Description

Technical field

[0001] The present invention relates to a structure of an integrally formed liquid collection container and a method for its manufacture. State of the art

[0002] A liquid cooling radiator assembly typically comprises a liquid cooling radiator, a liquid cooling block, and a liquid line. The liquid line is connected between the liquid cooling radiator and the liquid cooling block. The liquid line circulates the liquid within the liquid cooling radiator and the liquid cooling block. After the liquid absorbs heat from the liquid cooling block, it flows into the liquid cooling radiator to dissipate the heat. Once the heat is dissipated, the liquid flows back into the liquid cooling block. In the prior art, the liquid injection port of the liquid reservoir and the liquid reservoir of the liquid cooling radiator are designed and manufactured separately.The liquid collection container has a mounting hole, after which the liquid injection opening of the liquid collection container is welded to the mounting hole of the liquid collection container.

[0003] Document CN 201837296 U describes a liquid collection container with openings into which screws with sealing rings are screwed. The screw head is located outside the surface of the collection container, so it is not received in a stepped hole. Furthermore, there is no protruding part with a liquid injection port on an inner wall surface of the liquid collection container. The heat exchanger described in document US 6619380 B1 has a drain opening and a plug, but also no inwardly protruding part and no stepped hole to receive the plug head.

[0004] Document JP 2005-188381 A describes a sealed reserve tank system with a water injection port and a sealing plug. Due to the complex design of the device shown therein, an integral assembly is not possible. Therefore, only separate manufacturing of the injection port and reserve tank followed by welding is feasible.

[0005] Document WO 2006 / 042680 A1 shows a heat exchanger with a stepped channel and an insertable stepped piston, with a flange protruding from the stepped channel.

[0006] This conventional design has numerous disadvantages, for example (1) the liquid injection port of the liquid collection tank is welded to the mounting hole of the liquid collection tank, raising concerns about leak tightness; (2) the two components must be manufactured separately and then welded together, which is labor-intensive and time-consuming, limits production efficiency, and is not advantageous for controlling production costs; (3) the liquid injection port of the liquid collection tank is exposed protruding from the outside of the liquid collection tank, which occupies space on the outside of the liquid collection tank and complicates the application and arrangement of the liquid cooling radiator. Object of the invention

[0007] In view of the disadvantages of the prior art, the main objective of the present invention is to provide a structure for an integrally formed liquid collection container and a method for its manufacture, thereby solving the problem of having to design and weld the liquid injection port of the liquid collection container and the liquid collection container of the liquid cooling radiator separately. The present invention offers the advantages of leak tightness, ease of manufacture, and a compact design. Technical solution

[0008] This problem is solved by a setup having the features of claim 1 and by a method having the features of claim 8.

[0009] Accordingly, to achieve the above-mentioned goal, the following is provided according to the present invention: An integrally formed liquid collection container assembly comprises an integrally formed liquid collection container, a screw, and a leak-proof sealing ring. A projecting portion with a liquid injection port is integrally formed on an inner wall surface of the liquid collection container. The liquid injection port has an internally threaded hole and a stepped hole for receiving the screw head and the leak-proof sealing ring. The internally threaded hole connects to the interior of the liquid collection container. The stepped hole connects to the internally threaded hole and an exterior surface of the liquid collection container. The leak-proof sealing ring is positioned between the screw head and an inner face of the stepped hole. The screw is screwed into the internally threaded hole.When the screw is tightened, the leak-proof sealing ring is pressed in by the screw head, so that the leak-proof sealing ring is deformed and clamped between the screw head and the inner face of the stepped hole to prevent leakage.

[0010] A method for manufacturing an integrally formed liquid collection container assembly comprises the following steps: Step 1: an integrally formed liquid collection vessel formed by forging and drawing, wherein a projecting part with a liquid injection port is integrally formed on an inner wall surface of the liquid collection vessel; the liquid injection port having a hole connected to an interior of the liquid collection vessel and a stepped hole connected to the hole and an exterior of the liquid collection vessel; Step 2: Threading the hole to form an internal threaded hole; Step 3: a screw which is inserted through the leak-proof sealing ring and screwed into the internal threaded hole, whereby when the screw is tightened the leak-proof sealing ring is pressed in through the screw head of the screw, so that the leak-proof sealing ring is deformed and clamped between the screw head and an inner end face to prevent leakage.

[0011] Compared to the prior art, the present invention offers obvious advantages and beneficial effects. This is particularly evident from the technical solutions described above. A projecting portion with a liquid injection port is integrally formed on the inner wall surface of the liquid collection tank, thus solving the problem of having to design the liquid injection port of the liquid collection tank and the liquid collection tank of the liquid cooling radiator separately and then weld them together. The present invention offers the advantages of leak-proof construction, ease of manufacturing, and a compact design. This technical solution can be widely applied.

Detailed description of preferred embodiments

[0012] The Fig. Figures 1 to 13 show the specific structure of several embodiments of the present invention.

[0013] An assembly of an integrally formed liquid collection container 10 comprises an integrally formed liquid collection container 10, a screw 40 and a leak-proof sealing ring 50. Preferably, the liquid collection container 10 is formed by forging or drawing.

