Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a UPS chassis radiator. Background Art

[0002] In the field of industrial production, UPS equipment is widely used in various key equipment and systems, such as production lines, data centers, automation equipment, etc. These devices have very high requirements for power supply. Once the power is interrupted or unstable, it will lead to serious consequences such as production suspension and data loss. Therefore, the application of UPS chassis heat sink technology can ensure that these key equipment maintain good heat dissipation performance while continuously supplying power, thereby ensuring the smooth progress of industrial production. The application prospect of UPS chassis heat sink technology in the field of industrial production is very broad, and its technical background mainly involves the heat management problem generated by UPS (uninterruptible power supply) equipment during operation. As a key component of the power system, the stable operation of UPS equipment is crucial to ensure the continuous supply of various power needs. However, during the continuous power supply process of UPS equipment, its internal electronic components, batteries and other components will generate a lot of heat. If this heat cannot be dissipated in a timely and effective manner, it will have an adverse effect on the performance, stability and life of the UPS equipment.

[0003] The batteries used in UPS are very sensitive to temperature. When the temperature exceeds 25°C, the battery life will be shortened by more than half. Therefore, keeping the UPS device running within a suitable temperature range is crucial to ensure its battery life. However, the UPS chassis radiators currently on the market generally have certain limitations in terms of heat dissipation efficiency. These radiators often cannot effectively discharge the heat generated inside the UPS device in a timely manner, causing the temperature of the device to continue to rise when running in a high-temperature environment, which in turn affects the performance and life of the battery. In addition, some radiators are not designed reasonably and may have problems such as uneven heat dissipation, which further affects the operation effect and user experience of the UPS device. These problems limit the operation ability of the UPS device in a high-temperature environment. Therefore, it is urgent to improve the cooling efficiency. Therefore, we propose a UPS chassis radiator. Utility Model Content

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purposes of increasing heat dissipation efficiency, the utility model provides the following technical solutions: a UPS chassis radiator, comprising a heat dissipation chassis, the heat dissipation chassis is a cubic box with a hollow interior, a storage plate is designed inside the heat dissipation chassis, the outer periphery of the storage plate is fixedly connected to the inner wall of the heat dissipation chassis, and the inner periphery forms an inverted U shape along the three walls of the heat dissipation chassis except the door, the upper surface of the storage plate is used to place internal components of the UPS power supply, the bottom of the heat dissipation chassis is designed with a ventilation plate, the ventilation plate is designed with small holes for ventilation, the ventilation plate is fixedly connected to the bottom of the heat dissipation chassis, a guide cover is installed on the upper part of the heat dissipation chassis, an inclined groove is designed inside the guide cover, the groove has the same inclination angle, and the inclination direction is clockwise, a fan is installed on the upper part of the guide cover, the surface of the fan blade is a curved surface with an arc, the fan blade forms an inclination angle with the horizontal plane, the blade thickness of the fan blade decreases from the inside to the outside, the blade width increases from the inside to the outside, and the fan air inlet faces the inside of the heat dissipation chassis.

[0008] Preferably, two fixing rods are designed at the rear of the fan, the fixing rods are cross-connected, the intersection is the central axis of the fan, and both ends of the fixing rods are fixedly connected to the fan casing respectively.

[0009] Preferably, the fan housing and the inner wall of the air guide cover are both in the shape of a rounded square.

[0010] Preferably, the air guide cover, the fan and the heat dissipation chassis are detachably connected.

[0011] Preferably, the inclination direction of the air guide cover groove is the same as the rotation direction of the fan.

[0012] Preferably, the inclined groove designed on the air guide cover is arc-shaped and runs through the inner wall of the air guide cover.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a UPS chassis radiator, which has the following beneficial effects:

[0015] 1. This UPS chassis radiator has a shroud and a fan on the top of the heat dissipation chassis. The inner wall of the shroud is designed with inclined grooves arranged in a clockwise direction. The fan blades are approximately spiral, thin in the front and thick in the back, wide in the front and narrow in the back. The blades have an inclination angle with the horizontal plane. The inner wall of the fan housing and the inner wall of the shroud are rounded squares. The grooves on the inner wall of the shroud are arc-shaped, which minimizes the wind resistance of the fan housing and the inner wall of the shroud to the fan. The fan air inlet faces the inside of the heat dissipation chassis. When the UPS power supply starts working, the inverter, energy storage battery and other equipment will generate a lot of heat. The heat makes the air inside the heat dissipation chassis expand due to heat, and then rises to the top through the channel formed between the storage boards. When the UPS power supply is turned on, the fan located at the top of the heat dissipation chassis is powered on and starts working. When the fan is started, as the fan rotates, due to the design of the fan blade shape and tilt angle, the air is sucked in and blown out along the air guide cover in a spiral shape in a certain direction. This spiral wind force not only effectively blows away the heat gathered at the top, but also the air flow is further formed and strengthened into a spiral columnar wind under the action of the inclined groove on the inner wall of the air guide cover. The spiral columnar wind blows directly to the bottom of the heat dissipation chassis, passes through each storage board along the way, takes away the heat of the equipment on the storage board one by one, and finally is discharged after passing through the ventilation plate at the bottom of the heat dissipation chassis. The spiral columnar wind generated by this design can better reach every corner inside the heat dissipation chassis, whether it is the equipment at the top or the line at the bottom, it can be effectively cooled. This not only greatly improves the heat dissipation efficiency of the UPS power supply, but also helps to protect the power supply life, so that it can better provide users with stable and reliable power support.

