[0001] The invention relates to the technical field of cooling vehicle-mounted equipment, and in particular to non-interference liquid cooling equipment for vehicle-mounted electronic equipment. Background Art

[0002] With the development of driving technology, the requirements for electronic equipment in vehicle-mounted equipment applications are becoming higher and higher. As the power consumption of the vehicle-mounted core computing unit continues to increase, and the installation location of the vehicle-mounted core computing unit is no longer limited to the interior of the vehicle cab, the vehicle-mounted core computing unit is required to have high heat dissipation efficiency and dust and water resistance.

[0003] At present, electronic devices in vehicle-mounted equipment applications generally adopt liquid cooling for heat dissipation, but the liquid cooling method of electronic devices in vehicle-mounted equipment applications is relatively limited.

Therefore, the present invention can adjust the degree of heat dissipation according to the heat dissipation amount, and achieve a balance between efficient heat dissipation and low power consumption.

Three pressurizing mechanisms 4 and a pressurizing cylinder 5 are arranged inside the shell 1, and a piston 7 for pressurizing by the pressurizing mechanism 4 is arranged inside the pressurizing cylinder 5.

Specifically, the liquid inlet of the pressurizing cylinder 5 is connected to the liquid cooling mechanism 3 through a unidirectional first conduit 8, and the liquid outlet of the pressurizing cylinder 5 is connected to the flow channel pipe 10 through a unidirectional second conduit 9. The flow channel pipe 10 is spirally wound around the outer surface of the electronic equipment body 2 and refluxes to the liquid cooling mechanism 3 through a reflux pipe 11.

[0021] The above structure, through the design of the pressurizing mechanism 4 and the pressurizing cylinder 5, enables the coolant in the liquid cooling mechanism 3 to be fully pressurized inside the pressurizing cylinder 5, thereby increasing the flow rate of the coolant and further improving the heat dissipation efficiency; at the same time, the liquid inlet and the liquid outlet of the pressurizing cylinder 5 are respectively connected to the liquid cooling mechanism 3 and the flow channel tube 10 through the unidirectional first conduit 8 and the second conduit 9, ensuring the unidirectional flow of the coolant in the system, avoiding the backflow and mixing of the coolant in the system, and ensuring the consistency and stability of the heat dissipation effect.

[0022] The front of the housing 1 is provided with an electric control component 12 for controlling the adaptive flow of the cooling liquid inside the liquid cooling mechanism 3. The electric control component 12 is temperature controlled. The higher the temperature, the greater the flow of the liquid cooling mechanism 3. Specifically, the electric control component 12 includes a 220V AC power supply, a control switch, three parallel thermistors 13, and an immutable capacitor C. The thermistor 13 is a negative temperature coefficient thermistor device. The three thermistors 13 are in contact with the heating ports of the three electronic equipment bodies 2.

Specifically, the liquid inlet of the pressurizing cylinder 5 is connected to the liquid cooling mechanism 3 through a unidirectional first conduit 8, and the liquid outlet of the pressurizing cylinder 5 is connected to the flow tube 10 through a unidirectional second conduit 9. The flow tube 10 is spirally wound around the outer surface of the electronic device body 2 and refluxes to the liquid cooling mechanism 3 through the reflux pipe 11.

[0028] The above structure, through the design of the pressurizing mechanism 4 and the pressurizing cylinder 5, enables the coolant in the liquid cooling mechanism 3 to be fully pressurized inside the pressurizing cylinder 5, thereby increasing the flow rate of the coolant and further improving the heat dissipation efficiency; at the same time, the liquid inlet and the liquid outlet of the pressurizing cylinder 5 are respectively connected to the liquid cooling mechanism 3 and the flow channel tube 10 through the unidirectional first conduit 8 and the second conduit 9, ensuring the unidirectional flow of the coolant in the system, avoiding the backflow and mixing of the coolant in the system, and ensuring the consistency and stability of the heat dissipation effect.

[0029] The front of the housing 1 is provided with an electric control component 12 for controlling the adaptive flow of the cooling liquid inside the liquid cooling mechanism 3. The electric control component 12 is temperature controlled. The higher the temperature, the greater the flow of the liquid cooling mechanism 3. Specifically, the electric control component 12 includes an AC power supply, a control switch, three parallel thermistors 13, and a capacitor. The thermistor 13 is a negative temperature coefficient thermistor device. The three thermistors 13 are in contact with the heating ports of the three electronic equipment bodies 2. The capacitor provides power support for the pressurizing mechanism 4. Secondly, the pressurizing mechanism 4 includes a 1, a fixed frame 41 is provided on the inner wall of the upper part of the fixed frame 41, a driving disk 42 connected to the power supply end of the capacitor is arranged inside the fixed frame 41, the rotation speed of the driving disk 42 is proportional to the capacity of the capacitor, the front side of the driving disk 42 is rotatably connected to the outside with a connecting rod 43, the bottom of the connecting rod 43 is rotatably connected to a slide plate 44, the bottom of the slide plate 44 is fixedly connected to a guide rod 45, the bottom of the guide rod 45 slides through the inside of the pressurizing cylinder 5 and is fixedly connected to the piston 7, the driving disk 42 rotates, and under the action of the connecting rod 43, the slide plate 44, the guide rod 45 and the piston 7 are driven to reciprocate up and down.

