The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1 and 2, a heat dissipating device 100 according to a preferred embodiment of the present disclosure is installed on a control cabinet and is in signal connection with an external control device 300, the control device 300 can interact with the heat dissipating device 100 through a communication device 200, and the control device 300 can control the heat dissipating device 100.
A plurality of components of different types are arranged in the control cabinet. Wherein, different kinds of components can produce different degree of heat when the work is operated. Components with larger heat generated during operation need to be timely radiated so as to prevent the heat from being timely radiated, so that the service life is shortened, or fire disaster is caused. Therefore, by arranging the heat dissipation device 100 on the control cabinet, the heat dissipation device 100 is installed close to the components needing heat dissipation, so that the components are subjected to cooling treatment and heat dissipation treatment in time, and the running stability and safety of the components are further ensured.
When there are a plurality of components in the control cabinet that need to dissipate heat, a plurality of groups of heat dissipation devices 100 may be provided, and each heat dissipation device 100 corresponds to an individual component. That is, in the present embodiment, the heat dissipation device 100 may be independently disposed according to actual situations, and the heat dissipation device 100 may be independently disposed around each component requiring heat dissipation, thereby ensuring the heat dissipation effect of the component. Each heat dissipating device 100 can independently operate without interference, thereby ensuring the heat dissipation effect of each component.
Specifically, the heat dissipating device 100 includes a cold air mechanism 1 and a hot air mechanism 2, the cold air mechanism 1 is adapted to deliver cold air into the control cabinet, and the hot air mechanism 2 is adapted to deliver heat in the control cabinet to the outside. As can be seen from the foregoing, the heat sink 100 is installed close to the components in the control cabinet that need to dissipate heat. Therefore, the cold air mechanism 1 is suitable for conveying cold air to components in the control cabinet; and in the same way, the hot air mechanism 2 conveys heat generated by components in the control cabinet to the outside.
In order to further ensure the heat dissipation effect, based on the fact that hot air floats upwards, cold air sinks away, the hot air mechanism 2 is arranged above the cold air mechanism 1 in the height direction of the control cabinet, and the cold air mechanism 1 can convey cold air flow to a part of a component needing heat dissipation to conduct heat dissipation and temperature reduction treatment; and the heat generated by the operation of the components is absorbed by the hot air mechanism 2 and is transmitted to the outside after rising, so that the temperature in the control cabinet is cooled.
Wherein, cold wind mechanism 1 includes cold wind generating component and cold wind conveying component 13 that cold wind generating component communicates. In the embodiment, the cold air generating component is arranged outside the control cabinet, so that cold air flow with proper temperature is formed; the cold air conveying component 13 is arranged in the control cabinet to convey the formed cold air flow to the parts needing heat dissipation.
Referring to fig. 3, 7 and 8, the cold air generating assembly includes an air inlet unit 11 and a cooling unit 12 connected to the air inlet unit 11, and air flows from the air inlet unit 11 into the cooling unit 12, and is cooled by the cooling unit 12 and then delivered to the cold air delivering assembly 13.
The air inlet unit 11 comprises an air inlet cover 111, a first filter 114 and a guide 112, wherein the first filter 114 is connected with the air inlet cover 111, the first filter 114 is arranged at the first opening, so that the first filter 114 filters air flow entering the air inlet cover 111 to prevent impurities from entering the air inlet unit 11, and the impurities enter the control cabinet through the air inlet unit 11, the refrigerating unit 12 and the cold air conveying unit, thereby avoiding the influence of the impurities on the operation of components in the control cabinet and ensuring the operation efficiency of the components in the control cabinet.
The guide member 112 is mounted on the outer side of the first filter member 114 and located at the first opening, and the guide member 112 is adapted to guide the fluid falling onto the air inlet cover 111 and/or the guide member 112 to move in a direction away from the first opening, so as to prevent the fluid from entering the air inlet cover 111 from the first opening. In this embodiment, the fluid is sewage, water droplets, or the like.
