the heat exchange coil is in communication with a portion of the liquid supply tube through the hose; and the water outlet of the heat exchange coil is in communication with a portion of the liquid return tube through the hose.

In some alternative implementations, a flow distributor for powering the delivery of the coolant may be provided in the liquid supply tube.

In some optional implementations, the cooler may include: a heat exchanger for communicating the liquid supply tube to output the cooling liquid, communicating the liquid return pipe to input the cooling liquid; and for providing the cooling medium in the cooling heat exchanger One or both of the refrigerator and cooling tower of the coolant.

The above embodiment of the present application cools the air on the air outlet side of the cabinet, so that the cooled air can enter the air inlet side of the cabinet, shortening the circulation path of the cooling air, thereby improving the heat dissipation efficiency of the cabinet and the equipment room.
