[0048] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] Combine the following Figures 1 to 9 , the cabinet provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0050] In some embodiments, Figure 1 As shown, this embodiment provides a cabinet, including a cabinet body 11.

[0051] The cabinet 11 is provided with a receiving chamber 111 , an air inlet chamber 112 and an air exhaust chamber 113 ; the receiving chamber 111 is used for receiving electronic equipment.

[0052] A first air inlet 1111 and a first air outlet 1112 are provided on the inner wall of the accommodating chamber 111; the accommodating chamber 111 is connected with the air inlet chamber 112 via the first air inlet 1111, and a second air inlet 1121 connected with the outside is provided on the inner wall of the air inlet chamber 112; the accommodating chamber 111 is connected with the air exhaust chamber 113 via the first air outlet 1112, and a second air outlet 1131 connected with the outside is provided on the inner wall of the air exhaust chamber 113; the first air inlet 1111 is located above the second air inlet 1121, and the first air outlet 1112 is located above the second air outlet 1131.

[0053] The first air inlet 1111 is used to supply air into the accommodating cavity 111 , and the first air outlet 1112 is used to exhaust the air in the accommodating cavity 111 .

[0054] It is understandable that the cabinet 11 of this embodiment can be a cabinet of a rectangular parallelepiped, a cylinder or other shapes, and can be specifically designed according to actual needs, and this application does not limit it. The cabinet 11 is structured to form a receiving cavity 111 to accommodate various electronic devices, electronic components, etc. Various equipment brackets can also be installed in the receiving cavity 111 according to actual needs to install and fix the electronic equipment in the receiving cavity 111.

[0055] The air inlet cavity 112 of this embodiment is connected to the first air inlet 1111 of the accommodating cavity 111, and the air inlet cavity 112 is provided with a second air inlet 1121 connected to the outside, and the outside air can enter the accommodating cavity 111 through the second air inlet 1121 and the first air inlet 1111 in sequence (such as Figure 1 At the same time, since the first air inlet 1111 is located above the second air inlet 1121, even if some water enters the air inlet cavity 112 through the second air inlet 1121, it is difficult to enter the first air inlet 1111, but will slide down along the inner wall of the air inlet cavity 112 and flow out from the second air inlet 1121, thereby preventing water from flowing into the air inlet cavity 111.

[0056] Similarly, the exhaust cavity 113 of the present embodiment is connected to the first exhaust port 1112 of the accommodating cavity 111, and the exhaust cavity 113 is provided with a second exhaust port 1131 connected to the outside, and the hot air after heat exchange in the accommodating cavity 111 can be discharged through the first exhaust port 1112 and the second exhaust port 1131 in sequence (such as Figure 1At the same time, since the first air outlet 1112 is also located above the second air outlet 1131, after the moisture enters the air outlet cavity 113 through the second air outlet 1131, it will slide down along the inner wall of the air outlet cavity 113 and be discharged from the second air outlet 1131.

[0057] It is understandable that for the convenience of installation and maintenance, the air inlet chamber 112 and the air exhaust chamber 113 are usually arranged on the same side of the accommodating chamber 111; but the air inlet chamber 112 and the air exhaust chamber 113 can also be arranged on different sides of the accommodating chamber 111 according to actual needs.

[0058] The cabinet of the utility model realizes a ventilation and heat dissipation cycle in the accommodating cavity 111 by arranging a first air inlet 1111 and a first air outlet 1112 on the accommodating cavity 111. The first air inlet 1111 and the first air outlet 1112 are connected to the outside through the air inlet cavity 112 and the air outlet 113 respectively, and ventilate and exhaust the accommodating cavity 111 respectively; at the same time, by arranging the first air inlet 1111 and the second air inlet 1121 in a staggered manner, and arranging the first air outlet 1112 and the second air outlet 1131 in a staggered manner, moisture entering the air inlet cavity 112 and the air outlet 113 cannot enter the accommodating cavity 111 through the first air inlet 1111 and the first air outlet 1112, so as to achieve a waterproof effect.

[0059] It can be seen from the above that the cabinet of the utility model can not only directly dissipate heat and ventilation with the external air, with good heat dissipation effect, but also has a waterproof effect through the reasonable arrangement of the air inlet and exhaust outlet, without the need for an additional waterproof layer, with a simple structure and small space occupation.

[0060] It is understandable that the second air inlet 1121 and the second air outlet 1131 are usually covered with dustproof nets or shutters, which can intercept some moisture and dust and play a certain waterproof and dustproof role for the air inlet cavity 112 and the air outlet cavity 113.

