Description

Technical Field

[0001] This utility model belongs to the field of liquid cooling plate technology, specifically relating to a novel direct-cooling liquid cooling plate. Background Technology

[0002] A liquid cooling plate, also known as a liquid heat exchanger, is a component used for heat dissipation in electronic devices. It absorbs and transfers heat through a liquid medium (usually water or antifreeze), effectively reducing the temperature of electronic components. Direct-cooling liquid cooling plates, also called direct liquid cooling plates, are a highly efficient heat dissipation solution primarily used in applications requiring high heat flux density, such as high-performance computing, data centers, and new energy vehicle power batteries. In direct-cooling liquid cooling plates, the coolant directly contacts the heat-generating components, absorbing heat through the flow of the liquid, thus achieving high heat dissipation efficiency.

[0003] Most existing liquid cooling plates are installed as a single structure at the bottom of electronic components, with only one unit operating. They cannot be individually adjusted according to the actual heat demand of different locations of heat-generating components, thus reducing heat dissipation efficiency. Furthermore, they lack self-cleaning functions, and prolonged use can easily cause microchannel blockage, affecting the service life of the liquid cooling plate. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new type of direct-cooling liquid cooling plate to solve the problems mentioned in the background art. Most of the existing liquid cooling plates are installed as a whole structure at the bottom of electronic components, with only one unit operating. They cannot be individually adjusted according to the actual heat demand of different positions of the heat-generating elements, thereby reducing heat dissipation efficiency. In addition, they do not have a self-cleaning function, and long-term use can easily cause microchannel blockage, affecting the service life of the liquid cooling plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel direct-cooling liquid-cooled plate, comprising a liquid-cooled plate body, a fixing plate fixedly connected inside the liquid-cooled plate body, a microchannel provided on one side of the fixing plate, a placement groove provided on one side of the liquid-cooled plate body, a connecting plate slidably connected inside the placement groove, a first slot provided inside each of the connecting plates, an installation groove provided on the other side of the liquid-cooled plate body, a second slot provided on one side of each installation groove, a moving plate slidably connected inside the installation groove, a diverter pipe fixedly connected to one end of the liquid-cooled plate body, a collector box fixedly connected to one end of the liquid-cooled plate body, and a leak detection sensor and an ultrasonic oscillator fixedly connected inside the liquid-cooled plate body respectively.

[0006] Preferably, each liquid cooling plate body has a positioning hole inside, and a fixing bolt is threaded into the positioning hole. The fixing bolt and the connecting plate are threaded together.

[0007] Preferably, each of the movable plates has a locking block fixedly connected to its top, and the locking block and the first locking slot are engaged, as are the locking block and the second locking slot.

[0008] Preferably, a sliding groove is provided on the other side of the mounting groove, and a limiting plate is fixedly connected to one side of the movable plate, with the limiting plate and the sliding groove being slidably connected.

[0009] Preferably, each of the diversion pipes has a conveying channel fixedly connected to its top.

[0010] Preferably, the diverter pipe is fixedly connected to the collector box via a connecting pipe.

[0011] Preferably, an inlet pipe is fixedly connected to one side of the diversion pipe, an outlet pipe is fixedly connected to one side of the collector box, a fixing block is fixedly connected to one side of the liquid cooling plate body, the fixing block and the inlet pipe are fixedly connected, the fixing block and the outlet pipe are fixedly connected, and an automatic valve is provided on the outside of both the inlet pipe and the outlet pipe.

[0012] Preferably, a temperature sensor is fixedly connected to one side of the collector box.

[0013] Compared with the prior art, this utility model provides a novel direct-cooling liquid cooling plate, which has the following beneficial effects:

[0014] 1. This utility model sets multiple liquid cooling plate bodies installed at the bottom of the heating element, allowing for individual operation of different heating positions. This can be adjusted according to the actual heat demand of the heating element, improving heat dissipation efficiency. Two liquid cooling plate bodies are connected by a connecting plate inserted into the mounting groove. Then, the moving plate is pressed upward to make it slide inside the mounting groove. The locking blocks on the top of the moving plate engage with the first and second locking slots respectively, which can quickly realize the connection between the two liquid cooling plate bodies, facilitating the rapid deployment and maintenance of the liquid cooling plate bodies.

[0015] 2. This utility model uses a temperature sensor to detect the heat output inside the manifold, transmits the signal to the control mechanism, analyzes the data, and then controls the activation of the automatic valve. This enables the automatic adjustment of the coolant flow rate of each heat exchange unit according to different heat levels, reducing energy consumption. During use, an ultrasonic oscillator prevents microchannel blockage, and a leak detection sensor monitors coolant leaks in real time. Once a leak is detected, the system automatically shuts off the coolant supply to the relevant unit, improving the practicality of the liquid cooling plate.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description
