Description

Technical Field

[0001] This application relates to the field of ventilation and heat dissipation technology, and in particular to a temperature-controlled openable ventilation window. Background Technology

[0002] In enclosed spaces such as computer rooms, warehouses, power distribution cabinets, and energy storage containers, heat is generated during equipment startup or storage, causing the internal temperature to rise. To maintain air circulation and lower the temperature within these enclosed spaces, ventilation windows are typically installed. These windows can be opened and closed in various ways, either manually or with the aid of electronic control equipment.

[0003] Currently, most ventilation windows rely on electric actuators, cylinders, and other electronic control devices for remote opening and closing. However, when the temperature inside the enclosed space exceeds normal levels, if the electric actuators, cylinders, or other electronic control devices used to remotely open the window sash experience a power outage, short circuit, or if the operator fails to activate the control devices in time, the ventilation window will not open properly. This prevents effective air exchange between the enclosed space and the outside, hindering the reduction of flammable gas concentrations and preventing proper heat dissipation, thereby increasing the risk of explosion or thermal runaway within the enclosed space. Utility Model Content

[0004] In order to ensure the normal opening of the ventilation window in the event of failure of the electronic control device for opening the ventilation window, and to reduce the possibility of explosion or thermal runaway in the sealed space, this application provides a temperature-controlled opening ventilation window.

[0005] The temperature-controlled openable ventilation window provided in this application adopts the following technical solution:

[0006] A temperature-controlled openable ventilation window includes a frame for installation on a closed space housing, the frame having an opening through which the closed space communicates with the outside, and a baffle that is movably opened and closed on the frame, the baffle being used to control the opening and closing of the opening;

[0007] The frame is provided with an elastic component for pushing the baffle to open. When the baffle is closed, it is fixed to the frame by a temperature-controlled locking component. When the temperature reaches a preset value, the temperature-controlled locking component releases the connection between the baffle and the frame.

[0008] By adopting the above technical solution, when the temperature inside the enclosed space is low, the temperature-controlled locking assembly fixes the baffle to the frame to maintain the airtightness of the enclosed space shell; when the temperature reaches the preset value, the temperature-controlled locking assembly releases the connection between the baffle and the frame, and the elastic component pushes the baffle to open, so as to reduce the concentration of combustible gas inside the enclosed space and also mitigate the possibility of thermal runaway.

[0009] Optionally, the baffle is hinged to the frame via a pivot, and the elastic component includes a torsion spring sleeved on the pivot, with one end of the torsion spring abutting against the baffle and the other end of the torsion spring abutting against the frame, so as to push the baffle toward opening.

[0010] By adopting the above technical solution, the torsion spring has a simple structure and is easy to install. It can provide a stable opening driving force for the baffle, so that the baffle can be opened smoothly after the temperature-controlled locking component is disconnected.

[0011] Optionally, a slide block is slidably disposed on the frame, and a connecting rod is connected between the slide block and the baffle. The movement of the slide block drives the baffle to flip through the connecting rod. An elastic component is disposed between the frame and the slide block, and the elastic component is used to drive the slide block to move so as to drive the baffle to open.

[0012] By adopting the above technical solution, the cooperation of the elastic component, the slide and the connecting rod realizes the flipping movement of the baffle. The elastic component is set between the frame and the slide, and when the baffle is released from the locked state, the elastic component drives the slide to move so that the baffle tends to open.

[0013] Optionally, the temperature-controlled locking assembly includes a first fusible link disposed on the frame, and the baffle is provided with a slot for the first fusible link to be inserted. When the temperature reaches the set value of the first fusible link, the first fusible link releases the locking effect on the slot.

[0014] By adopting the above technical solution, the first fuse rod has a simple structure and can automatically melt when the temperature reaches the set value, thereby releasing the locking effect on the baffle and allowing the baffle to open under the action of the elastic component.

[0015] Optionally, the temperature-controlled locking assembly includes a second fusible link connected between the slide and the frame, the second fusible link being used to limit the slide from sliding under the elastic force of the elastic component.

[0016] By adopting the above technical solution, the second fuse rod can restrict the movement of the slide. When the temperature reaches the set value, the second fuse rod melts and the slide moves under the action of the elastic component, which drives the baffle to open through the connecting rod.

