Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a radiator. Background Technology

[0002] A radiator is a device that uses a cooling fan to dissipate heat from an object into the environment. Since radiators are often used in enclosed environments such as cabinets and chassis, the hot air blown away by the radiator exchanges heat with the outside environment through the ventilation holes on the chassis. This can easily cause the ambient temperature inside the chassis to rise, and heat to accumulate in the area where the radiator blows air, thus affecting the heat dissipation effect. Utility Model Content

The heat transfer element is fitted onto the mounting bracket, and the cooling fan is mounted on the heat transfer element. The cooling box has an air inlet and an air outlet communicating with the external environment. The cooling box covers the cooling fan. The air inlet and air outlet of the cooling box are connected in a line that intersects the axial direction of the cooling fan. The cross-section of the box decreases along the direction of the air outlet.

[0004] Furthermore, the heat dissipation box includes a box body and a fan. The box body covers the heat dissipation fan. The air inlet and the air outlet are located at both ends of the box body, and the fan is installed on one side of the air inlet.

[0005] Furthermore, the top wall of the housing slopes downward, and the end of the top wall of the housing slopes downward toward the air outlet.

[0006] Furthermore, the housing includes a baffle plate located on one side of the air outlet, the baffle plate being inclined toward the side of the air outlet, and the vertical projection of the baffle plate being tangent to the side wall of the housing.

[0007] Furthermore, the vertical projection of the guide plate is S-shaped.

[0008] Furthermore, the enclosure also includes multiple dustproof nets, which are installed at the air inlet.

[0009] Furthermore, the heat dissipation box also includes an air guide shroud, which is installed at the air outlet. The air guide shroud is composed of multiple relatively rotatable pipe sections and is connected to the external environment of the enclosed box.

[0010] Furthermore, the mounting bracket includes a heat-conducting surface, the heat transfer element is mounted on the heat-conducting surface, and the heat-conducting surface is provided with a plurality of heat dissipation holes, which are equidistantly arranged on the heat-conducting surface.

[0011] Furthermore, the heat sink also includes a temperature sensor mounted on the heat-conducting surface.

[0012] Furthermore, the heat transfer element is a heat sink, which is inserted into the mounting bracket. The heat sink is composed of multiple metal fins, most of which are equidistant. The cooling fan is mounted on the metal fins.

[0013] The advantage of this invention is that by changing the direction of the hot air flow from the cooling fan through the heat dissipation box, the hot air is guided from inside the sealed box to the external environment, thus avoiding the stagnation of hot air inside the sealed box and improving the heat dissipation efficiency of the radiator.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / as well" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] The following describes the embodiments in conjunction with the appendix. Figure 1-4 This utility model will be described in further detail.

[0019] A radiator includes a mounting bracket 1, a heat transfer component 2, a cooling fan 3, and a cooling box 4.

[0020] The mounting bracket 1 is provided with a heat-conducting surface 11, which is made of metal and is used to conduct heat. The heat-conducting surface 11 is provided with heat dissipation holes 12. There are multiple heat dissipation holes 12, which are equidistantly arranged on the heat-conducting surface 11, so that heat can be evenly transferred from one side of the mounting bracket 1 to the other side, avoiding heat accumulation in local areas. The shape of the heat dissipation holes 12 can be oblong, circular, square, or any combination thereof.

[0021] The heat transfer element 2 is configured as a heat sink. In this embodiment, the heat sink is composed of multiple metal fins, which are spaced apart. The fins are made of lightweight, thermally conductive cast aluminum or copper. The surface of the fins is anodized or coated with graphene to enhance the heat radiation heat dissipation capacity. The heat transfer element 2 can also be a heat pipe assembly, a heat spreader, or other heat-conducting components.

