Description

Technical Field

[0001] This invention belongs to the field of air conditioning equipment, and more specifically, relates to an air-cooled heat dissipation device and an air conditioning unit. Background Technology

[0002] The electrical components of air conditioning products are all housed within the product's electrical box, which presents a problem of component overheating and potential damage. Current solutions fall into two categories: one is refrigerant cooling, where refrigerant pipes are installed within a radiator close to the module, using the refrigerant's low temperature to lower the module's temperature to a safe level. The other is using airflow to conduct heat from the radiator to the air, lowering the internal temperature of the electrical box. Both methods have advantages and disadvantages. Refrigerant cooling is more efficient and provides better heat dissipation, but its application is limited, mainly to the controller module. Air cooling is less efficient than refrigerant cooling but has a wider range of applications, working throughout the entire electrical box. However, the moisture content in the air cannot be accurately assessed, resulting in poor sealing and a potential risk of condensation.

[0003] Therefore, how to provide an air-cooled heat dissipation solution to improve the condensation problem is an urgent issue that needs to be addressed in the industry. Summary of the Invention

[0004] The purpose of this invention is to provide an air-cooled heat dissipation device and an air conditioning unit to solve the problem of condensation that occurs in existing air-cooled heat dissipation solutions.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an air-cooled heat dissipation device, comprising:

[0006] Heating components;

[0007] A humidifying component is located below the heating component;

[0008] An air duct baffle is rotatably disposed between the heating element and the humidifying element;

[0009] The control module is electrically connected to the heating element, the humidifying element, and the air duct baffle, respectively. When the control module determines that the temperature inside the heating element has reached the heat dissipation temperature, it shuts off the humidifying element and simultaneously controls the air duct baffle to rotate so that the airflow passing through the humidifying element flows to the heating element.

[0010] Furthermore, it also includes an air duct cover plate, which is disposed on the humidifying component, and the air duct cover plate has an air outlet for the airflow to pass through.

[0011] Furthermore, one end of the air duct baffle is fixedly connected to the heating element, the other end of the air duct baffle is detachably connected to the air duct cover plate, and the other end of the air duct baffle can rotate relative to the heating element.

[0012] Furthermore, the air duct baffle is a louver.

[0013] Furthermore, a temperature sensing device is provided above the heating element, and the temperature sensing device is electrically connected to the control module.

[0014] Furthermore, a heat dissipation vent is provided below the heating element for the airflow to enter the heating element.

[0015] Based on the same inventive concept, the present invention also provides an air conditioning unit, including a unit frame and a wind-cooled heat dissipation device as described above, wherein the wind-cooled heat dissipation device is disposed within the unit frame.

[0016] Furthermore, it also includes a fan assembly, which is mounted on the upper part of the unit frame and located on one side of the heat-generating component.

[0017] Furthermore, it also includes a heat exchanger located below the fan component.

[0018] Furthermore, there are two heat exchangers, namely a first heat exchanger and a second heat exchanger. The first heat exchanger is horizontally installed in the middle of the unit frame, and the second heat exchanger is inclinedly installed in the lower part of the unit frame.

[0019] The beneficial effects of the air-cooled heat dissipation device and air conditioning unit provided by the present invention are as follows: Compared with the prior art, the present invention adjusts the position of the air duct baffle according to the internal temperature of the heat-generating component to perform air-cooled heat dissipation for the heat-generating component, while turning off the humidification component to ensure that dry cold air flows to the heat-generating component, thereby achieving cooling inside the heat-generating component and preventing condensation.

[0034] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] The electrical components of air conditioning products are all housed within the product's electrical box, which presents a problem of component overheating and potential damage. Current solutions fall into two categories: one is refrigerant cooling, where refrigerant pipes are installed within a radiator close to the module, using the refrigerant's low temperature to lower the module's temperature to a safe level. The other is using airflow to conduct heat from the radiator to the air, lowering the internal temperature of the electrical box. Both methods have advantages and disadvantages. Refrigerant cooling is more efficient and provides better heat dissipation, but its application is limited, mainly to the controller module. Air cooling is less efficient than refrigerant cooling but has a wider range of applications, working throughout the entire electrical box. However, the moisture content in the air cannot be accurately assessed, resulting in poor sealing and a potential risk of condensation.

