Technical Field

[0001] This utility model relates to the technical field of heat sink application equipment, and in particular to a pulse water pump high-pressure flushing device applied to the internal tunnel of a heat sink component. Background Technology

[0002] Existing heat dissipation components require immersion in water for processing. Due to the internal tunnels and the complexity of the products, air bubbles are trapped inside. The overly complex structure makes it impossible to properly remove these air bubbles from the internal cavity, thus preventing the next step of ultrasonic scanning. As a result, some products have to wait for a long time before proceeding to the next step, leading to low efficiency.

[0003] Therefore, it is necessary to design a pulse water pump high-pressure flushing device for use in the internal tunnels of heat sinks to solve the above problems. Summary of the Invention

The water inlets and water outlets are all connected to the contour groove. Each water outlet is provided with a water outlet pipe, and each water outlet pipe is provided with a water outlet throttle valve at its inlet. The flow rate at the water inlet pipe is greater than the flow rate at the water outlet pipe.

[0007] Preferably, a sealing ring is provided around the upper cover plate.

[0008] Preferably, several sets of fixing holes are provided around the bottom plate and the top cover plate, and the fixing holes of the bottom plate and the fixing holes of the top cover plate are arranged in a one-to-one correspondence.

[0009] The beneficial effects of this utility model are: This technical solution uses an adjustable inlet pipe and an adjustable outlet pipe to adjust the water flow rate to achieve pressure difference, thereby filling the interior with water and removing internal air bubbles. At the same time, it can be used with simple tooling to adapt to different models of products. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Reference Figures 1 to 5 A pulse water pump high-pressure flushing device for internal tunnels of heat sink components includes a water pump 1, a flushing fixture 3 connected to the water pump via an inlet pipe 2, and an outlet pipe 4 disposed on the flushing fixture.

[0019] The water inlet pipeline 4 includes a main water pipe 41 connected to the water pump 1. The main water pipe is connected to several sets of water inlet pipes 43 through a multi-valve 42. The water inlet pipes are respectively connected to the flushing fixture. In order to limit the flow rate of different water inlet pipes, an inlet throttle valve 44 is installed at the outlet of each water inlet pipe. The water inlet flow rate is controlled by the inlet throttle valve.

[0020] The flushing fixture 3 includes a lower base plate 31, an upper cover plate 32 corresponding to the lower base plate, a contour groove 33 disposed in the upper cover plate, a plurality of water inlets 34 disposed on one side of the upper cover plate and connected to the water inlet pipes, and a plurality of water outlets 35 disposed on the other side and the top of the upper cover plate. The water inlets and the water outlets 35 are connected to the contour groove 33. Each water outlet is provided with a water outlet pipe 5, and each water outlet pipe is provided with a water outlet throttle valve 51 at the water inlet.

[0021] To prevent liquid from leaking out, a sealing ring 36 is provided around the upper cover plate. The sealing ring makes the upper cover plate and the lower bottom plate form a seal, and the contour groove forms a sealed space.

[0022] To facilitate the fixing of the flushing fixture 3, several sets of fixing holes 37 are provided around the bottom plate and the top cover plate. The fixing holes of the bottom plate and the fixing holes of the top cover plate are arranged one-to-one vertically. During assembly, the bottom plate and the top cover plate are fixed together by screws and nuts.

[0023] In order to generate internal pressure, the flow rate at the inlet pipe is made greater than that at the outlet pipe by adjusting the outlet throttle valve 51 and the inlet throttle valve, thereby controlling the internal water pressure and effectively flushing the water into the heat sink tunnel to remove internal air bubbles. In addition, the flushing water is pure water to prevent impurities from affecting the performance.

[0024] In this implementation, the heat dissipation product is installed into the contoured groove of the upper cover plate, and then the upper cover plate is installed on the lower base plate and fixed with nuts. The water pump is started to begin water intake. The inlet throttle valve is adjusted to regulate the water inflow, and the outlet throttle valve is adjusted to regulate the water outflow, ensuring that the inflow is greater than the outflow, thus creating internal water pressure. After a period of continuous flow, the internal water flushes various parts of the heat dissipation fins, removing internal air bubbles and facilitating subsequent ultrasonic scanning.

[0025] The advantages of this utility model are that the technical solution uses an adjustable inlet pipe and an adjustable outlet pipe to adjust the water flow rate and achieve pressure difference, thereby filling the interior with water and removing internal air bubbles. At the same time, it can be used with simple tooling to adapt to different models of products.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
