Abstract
Description
Technical Field
[0001] This utility model relates to the field of laptop heat sinks, and particularly to laptop air conditioner heat sinks. Background Technology
[0002] Laptops generate a significant amount of heat during use, especially in high temperatures, necessitating the use of a laptop cooler to cool the laptop's casing. Traditional laptop cooling typically employs a tilted stand with a fan inside, blowing air onto the laptop's casing to cool it. However, this approach has a drawback: in high temperatures, the airflow directed at the laptop casing is relatively hot, resulting in limited cooling effectiveness.
[0003] Patent CN 209728665U discloses a laptop cooler, specifically a bottom shell with a sloping surface. The sloping surface has a heat-conducting panel for supporting the laptop and mounting holes. A semiconductor cooling chip is disposed in the mounting holes. The bottom shell contains a metal heat sink and a fan for blowing air onto the metal heat sink. The semiconductor cooling chip is in thermal contact with the metal heat sink and the heat-conducting panel. This solution uses a heat-conducting panel to absorb heat from the laptop, which is then cooled by a thermoelectric cooler inside the mounting holes. A metal heatsink and fan inside the bottom casing further dissipate heat from the thermoelectric cooler. However, this solution has several drawbacks. Firstly, the heat-conducting panel absorbs heat from the laptop casing, and cooling is only achieved through the thermoelectric cooler, resulting in low efficiency. Secondly, the partial contact between the thermoelectric cooler and the heat-conducting panel leads to uneven temperature distribution, with lower temperatures near the cold end of the cooler and higher temperatures further away. Thirdly, the metal heatsink and fan are only used to dissipate heat from the thermoelectric cooler, making the overall cooling effect less than ideal. Furthermore, the low temperature of the cold end of the thermoelectric cooler during operation causes condensation, affecting its performance and resulting in water accumulation. The condensate also drips onto the desktop, causing inconvenience. Therefore, further improvements to existing laptop coolers are necessary. Utility Model Content
[0004] The purpose of this invention is to solve the problems of existing laptop heat sinks and improve their heat dissipation efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A laptop air conditioner cooler includes an outer casing, a drip tray, a thermoelectric cooler, an upper CPU cooler, and a lower CPU cooler. The top surface of the outer casing has a cold air outlet area, the rear side of the outer casing has a hot air outlet area, and the left and right sides of the outer casing have natural air inlets. The drip tray is fixedly installed inside the outer casing. The thermoelectric cooler is fixedly installed inside the drip tray, with its upper surface being the cold end and its lower surface being the hot end. The upper CPU cooler is fixedly installed inside the drip tray and located above the thermoelectric cooler, while the lower CPU cooler is fixedly installed on the outer side of the bottom surface of the drip tray and located below the thermoelectric cooler.
[0007] In the above design, the drip tray is rectangular, with air inlets on both sides and a drain outlet on the front. This design allows natural air to enter the tray through the air inlets, where it is cooled by the CPU cooler and blown to the cool air outlet on the outer casing, thus cooling the laptop. Condensation generated during this cooling process is collected in the tray and drained through the drain outlet. A drain pipe can be connected to the drain outlet for easy drainage. Alternatively, a plug can be designed at the drain outlet to temporarily store condensate. After a period of time, or when the condensate level rises to a certain height, the plug can be opened, and a cool water pipe connected to drain the condensate. Because the condensate is relatively cold, the incoming natural air can absorb some of its heat, improving the cooler's efficiency to some extent.
[0008] In the above solution, the bottom surface of the water receiving tray has several mounting ports for assembling thermoelectric coolers, and the thermoelectric coolers are embedded in the mounting ports. This design separates the cold end of the upper surface of the thermoelectric cooler from the hot end of the lower surface. Combined with the upper and lower CPU heatsinks, this completely isolates the cold air inside the water receiving tray from the hot air at the bottom of the tray, further improving the heat dissipation efficiency of the heatsink.
[0009] In the above solution, both the upper and lower CPU coolers are equipped with cooling fans. The cooling fan of the upper CPU cooler is positioned above the thermoelectric cooler and is fixedly connected to the bottom surface of the drip tray. The cooling fan of the lower CPU cooler is positioned below the thermoelectric cooler and is fixedly connected to the outer side of the bottom surface of the drip tray. Both the upper and lower CPU coolers can be existing computer CPU coolers with cooling fans. This configuration allows for better integration of the cooling energy from the upper part of the thermoelectric cooler with natural airflow, resulting in cool air output from the top of the outer casing for cooling the laptop. At the bottom of the drip tray, the lower CPU cooler further integrates heat with natural airflow, allowing for better cooling of the hot end of the thermoelectric cooler.
