Description

Technical Field

[0001] The utility model relates to the field of heat dissipation of electromechanical equipment, in particular to a heat dissipation mechanism for electromechanical equipment. Background Art

[0002] The heat dissipation mechanism of electromechanical equipment generally refers to a series of components designed to maintain the internal temperature of the equipment within a normal range. The main purpose of these heat dissipation mechanisms is to effectively dissipate the heat generated within the equipment to the external environment to prevent overheating and the resulting performance degradation, damage, or safety hazards. The specific design of the heat dissipation mechanism varies depending on the type, size, operating conditions, and heat dissipation requirements of the electromechanical equipment. Common heat dissipation mechanisms include heat sinks, fans, heat pipes, and liquid cooling systems.

[0003] A Chinese patent with publication number CN221010587U discloses a rapid heat dissipation mechanism for electromechanical equipment, including a circulating pump, which is arranged on one side of the radiator body, and has a fixed connection between its liquid inlet and outlet. The circulating pump draws the coolant into a first hose, and due to contact with the heating element, it can take away part of the heat energy, and then flows back to the first hose through a third hose, and finally returns to the circular square tube through a reflux port. A micro fan generates wind force, accelerates air flow, speeds up the heat dissipation of the heat dissipation aluminum plate, and ensures the cooling effect of the coolant. By setting multiple, multiple heating elements can be cooled and cooled at the same time. Compared with the existing heat dissipation structure, the installation method is simpler.

[0004] During the heat dissipation process of the rapid heat dissipation mechanism of the electromechanical equipment of the above-mentioned patent, the coolant needs to flow continuously during the cooling process of the electromechanical equipment. The continuous flow can only reduce the temperature at the main body of the radiator. The coolant is not used alternately, and a part of the coolant cannot be cooled for a long time, so that the coolant is always in a high temperature state, resulting in poor heat dissipation effect of the heat dissipation mechanism, which cannot meet the long-term cooling needs of the electromechanical equipment. Summary of the Invention

[0005] The purpose of the present utility model is to provide a heat dissipation mechanism for electromechanical equipment. Through the buffering of the first buffer barrel and the second buffer barrel and the start and stop of the first electric valve and the second electric valve, the transmitted coolant can be replaced, so that part of the coolant is retained in one of the heat dissipation frames and dissipated, while the other part of the coolant is transmitted in the heat dissipation frame, solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a heat dissipation mechanism for electromechanical equipment, comprising a heat dissipation seat, a pump for extracting coolant is provided on one side of the heat dissipation seat, heat dissipation frames are mirror-imaged at the front and rear ends of the upper end of the heat dissipation seat, thermoelectric cooling fins are attached to the front and rear ends of the two heat dissipation frames, a second buffer barrel is provided on one side between the two heat dissipation frames, a first buffer barrel is provided on the other side between the two heat dissipation frames, a second electric valve is provided on the side of the first buffer barrel and the second buffer barrel facing one of the heat dissipation frames, and a first electric valve is provided on the side of the first buffer barrel and the second buffer barrel facing the other heat dissipation frame.

[0007] Preferably, a portion of coolant for transmission is reserved inside the second buffer barrel and the first buffer barrel.

[0008] Preferably, a timing sensor is provided between the two first electric valves and the two second electric valves, and the timing sensor is electrically connected to the first electric valve and the second electric valve respectively.

[0009] Preferably, the low-temperature side of the thermoelectric cooling plate faces the heat dissipation frame.

[0010] Preferably, second heat dissipation frames are recessed on both sides of the heat dissipation frame, a recessed first heat dissipation frame is provided between the two second heat dissipation frames, and heat sinks are attached to both sides of the first heat dissipation frame and the second heat dissipation frame.

[0011] Preferably, fan blades are provided on one side of the exterior of the heat dissipation frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model provides a first buffer barrel and a second buffer barrel for buffering on both sides of the heat dissipation frame. While the first buffer barrel and the second buffer barrel are used for buffering, the first electric valve and the second electric valve are opened and closed at a lower level. The alternating opening and closing can directly adjust the flow direction of the coolant, so that the coolant flows toward the heat dissipation frame, and also the coolant in one of the heat dissipation frames flows toward the heat dissipation seat. During the process of one heat dissipation frame flowing toward the heat dissipation seat, the coolant in the other heat dissipation frame can be stationary for a long time and the temperature can be efficiently reduced. The coolant in the two heat dissipation frames is used alternately for transmission, heat dissipation and cooling. The alternating use can dissipate heat and cool down the electromechanical equipment for a long time, thereby preventing the flowing coolant from being unable to dissipate heat and being in a high temperature state.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to solve the problem that the cooling liquid of the existing rapid heat dissipation mechanism of electromechanical equipment needs to flow continuously during the cooling process of the electromechanical equipment, and the continuous flow can only reduce the temperature at the main body of the radiator, the cooling liquid is not alternately used, and a part of the cooling liquid cannot be cooled for a long time, so that the cooling liquid is always in a high temperature state, resulting in poor heat dissipation effect of the heat dissipation mechanism and inability to meet the long-term cooling needs of the electromechanical equipment, this embodiment provides the following technical solutions:

