Description

Technical Field

[0001] This invention relates to the field of load cell technology, specifically to a heat dissipation device for load cells. Background Technology

[0002] Chinese patent discloses a heat dissipation type high-voltage load cabinet (publication number: CN213753580U). During installation, several support frames are first sequentially embedded into the mounting groove. At this point, the ends of all the first and second connecting plates facing away from the heat dissipation vents are flush. Elastic clips are then placed over the first and second connecting plates and simultaneously fixed to the inner wall of the cabinet, thus securing the first and second connecting plates. This prevents displacement of the entire heat dissipation device in the thickness direction of the support frames. Furthermore, the mounting groove restricts horizontal displacement of the heat dissipation device, ensuring its stable fixation to the heat dissipation vents. When a dust filter on a heat dissipation device is damaged, only the elastic clips at both ends of that device need to be removed and replaced with a new device, eliminating the need to replace all dust filters and heat dissipation devices. This improves the flexibility and practicality of the heat dissipation device and significantly reduces operating costs.

[0003] Although the aforementioned patent allows for the disassembly of the heat dissipation device, the device cannot actively dissipate heat from the air inside the cabinet, resulting in poor heat dissipation. Furthermore, the ventilation holes can easily allow dust from the outside air to enter the cabinet, causing damage to the internal components.

[0004] To address the aforementioned shortcomings, a technical solution is provided. Summary of the Invention

[0005] The technical problem to be solved by this invention is as follows:

[0006] In the existing technology, although the heat dissipation device can be disassembled, the heat dissipation device cannot actively dissipate heat from the air inside the cabinet, resulting in poor heat dissipation effect. Furthermore, the heat dissipation holes can easily allow dust from the outside air to enter the cabinet, causing damage to the internal components.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A heat dissipation device for a load cell includes a cabinet. Fixed plates are fixedly mounted at both ends of the cabinet. Cooling fans are mounted on the fixed plates and slidably mounted on them. These fans can uniformly dissipate heat from the interior of the cabinet, enabling simultaneous heat dissipation from multiple fans. Two cooling fans on each side of the cabinet face opposite directions, with one fan facing inwards and the other facing outwards. A drive assembly is mounted on the fixed plates to drive the cooling fans to reciprocate. A filter assembly is installed inside the cabinet, and a heat-conducting assembly is installed on the top of the cabinet to conduct heat away from the interior.

[0009] Furthermore, a sliding groove is provided on one side of the fixed plate, and the cooling fan is slidably disposed in the sliding groove.

[0010] Furthermore, a plurality of first heat dissipation holes are evenly provided in the middle of the sliding groove, and a plurality of evenly distributed second heat dissipation holes are provided on the side of the cabinet, with both the first and second heat dissipation holes extending into the interior of the cabinet.

[0011] Furthermore, the drive assembly includes a drive motor fixedly mounted on the top of the fixed plate, a first connecting shaft fixedly mounted on the output end of the drive motor, a second connecting shaft connected between the first connecting shaft and the cooling fan, and the two ends of the second connecting shaft being hinged to the first connecting shaft and the cooling fan, respectively.

[0012] Furthermore, the filter assembly includes a first filter plate and a second filter plate. The first filter plate is fixedly disposed inside the cabinet on the side facing the cooling fan inside the cabinet, and the second filter plate is detachably disposed inside the cabinet on the side facing the cooling fan outside the cabinet.

[0013] Furthermore, a U-shaped frame is fixedly installed on one side of the cabinet, the second filter plate is slidably installed inside the U-shaped frame, a through groove is opened on the top of the cabinet, the top of the second filter plate extends into the through groove and is fixedly installed with a lifting handle.

[0014] Furthermore, the heat-conducting component includes a heat-conducting base fixedly installed on the top of the cabinet, the bottom of the heat-conducting base extending into the interior of the cabinet, heat dissipation fins fixedly installed on the bottom of the heat-conducting base, and a heat dissipation box fixedly installed on the top of the heat-conducting base.

[0015] Furthermore, the interior of the heat sink is a hollow structure, and an inlet and an outlet are respectively provided at both ends of the heat sink, which are used for the input and output of cooling water.

[0016] The beneficial effects of this invention are:

[0017] In this invention, one cooling fan dissipates the heat generated by the internal components of the cabinet, accelerating airflow. Another cooling fan drives the air inside the cabinet to be expelled. A drive assembly moves the cooling fan back and forth on a fixed plate, thus achieving uniform airflow and heat dissipation from the cabinet. A single cooling fan achieves the cooling effect of multiple fans, reducing costs. A filter component prevents dust during the cooling process, and a heat-conducting component facilitates heat conduction of the hot air inside the cabinet, improving the cooling effect.