[0061] In some embodiments, Figure 1 and Figure 2 As shown, the cabinet of this embodiment further includes an air intake device 12 and an air exhaust device 13 .

[0062] The air inlet device 12 is disposed at the first air inlet 1111 to introduce air into the accommodating cavity 111 .

[0063] The exhaust device 13 is disposed at the first exhaust port 1112 to exhaust air to the exhaust cavity 113 .

[0064] It is understandable that the air inlet device 12 and the air exhaust device 13 of this embodiment both include power elements such as fans or blowers to deliver air. The air inlet device 12 is disposed at the first air inlet 1111 to pass the air in the air inlet cavity 112 into the accommodating cavity 111 to ventilate and dissipate heat for the electronic equipment in the accommodating cavity 111.

[0065] The exhaust device 13 of this embodiment is arranged at the first exhaust port 1112 to pass the air in the accommodating chamber 111 into the exhaust chamber 113 and exhaust it from the exhaust chamber 113, so that the air in the accommodating chamber 111 and the external air can be continuously circulated and ventilated, and the heat dissipation effect is better.

[0066] In some embodiments, Figures 3 to 5 As shown, the air intake device 12 of this embodiment includes a filter assembly 121 and an air intake fan 122 .

[0067] The filter assembly 121 is disposed at the first air inlet 1111 , and the air inlet fan 122 is disposed at one side of the filter assembly 121 .

[0068] It is understandable that the filter assembly 121 of this embodiment is arranged at the position of the first air inlet 1111. Generally speaking, the filter assembly 121 can cover the entire first air inlet 1111 so as to filter the air entering the accommodating chamber 111 from the first air inlet 1111 to remove dust and impurities mixed in the air. Optionally, the filter assembly 121 can also be provided with a dehumidification structure to further remove moisture from the air.

[0069] The air inlet fan 122 of this embodiment is disposed on one side of the filter assembly 121 so as to pass air into the accommodating chamber 111. Optionally, the air inlet fan 122 can be disposed on the side of the filter assembly 121 facing the accommodating chamber 111, so that the air will pass through the air inlet fan 122 only after being filtered by the filter assembly 121, thereby reducing dust accumulation on the air inlet fan 122; or, the air inlet fan 122 can also be disposed on the side of the filter assembly 121 facing the air inlet chamber 112, so that the user can conveniently inspect and replace the air inlet fan 122.

[0070] In some embodiments, Figure 5 As shown, the filter assembly 121 of this embodiment includes a filter support 1211 and a filter 1212 .

[0071] The filter bracket 1211 is connected to the cabinet 11 ; the filter 1212 is installed on the filter bracket 1211 and covers the first air inlet 1111 .

[0072] The filter bracket 1211 of this embodiment is connected to the cabinet 11. Specifically, the filter bracket 1211 is usually fixedly connected to the inner wall of the air inlet chamber 112 or the accommodating chamber 111, and can be connected by bolts or snaps, which is not limited in this application. The filter bracket 1211 is used to support and fix the filter 1212, and the filter 1212 is used to filter out impurities, moisture, etc. in the air. Generally speaking, the filter 1212 includes one or more dust-proof and dehumidification structures such as a filter net and an adsorbent such as activated carbon.

[0073] In some embodiments, Figure 5 and Figure 6 As shown, the filter assembly 121 further includes an elastic abutment 1213 .

[0074] The filter bracket 1211 is installed in the accommodating cavity 111 , and at least a portion of the filter bracket 1211 is disposed opposite to the inner wall of the accommodating cavity 111 to form a mounting groove, and the filter 1212 is disposed in the mounting groove.

[0075] One end of the elastic abutment member 1213 is connected to the inner wall of the installation groove, and the other end abuts against the filter 1212 to press the filter 1212 into the installation groove.

[0076] The filter bracket 1211 of this embodiment is installed in the accommodating cavity 111, and a part of the structure of the filter bracket 1211 is opposite to the inner wall of the accommodating cavity 111 with a certain gap, thereby forming an installation groove, and the filter 1212 is arranged in the installation groove to position the filter 1212.

[0077] The elastic abutment 1213 of this embodiment is arranged in the gap between the filter 1212 and the inner wall of the installation groove, abuts against the filter 1212, and presses the filter 1212 against the inner wall on the other side of the installation groove, thereby fixing the filter 1212 and preventing the filter 1212 from shaking and falling off in the installation groove; at the same time, when the filter 1212 needs to be inspected and replaced, it is only necessary to compress the elastic abutment 1213 to pull the filter 1212 out of the installation groove, and the structure is simple, convenient and labor-saving.