[0022] The heat dissipation air box 4 includes a fan 41, a box body 42, an air inlet 43, an air outlet 44, a dust filter 45, and an air guide shroud 46. The air inlet 43 and the air outlet 44 are located on both sides of the box body 42 to form a ventilation duct. The fan 41 is fixed to the box body 42 and is located on one side of the air inlet 43 to provide airflow to the heat dissipation air box 4. Specifically, in this embodiment, the fan 41 can be a centrifugal fan to overcome the airflow resistance and provide higher air pressure within the limited channel space. The air guide shroud 46 is installed at the air outlet 44 to allow the fan to... The airflow generated by 41 is guided to other positions through the air guide hood 46; the dustproof net 45 is installed at the air inlet 43, specifically, there are multiple dustproof nets 45, which are equidistantly arranged; the air guide hood 46 is installed at the air outlet 44 to guide the airflow out. The air guide hood 46 is composed of multiple sections of pipe that can rotate relative to each other, so that the air guide hood 46 can change the exhaust direction. The length of the air guide hood 46 can be freely increased or decreased, and the curvature can be changed, so that the air guide hood 46 can change the exhaust direction, which is suitable for the exhaust of hot air in various environments.

[0023] The top wall of the housing 42 slopes downward toward the air outlet 44, reducing the cross-sectional area of ​​the housing 42. The housing 42 is also equipped with a guide plate 421, which is located at the front end of the air outlet 44. The guide plate 421 is inclined, and its vertical projection is tangent to the side wall of the housing 42, increasing the smoothness of airflow. Specifically, the vertical projection of the guide plate 421 is S-shaped, allowing airflow to smoothly enter from a large ventilation area to a small ventilation area, reducing air pressure loss. The reduction in the cross-section of the rear of the housing 42 forms a diffusion-convergence type air duct. This structure enhances air pressure and increases airflow velocity, thereby accelerating heat transfer.

[0024] The enclosure 42 and dustproof net 45 are made of galvanized steel plate, stainless steel or special engineering plastics to improve the corrosion resistance of the enclosure 42 and dustproof net 45.

[0025] The radiator is also equipped with a control unit that is electrically connected to the temperature sensor 5. The control unit controls the speed of the cooling fan 3 and the blower 41 through the temperature signal based on the real-time temperature, so as to realize multi-level adjustment from low speed and quiet operation to high speed and strong cooling, thereby improving intelligence.

[0026] A structural relationship of a heat sink: The heat transfer element 2 is inserted into the heat-conducting surface 11 of the mounting bracket 1 for easy replacement. The cooling fan 3 is installed on the heat transfer element 2, with the heat transfer element 2 located between the mounting bracket 1 and the cooling fan 3. Specifically, the cooling fan 3 is installed on the metal fins of the heat transfer element 2, enabling the cooling fan 3 to effectively dissipate heat from the heat transfer element 2. The housing 42 of the cooling box 4 is installed on the heat dissipation side of the mounting bracket 1, covering the cooling fan 3. The air inlet 43 and the air outlet 44 are located on both sides of the cooling fan 3. Specifically, the housing 42 can be installed on the mounting bracket 1 in various ways. The housing 42 can be fixed to the mounting bracket 1 with screws, or it can be snapped onto the mounting bracket 1 with clips, slots, etc., for easy disassembly. The temperature sensor 5 is installed on the heat-conducting surface 11 to monitor the temperature of the heat-conducting surface 11. The air outlet 44 is connected to the outside of the enclosed housing through the air guide shroud 46, thereby carrying the heat out of the enclosed housing.

[0027] The working principle of a radiator: The mounting bracket 1 is installed on the equipment to be cooled, so that the heat-conducting surface 11 contacts the heat-generating component. The heat transfer component 2 and the cooling fan 3 dissipate the heat into the cooling box 4. The airflow generated by the fan 41 intersects with the airflow generated by the cooling fan 3, so that the hot air blown out by the cooling fan 3 moves along the direction of the box 42 towards the air outlet 44, thereby transferring the hot air to the inside of the closed box and to the external environment, avoiding heat accumulation.

[0028] The advantage of this utility model is that by changing the direction of the hot air flow from the cooling fan 3 through the heat dissipation box 4, the hot air is guided from the inside of the closed box to the outside environment, avoiding the hot air from stagnating in the closed box and improving the heat dissipation efficiency of the radiator.

[0029] The above embodiments only illustrate one implementation of the present utility model, and should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present utility model, and all of these fall within the protection scope of the present utility model.