[0018] By configuring the filter components, the first filter plate and the second filter plate can respectively prevent dust from entering the first and second heat dissipation holes on both sides of the cabinet. Since the first filter plate is fixedly installed inside the cabinet on the side facing the cooling fan, when the cooling fan blows air into the cabinet, the first filter plate can prevent dust from the outside of the cabinet from entering the cabinet. However, dust inevitably enters the cabinet. At this time, since the second filter plate is detachably installed inside the cabinet on the side facing the cooling fan, when the cooling fan draws air out of the cabinet, the second filter plate can be pulled up by the handle and pulled out of the through slot, thus facilitating the discharge of dust from the inside of the cabinet. In other words, the first filter plate and the second filter plate can work together with the orientation of the two cooling fans to achieve efficient dust prevention inside the cabinet and improve the dust prevention effect.

[0019] By configuring the heat-conducting components, when the heat generated by the internal components of the cabinet is low, the lighter hot air will concentrate at the top of the cabinet and dissipate heat through the heat dissipation fins. As the heat gradually increases and the heat dissipation fins are insufficient to meet the cooling demand, the cooling water can circulate within the heat dissipation box through the combination of the inlet and outlet, thereby conducting heat to the heat dissipation fins and expelling the heat through the cooling water. When the heat generated by the components cannot be dissipated by the heat-conducting components alone, symmetrically arranged cooling fans will then dissipate the heat inside the cabinet. The purpose of this configuration is to achieve multi-level adjustment. Only when the heat cannot be dissipated through the heat-conducting components will kinetic energy input be released to dissipate the heat inside the cabinet, achieving the goal of saving kinetic energy and reducing cost input.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-5 The present invention provides a technical solution:

[0029] A heat dissipation device for a load cell includes a cabinet 1. Fixed plates 2 are fixedly mounted at both ends of the cabinet 1. A cooling fan 3 is mounted on each fixed plate 2 and slidably mounted on the fixed plate 2. The cooling fan 3 can uniformly dissipate heat from the interior space of the cabinet 1, enabling simultaneous heat dissipation from multiple fans and saving resources. The two cooling fans 3 on opposite sides of the cabinet 1 face opposite directions, with one fan facing inwards and the other facing outwards. A drive assembly 4 is mounted on the fixed plate 2 to drive the cooling fan 3 to reciprocate on the fixed plate 2. A filter assembly 5 is installed inside the cabinet 1, and a heat-conducting assembly 6 is installed on the top of the cabinet 1 to conduct heat from the interior of the cabinet 1.

[0030] During operation, one of the cooling fans 3 blows away the heat generated by the internal components of the cabinet 1, accelerating airflow. In conjunction with another cooling fan 3, it drives the air inside the cabinet 1 to be expelled. The drive component 4 can drive the cooling fan 3 to reciprocate on the fixed plate 2, thereby achieving uniform blowing and heat dissipation of the air inside the cabinet 1 by the cooling fan 3. The cooling effect of multiple fans is achieved by using one cooling fan 3, reducing costs. The filter component 5 can achieve dust prevention during the heat dissipation process, and the heat conduction component 6 can facilitate heat conduction of the hot air inside the cabinet 1, improving the heat dissipation effect.

[0031] As a further embodiment of the present invention:

[0032] The fixed plate 2 has a sliding groove 21 on one side, and the cooling fan 3 is slidably disposed in the sliding groove 21. A plurality of first heat dissipation holes 22 are evenly provided in the middle of the sliding groove 21, and a plurality of evenly distributed second heat dissipation holes 23 are provided on the side of the cabinet 1. The first heat dissipation holes 22 and the second heat dissipation holes 23 both extend into the interior of the cabinet 1.

[0033] The cooling effect of the cooling fan 3 on the interior of the cabinet 1 is improved by setting several first heat dissipation holes 22 and second heat dissipation holes 23.

[0034] As a further embodiment of the present invention:

[0035] The drive assembly 4 includes a drive motor 41 fixedly mounted on the top of the fixed plate 2. The output end of the drive motor 41 is fixedly mounted with a first connecting shaft 42. A second connecting shaft 43 is connected between the first connecting shaft 42 and the cooling fan 3. The two ends of the second connecting shaft 43 are respectively hinged to the first connecting shaft 42 and the cooling fan 3.

[0036] During operation, the first connecting shaft 42 is rotated by the drive motor 41, and the second connecting shaft 43 drives the cooling fan 3 to reciprocate in the sliding groove 21, thereby providing uniform and sufficient heat dissipation for the internal components of the cabinet 1.

[0037] As a further embodiment of the present invention:

[0038] The filter assembly 5 includes a first filter plate 51 and a second filter plate 52. The first filter plate 51 is fixedly installed inside the cabinet 1 on the side of the cooling fan 3 facing the inside of the cabinet 1, and the second filter plate 52 is detachably installed inside the cabinet 1 on the side of the cooling fan 3 facing the outside of the cabinet 1.