[0040] In response to this, the present invention provides an air-cooled heat dissipation device and an air conditioning unit, which can provide air-cooled heat dissipation for the heat-generating components of the air conditioning unit and also solves the problem of condensation caused by using air-cooled heat dissipation.

[0041] Please refer to the following: Figure 1 , Figure 2 The air conditioning unit 100 provided by the present invention includes a unit frame 1 and an air-cooled heat dissipation device disposed in the unit frame 1.

[0042] For ease of understanding, the following directions are explained: the height of the unit frame 1 is the up-down direction, the length of the unit frame 1 is the left-right direction, and the width of the unit frame 1 is the front-back direction.

[0043] The unit frame 1 includes four vertically arranged columns. A top-level frame is installed at the upper end of each column, and a middle-level frame is installed in the middle of the unit frame 1. An air-cooled heat dissipation device is installed inside the unit frame 1, primarily located between the top-level and middle-level frames.

[0044] The air-cooled heat dissipation device mainly includes a heating element, a humidifying element, an air duct baffle 4, and a control module. The location of the control module is not limited. The control module is electrically connected to the heating element, the humidifying element, and the air duct baffle 4. The control module can obtain the internal temperature of the heating element in real time, turn the humidifier 21 on or off, and control the rotation of the air duct baffle 4.

[0045] The heat-generating component can be the electrical component that generates the most heat within the air conditioning unit 100. Typically, the electrical components of an air conditioning product are concentrated within the electrical box 51, and this heat-generating component can be the electrical box component 5. The electrical box component 5 is shaped like a box, and it is equipped with a temperature sensing device 52. Because hot air has a lower density, the hot air inside the electrical box 51 concentrates at the top; therefore, the temperature sensing device 52 is installed at the top of the electrical box 51 to measure the temperature inside. The electrical box 51 has heat dissipation vents 53 at both the top and bottom. The heat dissipation vent 53 at the bottom allows external airflow to enter the electrical box 51, while the heat dissipation vent 53 at the top allows airflow to exit through the interior of the electrical box 51.

[0046] The humidification component includes a humidifier mounting bracket 2 and a humidifier 21. The humidifier mounting bracket 2 is installed on the intermediate frame, and the humidifier 21 is fixed inside the humidifier mounting bracket 2. According to the customer's requirements for constant temperature and humidity, the air conditioning unit 100 adds a humidifier 21 inside the humidifier mounting bracket 2 to ensure that the air blown out by the air conditioning unit 100 has a constant humidity.

[0047] The air duct baffle 4 is positioned between the heating element and the humidifying element, and its position is adjusted through logic control and temperature detection. The structure of the air duct baffle 4 can vary; for example, it can be a louver.

[0048] It should be noted that the air duct baffle 4 can be set to be directly connected to the heating element, or the air duct baffle 4 can be set not to be connected to the heating element, as long as the air duct baffle 4 can be rotated between the heating element and the humidifying element to change the direction of the airflow passing through the humidifying element.

[0049] As an example, the air duct baffle 4 is installed on the unit frame 1 and suspended between the heating component and the humidifying component. The installation method of the air duct baffle 4 is similar to the structure of a rotating shaft, and the air duct baffle 4 can be rotated by a motor.

[0050] As another example, the air duct baffle 4 includes a first end and a second end that are disposed opposite to each other. The first end of the air duct baffle 4 is fixedly connected to the heating element, and the second end of the air duct baffle 4 can rotate around the heating element.

[0051] The air-cooled heat dissipation device also includes an air duct cover plate 3, which is mounted on the unit frame 1 and is fixed in place. The air duct cover plate 3 is located on the humidification component and is mainly used as an air outlet in the direction of the humidifier 21 (regardless of whether the humidifier 21 is working). The air duct cover plate 3 has an air outlet for airflow passing through the humidification component.

