Description

Technical Field

[0001] This invention relates to the field of computer hardware heat dissipation technology, and in particular to an intelligent temperature control and energy-saving optimization device for computer hardware heat dissipation. Background Technology

[0002] During computer operation, hardware devices continuously generate heat. If this heat cannot be dissipated in time, the hardware temperature will rise, affecting the computer's performance and lifespan, and in severe cases, even causing hardware damage. Currently, most common computer hardware cooling devices use fans for forced cooling. However, traditional cooling devices have the following problems: First, cooling fans usually operate at a fixed speed and cannot intelligently adjust according to the actual temperature of the hardware, resulting in high-speed operation even when the hardware temperature is low, leading to energy waste. Second, dust easily accumulates at the ventilation openings of the cooling device. If not cleaned in time, it will block the ventilation channels, reduce the cooling effect, and manual cleaning is not only troublesome but may also damage the hardware.

[0003] To address the aforementioned issues, this invention proposes an intelligent temperature control and energy-saving optimization device for computer hardware heat dissipation. This device enables intelligent temperature control, adjusts the heat dissipation intensity based on the hardware temperature, and features automatic cleaning to ensure the stability of the heat dissipation effect while also contributing to energy conservation. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned technologies. The technical solution adopted by this invention is as follows:

[0005] A smart temperature control and energy-saving optimization device for computer hardware heat dissipation includes a housing. A ventilation hole is provided on one side of the housing. A temperature sensor is located inside the housing. A control module is located inside the housing. A filter structure is located inside the housing and is fitted onto the ventilation hole. A ventilation structure is located inside the housing, including a cleaning structure and a displacement structure. The cleaning structure includes a dust filter cover. One side of the dust filter cover is open and extends through one side of the housing. A second ventilation hole is provided on the side of the dust filter cover away from the housing. A fan module is located on the side of the dust filter cover away from the open side, and the side of the fan module is sealed to one side of the dust filter cover. The dust filter hood has a filter plate 2 inside, which is attached to multiple ventilation holes 2. A roller brush is attached to the side of the filter plate 2 away from the ventilation holes 2. The roller brush is arranged horizontally and parallel, with its two ends respectively close to the two ends of the dust filter hood. One end of the roller brush is rotatably connected to a motor 2. The displacement structure includes a motor 3, which is fixed to the bottom of the inner side of the dust filter hood. A threaded rod is rotatably connected to the top of the motor 3. A threaded tube is threaded onto the body of the threaded rod. A connecting rod is provided on one side of the threaded tube. The end of the connecting rod away from the threaded tube is connected and fixed to the end of the motor 2 away from the roller brush. The housing has an intelligent temperature control and energy-saving optimization system module.

[0006] As a further embodiment of the present invention, the intelligent temperature control and energy-saving optimization system module includes a temperature acquisition module, a central control module, a heat dissipation drive module, and an energy consumption monitoring module, and the modules are connected to each other via a data bus.

[0007] The temperature acquisition module includes multiple miniature temperature sensors, which are respectively attached to the core hardware surfaces of the computer CPU, graphics card, and motherboard chipset. They are used to collect temperature data of each hardware in real time. The sensor sampling frequency is set to 1 time / second, the temperature measurement range is -10℃ to 120℃, and the measurement accuracy is ±0.5℃. The collected temperature data is sent to the central control module in real time via wired transmission.

[0008] The central control module uses an embedded microprocessor with a built-in temperature threshold database and speed regulation algorithm. The temperature threshold database presets the safe temperature range and corresponding speed level for each piece of hardware. After receiving real-time data from the temperature acquisition module, the central control module compares it with the preset threshold, calculates the optimal speed of the cooling fan for each piece of hardware through the speed regulation algorithm, and sends control commands to the cooling drive module.

[0009] The heat dissipation drive module includes multiple independent fan drive circuits, corresponding to the CPU fan, graphics card fan and chassis cooling fan respectively. After receiving the speed command from the central control module, the drive circuit adjusts the output voltage from 12V to 5V to achieve stepless adjustment of the fan speed. At the same time, the drive module has a fault detection function. When the fan speed deviates from the command speed by more than 10%, it sends a fault signal to the central control module.

