[0059] Figure 5 FIG. 4 is a sectional view of the multi-point spray cold plate device of the first embodiment of the present disclosure. Referring to Figures 3 to 5 One side of the partition member 300 and the other side of the flow guide member 200 define a water inlet cavity 201. Specifically, the flow guide member 200 comprises a partition plate 203 partitioning two surfaces of the flow guide member 200. The other surface of the flow guide member 200 is provided with an upper recess 201a. The partition member 300 comprises a cover plate 310, and one surface of the cover plate 310 closes the upper recess 201a of the flow guide member 200 to define the water inlet cavity 201.

The outer casing 400 covers the other side of the partition member 300 to form a water collection cavity 401. The outer casing 400 and the partition member 300 may also be integrally formed, and this disclosure is not limited thereto. The outer casing 400 has a water inlet pipe 410 communicating with the water inlet cavity 201 and a water outlet 420 communicating with the water collection cavity 401.

In this embodiment, the water inlet cavity 201 is located between the heat exchange chamber 202 and the water collection cavity 401, and each drain pipe 220 passes through the water inlet cavity 201 and communicates with the heat exchange chamber 202 and the water collection cavity 401. Specifically, each drain pipe 220 passes through the partition member 300 and communicates with the water collection cavity 401.

[0061] Figure 6 This is a top view of the guide member 200 of the multi-point spray cold plate device according to the first embodiment of this disclosure. (See also...) Figure 5 and Figure 6 The multiple water inlet pipes 210 are arranged in a matrix, the multiple drain pipes 220 are arranged in a matrix, and the multiple water inlet pipes 210 and the multiple drain pipes 220 are interspersed.

[0062] In this embodiment, the heat exchanger 100 absorbs heat energy generated by a heat source by contacting the side opposite to the heat exchange surface 101 with a heat source. The heat source may be an operating electronic component such as a central processing unit (CPU) or a graphics processing unit (GPU). Working fluid is injected into the water inlet chamber 201 through the water inlet pipe 410 of the outer casing 400. The working fluid can be a fluid that is flowable or capable of undergoing a gas-liquid phase change, such as water, refrigerant, organic liquid, or inorganic liquid. The working fluid is evenly distributed in the water inlet chamber 201 to each water inlet pipe 210. The working fluid is directly sprayed onto the heat exchange surface 101 through each water inlet pipe 210, where it undergoes heat exchange in the heat exchange chamber 202 and absorbs heat. After impacting the heat exchange surface 101, the working fluid diffuses and reverses direction, flowing into adjacent drain pipes 220. The flow field of the working fluid creates a negative pressure at the periphery of the inlet pipe 210 corresponding to the adjacent drain pipe 220, thus guiding the working fluid to flow in reverse into each of the adjacent drain pipes 220. The working fluid passes through the drain pipe 220 and through the inlet chamber 201 to the collection chamber 401. The hot working fluid is collected in the collection chamber 401 and discharged through the outlet 420 to release the heat energy of the multi-point spray cold plate device.

[0063] Depending on the pressure of the injected working fluid, a phase change may occur. The aforementioned heat dissipation process can be performed using a single-phase liquid working fluid. The working fluid expands and cools as it passes through the inlet pipe 210, thereby improving the heat exchange efficiency with the heat exchanger 100. The working fluid may absorb heat and vaporize upon contact with the heat exchange surface 101, absorbing more heat energy through this phase change. If a higher-pressure working fluid is input and a smaller-diameter inlet pipe 210 is used, the working fluid may also vaporize after passing through the inlet pipe 210.

