Description

Technical Field

[0001] This application relates to the field of circuit board technology, and more specifically, to a cooling structure and a cooling device. Background Technology

[0002] Reflow oven fixtures, also commonly known as SMT (Surface Mount Technology) fixtures, are customized trays or frames used to support, hold, and protect circuit boards during the PCB assembly process. During PCB fabrication, reflow oven fixtures effectively protect heat-sensitive components (such as connectors and plastic parts) and completed soldered sections from damage caused by reflow. Furthermore, they prevent bending and deformation of the circuit boards, maintaining their flatness under high-speed transport and high-temperature environments, which is particularly crucial for large, thin boards.

[0003] After passing through the furnace, the reflow fixture has a high temperature. Currently, natural air cooling or water cooling is used to cool the fixture. However, natural air cooling is slow and not suitable for high-efficiency production; water cooling systems are relatively complex, requiring not only cooling pipe design but also water pumps, radiators, and coolant storage devices, resulting in higher equipment costs. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of the prior art by providing a cooling structure and a cooling device to solve the problems of slow cooling speed of natural air cooling for furnace fixtures and complex structure of water cooling systems.

The gas flows along the surface of the furnace fixture to the surrounding area, and then through the first and second exhaust components positioned in the path of gas flow, the gas is discharged outside the chamber. Through the synergistic effect of the first and second chambers, the cold air outside the chamber is circulated in a directional manner with the furnace fixture by the first blower and the first exhaust component, and the second blower and the second exhaust component.

[0020] One aspect of the embodiments of this application, such as Figure 1 As shown, a cooling structure 100 is provided, including a housing 110 having a chamber 120. A support member 130 is disposed in the chamber 120, dividing the chamber 120 into a first chamber 121 and a second chamber 122. A first blower 140 and a first exhaust member 150 communicating with the outside of the housing 110 are respectively disposed on the top wall and side wall of the first chamber 121. The first exhaust member 150 is used to exhaust the gas guided by the first blower 140 to the surface of the support member 130. A second blower 160 and a second exhaust member 170 communicating with the outside of the housing 110 are respectively disposed on the bottom wall and side wall of the second chamber 122. The second exhaust member 170 is used to exhaust the gas guided by the second blower 160 to the surface of the support member 130.

[0021] Specifically, such as Figure 1As shown, the cooling structure 100 includes a housing 110, which has a chamber 120. A support member 130 is disposed within the chamber 120, and the support member 130 is used to support the furnace fixture. The support member 130 divides the chamber 120 into a first chamber 121 and a second chamber 122. It should be noted that the support member 130 divides the chamber 120 into an upper chamber and a lower chamber; for example, the first chamber 121 is the upper chamber and the second chamber 122 is the lower chamber. A first air blowing member 140 communicating with the outside of the housing 110 is disposed on the top wall of the first chamber 121 (that is, the top wall of the housing 110), and a first exhaust member 150 communicating with the outside of the housing 110 is disposed on the side wall of the first chamber 121. A second blower 160 communicating with the outside of the housing 110 is provided on the bottom wall of the second chamber 122 (that is, the bottom wall of the housing 110), and a second exhauster 170 communicating with the outside of the housing 110 is provided on the side wall of the second chamber 122.

