DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] The embodiments of the present invention are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present invention.

[0044] The heat dissipation method of existing immersion liquid-cooled servers during production-side testing requires the cooperation of corresponding drying equipment, hoisting equipment, exhaust equipment, connecting pipes, etc. The entire system structure is complex, the cost is high, and it occupies a large space. In addition, the cost of liquid cooling fluid is high, and a single liquid cooling fluid cannot meet different needs. In order to solve the above problems, an embodiment of the present invention provides an auxiliary heat dissipation device and system. The above-mentioned auxiliary heat dissipation device and system are described in detail below.

[0045] First, refer to Figure 1 The auxiliary heat dissipation device 1 provided in the embodiment of the present invention includes: a fan module 101, including at least one heat dissipation fan 1011; an air suction cover 102, which is detachably installed on the air suction side of the fan module 101, and the air suction cover 102 has relatively arranged ventilation ports and air suction cover openings 1021, the ventilation ports face the fan module, and the air suction cover openings 1021 are used for electronic equipment to be cooled to extend therein; a power supply control module 103, which is electrically connected to the at least one heat dissipation fan 1011 and is used for powering and speed regulation of the at least one heat dissipation fan 1011.

[0046] The electronic device to be cooled may be a server, and the server may be an immersion liquid cooling server. The auxiliary heat dissipation device 1 is specifically used for cooling the immersion liquid cooling server during production end testing. The auxiliary heat dissipation device 1 uses air instead of liquid to achieve heat dissipation of the immersion liquid cooling server during production end testing, so that the immersion liquid cooling server can be tested in an air cooling environment.

[0047] The number of cooling fans 1011 in the fan module 101 can be set according to actual needs, for example, three, four, five, six, etc. When the number of cooling fans 1011 in the fan module 101 is multiple, the multiple cooling fans 1011 are arranged along the first direction. The first direction is specifically the length direction of the auxiliary cooling device 1. The first direction can refer to Figure 1 The direction indicated by the arrow A in the figure. When the cooling fan 1011 rotates, airflow can be generated. The cooling fan 1011 can be an axial flow fan. When the axial flow fan rotates, the airflow direction generated is parallel to the axis direction of the axial flow fan, which can generate a strong suction force. The cooling fan 1011 is preferably a dual-rotor axial flow fan.

[0048] The air suction side of the fan module 101 is located on one side of the fan module 101 along the third direction. The third direction is specifically the width direction of the auxiliary heat dissipation device 1. The third direction can be referred to as Figure 1 The direction indicated by the arrow C in the figure. The air suction cover 102 can be detachably mounted on the air suction side of the fan module 101, which is convenient for replacing the air suction cover 102. By replacing the air suction cover 102, the heat dissipation of various models of immersion liquid cooling servers can be compatible.

When the number of cooling fans 1011 in the fan module 101 is five, the power supply control module 103 can supply power to five cooling fans 1011 simultaneously through one power supply. For different cooling requirements of different electronic devices, the speed of the cooling fan 1011 can be adjusted by the power supply control module 103. For the heat dissipation of the same electronic device under different temperature conditions, the speed of the cooling fan 1011 can be adjusted by the power supply control module 103 to ensure that the electronic device can achieve better heat dissipation effect under different temperature conditions.

In this embodiment, there are several auxiliary heat dissipation devices 1, and several auxiliary heat dissipation devices 1 can be placed on a server support frame, and the server support frame has several server placement positions for placing servers. The air suction hood opening 1021 of the air suction hood 102 faces the server placement position. When the server is placed, first put the server into the server placement position, and then push the server toward the auxiliary heat dissipation device 1 until the server is pushed into the air suction hood 102.

[0077] The speed control instruction sent by the host computer 5 may include a speed coefficient, wherein the larger the speed coefficient is, the larger the speed of the cooling fan 1011 to be controlled is. The speed coefficient may range from 0 to 255, and at this time, the cooling fan 1011 may be adjusted in 256 speeds. When the speed coefficient is 0, it indicates that the speed of the cooling fan 1011 is the lowest, and when the speed coefficient is 255, it indicates that the speed of the cooling fan 1011 is the highest.

[0078] The speed control signal output by the control device 4 to the power supply control module 103 includes the above-mentioned pulse width modulation signal. The single-chip microcomputer can be wirelessly connected to the host computer 5 through the factory's wireless network. When the single-chip microcomputer is wirelessly connected to the host computer 5, the single-chip microcomputer uses the last five bits of its own MAC (Media Access Control) address as a unique identifier. After the single-chip microcomputer is successfully connected to the host computer 5, the online registration method can be executed first. When executing the online registration method, the MAC address of the single-chip microcomputer can be written into the industrial computer database through the host computer 5, indicating that the pulse width modulation module corresponding to the single-chip microcomputer has been online and can be controlled.

[0079] The industrial computer 6 can be wirelessly connected to the host computer 5 through the factory's wireless network.

The 54V DC output by the DC power supply module 201 may be divided into multiple paths to supply multiple fan modules 101. For example, when the number of fan modules 101 is 13 and the number of power supply control modules 103 is 13, the 54V DC output by the DC power supply module 201 is divided into 13 paths, and each path of 54V DC is connected to the fan module 101 through the second fuse 8, the relay 3011, and the power supply control module 103.

[0085] Among them, one output port corresponds to a power supply control module 103 in an auxiliary heat dissipation device 1, and one relay corresponds to a power supply control module 103 in an auxiliary heat dissipation device 1. The device identification information of the electronic device to be cooled can be the identification code of the electronic device, and the position identification information of the placement position can be the position number corresponding to the placement position, for example, K13-N01-A01.

The module identification information of the relay module 301 can be the IP address of the relay module 301, and the relay identification information can be the port number of a separate relay in the relay module 301. After the corresponding device identification information, position identification information, module identification information and output port identification information, module identification information and relay identification information are bound, they will be uploaded to the database for storage. It should be noted that the binding operation will only be performed when it is used for the first time or there is a change.
