Description

Technical Field

[0001] The present disclosure relates to the technical field of heat dissipation devices, and particularly to a pressure regulating device and a test system. Background Art

[0002] In a notebook computer, a heat dissipation module is usually used to dissipate heat from chips such as a CPU or a GPU. Since the heat dissipation module will exert a certain pressure on the chip, if the pressure is too large, the chip may be damaged; if the pressure is too small, there will be an air gap between the heat dissipation module and the chip due to insufficient contact, resulting in the inability to effectively transfer heat from the chip to the heat dissipation module; if the pressure is uneven, only part of the chip will be in contact with the heat dissipation module, and the local pressure on the chip will be too large, which may not only cause chip damage but also prevent the other side of the chip from being effectively cooled. Therefore, during the research and development of the heat dissipation module of a notebook computer, it is necessary to design the pressure of the heat dissipation module on chips such as a CPU or a GPU.

[0003] When debugging the pressure on the chip of the existing notebook computer heat dissipation module, usually the pressure required by each pressure structure needs to be calculated theoretically first, and then the heat dissipation module is directly sampled. After that, the indentation pressure of the heat dissipation module is tested. If the requirements are met, the design is completed; if not, the pressure of the pressure structure of the heat dissipation module needs to be adjusted according to the test results and sampled again. First, this solution cannot consider the influence of the deformation of the main board during the locking process, nor can it accurately consider the reaction force of other components on the heat dissipation module; second, the indentation and pressure of the module usually do not meet the requirements during the initial sampling, and multiple samplings are required. The time for each sampling is 2 to 3 weeks. Therefore, the pressure design often takes more than 2 months to complete, with high costs and low efficiency. Summary of the Utility Model

[0004] The present disclosure provides a pressure regulating device and a test system to at least solve the above technical problems existing in the prior art.

[0005] According to a first aspect of the present disclosure, there is provided a pressure regulating device, comprising:

[0006] A housing;

[0007] A locking assembly sleeved in the housing, and a locking end of the locking assembly extends out of the housing; and

[0008] An adjusting assembly, including a movable sleeve and an elastic member. The movable sleeve is located in the housing and is slidably connected to the housing. The elastic member is disposed between the movable sleeve and the housing and is arranged along the axial direction of the housing. The movable sleeve and the elastic member are sleeved outside the locking assembly;

[0009] Wherein, a pressure display part is arranged on the outer periphery of the housing, and the pressure display part is configured to correspond to the pressure received by the elastic member.

[0010] In an implementable embodiment, the movable sleeve includes a connecting part and an abutting part. The connecting part is configured to be adapted to the inner diameter of the housing so that the movable sleeve can slide axially along the housing.

[0011] In an implementable embodiment, a limiting protrusion is arranged on the connecting part, a guiding groove is axially formed in the housing, the limiting protrusion is located in the guiding groove, and the pressure display part is arranged beside the guiding groove.

[0012] In an implementable embodiment, the housing includes an opposite open end and a mounting end. The movable sleeve is located at the open end, the locking assembly is connected to the housing through the mounting end, and the housing is further provided with a mounting groove which is communicated with the open end and the guiding groove.

[0013] In an implementable embodiment, the elastic member includes an opposite first end and a second end. The first end is abutted and limited by the mounting end, and the second end abuts against the connecting part.

[0014] In an implementable embodiment, the locking assembly further includes an operating end. The locking end extends into the housing through the mounting end and penetrates out, and the operating end abuts against the mounting end.

[0015] In an implementable embodiment, the mounting groove includes a first section and a second section. The first section is parallel to the guiding groove and communicated with the open end, and the second section is perpendicular to the guiding groove and is used for connecting the first section and the guiding groove.

[0016] In an implementable embodiment, the outer diameter of the abutting part is smaller than the outer diameter of the connecting part.

[0018] In an implementable embodiment, a test paper is further included, and the test paper is arranged between the heat dissipation module and the main board.

