Description

Technical Field

[0001] This application relates to the field of photovoltaic solar cell technology, and in particular to a chassis security door and a chassis. Background Technology

[0002] Currently, passivated contact cells remain one of the mainstream technologies for solar cells. Their diffusion, oxidation, and annealing processes all involve high temperatures. Excessive temperature inside the chassis can lead to longer cooling times for the quartz boat and silicon wafer in the storage compartment, affecting work efficiency.

[0003] In existing technologies, heat dissipation is achieved by drilling holes in the door panel of the chassis. This allows air inside the chassis to enter the workshop through the holes in the safety door, dissipating heat into the workshop and achieving a certain cooling effect, thereby accelerating the cooling of the quartz boat and silicon wafer inside the chassis.

[0004] However, dissipating heat into the workshop through the holes in the safety door will raise the temperature inside the workshop. This will not only transfer a large amount of heat into the workshop, affecting the comfort of the operators, but also, when there are multiple chassis in the workshop, the distance between the chassis becomes smaller, making it easy for convection to form between the chassis, causing them to affect each other and significantly reducing heat dissipation efficiency. Utility Model Content

[0005] This application discloses a chassis safety door that allows air inside the chassis to enter the heat dissipation chamber and then enter the heat dissipation system. This directly carries the heat inside the chassis into the heat dissipation system, which then discharges it outdoors. This not only prevents a large amount of heat from being transferred to the production workshop and affecting the working environment, but also meets the need for rapid heat dissipation, reduces the heat dissipation cycle, improves production efficiency, and avoids mutual interference between chassis.

[0006] To achieve the above objectives, according to the first aspect disclosed in this application, a chassis security door is provided, comprising:

[0009] The inner door panel has a through hole, the air inlet end of which is used to communicate with the interior of the chassis, and the air outlet end of which is connected to the heat exhaust chamber, so that the air of the chassis can enter the heat exhaust chamber through the through hole and then enter the heat exhaust system through the heat exhaust hole.

[0010] As an optional implementation, an exhaust fan is provided at the top of the heat dissipation chamber, and the exhaust fan is used to exhaust the air in the heat dissipation chamber to the heat dissipation hole.

[0015] Alternatively, the axial fan may be located on the side of the inner door panel facing the outer door panel, with the air inlet of the axial fan corresponding to the through hole.

[0016] As an optional implementation, the suction fan is a centrifugal fan;

[0017] The centrifugal fan is mounted on the outer door panel;

[0018] The centrifugal fan is located on the side of the outer door panel facing the inner door panel, with the air inlet of the centrifugal fan facing the through hole and the air outlet of the centrifugal fan facing the heat exhaust hole.

[0019] As an optional implementation, a flow guide channel is provided in the heat exhaust chamber. The flow guide channel has a main pipe and an air inlet pipe connected to the main pipe. The air inlet pipe corresponds one-to-one with the through hole. The air inlet end of each air inlet pipe is connected to the corresponding through hole. The air outlet end of the main pipe is connected to the heat exhaust hole.

[0020] As an optional implementation, a blower fan is provided in the main duct, which drives the air in the guide channel to flow from the air inlet end of the air inlet pipe to the air outlet end of the main duct.

The heat is then discharged outdoors through the heat dissipation system. This not only prevents a large amount of heat from being transferred to the production workshop, causing the working environment temperature inside the workshop to rise and affecting the comfort of the personnel inside the workshop, but also prevents convection interference between multiple chassis from affecting the stability and heat dissipation efficiency of the chassis. It can also meet the need for rapid heat dissipation, shorten the heat dissipation cycle, and improve production efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Unless otherwise stated, "a plurality of" means two or more.

[0045] In photovoltaic solar cell production, passivated contact cells remain one of the mainstream technologies, and their diffusion, oxidation, and annealing processes all involve high temperatures.

[0046] The diffusion process typically involves diffusing a dopant source (such as boron or phosphorus) through an ultrathin silicon oxide layer into a silicon substrate to achieve the desired doping concentration distribution. High temperatures are necessary in this process because they promote the diffusion rate of dopant atoms, resulting in more uniform and deeper doping. The temperature and time of diffusion need to be precisely controlled to ensure the formation of the ideal doping concentration and distribution while avoiding unnecessary damage to the silicon substrate.

