Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production, and in particular to a matrix heat dissipation electrical cabinet used in a gypsum board production line. Background Art

[0002] Gypsum board production lines are usually composed of a variety of processing equipment and conveying equipment to form an equipment cluster. The power supply and control of these devices require corresponding electrical cabinets, which are usually installed directly near the production line for easy operation. However, the temperature of the gypsum board production line is usually high and dusty. Therefore, in order to improve the dustproof effect, the electrical cabinet will reduce the permeability of the internal and external airflow (such as adding dense filters, etc.), resulting in the temperature of the internal electrical components being easily operated in a high temperature environment due to the failure of heat dissipation to meet the requirements, thereby affecting its service life and operational safety.

[0003] Therefore, the electrical cabinets on the gypsum board production line are usually equipped with cabinet air conditioners to cool the air inside the cabinet. The cabinet air conditioners of such conventional electrical cabinets usually adopt a single-circulation airflow method in a top-mounted fixed area, that is, the internal unit of the cabinet air conditioner inhales hot air from the bottom to the top in the electrical cabinet for heat exchange, and discharges the cold air after heat exchange and cooling downward to reduce the air temperature in the electrical cabinet to achieve heat dissipation of electrical components. Although this method can achieve the effect of heat dissipation, since the airflow refrigerates and circulates in an area far away from the electrical components, the effective contact area between the circulating airflow and the electrical components is small (the outer layer of the circulating airflow generated by the cabinet air conditioner flows through the electrical cabinet and is easily blocked by larger electrical components), and the circulating airflow is also circulated for electrical components that do not exceed the threshold temperature, making it difficult for the cabinet air conditioner to quickly cool down the electrical components that are currently operating at a temperature exceeding the threshold. It is difficult to achieve rapid heat dissipation and wastes a lot of cooling capacity, resulting in lower energy efficiency.

[0004] Therefore, the existing electrical cabinets that use a single-cycle cabinet air conditioner with a fixed top area for heat dissipation have a slow heat dissipation rate and low energy efficiency because it is difficult to perform targeted heat dissipation on electrical components that exceed their threshold temperature. Summary of the invention

[0005] The object of the present invention is to provide a matrix heat dissipation electrical cabinet for a gypsum board production line to solve the technical problem in the prior art that it is difficult to perform targeted heat dissipation on electrical components that exceed their threshold temperature, resulting in slow heat dissipation rate and low energy efficiency.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a matrix heat dissipation electrical cabinet for a gypsum board production line, comprising:

[0045] A cabinet 1 is provided with a cabinet air conditioner, which includes an indoor unit 2 and an outdoor unit 3 which are respectively arranged inside and outside the cabinet 1, and a pipe assembly 4 is provided between the indoor unit 2 and the outdoor unit 3 to connect them. The pipe assembly 4 has an evaporation section and a condensation section which are respectively arranged inside the indoor unit 2 and the outdoor unit 3, so that the indoor unit 2 blows out cold air in the cabinet 1;

[0046] The indoor unit 2 includes a machine box 21, which is mounted on the inner wall of the cabinet door of the cabinet 1. The evaporation section of the pipeline assembly 4 is placed in the machine box 21, and both side walls of the machine box 21 are provided with air inlets 22 facing the inner wall of the cabinet 1, and a plurality of exhaust ports 23 distributed in a matrix are provided on the surface of the machine box 21, and each exhaust port 23 is provided with an independently working cooling fan 24;

[0047] The multiple cooling fans 24 are distributed in a matrix to divide the cabinet 1 into multiple rectangular cooling zones. Each cooling fan 24 automatically starts when the temperature of the corresponding cooling zone exceeds a threshold. At the same time, the outdoor unit 3 and the pipeline assembly 4 automatically adjust the working frequency according to the number of cooling fans 24 started, so as to dynamically adjust the cooling capacity of the evaporation section of the pipeline assembly 4.