[0021] A heat dissipation mechanism for electromechanical equipment includes a heat dissipation seat 2, a pump 4 for extracting coolant is provided on one side of the heat dissipation seat 2, such as Figure 1 , the cooling liquid is extracted by the pump 4 and passes through the heat sink 2 to take away the heat absorbed inside the heat sink 2, thereby achieving heat dissipation at the fitting position of the heat sink 2;

[0022] In this embodiment, the front and rear ends of the upper end of the heat sink 2 are mirror-imaged with heat sink frames 1, and the front and rear ends of the two heat sink frames 1 are attached with thermoelectric cooling sheets 7, with the low-temperature side of the thermoelectric cooling sheets 7 facing the heat sink frame 1. Figure 4 As shown, the coolant inside the heat dissipation frame 1 can be cooled by the thermoelectric cooling sheet 7, actively reducing the coolant stored inside the heat dissipation frame 1;

[0023] In this embodiment, the second heat dissipation frames 12 are recessed on both sides of the interior of the heat dissipation frame 1, and a recessed first heat dissipation frame 11 is provided between the two second heat dissipation frames 12. Figure 4 As shown, heat sinks 13 are attached to both sides of the first heat dissipation frame 11 and the second heat dissipation frame 12. The attachment of the heat sinks 13 allows the temperature inside the heat dissipation frame 1 to be transferred to the heat sinks 13. The heat sinks 13 increase the contact area between heat and gas, and the heat dissipation area of ​​the heat dissipation frame 1 can be further increased.

[0024] In this embodiment, if Figure 1 、 Figure 2 and Figure 4 As shown, a fan blade 8 is provided on one side of the exterior of the heat dissipation frame 1. The rotation of the fan blade 8 can extract external air, causing the air to flow toward the interior of the first heat dissipation frame 11 and the second heat dissipation frame 12. The air flowing inside the first heat dissipation frame 11 and the second heat dissipation frame 12 can contact the heat sink 13 and cool down.

[0025] In this embodiment, a second buffer barrel 10 is provided on one side between the two heat dissipation frames 1, and a first buffer barrel 3 is provided on the other side between the two heat dissipation frames 1. Figure 1 and Figure 3 As shown, the coolant extracted and transferred by the pump 4 is buffered by the first buffer barrel 3 and the second buffer barrel 10 when the transfer direction is adjusted. A portion of coolant for transfer is reserved inside the second buffer barrel 10 and the first buffer barrel 3. When the coolant flow direction is adjusted, the liquid inside the second buffer barrel 10 and the first buffer barrel 3 is temporarily used for transfer, so that the coolant is transferred stably and smoothly.

[0026] In this embodiment, the first buffer barrel 3 and the second buffer barrel 10 are both provided with a second electric valve 14 on one side facing one of the heat dissipation frames 1, and the first buffer barrel 3 and the second buffer barrel 10 are both provided with a first electric valve 5 on the other side facing the other heat dissipation frame 1. Figure 1 and Figure 2 As shown, by uniformly starting and closing the two second electric valves 14 and the two first electric valves 5, the flow direction of the coolant can be adjusted so that a portion of the coolant is retained in the heat dissipation frame 1 and cooled;

[0027] In this embodiment, a timing sensor 6 is provided between the two first electric valves 5 and the two second electric valves 14. Figure 1 and Figure 2 As shown, the timing sensor 6 is electrically connected to the first electric valve 5 and the second electric valve 14 respectively. The timing sensor 6 can provide a start signal or a close signal to the two first electric valves 5 and the two second electric valves 14 according to the set time.

[0028] Working principle: When the device is used and the electromechanical equipment is cooled, the bolts are passed through the heat sink 2 and embedded in the heat sink position to complete the fitting, and the pump 4 is started. The pump 4 first extracts the second buffer barrel 10, and the liquid inside the second buffer barrel 10 passes through the heat sink 2 after extraction and absorbs the heat at the fitting position, absorbs heat and cools down, and the heat extracted by the pump 4 is transmitted to the inside of the first buffer barrel 3, the first electric valve 5 is opened, and the second electric valve 14 is closed. The coolant inside the first buffer barrel 3 passes through the first electric valve 5 and is transmitted to the corresponding connected heat sink frame 1, and the liquid inside the heat sink frame 1 is then transmitted to the inside of the second buffer barrel 10 to realize circulation, the timing sensor 6 closes the first electric valve 5 at a time, and the timing sensor 6 opens the second electric valve 14 at a time. When the first electric valve 5 and the second electric valve 14 are adjusted, the second buffer barrel 10 The internal liquid is continuously extracted, and the remaining cavity inside the first buffer barrel 3 can provide continuous transmission of the extracted coolant. After the first electric valve 5 and the second electric valve 14 are opened after adjustment, the excess liquid in the first buffer barrel 3 will be replenished to the inside of the second buffer barrel 10 due to its own weight, and the state between the first buffer barrel 3 and the second buffer barrel 10 will be restored. After adjustment, the coolant extracted by the pump 4 will be transmitted through the second electric valve 14, and the heat dissipation frame 1 connected to the first electric valve 5 will be in a sealed state. Active cooling is performed through the thermoelectric cooling fins 7 at both ends of the outside of the heat dissipation frame 1, and the activation of the fan blades 8 can actively blow the heat transferred by the heat sink 13, actively cooling the heat inside the heat dissipation frame 1. After waiting for the time set by the timing sensor 6, the two heat dissipation frames 1 exchange the liquid transmission state and the static heat dissipation state, and this cycle is repeated.