The guide 112 has a guide surface 1121, and the guide surface 1121 is disposed obliquely. The guide surface 1121 is inclined from top to bottom from the side close to the first filter 114 toward the side far from the first filter 114 in the height direction of the air intake cover 111. The purpose of this arrangement is that: when water drops fall on the air inlet cover 111 and/or the guide piece 112, the guide piece 112 guides the water drops to the position far away from the first opening, so that the water drops are effectively prevented from entering the air inlet cover 111 under the action of negative pressure, and then enter the control cabinet through the cold air mechanism 1, and the influence is caused on components in the control cabinet. The height direction of the air inlet cover 111 is parallel to the height direction of the control cabinet.
The air intake cover 111 has a top and a bottom disposed opposite to each other, and a first opening is disposed on the bottom, from which air flow can enter the air intake cover 111. In the present embodiment, the purpose of providing the first opening on the bottom of the air intake cover 111 is to: the refrigeration unit 12 has a second opening 1211, the second opening 1211 being adapted to dissipate heat generated by operation of the airflow generating member 123 of the refrigeration unit 12. In order to avoid the air flow sucked into the air inlet cover 111 being hot air flow, the first opening is arranged at the bottom of the air inlet cover 111, so that the refrigerating effect of the cold air mechanism 1 is further ensured.
In this embodiment, the air intake cover 111 has a horn shape. In the height direction of the air inlet cover 111, the top dimension of the horn-shaped air inlet cover 111 is smaller than the bottom dimension, so that more air flow can enter the air inlet cover 111.
In order to further ensure the air intake volume and the air intake efficiency of the air intake unit 11, the vortex is prevented from being generated in the horn-shaped air intake cover 111, the air intake unit 11 is provided with a vortex groove 113, and the vortex groove 113 is adapted to prevent the vortex from being formed in the air intake unit 11. In the present embodiment, the flow disturbing groove 113 is provided on the air intake cover 111 and/or the first filter member 114 and/or the guide member 112, and the flow disturbing groove 113 is provided near the first opening. That is, the air intake cover 111, the first filter 114, and the guide 112 may be provided with the flow disturbing grooves 113 at the same time, or one of the air intake cover 111, the first filter 114, and the guide 112 may be provided with the flow disturbing grooves 113, or both of the air intake cover 111, the first filter 114, and the guide 112 may be provided with the flow disturbing grooves 113 at the same time, which is not particularly limited herein, and may be determined according to the actual situation. In order to ensure the air intake efficiency and the air intake quantity, in the present embodiment, the air intake cover 111, the first filter 114 and the guide 112 are all provided with the flow disturbing grooves 113, and the flow disturbing grooves 113 on the air intake cover 111 and the guide 112 are respectively arranged in a one-to-one correspondence. Meanwhile, the turbulence grooves 113 on the guide member 112 and the turbulence grooves 113 of the first filter member 114 are arranged in a staggered manner, so that water drops are prevented from passing through the turbulence grooves 113 on the guide member 112, through the first filter member 114 and into the air inlet cover 111. Wherein, dislocation set means: there is a partial overlap or no overlap of the spoiler grooves 113 of the guide member 112 and the forward projection of the spoiler grooves 113 of the first filter member 114.
As can be seen from the foregoing, the guide surface 1121 of the guide 112 is inclined such that there is a space between the guide surface 1121 of the guide 112 and the first filter 114. In order to further ensure the air intake effect and the air intake quantity of the air intake unit 11, the air intake unit 11 further includes a first sealing member 117, and the first sealing member 117 is disposed between the outer side surface of the first filter member 114 and the inner side surface of the guide member 112, so as to prevent the air flow from entering the air intake cover 111 from the space to generate a split flow.
The refrigeration unit 12 includes a refrigeration housing 121 in communication with the air intake cover 111, an airflow generating member 123 disposed at an air intake of the refrigeration housing 121, and a refrigeration member 124 disposed in the refrigeration housing 121, and in this embodiment, the airflow generating member 123 is a fan and a driving motor connected to the fan. In other embodiments, the airflow generating member 123 may be the fan 214 directly, which is not limited herein, and may be according to practical situations.
