Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of heat exchanger equipment, and in particular relates to a gravity heat pipe heat exchanger. Background Technology
[0002] A gravity heat pipe heat exchanger is a device that uses the temperature difference between indoors and outdoors and gravity for heat exchange. Its structure mainly consists of a housing, indoor and outdoor fans, an evaporator, a condenser, connecting pipes, and a control panel assembly. During operation, the refrigerant evaporates and absorbs heat in the indoor evaporator, turning into a gaseous state and carrying away heat. The gaseous refrigerant then flows through the pipes to the outdoor condenser. Due to the lower outdoor temperature, the refrigerant condenses and releases heat, turning into a liquid state and transferring heat to the outdoor air. Simultaneously, the liquid refrigerant flows into the indoor evaporator under gravity to continue evaporating and absorbing heat. This cycle of heat exchange achieves the purpose of cooling.
[0003] Currently, most gravity heat pipe heat exchangers are prone to dust accumulation on the outer wall of the heat sink during use, which affects the heat conduction effect. Therefore, cleaning components are used to clean the surface. However, with traditional cleaning methods, the airflow is relatively dispersed due to the distance between the fan and the heat sink, making it difficult to blow the cleaned dust outward. As a result, some dust adheres to the heat sink wall, affecting the heat conduction effect of the heat sink. Utility Model Content
[0004] The purpose of this invention is to provide a gravity heat pipe heat exchanger that solves the existing problems.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a gravity heat pipe heat exchanger, including a cleaning component, a drive mechanism, a baffle, and a linkage mechanism; The cleaning component includes a mounting plate and a cleaning block fixed to the mounting plate. The cleaning block is located between the pipe gaps of the heat sink and can slide along the pipe gaps to clean the surface of the heat sink. The drive mechanism is used to drive the mounting plate to move, so as to cause the cleaning block to slide along the first direction, which is the extension direction of the pipe seam; The linkage mechanism connects the mounting plate and the baffle, converting the movement of the mounting plate into the rotation of the baffle, so as to adjust the rotation angle of the baffle to block and concentrate the airflow towards the cleaned area.
[0006] Furthermore, the cleaning component also includes a limiting sleeve and a limiting rod; The limiting rod extending along the first direction is fixed to the heat exchanger body; The two limiting sleeves are respectively fixed to both ends of the mounting plate in the second direction and slidably sleeved outside the limiting rod. The second direction is perpendicular to the first direction and is the axis of the fan.
[0007] Furthermore, the drive mechanism includes a lead screw, a motor, and a stationary block; The fixing block is fixed inside the heat exchanger body and is located between the two limiting rods; The lead screw, extending in the first direction, is threadedly connected to the mounting plate; One axial end of the lead screw is connected to the output end of the motor, and the other axial end is rotatably connected to the fixed block.
[0008] Furthermore, the linkage mechanism includes a gear block, a gear, and a rotating shaft; The toothed block is fixed to the limiting sleeve; A gear is fitted onto each of the two axial ends of the rotating shaft extending in the second direction; The gear meshes with the tooth block; The baffle is fixedly installed on the rotating shaft.
[0009] Furthermore, the linkage mechanism also includes a ratchet component; The ratchet is mounted on the shaft and engages with the gear to limit the shaft's unidirectional rotation.
[0010] Furthermore, the linkage mechanism also includes a connector and a torsion spring; The shaft is rotatably connected to the inner wall of the heat exchanger body via the connector. The torsion spring is fitted onto the connector head and is used to provide the torque for resetting the baffle.
[0011] Furthermore, the shape of the cleaning block matches the gap between the heat sink pipes.
[0012] Furthermore, it also includes: The controller is located on the heat exchanger body and is electrically connected to the motor.
[0013] This utility model has the following beneficial effects: This invention utilizes an electrically driven lead screw to move the mounting plate up and down, causing the cleaning blocks located between the heat sink pipe seams to clean the heat sink pipe walls. Simultaneously, as the mounting plate slides, the toothed blocks at both ends of the mounting plate move upwards and engage with gears at corresponding heights. This, in conjunction with the ratchet and rotating shaft, causes the baffle to rotate, making it perpendicular to the heat sink and blocking the airflow generated by the fan. This results in a larger and faster airflow in the cleaned area of the heat sink, blowing dust outwards and improving the cleaning effect.
[0014] This invention utilizes baffles of different heights that flip vertically relative to the heat sink. When the baffle on one side of the fan flips, the diameter of the ventilation opening is reduced, which accelerates the airflow at the location of the flipped baffle, resulting in better heat dissipation of the heat sink at that location.