[0047] The oxidation process is used to grow an ultrathin silicon oxide layer on a silicon substrate. This silicon oxide layer not only passivates surface defects on the crystalline silicon substrate but also acts as a tunneling layer, allowing charge carriers to transport through the tunneling effect. The oxidation process is typically performed using methods such as thermal oxidation, chemical oxidation, or plasma-assisted oxidation. In these methods, high temperatures can accelerate the oxidation reaction, increasing the growth rate and quality of the oxide layer. Simultaneously, high temperatures can also help remove defects and impurities from the oxide layer, improving its passivation effect.

[0048] The annealing process is used to crystallize the deposited doped silicon thin layer and optimize its performance. High temperature is essential in this process because it promotes the crystallization and activation of the doped silicon thin layer, improving parameters such as carrier transport performance and contact resistance. The annealing temperature and time need to be precisely controlled to ensure that the doped silicon thin layer can fully crystallize and achieve optimal performance, while avoiding damage to the battery structure.

[0049] High-temperature treatment plays a crucial role in the fabrication of passivated batteries, but it can also bring some adverse effects. For example, excessively high temperatures can lead to damage to the silicon oxide film, excessive diffusion of the doped silicon layer, and deformation of the metal electrode. Therefore, precise control of the temperature and time of high-temperature treatment is necessary during the fabrication process to ensure the performance and stability of the battery.

[0050] Therefore, it is often necessary to place the quartz boat and silicon wafers inside the chassis for cooling, and the duration of each cooling process directly affects production efficiency.

[0051] In existing technologies, heat dissipation is required for the chassis to allow the quartz boat and silicon wafer inside to cool down more quickly. Since the chassis needs to close its security door after the quartz boat and silicon wafer are installed inside to protect the stored items, existing chassis, while retaining the protective function of the security door, will be modified to improve heat dissipation by drilling holes in the security door to allow the air inside the chassis to be the same as that in the workshop, so that the heat inside the chassis can be dissipated into the workshop, achieving a certain heat dissipation effect.

[0052] Based on this, this application embodiment also provides a chassis safety door, which allows air inside the chassis to enter the heat dissipation chamber 1 inside the door 100, and then enter the heat dissipation system through the heat dissipation chamber 1, directly carrying the heat inside the chassis into the heat dissipation system, and dissipating it outdoors through the heat dissipation system. This not only avoids a large amount of heat being transferred to the production workshop and affecting the working environment inside the workshop, but also meets the need for rapid heat dissipation, shortens the heat dissipation cycle, improves production efficiency, and avoids mutual interference between chassis.

[0053] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0054] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a door body with an axial fan located on the side of the inner door panel facing away from the outer door panel, as disclosed in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a door body with an axial fan located on the side of the inner door panel facing the outer door panel, as disclosed in an embodiment of this application. Figure 3 This is a cross-sectional structural diagram of the door body disclosed in an embodiment of this application. This application discloses a chassis safety door, including: a door body 100, the interior of which has a heat dissipation chamber 1, the heat dissipation chamber 1 having a heat dissipation hole 11 for connecting the heat dissipation chamber 1 to a heat dissipation system; the door body 100 includes: an inner door panel 2 and an outer door panel 3 arranged along its thickness direction; the inner door panel 2 has a through hole 21, the air inlet end of the through hole 21 for communicating with the interior of the chassis, and the air outlet end of the through hole 21 for communicating with the heat dissipation chamber 1, so that air from the chassis can enter the heat dissipation chamber 1 through the through hole 21 and then enter the heat dissipation system through the heat dissipation hole 11.

[0055] Specifically, the door 100 can be a rectangular door, the size of which corresponds to the opening of the corresponding chassis. After storing items, the door 100 can close the chassis, protecting the stored items inside. The door 100 can have a certain thickness, with a cavity inside forming a heat dissipation chamber 1. The inner door panel 2 and the outer door panel 3 can be two panels of the same size and shape, arranged along the thickness direction of the door 100, located on both sides of the heat dissipation chamber 1 along the thickness direction of the door 100. The inner door panel 2 can be made of metal, which can better transfer heat, while the outer door panel 3 can be made of heat insulation material, such as foam glass or glass wool, which can provide a certain degree of heat insulation and reduce the heat transferred from the heat dissipation chamber 1 to the workshop through the outer door panel 3.