[0022] When cooling of the reflow fixture is required, the fixture is placed on the support 130. For example, the side of the fixture closest to the first air blower 140 is the front, and the side closest to the second air blower 160 is the back. Because the surface temperature of the reflow fixture is high, heat is transferred to the surrounding air through heat transfer, causing the air temperature to rise and become hot air. This is achieved by turning on the first air blower 140. Figure 1 As indicated by arrow A, the first blower 140 drives the cold air outside the housing 110 to blow towards the front of the furnace fixture. Under the action of the cold air, the hot air surrounding the furnace fixture is carried away. Simultaneously, the first blower 140 continues to replenish the furnace fixture with new cold air, which comes into contact with the front of the furnace fixture and becomes hot air, which is then carried away by subsequent cold air. Through this cyclical action, the temperature of the furnace fixture is lowered. The first exhaust fan 150 is activated simultaneously with the first blower 140. The air inlet of the first exhaust fan 150 is located inside the first chamber 121, and the air outlet is located outside the first chamber 121. Figure 1 As indicated by the arrow at point B, the air inlet of the first exhaust fan 150 draws away the hot air blown away by the first blower 140 and discharges it to the outside of the first chamber 121 through the air outlet. Through the combined action of the first blower 140 and the first exhaust fan 150, the temperature of the furnace fixture decreases rapidly. By opening the second blower 160, as... Figure 1 As indicated by the arrow at point C, the second blower 160 drives the cold air outside the drive housing 110 to blow towards the back of the furnace fixture. Under the action of the cold air, the hot air around the furnace fixture is carried away, such as... Figure 1As indicated by the arrow at point D, hot air is exhausted to the outside of the second chamber 122 by opening the second exhaust fan 170. The reason why the second blower 160 and the second exhaust fan 170 reduce the temperature of the reflow fixture is the same as that of the first blower 140 and the first exhaust fan 150, and will not be repeated here. Gas is blown into the reflow fixture by the first blower 140, and after heat exchange with the reflow fixture, the gas is exhausted to the outside of the first chamber 121 by the first exhaust fan 150; gas is blown into the reflow fixture by the second blower 160, and after heat exchange with the reflow fixture, the gas is exhausted to the outside of the second chamber 122 by the second exhaust fan 170. Compared with the prior art, which cools the reflow fixture by lowering the temperature in the sealed chamber and then cooling it through heat transfer, this application is for cooling small high-temperature workpieces such as reflow fixtures by using the first blower 140 and the second blower 160 to blow gas simultaneously to the front and back of the reflow fixture, respectively. After passing through the furnace fixture surface, the air flows outwards along the surface of the furnace fixture. Then, through the first exhaust fan 150 and the second exhaust fan 170 positioned in the path of the gas flow direction, the gas is discharged outside the chamber 120. Through the synergistic effect of the first chamber 121 and the second chamber 122, the cold air outside the chamber 120 is directionally circulated with the furnace fixture by the first blower 140 and the first exhaust fan 150, the second blower 160 and the second exhaust fan 170. This directional circulation ensures efficient heat exchange, accelerates the cooling rate of the furnace fixture, achieves precise cooling of the furnace fixture, and has a simpler structure and lower cost compared to a water cooling system.

[0023] In some embodiments, the first blowing element 140 and the second blowing element 160 can be a fan or a blower, and there is no limitation on this.

[0024] In some embodiments, the first exhaust component 150 and the second exhaust component 170 can be centrifugal fans or axial fans, and no limitation is made here.

[0025] Optionally, such as Figure 1 As shown, the first exhaust component 150 is disposed on one side surface of the first chamber 121 near the support component 130; the second exhaust component 170 is disposed on one side surface of the second chamber 122 near the support component 130.

[0026] Specifically, the first exhaust fan 150 is disposed on the side wall of the first chamber 121 and close to the support member 130. When the first blower 140 drives the cold air outside the housing 110 to blow towards the front of the furnace fixture and carries away the hot air around the furnace fixture, because the air pressure of the cold air blown out by the first blower 140 is greater than the air pressure of the hot air around the furnace fixture, the cold air blown towards the furnace fixture will come into contact with the furnace fixture and carry away the hot air around the furnace fixture and continue to flow along the surface of the furnace fixture. By placing the first exhaust fan 150 close to the support member 130, that is, close to the furnace fixture, the air inlet of the first exhaust fan 150 is set in the direction of gas flow, and then the air is discharged to the outside of the first chamber 121 through the air outlet of the first exhaust fan 150. The second exhaust fan 170 is also disposed on the side wall of the second chamber 122 and close to the support member 130. The process by which the second exhaust fan 170 discharges gas to the outside of the second chamber 122 is the same as described above, and will not be repeated here. By distributing the first exhaust fan 150 and the second exhaust fan 170 close to the support member 130, the hot air around the furnace fixture is prevented from stagnating in the chamber 120, which facilitates the rapid discharge of the hot air around the furnace fixture to the outside of the chamber 120 and accelerates the cooling rate of the furnace fixture.

