Description

Technical Field

[0001] This utility model relates to the field of temperature equalization plate technology, and in particular to a novel temperature equalization plate. Background Technology

[0002] Vapor chambers are widely used in various heat exchangers and coolers. They are a commonly used rapid heat conduction mechanism and the most common and efficient heat conduction element in the heat dissipation devices of electronic products today.

[0003] However, existing heat spreader structures still have some defects or shortcomings. For example, since most heat spreaders on the market are fixedly connected by brazing or laser welding, ordinary heat spreaders have problems with insufficient reliability during production or turnover, resulting in a relatively high scrap rate. At the same time, for heat spreaders with long injection channels, welding can easily cause blockage of the injection channels, which seriously affects subsequent injection processes.

One end of the liquid inlet channel is connected to the liquid storage chamber, and the other end extends into the liquid inlet protrusion. The liquid inlet protrusion is provided with a connecting channel, and the lower end of the connecting channel is connected to the liquid inlet channel. The connecting channel is used to movably connect with the liquid inlet pipe, so that coolant flows into the liquid storage chamber through the liquid inlet pipe and the liquid inlet channel. The inner end face of the liquid inlet protrusion is provided with a slag removal port for cleaning carbon-containing anti-clogging components or sealing the end of the liquid inlet channel.

[0008] In a preferred embodiment of this utility model, the cross-section of the mounting groove is circular, and the liquid storage cavity is annular.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figure 1-4 The embodiments of this utility model include:

[0022] A novel heat spreader, which is an aluminum alloy structure, includes: a heat spreader body 1, an installation groove 2, a liquid inlet protrusion 3, a connecting channel 4, a liquid inlet pipe 5, a liquid storage chamber 6, a liquid inlet flow channel 7, a slag removal port 8, and a carbon-containing anti-clogging component (or carbon rod) 9.

[0023] The mounting slot 2 is vertically installed through the center of the heat spreader body 1. The liquid inlet protrusion 3 is installed in the mounting slot 2 and connected to the inner wall of the heat spreader body 1. The liquid storage cavity 6 is installed in the heat spreader body 1 outside the mounting slot 2. The liquid storage cavity 6 is equipped with reinforcing ribs 61 and copper pillars 62. The reinforcing ribs 61 can increase the strength of the heat spreader body 1 and the liquid storage cavity 6 and improve stability. The copper pillars 62 can increase the strength while improving the uniformity and efficiency of heat conduction.

[0024] The liquid inlet channel 7, which is used to place the carbon anti-clogging component 9 or to allow coolant to flow, is located inside the heat spreader body 1. One end of the liquid inlet channel 7 is connected to the liquid storage chamber 6, and the other end extends into the liquid inlet protrusion 3.

[0025] Preferably, the cross-section of the mounting channel 2 is circular, and the liquid storage 6 is annular.

[0026] Preferably, the temperature distribution plate body 1 and the liquid inlet protrusion 3 are an integral structure.

[0027] In a further preferred embodiment, the heat spreader body 1 includes a heat spreader upper cover plate 11, a heat spreader base plate 12, and a cavity. The heat spreader upper cover plate 11 is sealed on the heat spreader base plate 12 by means of welding, bonding, fastener connection, etc., and the through groove on the heat spreader upper cover plate 11 is connected to the through groove on the heat spreader base plate 12 to form an installation through groove 2. The cavity is disposed on the heat spreader upper cover plate or on the heat spreader upper cover plate and the heat spreader base plate to form a liquid storage cavity 6.

[0028] In a further preferred embodiment, the upper cover plate 11 and the base plate 12 of the heat exchanger plate on the outer side of the mounting slot 2 are provided with a number of screw holes 13. The fixing screws pass through the screw holes 13 to connect the upper cover plate 11 and the base plate 12 of the heat exchanger plate for pre-positioning and locking during assembly.

[0029] Preferably, the protruding length of the liquid inlet bump 3 is less than half the diameter of the mounting groove 2, so as to facilitate the removal or cleaning of the carbon-containing anti-clogging component 9.

[0030] In a further preferred embodiment, multiple reinforcing ribs 61 are arranged circumferentially and at intervals within the liquid storage cavity 6, and an angle is provided between the reinforcing ribs 61 and the diameter of the liquid storage cavity 6, so as to increase the length of the reinforcing ribs 61 while ensuring the flow of coolant and improving the reinforcing effect.

[0031] A connecting channel 4 is provided on the liquid inlet protrusion 3, and the lower end of the connecting channel 4 is connected to the liquid inlet flow channel 7 for the flow of coolant or to close the liquid inlet flow channel 7. The lower part of the liquid inlet pipe 5 is movably connected to the connecting channel 4, so that the coolant can flow into the liquid storage 6 through the liquid inlet pipe 5 and the liquid inlet flow channel 7. A slag removal port 8 is provided at the bottom of the inner side wall of the liquid inlet protrusion 3. The slag removal port 8 is connected to the liquid inlet flow channel 7 for closing the end of the liquid inlet flow channel 7 after removing the carbon-containing anti-clogging component 9 in the liquid inlet flow channel 7.

[0032] More preferably, the connecting channel 4 is vertically disposed on the liquid inlet protrusion 3 and perpendicular to the liquid inlet flow channel 7.

[0033] In a further preferred embodiment, the slag removal port 8 is connected to the connecting channel 4 via the liquid inlet channel 7.

[0034] The assembly process of the heat spreader in this application includes the following steps: First, the carbon-containing anti-clogging component 9 is placed in the liquid inlet channel 7, and the outer end of the carbon-containing anti-clogging component 9 extends through the slag removal port 8 to the outside of the connecting boss 3. Then, the heat spreader upper cover plate 11 and the heat spreader base 12 are connected with screws and then welded and sealed. During this process, the carbon-containing anti-clogging component 9 can effectively prevent the liquid inlet channel 7 from being blocked, ensuring the smoothness of subsequent liquid inlet. The carbon-containing anti-clogging component 9 is removed from the liquid inlet channel 7 from the slag removal port 8 and removed from the installation through groove 2. Then, the slag removal port 8 is sealed to prevent leakage. The liquid inlet pipe 5 is inserted into the connecting channel 4, and the liquid storage chamber 6 is evacuated and injected with liquid, so that the coolant flows through the liquid inlet pipe 5 and the liquid inlet channel 7 and enters the liquid storage chamber 6. When the liquid storage chamber 6 is filled with coolant, the liquid inlet pipe 5 is pulled out, and the middle part of the liquid inlet channel 7 is sealed by laser welding technology to complete the permanent seal and form the finished heat spreader.

[0035] The beneficial effects of this novel heat spreader are: by improving the structure of the heat spreader, not only is the smooth and efficient liquid injection of the heat spreader effectively guaranteed, but it is also easy to assemble, which improves the reliability and stability of the heat spreader and increases the yield of the heat spreader.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
