Description

Liquid cooling row module

Technical Field

The utility model relates to a heat dissipation module indicates a liquid cooling row module especially.

Background

With the advancement and popularization of science and technology, various electronic devices or computer apparatuses have long become indispensable in daily life, such as notebook computers, desktop computers, network servers, and the like. Generally, the electronic components inside these products are heated during operation, and the high temperature is likely to cause damage to the components. Therefore, the heat dissipation mechanism is an important and necessary design for these electronic products. In addition to the general heat dissipation design using a fan to provide air flow for convection cooling or using a heat dissipation unit made of a special material for attachment to generate conduction cooling, a water cooling mechanism is also an effective and common heat dissipation design.

The principle of water-cooled heat dissipation is simply that a liquid (such as water or coolant) is generally used as a heat dissipation medium, and a water pump or pump which operates continuously is used to form a continuous circulation in the applied system. The liquid flows in closed conduits that are distributed over the surface of various electronic components (e.g., central processing units) within the system. When a relatively low temperature fluid flows through these relatively high temperature electronic components, it absorbs its heat to slow the temperature rise. Then, the heat is released by the heat exchange between the pipeline and the outside or other heat dissipation mechanisms to reduce the temperature of the liquid, and the liquid returns to the system again for circulation and heat dissipation.

However, since the internal space of a general computer device, a host or a server device is limited, it can only be utilized by the space of the installed environment, and the water-cooled heat dissipation device needs to have the design of the inflow and outflow of the pipeline, so that the installation of the pipeline is relatively complicated. Therefore, how to design a water-cooling heat dissipation structure with good heat dissipation effect, and simultaneously consider the whole pipeline configuration, reduce the occupied space to facilitate the arrangement in a narrow environment, and effectively complete the connection with other pipelines and avoid the occurrence of water leakage is the main purpose of the development of the scheme.

The first casing 13 is sandwiched between the upper cover 11 and the lower cover 12. The second casing 14 is sandwiched between the upper cover 11 and the lower cover 12. In other words, the upper cover 11 and the lower cover 12 sandwich the first casing 13 and the second casing 14 therebetween, and locate the first casing 13 and the second casing 14 at both sides, respectively. The long axis direction of the second casing 14 is parallel to the long axis direction (e.g., X axis) of the first casing 13.

The heat dissipation laminated structure 150 includes a plurality of fin tube layers 160 and a plurality of heat dissipation fin groups 15 sandwiched between the first case 13 and the second case 14. The fin tube layers 160 and the heat dissipating fin groups 15 are arranged in a manner that one layer of heat dissipating fin groups 15 is stacked on one layer of fin tube layer 160 to form a plurality of layers of alternate overlapping, in other words, the fin tube layers 160 are stacked one on another, the heat dissipating fin groups 15 are stacked one on another, and each fin tube layer 160 is stacked between any two adjacent heat dissipating fin groups 15. The fin tube layer 160 includes a plurality of fins 16. The fins 16 are juxtaposed parallel to each other, i.e., the long axis direction (e.g., the Y-axis) of each fin 16 is juxtaposed parallel to each other. The long axis direction of each fin tube 16 is orthogonal to the long axis direction (e.g., X-axis) of the first case 13. However, the present invention is not limited thereto, and in other embodiments, the heat dissipation fins, the upper cover, or/and the lower cover may be omitted.

holes

130 and 140 correspond to the fin tubes 16 to form through holes for the fin tubes 16 to pass through, so that the fin tubes 16 are communicated with the first box body 13 through the through holes 130 and the second box body 14 through the through holes 140. This embodiment illustrates that the through

holes

130, 140 have seven and five layers in a layer, and the fins 16 also have seven and five layers in a layer; in addition, there are six layers of the heat dissipating fin sets 15 overlapped alternately in multiple layers. It is to be understood that the inventive concept is not so limited.

In this embodiment, the airflow channel direction of the heat dissipating fin sets 15 is parallel to the long axis direction of the first box 13 and the long axis direction (e.g., X axis) of the second box 14, and the nozzle orientations of the fins 16 are perpendicular to the first box 13 and the second box 14, i.e., the airflow channel direction of the heat dissipating fin sets 15 is perpendicular to the nozzle orientations of the fins 16. The first box 13 and the second box 14 respectively sandwich the heat dissipating fin sets 15 on two sides, so that the other two sides of the heat dissipating fin sets 15, which are not sandwiched, are exposed, thereby providing external air flow to blow into the channels thereof to cool the working fluid (such as liquid water) in the fin tubes 16, wherein one side of the heat dissipating fin set 15, which is located at the liquid inlet 101 and the liquid outlet 102, is an air outlet side of the external air flow, and one side of the heat dissipating fin set 15, which is opposite to the air outlet side, is an air inlet side of the external air flow. In other words, each of the heat dissipating fin groups 15 includes a plurality of fins 151 arranged at intervals. An air channel 152 is formed between any two adjacent fins 151. The long axis direction of each air flow channel 152 is parallel to the long axis direction (e.g., X axis) of the first housing 13. Furthermore, in the present embodiment, the liquid cooling row module is, for example, a water cooling type or an oil cooling type liquid cooling row module, however, the present invention is not limited thereto.