[0027] Optionally, such as Figure 1 As shown, the bearing member 130 is a mesh structure formed by the fixed connection of multiple rods.

[0028] Specifically, the support member 130 has a mesh structure. By placing the reflow fixture on the support member 130, the reflow fixture, which was originally in contact with the upper surface of the support member 130, is now in direct contact with the air, increasing the heat dissipation area of ​​the reflow fixture. The second blower 160 drives the cold air outside the housing 110 to blow towards the back of the reflow fixture. Under the action of the cold air, the hot air around the back of the reflow fixture is carried away. By opening the second exhaust member 170, the hot air is discharged to the outside of the second chamber 122, accelerating the heat dissipation rate of the reflow fixture.

[0029] Optionally, such as Figure 1 As shown, the carrier 130 is fixedly installed in the middle position or near the middle position of the chamber 120.

[0030] Specifically, the furnace fixture is positioned in the middle or near the middle of the chamber 120. This allows the cold air blown by the first blower 140 and the second blower 160 to reach the furnace fixture simultaneously. The air that has accumulated in the furnace fixture and undergone heat exchange will then flow rapidly outwards along the surface of the furnace fixture. By positioning the first exhaust fan 150 and the second exhaust fan 170 in the direction of airflow, the rate at which hot air is discharged from the chamber 120 is accelerated, thereby speeding up the cooling rate of the furnace fixture.

[0031] In some embodiments, the carrier 130 and the chamber 120 can be fixedly connected by threaded connection, snap-fit ​​connection or welding, and no limitation is made here. Optionally, the cooling structure 100 includes a slide rail and a positioning member. The slide rail is disposed on the side wall of the housing 110 and extends vertically. The support member 130 is slidably connected to the slide rail, and the positioning member is used to restrict the support member 130 to a preset position on the slide rail.

[0032] Specifically, the cooling structure 100 includes a slide rail and a positioning element. The slide rail is disposed inside the side wall of the housing 110 and extends vertically, that is, along the axial direction of the reflow fixture. A support member 130 is slidably connected to the slide rail, allowing the support member 130 to be positioned at different locations within the chamber 120. Once the support member 130 has slid to a preset position, the positioning element fixes the support member 130 to the slide rail. The slide rail and positioning element allow the support member 130 to be positioned at different heights within the chamber 120. This facilitates the support member 130 in supporting reflow fixtures of different specifications and also allows adjustment of the distance between the reflow fixture and the first and second air blowers 140 and 160.

[0033] In some implementations, the slide rail can be mounted on the column connecting the adjacent side walls or the column can be configured as the slide rail; no limitation is made here.

[0034] In some implementations, the positioning element can be a screw, a pin, or a limiting block, and there is no specific limitation.

[0035] Optionally, such as Figure 1 As shown, the cooling structure 100 includes a plurality of first air blowers 140, a plurality of first air exhausters 150, a plurality of second air blowers 160, and a plurality of second air exhausters 170. Specifically, by setting up multiple first air blowing components 140, multiple first air extraction components 150, multiple second air blowing components 160 and multiple second air extraction components 170, the gas exchange rate around the furnace fixture can be accelerated, and the cooling rate of the furnace fixture can be accelerated.

[0036] In some implementations, the aforementioned plurality can be two or more, such as three, four, five or six, and is not limited here.

[0037] Optionally, such as Figures 1 to 3 As shown, multiple first blowers 140, multiple first exhausters 150, multiple second blowers 160 and multiple second exhausters 170 are all provided with air guide hoods, and the air inlets of the air guide hoods are funnel-shaped to guide the flow of gas.