[0048] Among them, the air outlet side of the cooling fan 24 is vertically directed toward the electrical components in the cabinet 1, so that it can directly blow the electrical components in the corresponding heat dissipation area to cool down and dissipate heat. After the cooling fan 24 generates negative pressure in the machine box 21, the air inlet 22 draws air from both sides of the cabinet 1 to form a two-way circulating airflow in the cabinet 1 that flows from the back wall of the cabinet 1 toward its two side walls for stable heat dissipation.

[0049] The electrical cabinet of this embodiment mainly installs the indoor unit 2 of the cabinet air conditioner on the cabinet door facing the electrical components, and the cooling fans 24 of the indoor unit 2 are distributed in a matrix on the machine box 21 to form multiple rectangular cooling areas in the cabinet 1. When the cooling area to which a certain electrical component in the cabinet 1 belongs is overheated, the cooling fans 24 in the corresponding area work to blow air to the electrical components to dissipate heat. At the same time, the cooling fans 24 generate negative pressure in the machine box 21, so that the air inlet 22 draws air from both sides of the cabinet 1, so that the cooling airflow blown onto the electrical components flows along the inner wall of the cabinet 1 to the air inlet 22 after heat exchange and enters the machine box 21 for circulation. That is, the cooling airflow can form a two-way circulation in the cabinet 1, avoiding the influence of the cooling effect of blowing air due to the disorderly airflow direction, thereby improving the stability of heat dissipation.

[0050] The multiple cooling fans 24 work independently to achieve targeted cooling of overheated electrical parts, and the number of cooling fans 24 in operation is determined according to the number of overheated cooling zones, and the machine 3 and the pipeline assembly 4 automatically adjust the working frequency according to the number of cooling fans 24 started, so as to dynamically adjust the cooling capacity of the evaporation section of the pipeline assembly 4, which can not only improve the cooling rate, but also improve the energy efficiency of the cooling work.

[0051] Compared with the existing electrical cabinet with single-circulation cabinet air conditioning for heat dissipation in a fixed top area, the electrical cabinet of this embodiment can arrange the cooling fans 24 in a matrix distribution on the machine box 21 and can generate negative pressure in the machine box 21, and the air inlet 22 on the side wall of the machine box 21 can draw air from both sides of the cabinet 1. Therefore, when the cooling fan 24 is blowing air directly at the electrical parts for heat dissipation, the airflow after heat exchange can enter the two air inlets 22 along both sides of the cabinet 1 to form a double-circulation heat dissipation airflow, thereby effectively reducing the turbulence caused by the recoil of the airflow and affecting the heat dissipation effect and the stability of the heat dissipation.

[0052] Of course, the start and stop of the cooling fan 24 needs to be determined according to the heating condition of the electrical components. Therefore, in order to enable each cooling fan 24 to work more accurately in the corresponding cooling area, the following preferred embodiments are provided.

[0053] like Figure 1 , Figure 2 As shown, a plurality of temperature detectors 5 are installed on the outer wall of the case 21, and the plurality of temperature detectors 5 are arranged between the plurality of cooling fans 24, so that each temperature detector 5 is linked to four surrounding cooling fans 24, and each temperature detector 5 has four detection areas corresponding to the four associated cooling fans 24;

[0054] When the temperature detector 5 detects that the temperature of a certain area rises above a threshold, the cooling fan 24 of the corresponding area automatically runs and blows air to dissipate heat in this area.

[0055] Specifically, the temperature detector 5 is arranged between the heat dissipation fans 24 distributed in a matrix, so that four heat dissipation fans 24 are arranged around one temperature detector 5, and each temperature detector 5 is used to detect the temperature of the electrical components in the heat dissipation area corresponding to the four heat dissipation fans 24;

[0056] Each temperature detector 5 is linked with four surrounding cooling fans 24, that is, when the temperature detector 5 detects that the temperature of the electrical components in a certain cooling zone exceeds a threshold, the controller built into the indoor unit 2 automatically controls the cooling fan 24 corresponding to the cooling zone to work;

[0057] Each cooling fan 24 has only one temperature detector 5 linked to it to avoid control confusion.