[0019] In the present disclosure, since the pressure regulating device includes a locking component for locking and fixing the pressure component to be regulated, after the pressure component to be regulated is locked and fixed, the movable sleeve abuts against the pressure component to be regulated. As the locking continues, the movable sleeve applies a locking pressure to the pressure component to be regulated. Due to the interaction of forces, the movable sleeve displaces axially along the housing, and the elastic member undergoes elastic deformation and is compressed.

[0030] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0031] The embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings.

[0032] Referring to Figures 1 to 5 As shown, a pressure regulating device according to an exemplary embodiment of the present disclosure includes a housing 1, a locking assembly 2, and an adjusting assembly 3. The locking assembly 2 is sleeved in the housing 1, and the locking end 21 of the locking assembly 2 extends out of the housing 1. The adjusting assembly 3 includes a dragging sleeve and an elastic member 32. The movable sleeve 31 is located in the housing 1 and is slidably connected to the housing 1. The elastic member 32 is disposed between the movable sleeve 31 and the housing 1 and is arranged along the axial direction of the housing 1. The movable sleeve 31 and the elastic member 32 are sleeved on the outer periphery of the locking assembly 2. Wherein, a pressure display part 4 is disposed on the outer periphery of the housing 1, and the pressure display part 4 is configured to correspond to the pressure received by the elastic member 32.

[0033] In this embodiment, the pressure regulating device is used in the test adjustment process of adjusting the pressure of the component to be pressure - regulated. In the embodiments shown in the present disclosure, the pressure adjustment of the chip by the notebook computer cooling module 5 is taken as an example. Therefore, the component to be pressure - regulated specifically refers to the cooling module 5. The cooling module 5 is commonly used to dissipate heat from the CPU or GPU. The CPU and GPU are usually arranged on the motherboard 6. Among them, the locking component 2 can use locking screws. The locking end 21 of the locking component 2 is a threaded section with threads. The locking component 2 is used to lock the cooling module 5 and the motherboard 6 together. When the cooling module 5 and the motherboard 6 are locked, the movable sleeve 31 abuts against the cooling module 5. As the locking continues, the movable sleeve 31 exerts a locking pressure on the cooling module 5. According to Newton's third law, the elastic member 32 simultaneously exerts the same force on the cooling module 5 and the movable sleeve 31. The movable sleeve 31 undergoes displacement along the axial direction of the housing 1. The movable sleeve 31 transfers the force to the elastic member 32, and the elastic member 32 undergoes elastic deformation and is compressed. The pressure provided by the elastic member 32 can be read through the pressure display part 4 on the housing 1. Thus, the locking pressure can be adjusted during the test stage and can be read in real - time, ensuring the accuracy of the pressure and uniformity of the cooling module 5; during the test process, only by repeatedly screwing the locking component 2 to make the pressure regulating device provide different pressures can the accurate design pressure be finally obtained, without the need for multiple proof - of - concept samples, saving the cost and time of proof - of - concept samples and improving production efficiency. The elastic member 32 is specifically a spring. The elastic coefficient of the spring is affected by multiple factors, mainly including the diameter of the spring, the wire diameter of the spring, the material of the spring, and the effective number of turns of the spring, and can be adaptively designed and selected according to actual needs. The elastic member 32 has an initial state and a compressed state. When the elastic member 32 is in the initial state, the movable sleeve 31 is in the initial position. As the pressure on the movable sleeve 31 increases, the movable sleeve 31 undergoes displacement along the axial direction of the housing 1 and is in a pressure - regulating position. At this time, the elastic member 32 is in a compressed state.

