Description

Technical Field

[0001] The utility model relates to the technical field of computer servers. More specifically, the utility model relates to a 1U server liquid cooling module. Background Art

[0002] With the rapid development of artificial intelligence, as the core device of computing power, the power of servers is constantly increasing. In order to improve server performance and strengthen the requirements for green development of data centers, efficient thermal management technology has become crucial. Due to its unique application scenarios, in-vehicle servers face challenges such as limited space inside the vehicle and poor air circulation. Traditional air-cooling methods are difficult to meet the heat dissipation requirements of high-power server devices. In addition, problems such as noise generated by fan operation and easy dust contamination of devices also affect the quietness of the in-vehicle environment and the long-term stable operation of devices.

[0003] To overcome the above technical problems, this solution designs a server module with both liquid-cooling and air-cooling dual heat dissipation systems. This module uses efficient liquid cooling for core heat-generating components such as server motherboards, power modules, and hard disks, and uses fans for auxiliary heat dissipation of secondary heat-generating components such as memory modules to ensure stable operation of the device even in high-temperature environments. In addition, this module also integrates optoelectronic signal connectors to achieve seamless transmission of optical and electrical signals, meeting the requirements of in-vehicle communication systems for high-speed and stable data transmission, and providing a reliable heat dissipation and signal transmission solution for in-vehicle communication devices. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a 1U server liquid cooling module, which can provide safe and stable support for motherboards, power supplies, hard disks, etc., and at the same time can provide efficient cooling effects.

[0005] The technical solution adopted by the utility model to solve this technical problem is: a 1U server liquid cooling module, including: a housing, a server motherboard, a power module, a hard disk box, a liquid cooling cold plate, a water inlet joint, a water outlet joint, an LRM connector, and a guide pin;

[0006] The two sides of the housing are provided with guide rails. The server motherboard, power module, hard disk box, and liquid cooling cold plate are all installed in the housing. The server motherboard is fixed between the liquid cooling cold plate and the bottom panel of the housing. One end of the liquid cooling cold plate is installed with an LRM connector, a water inlet joint, a water outlet joint, and a guide pin. The guide pin is on the same side as the LRM connector, the water inlet joint, and the water outlet joint. Loose-proof screws and extractors are installed at both ends of the front panel of the housing close to the guide rails.

[0007] As a further solution of the utility model: indicator lights, switches, and USB interfaces are installed on the front panel of the housing.

[0008] As a further solution of the present utility model: ventilation holes are formed in the front and rear panels of the housing to form an air duct, a wire mesh is installed on the rear panel of the housing, and a fan is installed on the front panel of the housing.

[0009] As a further solution of the present utility model: the optical interfaces in the LRM connector are arranged in a dislocation manner with the optical interfaces in the server main board.

[0010] As a further solution of the present utility model: the CPU and the two-bridge heat-generating components on the server main board are attached to the corresponding heat dissipation bosses of the liquid cooling cold plate through heat-conducting rubber pads.

[0011] As a further solution of the present utility model: the bottom inside the housing has screw mounting holes and bosses.

[0012] As a further solution of the present utility model: a flow channel is arranged inside the liquid cooling cold plate, the water inlet of the flow channel is connected to a water inlet joint, and the water outlet of the flow channel is connected to a water outlet joint.

[0013] The present utility model has at least the following beneficial effects: the 1U server liquid cooling module provides installation support for the server main board, power module, hard disk box, and other accessories such as guide pins and fluid connectors. The main board is fixed to the cold plate and installed inside the housing. The LRM connector and the fluid connector (quick blind plug water joint) are installed at one end of the cold plate. In addition, there is a flow channel inside the liquid cooling cold plate. The fluid enters through the water inlet joint at one end of the flow channel, circulates inside the flow channel, and then flows out from the water outlet joint at the other end of the flow channel. In this way, the heat dissipated by the electronic components on the surface of the main board is taken away through repeated circulation, so as to achieve the effect of efficient cooling.

[0014] Guide rails are designed on both sides of the module. A puller and non-loosening screws are installed on the front panel of the module. The module is inserted and installed with an external chassis or a rack through the guide rails, and accurate positioning is achieved by the guide pins on the rear panel to ensure that the fluid connector plug and the LRM connector are accurately inserted into the corresponding sockets. After the insertion is in place, the front panel puller is used to achieve quick locking, and the non-loosening screws are used to achieve reinforcement locking.