[0078] It is understandable that the elastic abutment 1213 can be connected to the inner wall of the accommodating chamber 111 to press the filter 1212 against the filter bracket 1211 , or can be connected to the filter bracket 1211 to press the filter 1212 against the inner wall of the accommodating chamber 111 .

[0079] It is understandable that there are usually multiple elastic abutting members 1213, which are arranged at intervals at the boundary positions of the installation groove (such as each corner), so that the force on the filter 1212 is more evenly dispersed when it is pressed, and the fixation is more stable.

[0080] In some embodiments, Figure 6 As shown, the elastic abutment member 1213 of this embodiment includes a ball, a housing and a spring.

[0081] The shell is configured with a mounting hole, and a side of the shell away from the opening of the mounting hole is connected to the inner wall of the mounting groove.

[0082] The spring is arranged in the mounting hole, one end of the spring is connected to the bottom of the mounting hole, and the other end abuts against the ball; the ball is rollably arranged in the mounting hole; the spring is in a compressed state to abut against the ball, so that a part of the ball extends out of the opening of the mounting hole to press the filter 1212.

[0083] The shell structure of this embodiment is provided with a mounting hole to accommodate and fix the spring and the ball. The spring can be extended and retracted in the mounting hole. When the spring is in a free state, a part of the ball extends out of the orifice of the mounting hole so as to abut against the filter 1212; when the filter 1212 is installed in the mounting groove, the spring is in a compressed state, so that the ball abuts against the filter 1212, pressing and fixing the filter 1212; when the filter 1212 is disassembled and assembled, when the filter 1212 is pulled out of the mounting groove or inserted into the mounting groove, the ball can roll in the mounting hole under the friction of the filter 1212 after contacting the filter 1212, thereby reducing the friction force on the filter 1212 during the plugging and unplugging process, making the filter 1212 easier to disassemble and assemble.

[0084] It is understandable that the aperture of the mounting hole is usually set to be smaller than the diameter of the ball so as to block the ball and prevent it from falling out of the aperture.

[0085] In some embodiments, Figure 1 As shown, the air inlet fan 122 of this embodiment is disposed on a side of the filter assembly 121 facing the accommodating cavity 111 .

[0086] The air inlet fan 122 is a forward and reverse blowing fan.

[0087] The inlet fan 122 of this embodiment is arranged in the accommodating chamber 111. The external air will pass through the inlet fan 122 only after passing through the filter component 121, which can effectively reduce the dust accumulation in the inlet fan 122 and extend the service life of the inlet fan 122; at the same time, the inlet fan 122 is a forward and reverse blowing fan, and the wind direction of the inlet fan 122 is adjustable. When the equipment in the cabinet is running and the temperature is high, the inlet fan 122 can draw cold air outside the cabinet into the accommodating chamber 111 to exchange heat for the electronic equipment in the accommodating chamber 111; when the equipment is shut down, the inlet fan 122 can blow in the opposite direction, and the dust attached to the surface of the filter component 121 can be blown out of the air inlet chamber 112, thereby realizing the dust cleaning function and extending the service life of the filter component 121.

[0088] In some embodiments, Figure 2 , Figure 7 and Figure 8As shown, the exhaust device 13 includes an exhaust fan 131 , and the air duct direction of the exhaust fan 131 is inclined toward the second exhaust port 1131 .

[0089] The exhaust fan 131 of this embodiment is used to exhaust the air in the accommodating chamber 111 into the exhaust chamber 113 and exhaust it from the second exhaust port 1131. At the same time, since the first exhaust port 1112 is above the second exhaust port 1131, the air duct direction of the exhaust fan 131 is inclined toward the second exhaust port 1131, that is, the exhaust direction of the exhaust fan 131 is inclined downward, and the air extraction direction is inclined upward. Since the hot air in the accommodating chamber 111 will float up and gather at the top of the accommodating chamber 111, the exhaust fan 131 draws air obliquely upward, which can better draw the hot air into the exhaust chamber 113 and exhaust it from the exhaust chamber 113, and the heat dissipation effect is better.

[0090] Generally speaking, since the first air outlet 1112 is mainly used to supply air to the outside without filtering, the exhaust fan 131 can also be set as a one-way fan, which has a simpler structure and is easy to install.

[0091] Optionally, in order to further maintain a clean environment in the accommodating chamber 111 , a filter assembly 121 similar to the aforementioned embodiment may also be provided at the first air outlet 1112 .