[0014] A projecting part 20 with a liquid injection opening 30 is integrally formed on the inner wall surface of the liquid collection container 10. The liquid injection opening 30 has an internally threaded hole 31 and a stepped hole 32 for receiving a screw head 41 of the screw 40 and the leak-proof sealing ring 50. The internally threaded hole 31 is connected to the interior of the liquid collection container 10. The stepped hole 32 is connected to the internally threaded hole 31 and the exterior of the liquid collection container 10.

[0015] The leak-proof sealing ring 50 is positioned between the screw head 41 of the screw 40 and the inner face A of the stepped hole 32. The screw 40 is screwed into the internally threaded hole 31. When the screw 40 is tightened, the leak-proof sealing ring 50 is pressed in by the screw head 41, causing it to deform and be wedged between the screw head 41 and the inner face A of the stepped hole 32, thus preventing leakage. The outer face of the screw head 41 is lower than or flush with an outer wall surface of the liquid collection container 10. This solves the problem of the liquid injection opening 30 protruding from the liquid collection container 10, as is typical in the prior art.

[0016] Preferably, the overall height of the screw head 41 and the leak-proof sealing ring 50 is greater than the depth of the stepped hole 32. This provides sufficient clearance for the screw head 41 to press in and deform the leak-proof sealing ring 50 to fill the stepped hole 32. If the overall height of the screw head 41 and the leak-proof sealing ring 50 is equal to or less than the depth of the stepped hole 32, the screw head 41 will be lower than the outer wall surface of the liquid collection container 10, thus being slightly countersunk into the stepped hole 32. The deformation and sealing effect of the leak-proof sealing ring 50 can still be achieved.

[0017] The Fig. Figures 2 to 6 show that the stepped hole 32 has a first stepped hole 321 and a second stepped hole 322, which are formed continuously from the outside to the inside and are connected to each other. The first stepped hole 321 is larger than the second stepped hole 322. The leak-proof sealing ring 50 is provided in the second stepped hole 322. Before the leak-proof sealing ring 50 is pressed through the screw head 41, the leak-proof sealing ring 50 projects beyond the first stepped surface B of the first stepped hole 321. When the screw 40 is tightened, the leak-proof sealing ring 50 is pressed in by the screw head 41 until the screw head 41 abuts the first stepped surface B, so that the leak-proof sealing ring 50 is deformed to fill the second stepped hole 322 and thereby prevent leakage.

[0018] The injection port 30 is formed integrally on any side wall of the liquid collection container 10. The liquid injection port 30 and a screw connection for the water hose 60 on the liquid collection container 10 are provided on the same or on different sides of the liquid collection container 10. For example, the ones in the Fig. The liquid injection opening 30 shown in Figure 1 and the screw connection for the water hose 60 on the liquid collection container 10 are provided on different sides. The [details of the information in the figure] Fig. The liquid injection port 30 and the screw connection for the water hose 60 on the liquid collection container 10 are located on the same side. The liquid injection port 30 can be located at either the left or right end of the liquid collection container 10. In short, besides the connection side of the liquid collection container 10 and the flow channel, other positions may also be suitable depending on requirements.

[0019] The Fig. 3 and Fig. 13 show that the form of the in the Fig. The preceding part 20 shown in section 3 is defined such that it corresponds to the shape of the liquid injection port 30. The part shown in the Fig.The projecting part 20 shown in Figure 13 is formed integrally with the adjacent side wall, which increases the structural strength of the projecting part 20, extends the service life of the liquid injection port 30 during operation, simplifies disassembly and locking, and also protects it from damage. If space is limited, the projecting part 20 is formed integrally with the adjacent side wall to prevent a gap that could form between the projecting part 20 and the adjacent side wall. This embodiment is easy to design and manufacture.

[0020] Next, the present invention relates to a method for manufacturing the structure of the integrally formed liquid collection container 10, comprising the following steps: Step 1, an integrally formed liquid collection container 10, formed by forging and drawing; on the inner wall surface of the liquid collection container 10, a projecting part 20 with a liquid injection opening 30 is formed integrally; the liquid injection opening 30 has a hole that is connected to the interior of the liquid collection container 10, while a stepped hole 32 is connected to the hole and to the outside of the liquid collection container 10; Step 2, threading the hole to form an internal threaded hole 31; Step 3: A screw 40 is inserted through a leak-proof sealing ring 50 and screwed into the internally threaded hole 31. When the screw 40 is tightened, the leak-proof sealing ring 50 is pressed in by the screw head 41 of the screw 40, so that the leak-proof sealing ring 50 is deformed and clamped between the screw head 41 and the inner face A of the stepped hole 32 to prevent leakage.

[0021] Preferably, in step 1, the stepped hole 32 has a first stepped hole 321 and a second stepped hole 322, which are formed continuously from the outside to the inside and are connected to each other. In step 3, the leak-proof sealing ring 50 is arranged in the second stepped hole 322, the leak-proof sealing ring 50 being higher than the first stepped surface B of the first stepped hole 321. When the screw 40 is tightened, the leak-proof sealing ring 50 is pressed in by the screw head 41 until the screw head 41 abuts the first stepped surface B (the first stepped surface B here corresponds to the inner end face A of the stepped hole 32), so that the leak-proof sealing ring 50 is deformed to fill the second stepped hole 322 and thereby prevent leakage.

[0022] It should be noted that the liquid collection container 10 is preferably made of a heat-dissipating metallic material. This can be, for example, stainless steel, aluminum, iron, or stainless steel.
