Description

Technical Field

[0001] The utility model belongs to the technical field of cabinet heat dissipation, and particularly relates to a multi-channel liquid-cooled radiator. Background Technique

[0002] Cabinet heat dissipation is an important link to ensure the stable operation of electronic devices. Among them, air-cooled heat dissipation, cooling plate heat dissipation, and immersion heat dissipation are three common heat dissipation methods.

[0003] Cooling plate heat dissipation, characteristics: High-efficiency heat dissipation: The cooling plate can absorb heat from the heat source more effectively through high-efficiency heat conduction media such as liquid or heat pipes and dissipate it to the external environment. Precise temperature control: It can achieve more precise temperature control, which helps to prevent the device from overheating and ensure its operation within a safe temperature range. Compact structure: The cooling plate is designed compactly and is suitable for installation in cabinets with limited space. High cost: Compared with air-cooled heat dissipation, the manufacturing cost, R & D cost, and design cost of the cooling plate are relatively high.

[0004] In the existing cooling plate structure, when considering heat dissipation, there is redundancy in the flow channels subsequently, resulting in the failure to consider that when the device is turned on, the heat generation rate is very fast. At this time, the cooling plate is still at a relatively high temperature. By increasing the speed of the pump group, the flow rate of the coolant is increased to improve the heat exchange efficiency, but there will be a certain time delay. At this time, there may be heat accumulation in the core of the device, resulting in overheating shutdown or damage of the electronic device. Secondly, there is no backup for the cooling plate. The damage of a single device will directly lead to a sudden reduction or stop of the coolant supply. When the device is on standby waiting for repair, basic heat dissipation is still required. At this time, relying entirely on air cooling will cause damage to the device due to the existence of cooling dead spots. Content of the Utility Model

[0005] The purpose of the utility model is to provide a multi-channel liquid-cooled radiator, aiming to solve the problems raised in the background technique.

[0006] A multi-channel liquid-cooled radiator includes,

[0007] A heat preservation shell;

[0008] A channel component, which is arranged on the inner wall of the heat preservation shell. Among them: the channel component includes a cooling plate, a rapid cooling tube, a heat conduction plate, a flow channel, a control tube, a buckle groove, a heat conduction layer, and a heat conduction surface. The cooling plate is embedded in the groove opened on the inner wall of the heat preservation shell. The flow channel is opened on the axis of the inner wall of the cooling plate. The control tube is fixedly arranged on both sides of the outer wall of the cooling plate. The control tube is communicated with the flow channel. The buckle groove is opened on the top of the outer wall of the cooling plate. The rapid cooling tube is embedded in the inner wall of the buckle groove. One side of the outer wall of the heat conduction plate is attached to the top of the outer wall of the rapid cooling tube. The heat conduction layer is embedded in the space formed by the heat conduction plate and the buckle groove. The heat conduction surface is opened on the top of the outer wall of the heat conduction plate.

[0009] Further, bolts are threadedly connected to the top corners of the outer wall of the heat conduction plate, and the bottom ends of the bolts are threadedly connected to the top corners of the outer wall of the cooling plate.

[0028] In a specific embodiment of the present utility model, the channel assembly can achieve efficient control of coolant flow and cooling function. When the device is in the standby state, a large amount of heat is often not generated. At this time, only the rapid cooling pipe 3 can be turned on. When accumulated heat is generated, the coolant supply of the flow channel 201 can be turned on, which can improve the heat exchange efficiency. At the same time, when any one of the devices attached to the rapid cooling pipe 3 and the flow channel 201 and the attached device fails, and the other group is intact, it can take over for cooling, avoiding equipment overheating and downtime due to failures, and improving work stability. First, the rapid cooling pipe 3 is connected to an external coolant supply device through a hose and a valve, and the flow channel 201 is connected to an external coolant supply device. When the device is in standby, only coolant is supplied for flow, and heat exchange is carried out through the heat conduction layer 301 and the heat conduction plate 4 to assist in heat dissipation. When the device generates accumulated heat, coolant is supplied to the rapid cooling pipe 3 at the same time to accelerate the heat exchange efficiency. When the device fails, the intact group supplies coolant to ensure that the device does not overheat, saving time and assisting the staff in maintenance.

[0035] Specifically, an anti-adhesion film is sprayed on the inner wall of the flow channel 201.

[0036] In a specific embodiment of the present utility model, an anti-adhesion film is sprayed on the inner wall of the flow channel 201, which can avoid the adhesion of impurities in the coolant.

[0037] Specifically, the outer wall of the heat preservation shell 1 is wrapped with a polyurethane layer.

[0038] In a specific embodiment of the present utility model, the outer wall of the heat preservation shell 1 is wrapped with a polyurethane layer, which can further improve the heat preservation effect.

[0039] Working principle:

[0040] The channel assembly can achieve efficient control of coolant flow and cooling function. When the device is in the standby state, a large amount of heat is often not generated. At this time, only the rapid cooling pipe 3 can be turned on. When accumulated heat occurs, the coolant supply of the flow channel 201 can be turned on, which can improve the heat exchange efficiency. At the same time, when a failure occurs in any one of the rapid cooling pipe 3 and its attached equipment and the flow channel 201 and its attached equipment, and the other group is intact, it can take over for cooling to avoid equipment overheating and downtime due to failures, and improve work stability. First, the rapid cooling pipe 3 is connected to an external coolant supply device through a hose and a valve, and the flow channel 201 is connected to the external coolant supply device. When the device is in standby, only the flowing coolant is supplied, and heat exchange is carried out through the heat conduction layer 301 and the heat conduction plate 4 to assist in heat dissipation. When the device generates accumulated heat, coolant is supplied to the rapid cooling pipe 3 at the same time to accelerate the heat exchange efficiency. When a failure occurs in the device, the intact group supplies the coolant to ensure that the device does not overheat, saves time, and assists the staff in maintenance.