[0058] Since each temperature detector 5 needs to detect the temperature of electrical components in the four surrounding heat dissipation zones, it is required to cover a larger area, but it is also required to avoid detecting the temperature of electrical components in other heat dissipation zones to reduce the difficulty of data processing. Based on this, the following preferred embodiments are provided.

[0059] like Figure 2 As shown, the temperature detector 5 includes an infrared detector 51 and a light shield 52. The infrared detector 51 is installed on the surface of the machine box 21 to receive infrared radiation from the electrical components inside the cabinet 1 and generate a thermal image. The light shield 52 is installed on the surface of the machine box 21 and shields the infrared detector 51 to limit the detection range of the infrared detector 51.

[0060] The detection areas of the infrared detectors 51 are equal, and the detection surfaces of the infrared detectors 51 are aligned with the four cooling zones corresponding to the four surrounding cooling fans 24. The infrared detectors 51 are connected to the built-in controller of the indoor unit 2. The controller of the indoor unit 2 divides the thermal imaging image fed back by the detection surface of the infrared detector 51 into four areas corresponding to the four cooling zones.

[0061] Specifically, the infrared detector 51 is used to receive infrared radiation from objects within the field of view of the photosensitive side and convert the infrared radiation into an electrical signal. Then, the controller built into the indoor unit 21 can convert the electrical signal into a thermal image to reflect the temperature of the electrical components within the field of view (equivalent to the infrared thermal imager in the prior art);

[0062] The light-sensitive side field of view of the infrared detector 51 is partially shielded by the shading hood 52, so that the field of view of the infrared detector 51 is in a specific range and shape, so that it corresponds to the four surrounding heat dissipation zones, that is, the thermal imaging diagram of the four surrounding heat dissipation zones is displayed, and the built-in controller of the indoor unit 21 can divide the thermal imaging diagram into four parts to correspond to the four heat dissipation zones, so as to monitor the temperature of the electrical components in each heat dissipation zone in real time and dissipate the heat of the overheated electrical components in time.

[0063] According to the above embodiment, the airflow blown out by the cooling fan 24 is the air cooled and cooled in the indoor unit 21 through the evaporation section of the pipeline assembly 4, thereby ensuring the cooling effect of the cooling fan 24. Based on this, the following preferred embodiments are provided.

[0064] like Figure 1 , Figure 2 , Figure 3 As shown, the pipeline assembly 4 includes two evaporators 41 and a condenser 42. The two evaporators 41 are symmetrically installed inside the machine box 21 and respectively abut against the two air inlets 22. The two evaporators 41 cool the airflow sucked in by the two air inlets 22.

[0065] The condenser 42 is installed inside the external unit 3 . A liquid inlet manifold 43 and a liquid outlet manifold 44 are respectively installed on the two evaporators 41 , and main ends of the liquid inlet manifold 43 and the liquid outlet manifold 44 are both connected to the condenser 42 .

[0066] Specifically, the evaporator 41 and the condenser 42 are connected through the liquid inlet manifold 43 and the liquid outlet manifold 44 to form a refrigeration cycle, and the remaining components including the compressor, the expansion valve, etc. are located in the external unit 3, which belongs to conventional technical means and will not be described in detail;

[0067] Two evaporators 41 are used and are arranged at two air inlets 22 respectively. Therefore, when the machine box 21 draws air through the air inlet 22, the external hot air flow enters the machine box 21 and needs to exchange heat with the evaporator 41, so that the hot air flow is cooled to a cold air flow and is discharged by the cooling fan 24, which can quickly reduce the temperature of the electrical components and achieve a good heat dissipation effect.

[0068] Since the cooling fan 24 generates negative pressure in the machine box 21, the airflow entering the evaporator 41 tends to flow out from the side of the evaporator 41, resulting in the airflow heat exchange time being too short and it is difficult to meet the cooling requirements. Therefore, in order to allow the airflow to completely pass through the evaporator 41, the following preferred embodiments are provided.