The driving motor can drive the fan blade to rotate positively and reversely under different conditions. When the driving motor drives the fan blades to rotate forward, negative pressure can be generated in the air inlet cover 111, so that air flow flowing into the refrigerating unit 12 is generated. When the fan blades are driven by the driving motor to rotate reversely, air flow blowing to the first filter element 114 can be formed, and dust attached to the first filter element 114 is cleaned by the air flow, so that the air inlet efficiency and the refrigerating efficiency of the cold air module are guaranteed.
Referring to fig. 5, 6 and 8-10, the cooling member 124 includes a fixing frame body 1244 having a mounting cavity, a cooling grid 1241 mounted in the mounting cavity, cooling fins 1245 disposed outside the fixing frame body 1244, cooling fins 1243 disposed at two sides of the fixing frame body 1244 and covering the fixing frame body 1244, and a wind collecting cover 1246 covering the fixing frame body 1244, wherein a hollow portion is disposed at a position of the wind collecting cover 1246 corresponding to the cooling fins 1245, and the hollow portion can enable heat of the cooling fins 1245 to be transferred to the outside. In this embodiment, the cooling plate 1243 is a semiconductor cooling plate 1243, which uses the Peltier effect of semiconductor materials, and when direct current passes through a couple formed by connecting two different semiconductor materials in series, the two ends of the couple can absorb heat and release heat respectively, so as to achieve the purpose of cooling. Accordingly, the cooling unit 124 further includes a dc control driver 1247 connected to the cooling plate 1243, which is capable of generating a dc current flowing to the cooling plate 1243, so that the cooling plate 1243 generates a cooling effect. The dc control driver 1247 is controlled by the external control device 300 according to the actual situation, and is not particularly limited herein, and is determined according to the actual situation.
The heat dissipation fins 1245 are of a conventional structure, and are used for dissipating heat generated by the cooling fins 1243 to the outside, which is not described herein. The size of the hollowed-out portion is slightly larger than that of the radiating fin 1245, so that the radiating fin 1245 is exposed, radiating efficiency is improved, and refrigerating effect of the refrigerating unit 12 is ensured. And, the air flow generating member 123 is disposed at a side of the fixing frame body 1244 near the air inlet unit 11, thereby generating an air flow to the cooling member 124.
The air intake unit 11 forms an air flow to the cooling unit 12, which is formed into a cold air flow by the action of the cooling fins 1243 and transferred through the cooling grill 1241. Wherein, a part of the refrigerating member 124 is rounded at a side near the air flow generating member 123. In this embodiment, the portion of the refrigeration 124 is a refrigeration grill 1241. The side of the refrigeration grille 1241 near the airflow generating part 123 is rounded to reduce the wind resistance of the airflow, so that the airflow can flow more smoothly, and the refrigeration efficiency is further improved.
The refrigeration housing 121 is provided with a second opening 1211, the second opening 1211 being adapted to dissipate heat generated by operation of the air flow generator 123 and a portion of the refrigeration fins 1243.

The refrigeration unit 12 also includes a second filter 122 disposed at the second opening 1211, the second filter 122 being generally identical in structure and function to the first filter 114 and not described in further detail herein. In this embodiment, the first filter 114 and the second filter 122 may be sponge, hepa, etc., and the selection of materials or types may be performed according to practical situations, which is not specifically limited in this embodiment.
The first filter element 114 and the second filter element 122 are provided with warning elements adapted to mark the replacement cycle and/or the cleaning cycle of the first filter element 114 and the second filter element 122. In this embodiment, the warning member is a resistive filter element sensor, which is used to measure the principle that the resistance of the first filter member 114 and the second filter member 122 becomes low due to the increase of dust. When the resistance of the resistive cartridge sensor is lower than a preset value, the control device 300 controls the airflow generating member 123 to reverse. Alternatively, when the resistance of the resistive cartridge sensor is below a predetermined value, the control device 300 issues an alarm to alert the operator to replace the first filter member 114 and the second filter member 122.
As can be seen from the foregoing, the heat sink 100 and the control device 300 perform information interaction. Therefore, the cold air generating assembly further includes a first data transmission unit 125, and the first data transmission unit 125 can perform information interaction with the control device 300 through the communication device 200. In this embodiment, the first data transmission unit 125 is a bluetooth module, which is of a conventional structure, and is not specifically limited herein.