A heat exchange chamber 202 is formed between one side of the flow guide 200 and the heat exchange surface 101. The flow guide 200 has a plurality of water inlet pipes 210 arranged facing the heat exchange surface 101 and a plurality of drain pipes 220 arranged away from the heat exchange surface 101. In this embodiment, a recess 202a is provided on one side of the flow guide 200, and the aforementioned heat exchanger 100 closes the recess 202a with its heat exchange surface 101 to form the heat exchange chamber 202. A water inlet cavity 201 is formed between one side of the separator 300 and the other side of the guide member 200. Specifically, the guide member 200 includes a partition 203 separating the two sides of the guide member 200, and an upper recess 201a is provided on the other side of the guide member 200. The separator 300 includes a cover plate 310, one side of which closes the upper recess 201a of the guide member 200 to form the water inlet cavity 201. The aforementioned plurality of water inlet pipes 210 and the plurality of drain pipes 220 are all provided on the partition 203. The aforementioned water inlet pipes 210 can be in the form of a round pipe, a polygonal pipe, an irregularly shaped pipe, a nozzle, an opening with unequal upper and lower cross sections, or an opening with equal upper and lower cross sections.

[0065] An outer casing 400, a flow guide 200, and a partition 300 are stacked and locked together on the heat exchanger 100. The outer casing 400 covers the other side of the partition 300, forming a water collection chamber 401. The outer casing 400 has a water inlet pipe 410 communicating with the water inlet chamber 201 and a water outlet 420 communicating with the water collection chamber 401. The water inlet pipe 410 may also be provided on the partition 300, and this disclosure is not limited thereto. In this embodiment, the water inlet chamber 201 is located between the heat exchange chamber 202 and the water collection chamber 401, and each drain pipe 220 passes through the water inlet chamber 201 and communicates with the heat exchange chamber 202 and the water collection chamber 401. Specifically, each drain pipe 220 passes through the partition 300 and communicates with the water collection chamber 401.

Multiple heat-conducting columns 110 are erected on the heat exchange surface 101 of the heat exchange component 100, and the multiple heat-conducting columns 110 are respectively aligned with the multiple drain pipes 220.

[0066] In this embodiment, the heat exchanger 100 absorbs heat energy generated by a heat source by contacting the side opposite to the heat exchange surface 101 with a heat source. The heat source may be an operating electronic component such as a central processing unit (CPU) or a graphics processing unit (GPU). Working fluid is injected into the water inlet chamber 201 through the water inlet pipe 410 of the outer casing 400. The working fluid can be a fluid that is flowable or capable of undergoing a gas-liquid phase change, such as water, refrigerant, organic liquid, or inorganic liquid. The working fluid is evenly distributed in the water inlet chamber 201 to each water inlet pipe 210. The working fluid is directly sprayed onto the heat exchange surface 101 through each water inlet pipe 210, where it undergoes heat exchange in the heat exchange chamber 202 and absorbs heat. After impacting the heat exchange surface 101, the working fluid diffuses and reverses direction, flowing into adjacent drain pipes 220. The flow field of the working fluid creates a negative pressure at the periphery of the inlet pipe 210 corresponding to the adjacent drain pipe 220, thus guiding the working fluid to flow in reverse into the adjacent drain pipes 220. The heat-conducting column 110 on the heat exchange surface 101 can guide the working body to converge into its corresponding drain pipe 220, and can further exchange heat with the working fluid. The working fluid passes through the drain pipe 220 and through the inlet chamber 201 to the collection chamber 401. The hot working fluid is collected in the collection chamber 401 and discharged through the outlet 420 to release the heat energy of the multi-point spray cold plate device.

The plurality of water inlet pipes 210 are arranged in a matrix, and the plurality of drain pipes 220 are arranged in a matrix, with the plurality of water inlet pipes 210 and the plurality of drain pipes 220 interspersed. The aforementioned water inlet pipes 210 can be in the form of a circular pipe, a polygonal pipe, an irregularly shaped pipe, a nozzle, an opening with unequal upper and lower cross sections, or an opening with equal upper and lower cross sections.

[0070] In this embodiment, the heat exchanger 100 is a cover with a recess 202a. The heat exchanger 100 closes the recess 202a with its heat exchange surface 101 to form a heat exchange chamber 202. The inner bottom surface of the recess 202a is defined as the heat exchange surface 101 on the heat exchanger 100. The heat exchange surface 101 is planar and has multiple recesses 102, which are respectively aligned with multiple water inlet pipes 210. Specifically, the water inlet pipes 210 can be inserted into the aligned recesses 102 but are spaced apart from the bottom of the recesses 102.