[0017] Optionally, the temperature-controlled locking assembly includes a mounting base installed on the frame, a limit rod slidably disposed on the mounting base, a limit hole for the limit rod to be inserted into the baffle, and a temperature-sensing glass bulb and a rebound unit disposed between the mounting base and the limit rod.

[0018] The rebound unit is used to push the limiting rod towards disengaging from the limiting hole, and the temperature-sensitive glass bulb is used to push the limiting rod so that the limiting rod remains inserted in the limiting hole. When the temperature reaches the set value of the temperature-sensitive glass bulb, the temperature-sensitive glass bulb breaks to release the pushing effect on the limiting rod.

[0019] By adopting the above technical solution, the temperature-sensing glass bulb and the rebound unit work together. When the temperature is low, the temperature-sensing glass bulb pushes the limiting rod into the limiting hole to fix the baffle. When the temperature reaches the set value, the temperature-sensing glass bulb breaks, and the rebound unit pushes the limiting rod out of the limiting hole, so that the baffle can be opened.

[0020] Optionally, the frame has a raised rib around the opening, and the baffle has a sealing gasket for abutting against the raised rib.

[0021] By adopting the above technical solution, the combination of the convex ridge and the sealing gasket can improve the sealing performance when the baffle is closed and reduce the stability of external dust, rainwater and other substances entering the enclosed space.

[0022] Optionally, the outer edge of the baffle is provided with a folded edge, and when the baffle is closed, the folded edge is located outside the protruding ridge.

[0023] By adopting the above technical solution, the folded edge can further enhance the sealing effect of the baffle.

[0024] Optionally, a retaining ring is provided on the frame, and the baffle is located inside the retaining ring when the baffle is closed. The side wall of the retaining ring is provided with a through hole for connecting the inside and outside of the retaining ring.

[0025] By adopting the above technical solution, the retaining ring can play a certain protective role for the baffle, and the through hole is used to drain the water accumulated between the convex edge and the retaining ring.

[0026] In summary, this application includes at least one of the following beneficial technical effects: when the temperature inside the enclosed space is low, the temperature-controlled locking assembly fixes the baffle to the frame, maintaining the airtightness of the enclosed space shell; when the temperature reaches a preset value, the temperature-controlled locking assembly releases the connection between the baffle and the frame, and the elastic component pushes the baffle open, thereby opening the opening to reduce the concentration of combustible gas inside the enclosed space and also to mitigate the possibility of thermal runaway.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. Example 1

[0036] This application discloses a temperature-controlled, openable ventilation window. For example... Figure 1 , Figure 2 as well as Figure 3 The temperature-controlled openable ventilation window includes a frame 1, which is used to install on the shell of an enclosed space, such as the wall or shell of a machine room, warehouse, or energy storage container. The frame 1 is provided with an opening 11, through which the enclosed space communicates with the outside space.

[0037] A baffle 12 is movably opened and closed on the frame 1. The baffle 12 is hinged to the frame 1 via a pivot 13, allowing the baffle 12 to rotate around the pivot 13, thereby controlling the opening and closing of the opening 11. When the baffle 12 is closed, the opening 11 is sealed, preventing air circulation between the enclosed space and the outside; when the baffle 12 is open, the opening 11 is opened, allowing air exchange between the inside and outside of the enclosed space and enabling timely heat dissipation.

[0038] To improve the sealing performance of the baffle 12 when closed, a raised rib 14 is provided around the opening 11 on the frame 1, and a sealing gasket 15 is provided on the baffle 12. When the baffle 12 is flipped towards the frame 1 to the closed state, the raised rib 14 presses the sealing gasket 15 against the baffle 12, improving the sealing effect between the baffle 12 and the frame 1. A folded edge 16 is provided around the outer edge of the baffle 12. When the baffle 12 is closed, the folded edge 16 is located outside the raised rib 14, reducing the possibility of rainwater entering and further enhancing the sealing effect.

[0039] A retaining ring 17 is provided on the frame 1. When the baffle 12 is closed, it is located inside the retaining ring 17, which reduces the possibility of excessive external airflow blowing the baffle 12 open. It also reduces the problem of external hard objects hitting the edge of the baffle 12, thus protecting the baffle 12. A through hole 18 is provided on the side wall of the retaining ring 17 for draining accumulated water.