The liquid inlet 101 and the liquid outlet 102 are in this embodiment illustrated as forming an outwardly protruding nozzle of relatively small bore. The lower cover 12 has two

perforations

121, 122, wherein the liquid inlet 101 is connected to the perforation 121, and the liquid outlet 102 is connected to the perforation 122. In this embodiment, the liquid inlet 101 and the liquid outlet 102 are illustrated as extending to protrude from the lower cover 12, but it is understood that the concept of the present invention is not limited thereto.

Next, the first housing 13 has a first chamber 131 and a second chamber 132 separated from each other, and the first chamber 131 and the second chamber 132 are sequentially arranged along a long axis direction (e.g., X axis) of the first housing 13. The second casing 14 has a third chamber 141 and a fourth chamber 142 separated from each other. The third chamber 141 and the fourth chamber 142 are arranged in sequence along the long axis direction (e.g., the X axis) of the second casing 14. The length of the first chamber 131 is different from the length of the third chamber 141, and the length of the second chamber 132 is different from the length of the fourth chamber 142.

In this embodiment, the first chamber 131 is designed to correspond to the first three fins 16 of each layer, the second chamber 132 is designed to correspond to the last four fins 16 of each layer, and on the other hand, the third chamber 141 is designed to correspond to the first five fins 16 of each layer, and the fourth chamber 142 is designed to correspond to the last two fins 16 of each layer, but it is understood that the present invention is not limited thereto. The liquid inlet 101 is in fluid communication with the first chamber 131. Thus, when the working fluid flows from the fluid inlet 101 into the first chamber 131, the working fluid flows according to the direction shown by the arrow in fig. 1C, i.e., flows through the first chamber 131, the third chamber 141, the second chamber 132 and the fourth chamber 142 in sequence.

As such, the first chamber 131, the first portion of the fins 16, the third chamber 141, the second portion of the fins 16, the second chamber 132, the third portion of the fins 16, and the fourth chamber 142 together form an S-shaped flow path between the first tank 13 and the second tank 14, however, the present invention is not limited thereto.

Fig. 3A and 3B are also illustrated with the upper cover 11 omitted. Therefore, as shown in fig. 3A to 3C, the number of the fins 16 is divided into three portions (not necessarily equal), hereinafter referred to as a first portion, a second portion and a third portion, the fins 16 of the second portion are located between the fins 16 of the first portion and the third portion, and the number of the fins 16 of the first portion, the second portion and the third portion is not necessarily equal. The fins 16 (e.g., three fins 16) of the first portion are respectively connected to the first chamber 131 and the third chamber 141, the fins 16 (e.g., two fins 16) of the second portion are respectively connected to the third chamber 141 and the second chamber 132, and the fins 16 (e.g., two fins 16) of the third portion are respectively connected to the second chamber 132 and the fourth chamber 142, however, the present invention is not limited to the number of the fins 16 of the first portion, the second portion and the third portion.

More specifically, in this embodiment, the working fluid flows into the third chamber 141 through the first three fins 16 of each layer, and then flows out through the last two fins 16 of each layer in the third chamber 141. Similarly, the working fluid flows into the second chamber 132 corresponding to the first two fins 16 of each layer in the second chamber 132 and then flows out of the last two fins 16 of each layer in the second chamber 132. It is understood that the present invention may be designed for other number of fins in each chamber for each layer, i.e. not limited to the examples shown in the above figures.

Furthermore, as shown in fig. 3B and 3C, in the present embodiment, the liquid inlet 101 and the liquid outlet 102 are both located on the same side of the liquid cooling module 1, for example, the liquid inlet 101 and the liquid outlet 102 are both located on the same side of the lower cover 12. The fourth chamber 142 is also in fluid communication with an outlet flow path 143. the outlet flow path 143 is also separate from the third chamber 141 and is located below the third chamber 141. In other words, the outlet flow path 143 is located below the third chamber 141, for example, the outlet flow path 143 is located between the lower cover 12 and the third chamber 141, and connects the fourth chamber 142 and the liquid outlet 102. The outlet flow passage 143 is in fluid communication with the liquid outlet 102. Thus, when the working fluid flows from the corresponding fin tube 16 into the fourth chamber 142, the working fluid flows into the outlet flow channel 143 according to the direction shown by the arrow in fig. 3C, and finally flows out of the liquid outlet 102 to the cold row module 1.

Further, in the present embodiment, the first case 13 includes a plurality of reinforcing ribs 133. The reinforcing ribs 133 are spaced apart from each other on the inner walls of the first and

second chambers

131 and 132 to reinforce the structural strength of the first casing 13. However, the present invention is not limited thereto, and in other embodiments, the second casing 14 can also have the reinforcement rib 133.

Finally, the above-disclosed embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