[0010] The energy consumption monitoring module includes a current sensor and a voltage sensor, which are connected in series in the power supply circuit of the computer power supply and the cooling fan. It collects the operating current and voltage of each fan in real time, and calculates the energy consumption data of a single fan and the entire cooling system using the formula "energy consumption = voltage × current × working time". The energy consumption data is fed back to the central control module in real time. When the total energy consumption of the system exceeds the preset energy-saving threshold, the central control module appropriately reduces the fan speed while ensuring the safety of hardware temperature, thereby optimizing energy consumption.

[0011] As a further aspect of the present invention, the speed regulation algorithm of the central control module adopts a "segmented dynamic adjustment" strategy: when the hardware temperature is lower than the lower limit of the safe range, the corresponding fan is controlled to run at a low speed; when the temperature is within the safe range, it runs at a medium speed; when the temperature is higher than the upper limit of the safe range, it runs at a high speed; at the same time, if the hardware temperature rises by more than 5°C within 10 seconds, a "rapid speed-up" mechanism is triggered, directly increasing the fan speed to 120% of the current level; and the system also includes a user interaction module, which uses an LCD display and buttons to display the real-time temperature of each hardware component, fan speed, and system energy consumption. Users can manually adjust the fan speed mode through the buttons, and in manual mode, the fan speed level can be directly set.

[0012] As a further aspect of the present invention, the intelligent temperature control and energy-saving optimization system for computer hardware heat dissipation is characterized in that the temperature threshold database presets the safe temperature ranges and corresponding speed levels for each hardware component as follows: CPU safe range 35℃~80℃, graphics card safe range 40℃~85℃, low speed 2000~3000 rpm, medium speed 3000~5000 rpm, and high speed 5000~7000 rpm; the preset energy-saving threshold of the energy consumption monitoring module is 10W.

[0013] As a further embodiment of the present invention, the control module is connected to the temperature sensing device and the fan module.

[0014] As a further embodiment of the present invention, a hardware mounting plate is provided inside the housing.

[0015] As a further embodiment of the present invention, the plurality of ventilation holes are arranged in an equidistant array, and are all located near the center of one side of the housing.

[0016] As a further embodiment of the present invention, the filter structure includes a chute and a filter plate. The two chutes are placed parallel to each other, and the sides of the chute are fixedly connected to the inner side of the housing. The sides of the two filter plates are placed in close contact with each other. The filter plates are adapted to the chute and can slide laterally inside the chute. One side of each of the two filter plates is attached to a plurality of ventilation holes. A limiting rod is inserted laterally through the two filter plates near the top. The limiting rod passes parallel through the two filter plates and its two ends are fixedly connected to the two ends inside the housing. A bidirectional threaded rod is threaded laterally through the two filter plates near the bottom. Both ends of the bidirectional threaded rod are threaded through the two filter plates. One end of the bidirectional threaded rod is connected to a motor, and the motor is fixedly connected to the inner side of the housing.

[0017] As a further embodiment of the present invention, the plurality of ventilation holes are distributed in an equidistant array on one side of the dust filter cover.

[0018] As a further embodiment of the present invention, a limiting rod two is vertically and movably inserted on the connecting rod body, and the upper and lower ends of the limiting rod two are respectively connected and fixed to the upper and lower ends inside the dust filter cover.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention incorporates a temperature sensing device and a control module. The temperature sensing device monitors the temperature of the internal hardware in real time and transmits the temperature information to the control module. The control module then controls the fan module's speed based on the temperature information. When the hardware temperature is high, the control module increases the fan module's speed to enhance heat dissipation; when the hardware temperature is low, the control module reduces the fan module's speed to decrease energy consumption, thus achieving intelligent temperature control and energy saving.

[0021] This invention incorporates a filtration structure. The filter plate in the filtration structure filters the air entering the housing through the ventilation hole, preventing dust from entering the housing and contaminating the hardware. Simultaneously, when the fan module blows air into the housing, the motor drives the bidirectional threaded rod to rotate. Under the limiting action of the limiting rod, the two filter plates can move relative to each other within the sliding groove, allowing the ventilation hole to dissipate heat quickly and improving heat dissipation efficiency.

[0022] The ventilation structure of this invention includes a cleaning structure and a displacement structure. Filter plate two can further filter the air entering the dust hood through ventilation hole two, further reducing dust entering the housing. When dust accumulates on filter plate two, motor two drives the roller brush to rotate, while motor three drives the threaded rod to rotate, causing the threaded tube to move on the threaded rod. Through the connecting rod, motor two and the roller brush move together. The roller brush moves laterally while rotating, enabling thorough cleaning of filter plate two, preventing dust from clogging it, ensuring ventilation effect, and thus ensuring the stability of heat dissipation.