[0010] In the above design, the top surface of the outer cover is tilted at an angle α, which is between 10° and 60°. This design allows the laptop to be placed on the outer cover at a suitable tilt angle, facilitating operation on the laptop and improving user comfort.
[0011] In the above design, the left and right sides of the drip tray are respectively provided with connecting parts, and threaded mounting holes are provided on the connecting parts. The outer cover is fixedly connected to the drip tray by bolts. With this arrangement, the drip tray can maintain the same tilt angle as the outer cover, and the generated condensate can flow to the side of the drain outlet, facilitating the discharge of condensate.
[0012] In the above design, the width and length of the drip tray are adapted to the length and width of the cold air outlet area on the top surface of the outer casing. This design allows the cold air from the drip tray to be directed directly towards the cold air outlet area, improving the heat dissipation efficiency of the laptop.
[0013] In the above design, ventilation holes are distributed in the cold air outlet area, hot air outlet area, and natural air inlet area of the outer cover. The design of the ventilation holes ensures smooth airflow and prevents foreign objects from entering the outer cover.
[0014] This invention has the following advantages: The laptop air conditioner radiator of this invention features a water collection tray in which a thermoelectric cooler is mounted. An upper CPU radiator is positioned above the cold end of the thermoelectric cooler, and a lower CPU radiator is positioned below the hot end of the thermoelectric cooler. The upper CPU radiator combines the cooling energy from the cold end of the thermoelectric cooler with the natural airflow entering the water collection tray to form cool air. This cool air is then blown onto the laptop through the cool air outlet area on the top surface of the outer casing to dissipate heat from the laptop. This design ensures that the temperature of the blown cool air is uniform and improves the heat dissipation efficiency of the laptop air conditioner radiator.
[0015] This invention relates to a laptop air conditioner cooler, which efficiently cools the hot end of a semiconductor cooling chip through a lower CPU cooler, ensuring that the semiconductor cooling chip can stably output cooling capacity at the cold end.
[0016] This utility model of a laptop air conditioner radiator features a water collection tray that collects condensate generated at the cold end of the semiconductor cooling chip during operation. This condensate can be drained through the drain outlet or temporarily retained in the water collection tray to absorb some heat from the natural airflow. Once a certain amount of condensate has accumulated, it is then discharged. This design avoids the impact of condensate on the laptop air conditioner radiator and also prevents condensate from flowing out, thus improving the user experience.
[0017] The notebook air conditioner radiator of this utility model has a simplified structure, uses fewer parts, and is easy to assemble. Attached Figure Description

Detailed Implementation
[0024] The technical solution of this utility model will be clearly and completely described below through embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] like Figure 1-5As shown, the laptop air conditioner radiator of this utility model includes an outer cover 1, a water receiving tray 2, a semiconductor cooling chip 3, an upper CPU radiator 4, and a lower CPU radiator 5.
[0026] like Figure 1-2 As shown, the outer cover 1 can be made of metal or other high-strength materials. The outer cover 1 includes a top surface, front side, rear side, left side, and right side. The bottom of the outer cover 1 has a horizontal opening, and the top surface of the outer cover 1 is set at an angle α to the horizontal plane, with α ranging from 10° to 60°. This design allows the laptop to be placed on the outer cover 1 at a suitable tilt angle, facilitating operation and improving comfort. To ensure the outer cover 1 is completely sealed, a removable base plate can be provided at the bottom of the outer cover 1. The base plate can be fixed to the outer cover with screws.
[0027] A cold air outlet area 11 is provided on the top surface of the outer cover 1, a hot air outlet area 12 is provided on the rear side of the outer cover 1, and natural air inlet areas 13 are provided on the left and right sides of the outer cover 1. Ventilation holes are distributed in the cold air outlet area 11, hot air outlet area 12, and natural air inlet area 13 on the outer cover 1. The design of the ventilation holes ensures smooth airflow and prevents external foreign objects from entering the outer cover.
[0028] like Figure 3-5 As shown, the water receiving tray 2 is a rectangular water receiving tray with air inlets 21 on the left and right sides and a drain outlet 22 on the front side.
[0029] The length and width of the drip tray 2 are adapted to the length and width of the cold air outlet area 11 on the top surface of the outer casing 1. This design allows the cold air in the drip tray 2 to be directed directly towards the cold air outlet area 11, improving the heat dissipation efficiency of the laptop.