[0016] 2. A UPS chassis radiator, the heat dissipation chassis is designed with an inverted U-shaped storage board along the three chassis inner walls except the door, and the UPS power supply internal components are placed above the storage board. The shape of the storage board allows the columnar wind formed by the upper fan to blow directly to the ventilation plate at the bottom of the heat dissipation chassis, so that the heat dissipation effect is significantly improved, effectively avoiding the performance degradation or failure of the equipment caused by heat accumulation, and the reservation of the middle space also provides great convenience for the connection, arrangement and installation of the lines inside the UPS power supply chassis. Such a design prevents the internal structure of the chassis from being too crowded, avoids the heat accumulation caused by the messy lines, and also facilitates the connection, arrangement and installation of the lines inside the UPS power supply chassis. When the user needs to open the UPS chassis door for maintenance or inspection, this design makes the internal structure clear at a glance, which is convenient for quickly locating the problem and handling it. This not only reduces the difficulty of maintenance, but also improves work efficiency, making the maintenance of the UPS power supply simpler and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0026] See also Figure 1-5A UPS chassis radiator comprises a heat dissipation chassis 1, which is a cubic box with a hollow interior. A storage plate 2 is designed inside the heat dissipation chassis 1. The outer periphery of the storage plate 2 is fixedly connected to the inner wall of the heat dissipation chassis 1. The inner periphery forms an inverted U shape along the three walls of the heat dissipation chassis 1 except the door. The upper surface of the storage plate 2 is used to place internal components of a UPS power supply. A ventilation plate 3 is designed at the bottom of the heat dissipation chassis 1. The ventilation plate 3 is designed with small holes for ventilation. The ventilation plate 3 is fixedly connected to the bottom of the heat dissipation chassis 1. A guide cover 5 is installed on the upper part of the heat dissipation chassis 1. An inclined groove is designed inside the guide cover 5. The inclined groove designed on the guide cover 5 is arc-shaped and runs through the inner wall of the guide cover 5. The grooves on the four sides have the same inclination angle, the inclination direction is clockwise, and the inclination direction of the groove of the guide cover 5 is the same as the rotation direction of the fan 4. A fan 4 is installed on the upper part of the air deflector 5. The fan casing 7 and the inner wall of the air deflector 5 are both in the shape of a rounded square. Two fixing rods 6 are designed at the rear of the fan 4. The fixing rods 6 are cross-connected, and the intersection is the central axis of the fan 4. Both ends of the fixing rods 6 are fixedly connected to the fan casing 7 respectively. The surface of the fan 4 blade is a curved surface with an arc. The fan 4 blade forms an inclination angle with the horizontal plane. The blade thickness of the fan 4 blade decreases from the inside to the outside, and the blade width increases from the inside to the outside. The air inlet of the fan 4 faces the inside of the heat dissipation chassis 1. The air deflector 5, the fan 4 and the heat dissipation chassis 1 are detachably connected.

[0027] like Figure 3-5As shown, the top of the heat dissipation chassis 1 is designed with a shroud 5 and a fan 4. The inner wall of the shroud 5 is designed with inclined grooves arranged in a clockwise direction. The blades of the fan 4 are approximately spiral-shaped, thin at the front and thick at the back, wide at the front and narrow at the back, and the blades have an inclination angle with the horizontal plane. The inner walls of the fan housing 7 and the shroud 5 are rounded squares, and the grooves on the inner wall of the shroud 5 are arc-shaped, which minimizes the wind resistance of the fan housing 7 and the inner walls of the shroud 5 to the fan 4, and the air inlet surface of the fan 4 faces the inside of the heat dissipation chassis 1. When the UPS power supply starts to work, the inverter, energy storage battery and other equipment installed on the storage board 2 start to generate heat, causing the air inside the heat dissipation chassis 1 to expand due to the heat, and rise to the top through the channel formed between the storage boards 2. At the same time as the UPS power supply is turned on, the fan 4 located at the top of the heat dissipation chassis 1 is powered on and starts to work. When the fan 4 is started, as the fan 4 rotates, due to the design of the fan blade shape and the tilt angle, the air is sucked in and blown out along the air guide 5 in a spiral shape along a certain direction, blowing away the heat accumulated at the top, and the air flow is formed and strengthened into a spiral columnar wind under the action of the inclined grooves on the inner wall of the air guide 5. The spiral columnar wind blows to the bottom of the heat dissipation chassis 1, passes through each storage board 2 along the way and takes away the heat of the equipment on the storage board 2, and finally reaches the ventilation plate 3 at the bottom of the heat dissipation chassis 1 and is discharged. The spiral columnar wind generated by this design can better reach every corner inside the heat dissipation chassis 1, whether it is the equipment at the top or the circuit at the bottom, it can be effectively cooled. This not only greatly improves the heat dissipation efficiency of the UPS power supply, but also helps to protect the power supply life, enabling it to better provide users with stable and reliable power support.

[0028] like Figure 1-2 As shown, the heat dissipation chassis 1 is designed with an inverted U-shaped storage board 2 along the three inner walls of the chassis except the door. The internal components of the UPS power supply are placed above the storage board 2. The shape of the storage board 2 allows the columnar wind formed by the upper fan 4 to blow directly to the ventilation board 3 at the bottom of the heat dissipation chassis 1, so that the heat dissipation effect is significantly improved, effectively avoiding the performance degradation or failure of the equipment that may be caused by heat accumulation. The reservation of the middle space also provides great convenience for the connection, arrangement and installation of the lines inside the UPS power supply chassis. Such a design prevents the internal structure of the chassis from being too crowded, avoids the heat accumulation caused by the disordered lines, and also facilitates the connection, arrangement and installation of the lines inside the UPS power supply chassis. When the user needs to open the UPS chassis door for maintenance or inspection, this design makes the internal structure clear at a glance, which is convenient for quickly locating the problem and handling it. This not only reduces the difficulty of maintenance, but also improves the work efficiency, making the maintenance of the UPS power supply simpler and more efficient.
