Description

Technical Field

[0001] The utility model relates to the field of laboratory heat dissipation, in particular to a laboratory rapid heat discharge device. Background Art

[0002] A large number of test equipment are stored in the daily operation of the laboratory. When these devices are in continuous operation, a large amount of heat will be generated on the surface of the components in the equipment. The accumulation of heat will cause the equipment to shut down due to excessive temperature or malfunction and become unusable. Therefore, a fan is installed in the component assembly box of the equipment to quickly discharge the internal heat out of the electrical box, so that the components in the box will not cause a large amount of heat accumulation, forming an air-cooled heat dissipation test equipment.

[0003] However, due to the excessive number of air-cooled test equipment in the laboratory and the small laboratory space, the heat discharged by the equipment accumulates in the laboratory, resulting in the inability of the air-cooled test equipment to achieve heat exchange through fans. Therefore, it is necessary to quickly discharge the heat generated by the air-cooled test equipment during operation in the laboratory to reduce the heat load of the laboratory and reduce the cost investment in air conditioning and refrigeration.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] As shown in the figure, this embodiment provides a laboratory rapid heat discharge device, including an air duct 1 and an air hood 2. The air duct 1 is arranged in the laboratory area and communicates with the air hood 2. A fan 5 is installed at the rear end of the air hood 2. The output end of the fan 5 is connected to a discharge pipe 6. A check valve 7 is installed in the discharge pipe 6.

[0020] It also includes a temperature sensor 3 for detecting the temperature in the air duct 1 and the air cover 2, and a controller 4 for feeding back the temperature through the temperature sensor 3 and controlling the start-up fan 5 to start or shut down.

[0021] On the basis of the above, a swing blade 22 is installed in the wind shield 2, and the swing blade 22 is connected to the cam crank mechanism for driving, so as to control the opening amplitude of the wind shield 2;

[0022] Reference Figure 2-3 As shown, the cam crank mechanism includes a cylindrical cam, a cam groove is arranged on the circumference of the cylindrical cam, and the cylindrical cam is driven to rotate by a motor;

[0023] One end of the swing blade 22 is fixedly connected to a rotating shaft 28, one end of the rotating shaft 28 is connected to a crank 29, and the outer side of the crank 29 is connected to a driving column 23, and the driving column 23 is embedded in the cam groove. The swing blades 22 are arranged in multiple groups at intervals, and the cam grooves are arranged in multiple layers corresponding to the swing blades 22. A dust shielding plate 21 is fixedly installed in the gap between adjacent swing blades 22. A bracket 27 is installed on one side of the swing blade 22, and the rotating shaft 28 is rotatably supported in the axial hole opened by the bracket 27. By starting the motor, when the cam rotates, the cam groove drives the driving column 23 to swing, thereby controlling the swing blade 22 to swing up and down. The swing of the swing blade can rectify the wind speed and control the size of the air outlet and the wind speed. When there is no heat dissipation, the swing blade can be controlled to be in a closed state, and it works together with the dust shielding plate 21 to make it closed, so as to achieve a dust-proof effect.

[0024] In addition, the swing amplitude of the swing blade can be changed according to different internal heat dissipation requirements. For specific design, please refer to Figure 2 As shown, each layer of cam grooves on the cylindrical cam has a different path. For example, in the figure, it includes a first layer of cam grooves 25 and a second layer of cam grooves 26. The trajectories of these two cam grooves are different, and the swing amplitudes of the pendulum blades are different during rotation. The drive column 23 connected to each pendulum blade 22 is a telescopic structure, and the drive column 23 of each pendulum blade is hinged with a connecting rod 24. The connecting rod 24 links all the pendulum blade movements together. The drive column 23 is a telescopic structure, and an electric push rod can be used at the front end to achieve telescoping. Figure 2 As shown, the swing amplitude can be selected according to the cam groove. For example, if the swing amplitude of the first layer cam groove 25 is selected, the driving pillars 23 of the second and third layers of the swing leaves are controlled to retract, and the driving pillars 23 of the first layer of the swing leaves are driven to extend into the first layer cam groove 25, so that all the swing leaves are controlled by the first layer cam groove 25. In actual application, it is determined according to the heat dissipation requirements. If the internal temperature is high, a cam groove with a larger swing amplitude can be selected for switching.