[0039] A U-shaped frame 53 is fixedly installed on one side of the interior of the cabinet 1. The second filter plate 52 is slidably installed inside the U-shaped frame 53. A through groove 54 is opened on the top of the cabinet 1. The top of the second filter plate 52 extends to the through groove 54 and is fixedly installed with a lifting handle 55.

[0040] During operation, the first filter plate 51 and the second filter plate 52 can respectively prevent dust from entering the first heat dissipation hole 22 and the second heat dissipation hole 23 on both sides of the cabinet 1. Since the first filter plate 51 is fixedly installed inside the cabinet 1 on the side of the cooling fan 3 facing the inside of the cabinet 1, when the cooling fan 3 blows air into the cabinet 1, the first filter plate 51 can prevent dust from the outside of the cabinet 1 from entering the cabinet 1. However, dust inevitably enters the cabinet 1. At this time, since the second filter plate 52 is detachably installed inside the cabinet 1 on the side of the cooling fan 3 facing the outside of the cabinet 1, when the cooling fan 3 draws the air out of the cabinet 1, the second filter plate 52 can be pulled up by the lifting handle 55 and pulled out from the through groove 54, thereby facilitating the discharge of dust from the inside of the cabinet 1. In other words, the first filter plate 51 and the second filter plate 52 can work together with the orientation of the two cooling fans 3 to achieve efficient dust prevention inside the cabinet 1 and improve the dust prevention effect.

[0041] As a further embodiment of the present invention:

[0042] The heat-conducting component 6 includes a heat-conducting base 61 fixedly installed on the top of the cabinet 1. The bottom of the heat-conducting base 61 extends into the interior of the cabinet 1. Heat dissipation fins 62 are fixedly installed on the bottom of the heat-conducting base 61, and a heat dissipation box 63 is fixedly installed on the top of the heat-conducting base 61.

[0043] The interior of the heat sink 63 is hollow, and the two ends of the heat sink 63 are respectively provided with a water inlet and a water outlet, which are used for the input and output of cooling water, respectively.

[0044] During operation, when the heat generated by the components inside cabinet 1 is relatively small, the lighter hot air will concentrate at the top of cabinet 1 and dissipate heat through the heat dissipation fins 62. As the heat gradually increases, and the heat dissipation fins 62 can no longer meet the heat dissipation requirements, the cooling water can circulate in the heat dissipation box 63 through the combination of the inlet and outlet, thereby conducting heat to the heat dissipation fins 62 and expelling the heat through the cooling water. When the heat generated by the components cannot be dissipated by the heat conduction components 6 alone, the symmetrically arranged cooling fans 3 will dissipate the heat inside cabinet 1. The purpose of this setting is to achieve multi-level adjustment. Only when the heat cannot be dissipated by the heat conduction components 6 will kinetic energy be released to dissipate the heat inside cabinet 1, thereby achieving the purpose of saving kinetic energy and reducing cost input.

[0045] Working principle:

[0046] When the heat generated by the internal components of the cabinet 1 is small, the hot air, being lighter, will concentrate above the cabinet 1 and dissipate heat through the heat dissipation fins 62. As the heat gradually increases and the heat dissipation fins 62 can no longer meet the heat dissipation requirements, the cooling water can circulate in the heat dissipation box 63 through the cooperation of the inlet and outlet, thereby conducting heat to the heat dissipation fins 62 and expelling the heat through the cooling water. When the heat generated by the components cannot be expelled by the heat conduction component 6 alone, one of the cooling fans 3 blows away the heat generated by the internal components of the cabinet 1, accelerating the airflow, and in conjunction with another cooling fan 3, drives the air inside the cabinet 1 to be expelled. The drive component 4 can drive the cooling fan 3 to reciprocate on the fixed plate 2, thereby achieving uniform blowing and heat dissipation of the air inside the cabinet 1 by the cooling fan 3.

[0047] The first filter plate 51 and the second filter plate 52 can respectively prevent dust from entering the first heat dissipation hole 22 and the second heat dissipation hole 23 on both sides of the cabinet 1. Since the first filter plate 51 is fixedly installed inside the cabinet 1 on the side of the cooling fan 3 facing the inside of the cabinet 1, when the cooling fan 3 blows air into the cabinet 1, the first filter plate 51 can prevent dust from the outside of the cabinet 1 from entering the cabinet 1. However, dust will inevitably enter the cabinet 1. At this time, since the second filter plate 52 is detachably installed inside the cabinet 1 on the side of the cooling fan 3 facing the outside of the cabinet 1, when the cooling fan 3 draws the air out of the cabinet 1, the second filter plate 52 can be pulled up by the lifting handle 55 and pulled out from the through groove 54, thereby facilitating the discharge of dust inside the cabinet 1.

[0048] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