[0069] like Figure 4 As shown, the evaporator 41 includes a plurality of heat exchange fins 411, and a clamping plate 412 is installed on both sides of the plurality of heat exchange fins 411. The two clamping plates 412 are fixed in the machine box 21 and fix the plurality of heat exchange fins 411 horizontally and equidistantly, so as to form a heat exchange flow channel 413 perpendicular to the air inlet 22 between two adjacent heat exchange fins 411;

[0070] The heat exchanger fins 411 are hollow structures, and pipe connectors 414 are provided at both ends of each heat exchanger fin 411 . The two pipe connectors 414 are respectively installed on the liquid inlet manifold 43 and the liquid outlet manifold 44 and connected to divert the refrigerant into multiple heat exchanger fins 414 .

[0071] Specifically, the two clamping plates 412 install the plurality of heat exchange fins 411 therebetween, so that the airflow can only flow from one end of the evaporator 41 to the other end, but cannot flow out from the middle. Therefore, the time for the airflow to flow in the evaporator 41 can be extended, thereby improving the cooling and heat exchange effect of the airflow.

[0072] The heat exchanger 411 adopts a hollow design, and each heat exchanger 411 has two pipe joints 414 to connect the liquid inlet manifold 43 and the liquid outlet manifold 44 respectively. That is, the multiple heat exchanger fins 411 are designed in parallel, and the liquid inlet manifold 43 diverts the refrigerant to each heat exchanger fin 411. Compared with the series structure, the cooling effect is more uniform.

[0073] Of course, in order to further enhance the cooling effect of the heat exchange plate 411 on the hot air flow, the following preferred embodiments are further provided.

[0074] like Figure 4 As shown, a plurality of fins 415 are disposed on the side walls of the heat exchanger 411, the fins 415 are disposed horizontally and perpendicular to the side walls of the heat exchanger 411, and the fins 415 are placed in the heat exchange flow channel 413;

[0075] The multiple fins 415 on two adjacent heat exchange plates 411 are arranged in a staggered manner so as to be inserted into the gap between the two adjacent fins 415 .

[0076] Specifically, fins 415 are provided on the surface of the heat exchanger 411, and the fins 415 are placed in the heat exchange channel 413 to increase the heat exchange area. The multiple fins 415 on two adjacent heat exchangers 411 are staggered to extend the fins 415 as much as possible, thereby further expanding the area of ​​the fins 415 and improving the heat exchange rate.

[0077] Of course, in order to avoid greater resistance to the airflow, the fins 415 are designed to be horizontal and vertical on the side walls of the heat exchanger 411, resulting in the contact surface between the fins 415 and the heat exchanger 411 being only the end side area of ​​the fins 415, resulting in a slower rate of refrigerant heat transfer from the heat exchanger 411 to the fins 415. Based on this, the following preferred embodiments are provided.

[0078] like Figure 4 As shown, a plurality of mounting openings 416 are provided on the side wall of the heat exchanger 411, one end of a plurality of fins 415 passes through the mounting openings 416 and is placed inside the heat exchanger 411, and the fins 415 and the mounting openings 416 are welded and sealed;

[0079] One end of the fin 415 located inside the heat exchange plate 411 is curled or bent.

[0080] Specifically, the fin 415 is inserted into the heat exchanger 411 through the mounting opening 416, so that the refrigerant in the heat exchanger 411 can directly contact part of the fin 415, thereby effectively increasing the contact area between the refrigerant and the fin 415 and improving the heat transfer rate. In addition, the bending or curving of the end of the fin 415 in the heat exchanger 411 can further increase the contact area between the fin 415 and the refrigerant, thereby further improving the heat transfer rate, so that the cooling rate of the hot air flow by the fin 415 is increased.

[0081] According to the above embodiment, the cooling fan 24 blows air directly towards the electrical components. After the airflow contacts the electrical components, there is partial backflow and collision with the subsequent airflow to generate turbulence. The turbulence will interfere with the cooling airflow generated by the cooling fan 24 and affect the cooling effect. In addition, the negative pressure generated by the air inlet 22 will also cause part of the airflow generated by the cooling fan 24 to be diverted thereto, resulting in a decrease in the actual cooling ratio of the cooling airflow, affecting the cooling effect. Based on this, the following preferred embodiments are provided.