[0056] The inner door panel 2 is provided with a through hole 21. The through hole 21 can be a circular hole or a rectangular hole, and the shape is not limited. There can be multiple through holes 21. For a more aesthetically pleasing appearance, they can be arranged in an array. When the door 100 closes the chassis, the through hole 21 can connect the internal space of the chassis with the heat dissipation chamber 1, allowing air inside the chassis to enter the heat dissipation chamber 1.

[0057] The heat dissipation system can be a type of hot air handling equipment within a workshop. It includes a fan and ductwork, with the fan installed inside the ductwork to drive airflow. The ductwork connects the inside and outside of the workshop. The heat dissipation system expels hot air from the workshop to the outdoors, cooling the equipment inside. An additional heat dissipation duct can be added, connecting to the heat dissipation port 11 of the heat dissipation chamber 1. This allows air from inside the chassis to enter the heat dissipation chamber 1 through the through-hole 21, then enter the heat dissipation system through the heat dissipation port 11, and finally be exhausted outdoors. This not only expels hot air from the chassis to the outdoors, preventing a large amount of heat from being transferred into the workshop and affecting the working environment of the workers, but also prevents heat flow from interfering with each other when multiple chassis are placed close together, avoiding convection between chassis and preventing significant reduction in heat dissipation efficiency.

[0058] The thickness direction of the door 100 is the direction of the door 100 relative to the inside and outside of the chassis when the door 100 is fitted with the chassis and the chassis is closed.

[0059] According to the embodiment of this utility model, the chassis safety door allows air inside the chassis to enter the heat dissipation chamber 1 through the through hole 21 on the inner door panel 2, and then enter the heat dissipation system through the heat dissipation hole 11. This directly carries the heat inside the chassis into the heat dissipation system, which then directly discharges it outdoors. This not only prevents a large amount of heat from being transferred to the production workshop, causing the working environment temperature inside the workshop to rise and affecting the comfort of the personnel inside the workshop, but also prevents convection interference between multiple chassis from affecting the stability and heat dissipation efficiency of the chassis. It also meets the need for rapid heat dissipation, shortens the heat dissipation cycle, and improves production efficiency.

[0060] In some embodiments, an exhaust fan 4 is provided on the top of the heat dissipation chamber 1, and the exhaust fan 4 is used to exhaust the air in the heat dissipation chamber 1 to the heat dissipation hole 11.

[0061] Specifically, the exhaust fan 4 can be an axial fan, which can be installed at the top of the heat dissipation chamber 1. The axial fan can be located inside the heat dissipation chamber 1 with its air outlet corresponding to the heat dissipation hole 11, or it can be located outside the heat dissipation chamber 1 with its air inlet corresponding to the heat dissipation hole 11. By using the exhaust fan, the air in the heat dissipation chamber 1 can flow into the heat dissipation system from the heat dissipation hole 11 more quickly, and the heat in the heat dissipation chamber 1 can be removed more quickly, thereby improving the heat dissipation effect.

[0062] In some embodiments, the heat dissipation chamber 1 is provided with an air intake fan 5, which is used to draw air from inside the chassis into the heat dissipation chamber 1.

[0063] Specifically, the suction fan 5 can be an axial fan or a centrifugal fan. The suction fan 5 can make the air inside the chassis enter the heat dissipation chamber 1 more quickly, which can remove the heat inside the chassis more quickly and improve the heat dissipation effect.

[0064] Reference Figure 3 The number of through holes 21 can be greater than that of the suction fan 5, but each suction fan 5 corresponds to at least one through hole 21, so that the suction fan 5 can accelerate the air flow rate at the corresponding through hole 21, so that the air in the chassis 200 can enter the heat dissipation chamber 1 more quickly from the through hole 21.

[0065] In some embodiments, the suction fan 5 is an axial flow fan;

[0066] An axial fan is installed on the inner door panel 2, with the air inlet and outlet of the axial fan positioned opposite each other along the thickness direction of the door body 100.