[0052] As another example, one end of the air duct baffle 4 is fixedly connected to the heating element, and the other end of the air duct baffle 4 is detachably connected to the air duct upper cover plate 3. After the air duct baffle 4 is rotated, the end of the air duct baffle 4 will be fixedly connected to the air duct upper cover plate 3 by a snap-fit. When rotation is required, the snap-fit ​​will be released, and the air duct baffle 4 will rotate around the heating element.

[0053] The air conditioning unit 100 also includes a fan assembly 6 and a heat exchanger 7. The fan assembly 6 is mounted on the upper part of the unit frame 1 and is located on one side of the heat-generating components. The heat exchanger 7 is located below the fan assembly 6. There are two heat exchangers 7: a first heat exchanger 71 and a second heat exchanger 72. The first heat exchanger 71 is horizontally mounted in the middle of the unit frame 1, and the second heat exchanger 72 is obliquely mounted at the lower part of the unit frame 1.

[0054] Understandably, the inclusion of two heat exchangers 7 is primarily based on structural and system considerations. Structurally, the air conditioning unit 100 has a large height-to-width ratio, posing a potential stability risk. Adding a transverse heat exchanger 7 (i.e., the first heat exchanger 71) in the middle section improves the overall strength of the unit and reduces the risk of deformation. System-wise, when the customer requires a lower indoor humidity and a higher ambient temperature, to meet the humidity requirement, the air temperature will be lower than the required ambient temperature after passing through the inclined heat exchanger 7 (i.e., the second heat exchanger 72). At this point, the transverse heat exchanger 7 (i.e., the first heat exchanger 71) raises the air temperature through heating, achieving both low humidity and high temperature, thus improving the unit's temperature control accuracy.

[0055] To facilitate understanding, the following will be combined with Figures 1 to 11 This paper introduces a more detailed air conditioning unit 100.

[0056] like Figure 1 and Figure 6 As shown, the air conditioning unit 100 is an air-suction type unit. The air conditioning unit 100 includes a unit frame 1 and an air-cooled heat dissipation device, a fan component 6 and a heat exchanger 7 installed in the unit frame 1.

[0057] The air-cooled heat dissipation device includes an electrical box component 5, a humidifier mounting bracket 2, a humidifier 21, an air duct cover plate 3, and an air duct baffle 4. The electrical box component 5 and the fan component 6 are installed on the upper part of the unit frame 1. The fan component 6 is located on one side of the electrical box component 5. One end of the air duct baffle 4 is fixedly connected to the side of the electrical box component 5 near the fan component 6, and the other end of the air duct baffle 4 is detachably connected to the air duct cover plate 3. Simultaneously, the other end of the air duct baffle 4 can rotate around the electrical box component 5. When the air duct baffle 4 is static, the other end of the air duct baffle 4 is fixedly connected to the air duct cover plate 3 with a snap-fit ​​mechanism. When the air duct baffle 4 needs to rotate, it disengages from the snap-fit ​​mechanism, allowing it to rotate around the electrical box component 5. The heat exchanger 7 includes a first heat exchanger 71 and a second heat exchanger 72. The first heat exchanger 71 is horizontally installed in the middle of the unit frame 1, and is located on one side of the air duct cover plate 3. The second heat exchanger 72 is installed at an angle on the lower part of the unit frame 1.

[0058] The air conditioning unit 100 includes a heat exchange duct and a heat dissipation duct, the latter being a duct formed within the heat exchange duct. The heat exchange duct is formed by a heat exchanger 7, an electrical box 51, a duct baffle 4, and a housing, all sealed together. In this embodiment, the housing on the unit frame 1 is hidden to demonstrate the internal structure. The heat dissipation duct is formed by a humidifier 21 mounting plate, a duct cover plate 3, and a duct baffle 4.