[0030] With this design, natural air can enter the drip tray 2 through the air inlet 21, where it is cooled by the CPU cooler 4 and blown into the cool air outlet 11 on the outer casing 1, thus cooling the laptop. The condensate produced during this cooling process remains in the drip tray 2 and can be drained through the drain outlet 22. During use, a drain pipe can be connected to the drain outlet 22 for easy drainage. Alternatively, a plug can be designed at the drain outlet to temporarily store the condensate in the drip tray. After a period of time, or when the condensate level rises to a certain height, the plug can be opened, and a cold water pipe can be connected to drain the condensate. Because the condensate is at a low temperature, the natural air entering the drip tray can also absorb some of the heat from the condensate, thus improving the heat dissipation efficiency of the cooler to some extent.
[0031] The bottom surface of the drip tray 2 has several mounting ports 23 for mounting thermoelectric coolers 3, which are embedded in the mounting ports 23. This arrangement separates the cold end 31 of the upper surface of the thermoelectric cooler 3 from the hot end 32 of the lower surface. Combined with the upper CPU heatsink 3 and the lower CPU heatsink 4, the cold air inside the drip tray 2 and the hot air at the bottom of the drip tray 2 are completely isolated, further improving the heat dissipation efficiency of the heatsink.
[0032] The left and right sides of the drip tray 2 are respectively provided with connecting parts 24, and the connecting parts 24 are provided with threaded mounting holes. The drip tray 2 is fixedly installed inside the outer cover 1, and the outer cover 1 is fixedly connected to the drip tray 2 by bolts. With this arrangement, the drip tray 2 can maintain the same tilt angle as the outer cover 1, and the generated condensate can flow to one side of the drain outlet 22, which facilitates the discharge of condensate.
[0033] like Figure 5 As shown, the thermoelectric cooler 3 can be an existing thermoelectric cooler, and it is connected to a power source via wires. The upper end face of the thermoelectric cooler 3 is the cold end 31, and the lower end face is the hot end 32. The thermoelectric cooler 3 is embedded in the mounting opening 23 on the bottom surface of the water receiving tray 2. During installation, it can be fixed and bonded with sealant, or a connector can be provided on its outer side for welding connection. To ensure the seal at the mounting opening, a sealing ring can also be provided.
[0034] The number of thermoelectric coolers 3 installed in the water receiving tray 2 can be selected according to the heat dissipation needs. For example, one, two, three or more groups of thermoelectric coolers can be installed. An upper CPU heatsink 4 is installed above each group of thermoelectric coolers, and a lower CPU heatsink 5 is installed below each group of thermoelectric coolers 3.
[0035] like Figure 3 As shown, both the upper CPU heatsink 4 and the lower CPU heatsink 5 are heatsinks equipped with cooling fans. The cooling fan of the upper CPU heatsink 4 is positioned above the thermoelectric cooler 3, and the upper CPU heatsink 4 is fixedly connected to the bottom surface of the water receiving tray 2. Figure 2 As shown, the cooling fan of the lower CPU heatsink 5 is located below the thermoelectric cooler 3, and the lower CPU heatsink 5 is fixedly connected to the outer side of the bottom surface of the drip tray 2. Both the upper CPU heatsink 4 and the lower CPU heatsink 5 can be heatsinks with cooling fans that are already used on computer CPUs. This arrangement allows the cooling energy at the top of the thermoelectric cooler 3 to be better integrated with the natural airflow, resulting in cool air output from the top of the outer casing for cooling the laptop. At the bottom of the drip tray 2, the lower CPU heatsink 5 further integrates the heat with the natural airflow, allowing the hot end 32 at the bottom of the thermoelectric cooler 3 to be cooled more effectively.
[0036] This utility model of a laptop air conditioner cooler, when in use, is connected to a power source, which provides electrical energy to the thermoelectric cooler, upper CPU cooler, and lower CPU cooler. The cold end of the upper surface of the thermoelectric cooler generates cooling, while the hot end of the lower surface accumulates heat. When the fan of the upper CPU cooler rotates, some natural air enters the outer casing through the natural air intake areas on the left and right sides of the casing, and then enters the water tray through the air inlets on the left and right sides of the water tray. Under the negative pressure created by the rotation of the upper CPU cooler fan, the air enters the upper CPU cooler and passes through the cold end of the thermoelectric cooler, cooling the natural air into cold air, which is then blown out from above the fan and directed towards the cold air outlet area on the top surface of the casing, thus cooling the laptop. At the same time, under the negative pressure generated by the fan rotating on the lower CPU cooler, some natural air enters the lower CPU cooler, passes through the hot end of the thermoelectric cooler, absorbs heat, and is discharged through the hot air outlet area on the rear side of the outer casing. This design allows the heat from the hot end of the thermoelectric cooler to be released in time, ensuring that the cold end of the thermoelectric cooler can continuously generate low temperatures, thereby improving the heat dissipation efficiency of the laptop air conditioner cooler.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