[0092] In some embodiments, Figure 1 , Figure 2 , Figure 5 , Figure 7 and Fig. 9 As shown, the cabinet of this embodiment further includes an air inlet cover 14 and an air exhaust cover 15 .

[0093] The air inlet cover 14 and the air exhaust cover 15 are both detachably connected to the inner wall of the cabinet 11 .

[0094] The air inlet cover 14 and the inner wall of the cabinet 11 together form an air inlet cavity 112; the air inlet cover 14 is constructed with a first guide surface 141, the first guide surface 141 is arranged opposite to the second air inlet 1121, the first guide surface 141 gradually inclines toward the second air inlet 1121 from the top to the bottom, and the bottom end of the first guide surface 141 is located at the second air inlet 1121.

[0095] The exhaust hood 15 and the inner wall of the cabinet 11 together form an exhaust cavity 113; the exhaust hood 15 is constructed with a second guide surface 151, which is arranged opposite to the second exhaust port 1131, and the second guide surface 151 gradually inclines toward the second exhaust port 1131 from the top to the bottom, and the bottom end of the first guide surface 141 is located at the second exhaust port 1131.

[0096] The air inlet hood 14 of the present embodiment is disposed on the inner wall of the cabinet 11, and together with the inner wall forms an air inlet cavity 112; the air exhaust hood 15 is disposed on the inner wall of the cabinet 11, and together with the inner wall forms an air exhaust cavity 113; when it is necessary to clean and maintain the air inlet cavity 112 and the air exhaust cavity 113, the air inlet hood 14 and the air exhaust hood 15 can be directly removed for cleaning and maintenance, which is easy to operate.

[0097] In this embodiment, the first guide surface 141 and the second air inlet 1121 are arranged opposite to each other. After the external air enters the air inlet cavity 112 through the second air inlet 1121, it will first contact the first guide surface 141. The first guide surface 141 is arranged obliquely, which can guide the airflow upward, so that the airflow can enter the accommodating cavity 111 through the first air inlet 1111; some moisture may enter the air inlet cavity 112 through the second air inlet 1121, and the moisture entering the air inlet cavity 112 will flow back to the second air inlet 1121 under the guidance of the first guide surface 141, and flow out from the second air inlet 1121, so as to avoid moisture accumulation in the air inlet cavity 112.

[0098] It is understandable that the function of the second guide surface 151 of the present embodiment is similar to that of the first guide surface 141. On the one hand, it can guide the gas discharged from the first exhaust port 1112 above to the second exhaust port 1131. On the other hand, it can redirect the moisture entering the exhaust cavity 113 to flow back to the second exhaust port 1131 and flow out from the second exhaust port 1131 to avoid the accumulation of moisture in the exhaust cavity 113.

[0099] It is understandable that the edge of the air inlet cover 14 or the air exhaust cover 15 is connected and fixed to the cabinet body 11 by bolt connection, snap connection, pin connection, etc., and this application does not limit this.

[0100] It is understandable that in order to prevent moisture or dust from entering the accommodating cavity 111 through the connecting gap between the air inlet hood 14 or the exhaust hood 15 and the cabinet 11, the connecting gap between the air inlet hood 14 or the exhaust hood 15 and the cabinet 11 is sealed with sealing materials or structures, such as sealing rings, sealants, etc., to further enhance the waterproof and dustproof nature of the accommodating cavity 111.

[0101] In a specific embodiment, a door panel that can be opened and closed is provided on one side of the cabinet 11, and a second air inlet 1121 and a second air outlet 1131 are provided on the inner side of the door panel; the air inlet cover 14 is provided on the second air inlet 1121, and is combined with the door panel to form an air inlet cavity 112; the air outlet cover 15 is provided on the second air outlet 1131, and is combined with the door panel to form an air outlet cavity 113. By opening the door panel, the equipment in the cabinet can be maintained, or the air inlet cavity 112 and the air outlet cavity 113 can be cleaned and maintained, and the operation is convenient.

[0102] In some embodiments, Figure 1As shown, the air inlet cavity 112 of this embodiment is located below the air outlet cavity 113 .

[0103] It can be understood that the air inlet chamber 112 of the present embodiment is used to pass external cold air into the accommodating chamber 111 to dissipate heat for the equipment in the accommodating chamber 111. After the cold air absorbs heat, the temperature increases and the density decreases, and it will gradually flow upward and gather; and the exhaust chamber 113 is located above the air inlet chamber 112, so that the hot air at a high place can be first extracted and discharged to the outside, which can better promote the air heat dissipation cycle inside and outside the cabinet and achieve better heat dissipation effect.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