[0038] Specifically, such as Figure 2As shown, by setting the air guide shrouds of the multiple first air blowers 140 and the multiple second air blowers 160 in a trumpet shape, specifically, the air inlets of the air guide shrouds are set in a trumpet shape. The trumpet-shaped air inlets can provide a smooth and narrowed flow path for the cold air, guiding the cold air smoothly and accelerating it towards the furnace fixture via the fan; at the same time, the trumpet-shaped air inlets increase the air intake area of ​​the cold air, thereby increasing the air intake flow of the multiple first air blowers 140 and the multiple second air blowers 160. Figure 3 As shown, the air guide hoods of the multiple first exhaust components 150 and the multiple second exhaust components 170 are configured as trumpets. Specifically, the air inlets of the air guide hoods are configured as trumpets. The trumpet-shaped air inlets increase the exhaust area and exhaust volume, which can quickly exhaust the hot air that has undergone heat exchange in the furnace fixture to the outside of the chamber 120.

[0039] In some embodiments, the plurality of first air blowing elements 140 and the plurality of second air blowing elements 160 are all oscillating fans.

[0040] Optionally, such as Figure 1 As shown, the housing 110 has an opening 111 on one side between the top wall and the bottom wall. An opening and closing door 180 is provided at the opening 111. The opening and closing door 180 has a through opening 181. The first chamber 121 and the second chamber 122 are respectively connected to the outside of the housing 110 through the through opening 181. The first exhaust component 150 and the second exhaust component 170 are respectively located on the two side walls adjacent to the opening and closing door 180. Specifically, an opening 111 is provided on the housing 110, located on one side between the top and bottom walls. An opening / closing door 180 is provided at the opening 111, allowing the furnace fixture to be placed on the support member 130 inside the housing 110 by opening and closing the door 180. The opening / closing door 180 has a through-hole 181, connecting the first chamber 121 and the second chamber 122 to the outside of the housing 110. The through-hole 181 allows cold air from outside the housing 110 to enter the chamber 120, and also allows hot air from inside the chamber 120 to dissipate to the outside, thus accelerating the flow rate of gas around the furnace fixture and increasing the cooling rate of the furnace fixture. A first exhaust fan 150 and a second exhaust fan 170 are provided on the two side walls adjacent to the opening / closing door 180.

[0041] Optionally, such as Figure 1 As shown, the cooling structure 100 also includes a walking assembly 190, which is located at the bottom of the housing 110 and rotatably connected to the housing 110.

[0042] Specifically, the walking component 190 facilitates the movement of the housing 110, so that the furnace fixture can be directly placed on the support frame for cooling after being taken out of the hot furnace, avoiding the cumbersome operation of transferring the furnace fixture.

[0043] In some embodiments, the housing 110 is a square housing 110, and the walking assembly 190 can be disposed at the four corners of the bottom of the housing 110; the frame of the housing 110 is made of aluminum alloy, and the top wall, bottom wall and side wall of the housing 110 are glass limiting reinforcement plates.

[0044] In some implementations, the walking component 190 may be a caster wheel or a brake wheel, and there is no limitation on this.

[0045] In another aspect of this application, a cooling device is provided, including the cooling structure 100 described above and a furnace fixture, wherein the furnace fixture is fixedly mounted on the support member 130 of the cooling structure 100.

[0046] Specifically, the cooling device includes a cooling structure 100 and a furnace fixture. The furnace fixture is fixedly mounted on the support member 130. Gas is blown onto the furnace fixture by the first blower 140. After heat exchange with the furnace fixture, the gas is discharged to the outside of the first chamber 121 by the first exhaust member 150. Gas is blown onto the furnace fixture by the second blower 160. After heat exchange with the furnace fixture, the gas is discharged to the outside of the second chamber 122 by the second exhaust member 170. This accelerates the cooling rate of the furnace fixture and has a simpler structure and lower cost compared to a water cooling system.

[0047] In some embodiments, the connection between the reflow fixture and the carrier 130 can be a snap-fit ​​connection, a magnetic connection, or a hook and loop connection, and there is no specific limitation.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