[0071] A water inlet cavity 201 is formed between one side of the separator 300 and the other side of the guide member 200. Specifically, the guide member 200 includes a partition 203 separating the two sides of the guide member 200, and an upper recess 201a is provided on the other side of the guide member 200. The separator 300 includes a cover plate 310, one side of which closes the upper recess 201a of the guide member 200 to form the water inlet cavity 201. The aforementioned plurality of water inlet pipes 210 and plurality of drain pipes 220 are all disposed on the partition 203.

[0072] An outer casing 400, a flow guide 200, and a partition 300 are stacked and secured to the heat exchanger 100. The outer casing 400 covers the other side of the partition 300, forming a water collection chamber 401. The outer casing 400 has a water inlet pipe 410 communicating with the water inlet chamber 201 and a water outlet 420 communicating with the water collection chamber 401. The water inlet pipe 410 may also be located on the partition 300, and this disclosure is not limited thereto. In this embodiment, the water inlet chamber 201 is located between the heat exchange chamber 202 and the water collection chamber 401, and each drain pipe 220 passes through the water inlet chamber 201 and communicates with the heat exchange chamber 202 and the water collection chamber 401. Specifically, each drain pipe 220 passes through the partition 300 and communicates with the water collection chamber 401.

[0073] In this embodiment, the heat exchanger 100 absorbs heat energy generated by a heat source by contacting the side opposite to the heat exchange surface 101 with a heat source. The heat source may be an operating electronic component such as a central processing unit (CPU) or a graphics processing unit (GPU). Working fluid is injected into the water inlet chamber 201 through the water inlet pipe 410 of the outer casing 400. The working fluid can be a fluid that is flowable or capable of undergoing a gas-liquid phase change, such as water, refrigerant, organic liquid, or inorganic liquid. The working fluid is evenly distributed in the water inlet chamber 201 to each water inlet pipe 210. The working fluid is directly sprayed onto the heat exchange surface 101 through each water inlet pipe 210, where it undergoes heat exchange in the heat exchange chamber 202 and absorbs heat. After impacting the heat exchange surface 101, the working fluid diffuses and reverses direction, flowing into adjacent drain pipes 220. The flow field of the working fluid creates a negative pressure at the periphery of the inlet pipe 210 corresponding to the adjacent drain pipe 220, thus guiding the working fluid to flow in reverse into the adjacent drain pipes 220. When the working fluid is sprayed from the inlet pipe 210 into the recess 102 on the heat exchange surface 101, it can be guided to reverse by the inner wall of the recess 102, and the working fluid can further exchange heat with the heat exchange element 100 through the inner wall of the recess 102. The working fluid passes through the drain pipe 220 and through the inlet cavity 201 to the collection cavity 401. The hot working fluid is collected in the collection cavity 401 and discharged through the outlet 420 to release the heat energy of the multi-point spray cold plate device.

[0074] Depending on the pressure of the injected working fluid, the working fluid may undergo a phase change. The aforementioned heat dissipation process can be performed using a single-phase liquid working fluid. The working fluid expands and cools as it passes through the inlet pipe 210, thereby improving the heat exchange efficiency with the heat exchanger 100. The working fluid may absorb heat and vaporize upon contact with the heat exchange surface 101, absorbing more heat energy through this phase change. If a higher-pressure working fluid is input and a smaller-diameter inlet pipe 210 is used, the working fluid may also vaporize after passing through the inlet pipe 210.

[0075] In summary, the multi-point spray cold plate device disclosed herein has a water inlet pipe 210 arranged toward the heat exchange surface 101, which enables the working fluid to be directly and uniformly delivered to various points on the heat exchange surface 101 to avoid the working fluid from flowing around on the heat exchange surface 101 and causing uneven temperature when passing through various points on the heat exchange surface 101.