[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-6 This utility model is a gravity heat pipe heat exchanger, including a heat exchanger body 1, a partition 3 is provided on the inner wall of the heat exchanger body 1, and two sets of fans 2 are arranged diagonally on the partition 3. Two heat dissipation components 4 are provided on both sides of the partition 3 inside the heat exchanger body 1, and it also includes: Fixing blocks 7 are set on the surface of partition 3, and two of them are provided; There are multiple limit rods 6, which are set in pairs and are located at the top and bottom of the heat exchanger body 1. There are two cleaning components 5, which are located inside the heat exchanger body 1 directly opposite the heat sink 4, and are used to clean and remove dust from the area around the heat sink 4.
[0021] Furthermore, the cleaning component 5 includes a limiting sleeve 56 disposed on the outer wall of the two limiting rods 6, and a plurality of rotating shafts 50 located inside the heat exchanger body 1. The outer walls of the two limiting sleeves 56 are fixedly connected with toothed blocks 57, and a mounting plate 52 is connected between the two toothed blocks 57. Two cleaning blocks 55 are sequentially connected to the outer wall of the mounting plate 52. Multiple rotating shafts 50 are fixedly connected to baffles 59 on their outer walls, and gears 58 are sleeved on both ends of the outer walls of the rotating shafts 50. Ratchet 51 is fitted on both ends of the outer wall of multiple rotating shafts 50. The multiple ratchet 51 cooperate with the corresponding gears 58. By using the limit sleeve 56, tooth block 57 and mounting plate 52 to slide upward, the cleaning block 55 is driven to slide upward, which can scrape the dust attached to the outer wall of the heat sink 4, making the dust loose. At the same time, under the action of the ratchet 51, the upward movement of the tooth block 57 can cause the corresponding gear 58 to drive the ratchet 51, rotating shaft 50 and baffle 59 to rotate, causing the baffle 59 to flip and block the wind, making the airflow in the area of the baffle 59 larger, which can better blow the dust outward.
[0022] Furthermore, the cleaning component 5 also includes two motors 54 disposed inside the heat exchanger body 1. The output end of the motor 54 is connected to a lead screw 53, and the lead screw 53 is threaded through the mounting plate 52 and rotatably connected to the fixing block 7. Multiple gears 58 are rotatably connected to the inner wall of the heat exchanger body 1, and a torsion spring 9 is fixedly installed on the outer wall of the connector 8 between the gear 58 and the heat exchanger body 1. The motor 54 drives the lead screw 53 to rotate, causing the mounting plate 52 to slide up and down. The connector 8 and torsion spring 9 between the gear 58 and the inner wall of the heat exchanger body 1 can cause the gear 58 to drive the rotating shaft 50 and the baffle 59 to return to their original position under the action of the ratchet 51 after the tooth block 57 separates from the gear 58.
[0023] Furthermore, the tooth block 57 and the gear 58 are meshed together.
[0024] Furthermore, the wind force generated by the fan 2 is less than the sum of the weight of the baffle 59 and the torque of the torsion spring 9. With the help of the torque of the torsion spring 9, the baffle 59 can be flipped downwards more effectively.
[0025] Furthermore, the cleaning block 55 slides between the slots of the heat sink 4.
[0026] Furthermore, a controller 10 is provided on the front end face of the heat exchanger body 1, and the controller 10 is electrically connected to the corresponding electronic device inside the heat exchanger body 1.
[0027] One specific application of this embodiment is as follows: During use, the controller 10 at the front end of the heat exchanger body 1 is first electrically connected to the corresponding electronic components inside the heat exchanger body 1 (existing technology). Then, during use, the motor 54 drives the lead screw 53 to rotate, causing the lead screw 53 to slide along the limit rod 6, along with the mounting plate 52, toothed block 57, and limiting sleeve 56. This causes the cleaning block 55 to slide along the gaps between the pipes of the heat sink 4, scraping and cleaning the dust around the heat sink 4, thus loosening the dust. As the toothed block 57 slides upward, it drives the gear 58 to rotate. Since a ratchet 51 is provided on the outer wall of the rotating shaft 50, the ratchet 51 and the gear 58 cooperate with each other, so that the gear 58 can drive the rotating shaft 50 and the baffle 59 to rotate. By utilizing the rotation of the baffle 59, the airflow can be blocked, so that the airflow comes into contact with the baffle 59 and blows directly onto the heat sink 4. At this time, the airflow is large and the flow rate is fast, so that the dust in the already cleaned heat sink 4 area can be blown out quickly, thus making the dust cleaning effect better.
[0028] It should be noted that when gear 58 separates from tooth block 57, the baffle 59 will return to its original position due to the torque of torsion spring 9 and the gravity of baffle 59. (The ratchet 51 and gear 58 are used to make the shaft 50 rotate when gear 58 rotates forward, and the shaft 50 will not rotate when gear 58 rotates in reverse. This is the prior art.)
[0029] During this process, when the baffle 59 located on the side closer to the fan 2 flips, it can block the airflow and at the same time reduce the diameter of the exhaust port, causing the airflow at the flipped baffle 59 to be larger and faster, thus making the heat dissipation effect of the heat sink 4 pipe wall in this area better and the cooling more obvious.