[0067] Among them, reference Figure 1 The axial fan is located on the side of the inner door panel 2 facing away from the outer door panel 3, and the air outlet of the axial fan corresponds to the through hole 21.

[0068] Or refer to Figure 2 The axial fan is located on the side of the inner door panel 2 facing the outer door panel 3, and the air inlet of the axial fan corresponds to the through hole 21.

[0069] Specifically, the suction fan can be a type of axial fan, which is a fan device that uses blades to generate airflow in the axial direction. Its working principle is to generate axial airflow by rotating blades, drawing gas into the fan from the inlet and then expelling it from the outlet. When the motor starts, it drives the blades to rotate, and the airflow generated by the blades forces the gas to move along the axial direction. The pressure difference generated by this airflow drives the gas through the fan and is discharged to the target location. The axial fan can accelerate the speed at which air from inside the chassis enters the heat dissipation chamber 1, thereby improving heat dissipation efficiency.

[0070] In some embodiments, the suction fan 5 is a centrifugal fan;

[0071] The centrifugal fan is mounted on the outer door panel 3;

[0072] The centrifugal fan is located on the side of the outer door panel 3 facing the inner door panel 2. The air inlet of the centrifugal fan faces the through hole 21, and the air outlet of the centrifugal fan faces the heat exhaust hole 11.

[0073] Specifically, the working principle of a centrifugal fan is based on Newton's second law and the effect of centrifugal force. When the motor drives the impeller to rotate, the blades on the impeller are subjected to centrifugal force, causing the gas to accelerate along the curved path of the blades. Subsequently, the gas is sent to the outlet, generating airflow and forming airflow pressure. The air inlet of a centrifugal fan is usually located in the axial direction of the fan, while the air outlet is located in the radial direction of the fan, which can achieve the function of airflow deflection. The centrifugal fan can accelerate the speed at which air inside the casing enters the heat dissipation chamber 1, improving heat dissipation efficiency.

[0074] In some embodiments, a flow channel is provided in the heat dissipation chamber 1. The flow channel has a main pipe and an air inlet pipe connected to the main pipe. The air inlet pipe corresponds one-to-one with the through hole 21. The air inlet end of each air inlet pipe is connected to the corresponding through hole 21. The air outlet end of the main pipe is connected to the heat dissipation hole 11.

[0075] Specifically, a flow channel can be set in the heat dissipation chamber 1, and the air intake pipe is connected to the corresponding through hole 21. Then, each air intake pipe is connected to the main pipe, and the hot air is sent to the heat dissipation hole 11 through the main pipe. The heat dissipation hole 11 is then connected to the heat dissipation system. The air intake pipe and the main pipe can be metal pipes. The flow channel can guide the air, making the air flow more smoothly and avoiding turbulence or stagnation of hot air in the heat dissipation chamber 1, which would affect the heat dissipation efficiency.

[0076] In some embodiments, a blower fan is provided in the main duct, which drives the air in the guide channel to flow from the air inlet end of the air inlet duct to the air outlet end of the main duct.

[0077] Specifically, the air supply fan can be an axial flow fan. Installing an axial flow fan in the main duct can increase the airflow velocity in the main duct, which can further increase the airflow velocity in the entire guide channel, accelerate the discharge of hot air, and improve cooling efficiency.

[0078] In some embodiments, the door body 100 further includes: a top plate 6, which is located at the top of the heat dissipation cavity 1, and is connected to the outer door panel 3 and the inner door panel 2 respectively along the thickness direction of the door body 100; heat dissipation holes 11 are provided on the top plate 6.

[0079] Specifically, the door 100 can be a complete rectangular door frame composed of six door panels, which together form a heat dissipation cavity 1. Alternatively, it can be an incomplete rectangular door frame, including at least a top panel 6, a front door panel, and a rear door panel. When the door 100 closes the chassis, it can cooperate with the inner wall of the chassis to form the heat dissipation cavity 1 together with the inner wall of the door 100 and the rectangular door frame, which can save on manufacturing costs to a certain extent.

