Description

Technical Field

[0001] The utility model relates to the technical field of vapor chambers, in particular to a divertable vapor chamber. Background Art

[0002] The development of intelligent devices and the Internet of Things (IoT) has accelerated chip performance requirements. Highly integrated chips are associated with higher heat flux densities, severely impacting device response rates. However, single-phase cooling technologies, which simply add fans and heat sinks to the chip, are no longer sufficient to address the high heat flux densities of existing chips. Compared to traditional air and liquid cooling technologies, phase change heat transfer is one of the most widely researched thermal control technologies. In particular, composite heat dissipation modules, which utilize vapor chamber technology for evaporation and condensation of liquid working fluids, are widely used in cooling high-power electronic components such as laptops and mobile devices.

[0003] For example, Chinese patent publication number CN208489335U describes a water-cooled plate. The plate comprises a plate body and handles on both sides of the plate body. The plate body comprises a bottom plate, an intermediate plate, and a cover plate, arranged in order from bottom to top. The bottom plate is provided with symmetrically distributed flow channels, which are connected by a main flow channel and branch flow channels. The branch flow channels are arranged in parallel and then in series. The bottom plate, intermediate plate, and cover plate are brazed together. The plate body is provided with a liquid inlet on the top and a liquid outlet on the side. Coolant flows from the liquid inlet into the main flow channel.

[0004] However, in the above solution, it is not convenient to shield each diversion pipe when the device is in use, resulting in a larger water flow in the diversion pipe closer to the water inlet pipe, making the water flow in each diversion pipe less uniform and resulting in lower heat dissipation efficiency.

The water inlet groove, guide groove, vertical groove and horizontal groove are rectangular when viewed from above, a drainage groove is provided on the side wall at one end of the horizontal groove, and the drainage groove is connected to the outside world. A plurality of diversion grooves are provided on the side wall of the guide groove, and one end of the plurality of diversion grooves is connected to the horizontal groove, and one end of each of the horizontal grooves is provided with a blocking ball, and the plurality of blocking balls are arranged in different sizes, and the side of the plurality of blocking balls closer to the water inlet groove is larger.

[0008] As a further improvement of the present technical solution: the plurality of diversion grooves are all arranged in an arc-shaped curved shape.

[0009] As a further improvement of the technical solution: a heat conducting rod is fixedly connected to each of the diversion grooves, and the bottom of each of the heat conducting rods passes through the side wall of the heat spreader body.

[0010] As a further improvement of this technical solution: each of the heat-conducting rods is made of copper.

[0011] As a further improvement of the technical solution: the surfaces of the plurality of blocking balls are sprayed with a corrosion-resistant layer.

[0012] Compared with the existing technology, the beneficial effect of the present invention is that the device can improve the uniformity of water flow in each diversion groove through the mutual cooperation of components such as heat-conducting rods, vertical grooves, sealing balls, drainage grooves, etc., thereby improving the heat dissipation performance of each position of the heat spreader, and the operation is simple, convenient and fast.

[0023] See also Figure 1-3 In the embodiment of the present invention, a divertable heat spreader includes a heat spreader body 1, a water inlet groove 7 is opened on the side wall of the heat spreader body 1, a guide groove 9 is opened on the side wall at one end of the water inlet groove 7, a vertical groove 2 is opened on the side wall at one end of the guide groove 9, and a horizontal groove 5 is opened on the side wall at one end of the vertical groove 2. The water inlet groove 7, the guide groove 9, the vertical groove 2, and the horizontal groove 5 are rectangular when viewed from above, and a drainage groove 6 is opened on the side wall at one end of the horizontal groove 5. The drainage groove 6 is connected to the outside world, and a plurality of diversion grooves 3 are opened on the side wall of the diversion groove 9. One end of the plurality of diversion grooves 3 is connected to the horizontal groove 5, and one end of each horizontal groove 5 is provided with a blocking ball 8. The plurality of blocking balls 8 are arranged in different sizes. The closer the side of the plurality of blocking balls 8 is to the water inlet groove 7, the larger it is. The surfaces of the plurality of blocking balls 8 are sprayed with a corrosion-resistant layer.

[0024] See also Figure 2-3 The plurality of diversion grooves 3 are all arranged in an arc-shaped curved shape, thereby increasing the contact area between the water flow in the plurality of diversion grooves 3 and the heat spreader body 1, thereby improving the heat dissipation efficiency of the heat spreader body 1.

[0025] See also Figure 1-3A heat-conducting rod 4 is fixedly connected to each diversion groove 3, and the bottom of each heat-conducting rod 4 passes through the side wall of the heat-spreading plate body 1. Through the provided heat-conducting rod 4, heat can be conducted to multiple diversion grooves 3. The heat-conducting rod 4 contacts the water flow, thereby improving the heat dissipation efficiency of the heat-spreading plate body 1. Multiple heat-conducting rods 4 can also block the water flow, thereby increasing the time that the water flow stays in the multiple diversion grooves 3 and improving the heat dissipation efficiency of the heat-spreading plate body 1.

[0026] See also Figure 1-3 Each heat conducting rod 4 is made of copper, which has good thermal conductivity, thereby facilitating the improvement of the heat dissipation efficiency of the heat spreader body 1 .

[0027] The working principle of the present invention is as follows: cold water enters the guide groove 9 through the water inlet groove 7, and enters multiple diversion grooves 3 and vertical grooves 2 through the guide groove 9. The water flow can be blocked by the multiple blocking balls 8, so that the water flow flowing in the multiple diversion grooves 3 is more uniform, thereby improving the heat dissipation performance of the heat spreader body 1. Then the water flows through the multiple diversion grooves 3 and the vertical grooves 2 to the horizontal groove 5, and finally flows out through the drainage groove 6, thereby realizing circulating heat dissipation. The curved setting of the multiple diversion grooves 3 and the multiple heat-conducting rods 4 can extend the residence time of the water flow in the multiple diversion grooves 3, thereby improving the heat dissipation efficiency of the heat spreader body 1.