[0034] In actual application, first, the heat dissipation module 5 is designed according to theoretical calculations and a sample is made. The actual pressure of the heat dissipation module 5 produced from the sample needs to be greater than the designed pressure for subsequent adjustment. Then, an indentation test is carried out to adjust the pressure uniformity. That is, a test paper is placed between the heat dissipation module 5 produced from the sample and the main board 6, and the heat dissipation module 5 and the main board 6 are locked together using the pressure adjustment device. The pressure provided by the elastic member 32 is read through the pressure display portion 4 on the housing 1. If the pressure does not match the expectation, the position of the movable sleeve 31 can be changed by screwing the locking assembly 2, thereby changing the deformation of the elastic member 32. By changing the elastic force of the elastic member 32, the pressure it provides is modified to achieve the effect of adjusting the pressure and reading it in real time. After the pressure adjustment of the pressure adjustment device is completed, the pressure adjustment device and the heat dissipation module 5 are removed, and it is observed whether the indentation of the test paper meets the requirements. If it does not meet the requirements, the pressure at each locking location is redesigned according to the test results, and the pressure is locked to the designed value again through the pressure adjustment device, and it is observed whether the indentation meets the requirements until the indentation meets the requirements. Then, the pressure at each locking location is designed according to the test results to complete the pressure design of the heat dissipation module 5.

[0035] In an implementable manner, the movable sleeve 31 includes a connecting portion 311 and an abutting portion 312. The connecting portion 311 is configured to be adapted to the inner diameter of the housing 1 so that the movable sleeve 31 can slide axially along the housing 1.

[0036] Specifically, in an implementable manner, the outer diameter of the abutting portion 312 is smaller than the outer diameter of the connecting portion 311.

[0037] In this embodiment, the outer diameter of the abutting portion 312 can be the same as the outer diameter of the connecting portion 311 or smaller than the outer diameter of the connecting portion 311. The connecting portion 311 is configured to be adapted to the inner diameter of the housing 1 to ensure that the movable sleeve 31 can slide stably axially along the housing 1 without wobbling, ensuring the accuracy of the test results. It can be understood that the pressure display portion 4 is for displaying the pressure received by the elastic member 32. Therefore, the display scale can also be provided on the abutting portion 312. Correspondingly, the open end 11 of the housing 1 serves as an indicator, and as the movable sleeve 31 is pressed into the housing 1, the indicating scale changes.

[0038] In an implementable manner, a limiting protrusion 313 is provided on the connecting portion 311. The housing 1 is provided with a guiding groove 13 in the axial direction. The limiting protrusion 313 is located in the guiding groove 13, and the pressure display portion 4 is provided beside the guiding groove 13.

[0039] In this embodiment, the limiting protrusion 313 prevents the movable sleeve 31 from rotating axially around the housing 1, and the limiting protrusion 313 can also play a role in indicating the scale. When the elastic member 32 is in the initial state, the movable sleeve 31 is located at the initial position, and the limiting protrusion 313 indicates an initial scale in the guiding groove 13. As the pressure on the movable sleeve 31 increases, the movable sleeve 31 axially displaces along the housing 1 and is located at a pressure regulating position. At this time, the elastic member 32 is in a compressed state, and the limiting protrusion 313 slides along the guiding groove 13 and indicates a pressure regulating scale.

[0040] In an implementable embodiment, the housing 1 includes opposite open ends 11 and mounting ends 12. The movable sleeve 31 is located at the open end 11, and the locking assembly 2 is connected to the housing 1 through the mounting end 12. The housing 1 is also provided with a mounting groove 14, and the mounting groove 14 communicates with the open end 11 and the guiding groove 13.

[0041] Specifically, in an implementable embodiment, the mounting groove 14 includes a first section 141 and a second section 142. The first section 141 is parallel to the guiding groove 13 and communicates with the open end 11, and the second section 142 is perpendicular to the guiding groove 13 and is used to connect the first section 141 and the guiding groove 13.