[0023] The second limiting rod can limit the movement of the connecting rod, ensuring the stability of the roller brush during movement and improving the cleaning effect.

[0024] Intelligent and precise temperature control: Through multi-point temperature sensors and segmented speed regulation algorithms, targeted temperature control is achieved for different hardware components, avoiding insufficient heat dissipation or excessive power consumption caused by a single speed, and ensuring that the hardware operates within a safe temperature range.

[0025] Significant energy-saving effect: The energy consumption monitoring module provides real-time feedback on energy consumption data, and the central control module dynamically adjusts the fan speed according to the energy consumption threshold, reducing energy consumption in low-load scenarios. Compared with traditional fixed-speed systems, energy consumption can be reduced by 20% to 30%.

[0026] High reliability: The heat dissipation drive module has a fault detection function, which can detect and report fan abnormalities in a timely manner. At the same time, the user interaction module supports manual intervention, improving the flexibility and safety of system use.

[0027] Obviously, based on the above description of the present invention, and according to common technical knowledge and conventional methods in the field, various other modifications, substitutions, or alterations can be made without departing from the basic technical concept of the present invention.

A limiting rod 605 is inserted laterally through the two filter plates 602 near their top positions. The limiting rod 605 moves parallel through the two filter plates 602, and its two ends are respectively connected and fixed to the two ends inside the housing 1. A bidirectional threaded rod 604 is threaded laterally through the two filter plates 602 near their bottom positions. Both ends of the bidirectional threaded rod 604 are threaded through the two filter plates 602. One end of the bidirectional threaded rod 604 is connected to a motor 603, and the motor 603 is connected and fixed to the inside of the housing 1. The interior is equipped with a ventilation structure 7, which includes a cleaning structure and a displacement structure. The cleaning structure includes a dust filter hood 702, one side of which is open and extends through one side of the housing 1. A second ventilation hole 703 extends through the dust filter hood 702 on the side away from the housing 1. A fan module 701 is located on the side of the dust filter hood 702 away from the open end, and its side is sealed to one side of the dust filter hood 702. A second filter plate 704 is located inside the dust filter hood 702, and the second filter plate 704 is attached to multiple second ventilation holes 703. The multiple second ventilation holes 703 are evenly spaced on one side of the dust filter hood 702. A roller brush 711 is attached to the side of the second filter plate 704 away from the second ventilation holes 703. 711 is arranged horizontally and parallel, and the two ends of the roller brush 711 are respectively close to the two ends of the dust cover 702.

The end of the connecting rod 709 away from the threaded tube 708 is connected and fixed to the end of the second motor 705 away from the roller brush 711.