[0059] This embodiment also provides two specific structures for the electrical box component 5. For example... Figure 7As shown, the electrical box component 5 includes an electrical box 51. A temperature sensing device 52 is installed on the top of the electrical box 51. Two heat dissipation vents 53 are opened on the bottom of the electrical box 51, and a heat dissipation vent 53 is also opened on the top of the electrical box 51 (not shown in the figure). Figures 8 to 11 As shown, the electrical box component 5 includes an electrical box 51. Two heat dissipation vents 53 are opened at the bottom of the electrical box 51, and one heat dissipation vent 53 is opened at the top of the electrical box 51. A temperature sensing device 52 is installed on the top of the electrical box 51 next to the heat dissipation vent 53.

[0060] like Figure 3 and Figure 4 As shown, the air duct baffle 4 adopts a louver structure. Due to the orientation of the louvers, the opening direction needs to face the fan. The overall airflow is directed towards the fan component 6, and there is very little possibility of backflow entering the electrical box 51 through the air duct baffle 4.

[0061] Please see Figure 1 , Figure 3 and Figure 5 , Figure 1 This is a schematic diagram of the unit's normal operation. Figure 3 This is a schematic diagram of the duct damper under normal operating conditions of the unit. Figure 5 This is a diagram showing the airflow direction under normal operating conditions of the unit.

[0062] The lower part of the unit frame 1 is equipped with an air inlet. Under normal operating conditions, the air entering the unit frame 1 can be divided into two airflows, one of which (such as...) Figure 5 As shown in Figure B, the airflow passes through the second heat exchanger 72 and the first heat exchanger 71 in sequence before flowing to the fan component 6. Another part of the airflow (such as...) Figure 5 (As shown in A) After passing through the humidifier 21, the fluid flows to the fan component 6.

[0063] Please see Figure 2 , Figure 4 and Figure 6 , Figure 2 This is a schematic diagram of the heat dissipation of the unit's electrical box. Figure 4 This is a schematic diagram of the air duct baffle when the electrical box is in a heat dissipation state. Figure 6 This is a diagram showing the airflow direction for heat dissipation from the unit's electrical box.

[0064] The lower part of the unit frame 1 is equipped with an air inlet. When the unit electrical box 51 is in heat dissipation mode, the air entering the unit frame 1 can be divided into two parts of airflow, one part of which is airflow (such as...) Figure 6 As shown in Figure B, the airflow passes through the second heat exchanger 72 and the first heat exchanger 71 in sequence before flowing to the fan component 6. Another part of the airflow (such as...) Figure 6 (As shown in A) After passing through the humidifier 21 and the electrical box component 5, it flows to the fan component 6.

[0065] The control method for the air-cooled heat dissipation device is as follows: Based on the customer's requirements for constant temperature and humidity, a humidifier 21 is added to the mounting plate of the humidifier 21 to ensure that the air blown out by the unit has a constant humidity. When the temperature sensing device 52 measures that the ambient temperature inside the electrical box 51 exceeds 80% of the safe temperature of the electrical components during unit operation, the control module controls the air duct baffle 4 to... Figure 1 Rotate the upper cover plate 3 of the central duct to position 3 Figure 2 At position 3 on the upper cover of the air duct, the humidifier 21 is simultaneously turned off, creating a low humidity environment in the room (which is definitely low temperature relative to the electrical box 51). The low-temperature air enters the heat dissipation duct, and a small portion of the dry, cold air enters the electrical box 51 through the heat dissipation vent 53 to exchange heat with the hot air inside the electrical box 51, causing the temperature inside the electrical box 51 to drop. When the temperature sensor 52 detects that the temperature has dropped to 40% of the safe temperature, the unit returns to normal. Figure 1 If the temperature continues to exceed 80% of the safe operating temperature, the above process is repeated to cool the inside of the electrical box 51, thus achieving air cooling for the electrical box 51 while avoiding condensation.

[0066] The air-cooled heat dissipation device and air conditioning unit provided by the present invention can automatically adjust the position of the air duct baffle according to the internal temperature of the heat-generating component to perform air-cooled heat dissipation for the heat-generating component, while turning off the humidification component to ensure that dry cold air flows to the heat-generating component, thereby achieving cooling inside the heat-generating component and preventing condensation.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