[0042] In this embodiment, when the movable sleeve 31 is installed on the housing 1, the limiting protrusion 313 enters from the entrance of the mounting groove 14 at the open end 11 of the housing 1 and slides along the mounting groove 14 until it slides into the guiding groove 13, and the installation is completed. Specifically, the limiting protrusion 313 enters from the first section 141 where the mounting groove 14 communicates with the open end 11, slides along the first section 141 to the connection with the second section 142, and then slides into the guiding groove 13 along the second section 142. It can be understood that the number of guiding grooves 13 can be two, and the two guiding grooves 13 are symmetrically arranged on the housing 1. Correspondingly, the number of limiting protrusions 313 can be one or two. When the number of limiting protrusions 313 is two, the two limiting protrusions 313 are correspondingly arranged with the two guiding grooves 13. At this time, the number and position of the mounting grooves 14 also correspond to the number and position of the limiting protrusions 313.

[0043] In an implementable embodiment, the elastic member 32 includes opposite first and second ends. The first end is abutted and limited by the mounting end 12, and the second end abuts against the connecting portion 311.

[0044] In an implementable embodiment, the locking assembly 2 further includes an operating end 22. The locking end 21 extends into the housing 1 from the mounting end 12 and passes through, and the operating end 22 abuts against the mounting end 12.

[0045] In this embodiment, the mounting end 12 of the housing 1 is in the shape of a groove, and the bottom of the groove has an opening. The operating end 22 of the locking assembly 2 is the end where the nut is located. The locking end 21 extends into the housing 1 through the opening and passes out from the open end 11, and the operating end 22 is sunk in the groove. It can be understood that the operating end 22 can be sunk in the groove, or can be sunk in the groove and fixedly connected to the groove, such as by welding or gluing. When the operating end 22 is sunk in the groove without being fixedly connected to the groove, when adjusting the locking assembly 2, the housing 1 does not rotate or rotates slightly with the locking assembly 2; when the operating end 22 is sunk in the groove and fixedly connected to the groove, when adjusting the locking assembly 2, the housing 1 rotates with the locking assembly 2.

[0046] Referring to Figure 6 As shown, the present disclosure also provides a test system, including a heat dissipation module 5 and a main board 6. The heat dissipation module 5 has a pressure structure 51, and further includes a pressure regulating device as described in any of the above embodiments. The pressure structure 51 and the main board 6 are locked by a locking assembly 2.

[0047] Specifically, in an implementable embodiment, the test system further includes a test strip, and the test strip is disposed between the heat dissipation module 5 and the main board 6.

[0048] In this embodiment, the number of the pressure regulating devices may be one or more. In this embodiment, five pressure regulating devices are taken as an example. During the test, first, the heat dissipation module 5 is designed according to theoretical calculations and a sample is made. The actual pressure of the heat dissipation module 5 made from the sample needs to be greater than the designed pressure for subsequent adjustment. Then, the pressure uniformity is adjusted by indentation testing, that is, a test paper (not shown in the figure) is placed between the heat dissipation module 5 made from the sample and the main board 6. The five pressure regulating devices lock the heat dissipation module 5 and the main board 6 together, and the pressure provided by the elastic member 32 is read through the pressure display portion 4 on the housing 1. If the pressure does not match the expectation, the position of the movable sleeve 31 can be changed by screwing the locking assembly 2, thereby changing the deformation of the elastic member 32. The pressure provided by the elastic member 32 is modified by the change in the elastic force of the elastic member 32 to achieve the effect of adjusting the pressure and reading it in real time. After the pressure adjustment of the pressure regulating device is completed, the pressure regulating device and the heat dissipation module 5 are removed, and it is observed whether the indentation of the test paper meets the requirements. If the requirements are not met, the pressure at each locking location is redesigned according to the test results, and the pressure is locked to the designed value again through the pressure regulating device, and it is observed whether the indentation meets the requirements until the indentation meets the requirements. Then, the pressure at each locking location is designed according to the test results to complete the pressure design of the heat dissipation module 5. Thus, the test system enables the locking pressure to be adjustable during the test stage and can be read in real time, ensuring the accuracy of the pressure and uniformity of the heat dissipation module 5. During the test, only by repeatedly screwing the locking assembly 2 to make the pressure regulating device provide different pressures can the accurate designed pressure be finally obtained, without the need for multiple samplings, saving the sampling cost and time and improving the production efficiency.