[0082] like Figure 2 , Figure 5 As shown, wind shielding components 25 are provided on both side edges of the machine box 21, and the wind shielding components 25 extend to the outside of the electrical component installation area of ​​the cabinet 1. The wind shielding components 25 form a gap behind the electrical components of the cabinet 1 to block the airflow from the cooling fan 24 to the electrical components in the cabinet 1 from flowing to both sides, and guide the airflow blown by the cooling fan 24 to pass through the electrical components of the cabinet 1, enter the inner side wall of the cabinet 1 and the wind shielding components 25 from the rear thereof, and be sucked in by the air inlet 22;

[0083] The wind shielding assembly 25 can be retracted and unfolded so as to be automatically folded when the door of the cabinet body 1 is opened, and automatically unfolded after the door of the cabinet body 1 is closed.

[0084] Specifically, a wind shield assembly 25 is provided on both sides of the machine box 21. The wind shield assembly 25 can effectively separate the cabinet 1 to form a heat dissipation area (the area between the machine box 21 and the electrical components) and a circulation flow channel (the area from the rear of the electrical components to the side wall of the cabinet 1), thereby preventing the heat dissipation airflow generated by the cooling fan 24 from flowing directly to the air inlet 22 before reaching the electrical components. The heat dissipation airflow is thereby guided to flow directly along the surface of the electrical components to the rear after impacting the electrical components and to flow from the side wall of the cabinet 1 to the air inlet 22. This can not only enable the heat dissipation airflow to form a directional circulation to reduce the influence of turbulence and diversion, but also enable the heat dissipation airflow to cover the surface of the electrical components to increase the heat dissipation area, thereby quickly reducing the temperature of the electrical components.

[0085] Of course, in order to avoid the wind shielding assembly 25 from blocking interference when opening and closing the cabinet door, the wind shielding assembly 25 adopts a retractable structure, as follows:

[0086] like Figure 2 , Figure 5As shown, the windshield assembly 25 includes a windshield roll bag 251, which is fixed at the edge of the machine box 21. A gas nozzle 252 is provided on one side of the windshield roll bag 251 close to the machine box 21. The windshield roll bag 251 is unrolled and extended after the internal pressure is increased, and is reeled and shortened after the internal pressure is reduced.

[0087] An air pump 253 is provided in the machine box 21, and an air guide manifold 254 is provided on the air pump 253. The air guide manifold 254 is connected to two air nozzles 252 so as to inflate air into the windshield roll bag 251 during forward rotation, or to extract air from the windshield roll bag 251 during reverse rotation.

[0088] Among them, the air pump 253 is directly connected to the air nozzles 252 on the two windshield roll bags 251 through the air guide manifold 254, so that the retraction and expansion of the windshield roll bags 251 can be synchronously controlled. The air pump 253 is controlled by a forward and reversible motor, so that it inflates the windshield roll bag 251 when it rotates forward, and draws air from the windshield roll bag 251 when it rotates reversely.

[0089] The cabinet door of the cabinet body 1 is opened with a switch component, that is, the cabinet door will feedback a switch signal to the controller in the indoor unit 2 when it is locked and unlocked, so as to facilitate the controller to control the retraction and extension of the windproof roll bag 251 when the cabinet door is opened and closed.

[0091] like Figure 1 , Figure 6 As shown, the main ends of the liquid inlet manifold 43 and the liquid outlet manifold 44 are both provided with hoses 45, and the liquid inlet manifold 43 and the liquid outlet manifold 44 extend into the external unit 3 through the hoses 45 to connect with the condenser 42, and the hoses 45 are arranged at the door hinge of the cabinet 1 to bend to adapt to the movement of the cabinet door of the cabinet 1.

[0092] Specifically, the connecting sections of the liquid inlet manifold 43 and the liquid outlet manifold 44 and the condenser 42 are connected by a hose 45, and the hose 45 is arranged at the door hinge of the cabinet 1, so that when the cabinet door of the cabinet 1 is opened and closed, the hose 45 can bend freely without being affected.

[0093] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