[0042] The housing houses an intelligent temperature control and energy-saving optimization system module, which includes a temperature acquisition module, a central control module, a heat dissipation drive module, and an energy consumption monitoring module. These modules are connected via a data bus. The temperature acquisition module includes multiple miniature temperature sensors, which are attached to the core hardware surfaces of the computer CPU, graphics card, and motherboard chipset to collect temperature data from each hardware component in real time. The sensor sampling frequency is set to 1 time / second, the temperature measurement range is -10℃ to 120℃, and the measurement accuracy is ±0.The collected temperature data (5℃) is transmitted in real-time to the central control module via wired transmission. The central control module employs an embedded microprocessor with a built-in temperature threshold database and speed control algorithm. The temperature threshold database presets the safe temperature range and corresponding speed levels for each piece of hardware. After receiving real-time data from the temperature acquisition module, the central control module compares it with the preset thresholds, calculates the optimal speed for the cooling fans of each piece of hardware using the speed control algorithm, and sends control commands to the cooling drive module. The cooling drive module includes multiple independent fan drive circuits, corresponding to the CPU fan, graphics card fan, and chassis cooling fan, respectively. The drive circuits receive control commands from the central control module. After receiving the speed command from the control module, the output voltage is adjusted from 12V to 5V to achieve stepless adjustment of the fan speed. Simultaneously, the drive module has a fault detection function; when the fan speed deviates from the commanded speed by more than 10%, a fault signal is sent to the central control module. The energy consumption monitoring module includes current and voltage sensors connected in series in the power supply circuit of the computer power supply and the cooling fans. It collects the operating current and voltage of each fan in real time and calculates the energy consumption data of a single fan and the entire cooling system using the formula "Energy Consumption = Voltage × Current × Operating Time". The energy consumption data is fed back to the central control module in real time. When the total system energy consumption exceeds the preset energy-saving threshold... At the same time, the central control module appropriately reduces the fan speed to optimize energy consumption while ensuring hardware temperature safety. The speed regulation algorithm of the central control module adopts a "segmented dynamic adjustment" strategy: when the hardware temperature is below the lower limit of the safe range, the corresponding fan is controlled to run at a low speed; when the temperature is within the safe range, it runs at a medium speed; when the temperature is above the upper limit of the safe range, it runs at a high speed. Simultaneously, if the hardware temperature rises by more than 5°C within 10 seconds, a "rapid speed-up" mechanism is triggered, directly increasing the fan speed to 120% of the current level. The system also includes a user interaction module, using an LCD display and buttons. This intelligent temperature control and energy-saving optimization system for computer hardware cooling displays real-time temperatures, fan speeds, and system energy consumption for each hardware component. Users can manually adjust fan speed modes via buttons, and in manual mode, fan speed levels can be directly set. Its features include a preset safe temperature range and corresponding speed levels for each hardware component in a temperature threshold database: CPU safe range 35℃~80℃, graphics card safe range 40℃~85℃, low speed 2000~3000 RPM, medium speed 3000~5000 RPM, high speed 5000~7000 RPM; the preset energy-saving threshold for the energy consumption monitoring module is 10W.

[0043] Working principle and usage process of this invention:

[0044] In use: When the device is running, the hardware is installed on the hardware mounting plate 2. The temperature sensing device 3 monitors the temperature inside the housing 1 in real time and transmits it to the control module 4. The control module 4 adjusts the speed of the fan module 701 according to the temperature. When the temperature is low, the speed is low to save energy, and when the temperature is high, the speed is high to enhance heat dissipation.

[0045] During ventilation and heat dissipation, outside air enters through ventilation hole 703 of dust filter cover 702. After the filter plate 704 filters the dust, it enters the housing 1 under the action of fan module 701 to exchange with hot air. The hot air is discharged through ventilation hole 5 of housing 1 and filtered again by filter plate 602.

[0046] When dust accumulates on filter plate 704, motor 705 drives the roller brush 711 to rotate, and motor 710 drives the threaded rod 706 to move the threaded tube 708. Through the connecting rod 709, the roller brush 711 is moved to thoroughly clean filter plate 704.

[0047] The operation flow of the intelligent temperature control and energy-saving optimization system module is as follows:

[0048] System startup phase: After the computer is powered on, the temperature acquisition module, central control module, heat dissipation drive module and energy consumption monitoring module start up simultaneously; the temperature acquisition module initializes each sensor and sends initial temperature data to the central control module; the central control module calls the temperature threshold database and starts all cooling fans at low speed by default.

[0049] During normal operation: The temperature acquisition module collects the temperature of each hardware component every second and sends it to the central control module. If the CPU temperature is 50℃, the central control module calculates and sends a "medium speed" command to the CPU fan drive circuit. The drive circuit adjusts the voltage to 8V and controls the fan to run at 4000 RPM. If the graphics card temperature rises to 88℃, a "high speed" command is sent to the graphics card fan, and a rapid speed-up mechanism is triggered, increasing the speed to 6500 RPM within 1 second until the graphics card temperature drops below 80℃, and then returning to medium speed.

[0050] Energy consumption optimization phase: The energy consumption monitoring module collects the energy consumption of each fan in real time. If the total energy consumption of the system reaches 12W and the temperature of each hardware is within the lower limit of the safe range, the central control module sends a "low speed" command to all fans to reduce the total energy consumption to below 8W and achieve energy saving.

[0051] Fault and manual intervention phase: If the CPU fan speed command is 4000 RPM, but the actual speed is only 3500 RPM, the cooling drive module sends a fault signal to the central control module. The central control module displays a "CPU fan abnormal" message on the LCD screen of the user interaction module. The user can press the button to switch to manual mode and set the CPU fan speed to 3800 RPM to ensure temporary cooling needs.