[0080] Please see Figure 4 , Figure 4This is a schematic cross-sectional view of the chassis structure disclosed in an embodiment of this application. This application discloses a chassis, including: a chassis body 200, a heat dissipation system, and the aforementioned chassis safety door; wherein, the heat dissipation system is used to exhaust air inside the chassis body 200 to the outdoors; wherein, the chassis safety door is closable and installable on the chassis body 200.

[0081] Specifically, the chassis can also be a machine, cabinet, etc., which can be placed inside the chassis when the quartz boat and silicon wafer are placed for cooling.

[0082] The chassis body 200 can be a rectangular box, and storage space can be set inside the chassis body 200 for placing items such as quartz boats and silicon wafers.

[0083] The top of the chassis body 200 can be equipped with an exhaust fan to remove heat to a certain extent. However, when the space inside the chassis body 200 is large and the temperature is high, the heat dissipation efficiency will be affected because the density of hot air increases, which weakens the upward force of hot air, causing most of the hot air to remain inside the chassis body 200.

[0084] A heat dissipation system can be installed in the chassis. The heat dissipation system can be equipped with a fan and pipes. The pipes can connect the heat dissipation chamber 1 to the external space. The fan installed in the pipes can provide power for the air, so that the air in the heat dissipation chamber 1 can flow to the outside.

[0085] The chassis safety door can be hinged to the chassis body 200, allowing the chassis safety door to open and close relative to the chassis. The chassis safety door has an open state and a closed state relative to the chassis. When it is open, items can be put into or taken out of the chassis. When it is closed, it can protect the items inside the chassis.

[0086] The chassis body 200 can be made of high-strength materials, such as stainless steel and aluminum alloy. Stainless steel is mainly composed of iron and carbon and has good crystallinity. Its strength mainly comes from its high carbon content. Steel can not only withstand high pressure, but also has high rigidity and corrosion resistance. Aluminum alloy has the characteristics of high strength and lightweight stability. By alloying with other metallic elements, the strength of aluminum alloy can be greatly improved. Common aluminum alloys include aluminum-copper alloys, aluminum-zinc alloys, and aluminum-magnesium alloys. The use of high-strength materials enables the chassis body 200 to withstand various mechanical stresses and environmental influences during the production process, ensuring long-term stable operation.

[0087] The chassis body 200 can also have a certain degree of sealing performance to ensure that the quartz boat and silicon wafer are not contaminated by the outside environment inside the chassis 200.

[0088] Outdoors generally refers to the space outside the working environment of the chassis. That is, when the chassis is set up in a workshop, outdoors can be the external environment of the workshop where the chassis is located.

[0089] The chassis safety door proposed in this application can directly exhaust the air inside the chassis to the outside through the heat dissipation system, which can quickly remove the heat inside the chassis and prevent a large amount of heat from dissipating into the workshop where the chassis is located. This not only prevents a large amount of heat from being transferred to the production workshop and affecting the working environment, but also meets the need for rapid heat dissipation, shortens the heat dissipation cycle, improves production efficiency, and prevents mutual interference between chassis.

[0090] In some embodiments, the top wall of the chassis body 200 has a heat dissipation system communication hole 20; the chassis safety door has a switchable open state and a closed state relative to the chassis body 200; when the chassis safety door is in the closed state, the air inlet end of the heat dissipation system communication hole 20 is connected to the heat dissipation hole 11, and the air outlet end of the heat dissipation system communication hole 20 is connected to the heat dissipation system, so that the heat dissipation chamber 1 is connected to the heat dissipation system.

[0091] Specifically, a heat dissipation system connection hole 20 corresponding to the heat dissipation hole 11 can be opened on the top wall of the chassis. When the chassis mounting door is in the closed state, the heat dissipation hole 11 is connected to the heat dissipation system connection hole 20, and the heat dissipation system connection hole 20 is used for the connection of the heat dissipation system. This can avoid the connection structure between the heat dissipation system and the heat dissipation cavity 1 affecting the rotation of the chassis safety door, so that the chassis safety door can switch normally between the open and closed states. When heat dissipation and cooling are required, the heat dissipation cavity 1 can be connected normally to the heat dissipation system to exhaust hot air to the outside.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
