Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation components, in particular to a plastic water cooling head rapid bubble removal structure. Background Art

[0002] Semiconductor cooling chips have broad application prospects in occasions with specific cooling needs due to their small size, no noise, and flexible size. The semiconductor chip is connected to the rated voltage, one side is cooling, and the other side is heating. The structure of the semiconductor cooling chip is similar to a sandwich cookie, with ceramic chips on both sides and a thermocouple in the middle. The surroundings are usually sealed with glue, and a water cooling head is usually used to dissipate the heat of the semiconductor cooling chip;

[0003] During the operation of the water cooling head, bubbles will accumulate at the corners of the channel when the liquid flows in its internal channel. In the prior art, the water cooling head is made of either metal or plastic. The reason for using metal is that metal has good thermal conductivity. Even if bubbles are generated during the water circulation process, the effect on the heat exchange efficiency is very small. The disadvantages of metal radiators are that the processing process is complicated, the cost is high, and the weight is heavy. During use, the inside and outside will gradually oxidize, resulting in a decrease in heat exchange efficiency.

[0004] On the contrary, the heat exchanger made of plastic material has the advantages of simple production, low cost and light weight. However, the disadvantage of the heat exchanger made of plastic material is that when bubbles appear inside, if the bubbles cannot be discharged in time and gradually grow larger, it will have a certain impact on the heat exchange efficiency and may even cause damage to the semiconductor device. In addition, in actual use, the water cooling head usually needs to cooperate with the water pump to make the water flow in the water channel move to achieve the purpose of heat exchange. As the pressure and temperature in the water channel change, bubbles will continue to be generated, which will affect the heat exchange effect. Utility Model Content

[0015] Beneficial effects of the utility model:

[0016] The utility model separates the bubbles by arranging a guide plate at the corner of the water flow channel, and the liquid continuously undergoes a diversion and cutting process during the flow, so that the bubbles are continuously divided and dispersed, and cannot be gathered together and can flow out from the water outlet, thereby achieving the removal of bubbles and avoiding affecting the energy conversion effect.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] Please refer to Figure 1-2 ;

[0023] The water-cooled head described in the utility model has the function of quickly removing bubbles, effectively reducing the influence on heat exchange, and specifically includes a shell 11 with a water inlet 12 and a water outlet 13, a transducer chamber is formed in the shell 11, and a plurality of partitions 14 are staggered in the transducer chamber, one end of the partition 14 is connected to the shell 11, and the other end has a gap with the shell 11 to form a corner, so that a winding water flow channel is formed, and the water flow channel adopts a winding design, which can make the liquid flow evenly through the heat dissipation surface and fully absorb heat. In the actual use of the cold head, because the corner is often the highest point of the liquid level when it cannot be completely horizontal, and the flow rate at the corner is relatively low, so the corner is the place where bubbles are most likely to accumulate. In this embodiment, at least one guide plate 15 is provided at the corner, and the guide plate 15 divides the corner into at least two flow channels 16;

[0024] The water channel is divided into several areas with the partition 14 as the boundary, and the initial state is that the transducer chamber is filled with liquid. When a bubble enters the first area, it reaches the corner with the flow, and the bubble is divided into two by the guide plate 15 at this time, so that the larger bubble becomes smaller, and some of the bubbles will enter the second area, while the other part of the bubbles will still be retained at the corner; preferably, the guide plate 15 is inclined to make the opening close to the shell 11 smaller, and another function of the guide plate 15 is to separate the space at the corner, so that the guide plate 15 can be used as a guide plate. The space formed by the corner, the bottom surface, and the heat dissipation surface gradually becomes smaller in the direction of the water flow, thereby increasing the flow rate of the liquid passing through the corner, thereby dispersing the bubbles staying at the corner and making them smaller and entering the second area. These very small bubbles will not gather again, but will directly enter the next area from the corner of the second area until they flow out from the water outlet 13. If there are still large bubbles, they will still go through the above process at the corner of the second area or the corner of the third area, and finally disperse the large bubbles so that they will not gather and flow out from the water outlet 13.

[0025] The utility model separates the bubbles by arranging a guide plate 15 at the corner of the water flow channel, and the liquid continuously undergoes a diversion and cutting process during the flow, so that the bubbles are continuously divided and dispersed, and cannot be gathered together and can flow out from the water outlet 13, thereby achieving the removal of bubbles and avoiding affecting the energy conversion effect.

[0026] In the embodiment of the utility model, the partition 14 is arranged to be inclined, more specifically, one end of a partition 14 near the corner faces the end of another partition 14 connected to the housing 11;

[0027] Another implementation based on the above principle is that when the application does not require the cold head to be placed completely horizontally, the water outlet is higher than the water inlet, so that the bubbles have a continuous upward channel and are easier to discharge.

[0028] In the embodiment of the utility model, the guide plate 15 is in a "C" shape, which is placed at the corner across the partition 14, and the opening is toward the end of the partition 14. The space on the side of the guide plate 15 close to the shell 11 gradually becomes smaller, that is, along the flow direction of the liquid, the flow from one area to another area gradually becomes smaller, thereby increasing the liquid flow rate. Of course, the liquid flow rate on both sides of the guide plate 15 is also increased.

[0029] In the embodiment of the utility model, a second guide plate 17 is provided between the two partitions 14. The second guide plate 17 is provided along the flow direction of the liquid. The liquid re-gathered together is diverted by the second guide plate 17, so that the liquid flows more evenly and the heat dissipation effect is improved. In practical applications, the first guide plate 15 and the second guide plate 17 can also be connected together.

[0030] In the embodiment of the utility model, the housing 11, the partition 14, the guide plate 15 and the guide plate 2 17 are integrally injection molded, which can effectively save costs.

[0031] Another usage method based on the above embodiment is that the surface of the shell 11 has an opening, and an outer frame 21 is provided on the outer periphery of the shell 11. The outer frame 21 protrudes from the opening of the shell 11 to form an embedded position. Assuming that the heat-generating component is a semiconductor refrigeration plate, its hot surface can be installed in the embedded position. Of course, the shape of the embedded position is adapted thereto. At the same time, the hot surface of the semiconductor refrigeration plate is tightly attached to the end face edge of the shell 11 to form a water flow channel. Of course, the position at the edge will be sealed by gluing or the like to prevent water leakage. Through such a design, the liquid can directly contact the heat source, so the heat energy exchange is better and the heat dissipation is faster.

[0032] Alternatively, a heat conducting plate, such as a ceramic plate, may be installed in the embedded position for packaging, thus preventing the heat source from directly contacting the liquid.

[0033] Furthermore, a groove 22 is provided between the outer frame 21 and the shell 11 , and the groove 22 is used for dispensing glue to facilitate sealing. In addition, the height of the partition 14 is less than or equal to the edge height of the shell 11 .

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementations that can be understood by those skilled in the art.