[0030] The above structure, through the design of the electronic control component 12, enables the coolant inside the liquid cooling mechanism 3 to adapt and flow according to the heat generation of the electronic device body 2. When the heat generation of the electronic device body 2 increases, the resistance value of the thermistor 13 decreases, and the discharge power of the capacitor increases, thereby increasing the rotation speed of the drive disk 42, that is, accelerating the reciprocating speed of the piston 7, thereby increasing the flow rate of the coolant inside the liquid cooling mechanism 3, thereby improving the heat dissipation efficiency; similarly, when the heat generation of the electronic device body 2 decreases, the resistance value of the thermistor 13 increases, and the discharge power of the capacitor decreases, thereby reducing the rotation speed of the drive disk 42, that is, reducing the reciprocating speed of the piston 7, thereby reducing the flow rate of the coolant inside the liquid cooling mechanism 3, thereby avoiding unnecessary power consumption. Therefore, the present invention can adjust the degree of heat dissipation according to the heat dissipation amount, and achieve a balance between efficient heat dissipation and low power consumption.

[0031] The power connection ends of the three electronic equipment bodies 2 all extend out of the housing 1 and are connected to a wiring mechanism 14 , which is used to connect to an external connector.

[0032] Example 3: Combination Figure 7 and Figure 8 On the basis of the second embodiment, the power connection ends of the three electronic equipment bodies 2 all extend out of the housing 1 and are connected to a wiring mechanism 14, which is used to connect an external connector. Specifically, the wiring mechanism 14 includes a connector 141, and a clamping sleeve 142 is fixedly sleeved on the outer wall of the connector 141. A hollow cylinder 143 is penetrated through the outer side of the clamping sleeve 142. A first rack 144 is inserted into the outer surface of the hollow cylinder 143. The bottom side wall of the first rack 144 is meshedly connected to a gear 145. The gear 145 is connected to the outer side wall of the first rack 144. The side wall of 45 is meshedly connected with a second rack 146, the upper end of the second rack 146 is fixedly connected with a first spring 148, the upper end of the first spring 148 is fixedly connected to the upper inner wall of the hollow cylinder 143, the bottom of the second rack 146 is fixedly connected with a clamping head 147 for clamping with an external joint, and secondly, a cavity 149 is provided at the bottom of the clamping head 147, the inner wall of the cavity 149 is fixedly connected with a second spring 1491, and the outer end of the second spring 1491 is fixedly connected with an extrusion plate 1492.

[0034] Working principle: The vehicle-mounted electronic equipment does not interfere with the liquid cooling equipment. When the heat generated by one of the electronic equipment bodies 2 increases, the resistance value of the corresponding thermistor 13 decreases, and the discharge power of the capacitor increases, thereby increasing the rotation speed of the drive disk 42. The drive disk 42 rotates, and under the action of the connecting rod 43, the slide plate 44, the guide rod 45 and the piston 7 are driven to move up and down, that is, the reciprocating speed of the piston 7 is accelerated, thereby increasing the coolant flow inside the liquid cooling mechanism 3, thereby improving the heat dissipation efficiency; When the heat generated by the electronic device body 2 decreases, the resistance value of the corresponding thermistor 13 increases, and the discharge power of the capacitor decreases, thereby reducing the rotation speed of the drive disk 42, that is, reducing the reciprocating speed of the piston 7, and thereby reducing the flow rate of the coolant inside the liquid cooling mechanism 3, thereby avoiding unnecessary power consumption, that is, being able to adjust the heat dissipation degree according to the heat dissipation amount, and achieving a balance between efficient heat dissipation and low power consumption; Secondly, when the connector 141 needs to be connected to the external connector, the card block on the outer surface of the external connector is inserted into the cavity 149, which will drive the extrusion plate 1492 to retract, and under the action of the first rack 144, the second rack 146 and the first spring 148, it is clamped into the clamp head 147 to achieve docking; When it is necessary to remove it, the first rack 144 is pressed, and the external connector can be ejected under the action of the second spring 1491. This design not only ensures a stable connection between the external connector and the connector 141, but also prevents dust and moisture from entering the electronic device body 2, thereby improving the dustproof and waterproof performance of the device.