[0040] An elastic component 2 is provided on the frame 1, which is used to push the baffle 12 towards the open state. Specifically, the elastic component 2 is connected between the frame 1 and the baffle 12. The elastic component 2 can be a spring, a pneumatic spring, or an elastic band, etc. In this embodiment, the elastic component 2 is a torsion spring 21 sleeved on the rotating shaft 13. One end of the torsion spring 21 abuts against the baffle 12, and the other end abuts against the frame 1. The torsion spring 21 applies a force to the baffle 12, causing the baffle 12 to tend to flip away from the frame 1, so that the opening 11 tends to open under the action of the torsion spring 21.

[0041] When the baffle 12 is closed, it is fixed to the frame 1 by the temperature-controlled locking assembly 3. In this embodiment, the temperature-controlled locking assembly 3 includes a first fusible link 31 disposed on the frame 1, and the baffle 12 has a slot 33 for inserting the first fusible link 31. The first fusible link 31 is detachably mounted on the frame 1. Specifically, the protruding rib 14 has a mounting hole 32, and the first fusible link 31 is inserted into the mounting hole 32 and slot 33 through the opening 11 to achieve a locking effect on the baffle 12. One end of the first fusible link 31 located inside the opening 11 is fixedly connected to an end plate 34, and a locking bolt 35 is threaded onto the end plate 34 to fix the position of the first fusible link 31 on the frame 1.

[0042] At low temperatures, the first fuse rod 31 remains intact, inserted into the slot 33, firmly fixing the baffle 12 to the frame 1, thus closing the opening 11. When the temperature inside the enclosed space rises to the set value of the first fuse rod 31, the first fuse rod 31 melts, releasing the locking effect on the slot 33. At this time, under the elastic force of the torsion spring 21, the baffle 12 rotates around the pivot 13 and opens, allowing air circulation between the enclosed space and the outside, thereby reducing the concentration of combustible gases inside the enclosed space and also achieving a cooling effect. Example 2

[0043] like Figure 4 and Figure 5 In this embodiment, all other aspects are the same as in Embodiment 1, except that a slide block 4 is slidably mounted on the frame 1, and the slide block 4 can reciprocate on the frame 1 in a direction perpendicular to the axis of rotation 13. A connecting rod 41 connects the slide block 4 and the baffle 12, with both ends of the connecting rod 41 hinged to the slide block 4 and the baffle 12, respectively. When the slide block 4 slides on the frame 1, the connecting rod 41 drives the baffle 12 to rotate around its hinge point with the frame 1, thereby controlling the opening and closing of the opening 11.

[0044] The elastic component 2 is disposed between the frame 1 and the slide 4, indirectly driving the cover plate towards the open state. The elastic component 2 can be a spring, a pneumatic spring, or an elastic band, etc. In this embodiment, the elastic component 2 is a tension spring 22, with one end connected to the frame 1 and the other end connected to the slide 4. The tension spring 22 is always in a stretched state, and its elastic force applies a force to the slide 4, causing the slide to have a tendency to move, which in turn pushes the baffle 12 towards opening through the connecting rod 41.

[0045] The temperature-controlled locking assembly 3 of this embodiment includes a second fusible link 42 connected between the slide block 4 and the frame 1. The second fusible link 42 is used to limit the slide block 4 from sliding under the force of the spring. When the temperature is low, the second fusible link 42 remains intact, preventing the slide block 4 from sliding under the force of the tension spring 22, thus keeping the baffle 12 in a closed state. When the temperature in the enclosed space rises to the set value of the second fusible link 42, the second fusible link 42 melts, and the slide block 4 slides under the force of the spring. This causes the baffle 12 to rotate around the pivot 13 between itself and the frame 1 via the connecting rod 41, opening the opening 11. Example 3

[0046] like Figure 6 and Figure 7In this embodiment, all other aspects are the same as in Embodiment 1, except that the temperature-controlled locking assembly 3 includes a mounting base 5 disposed on the frame 1. A limiting rod 52 is slidably disposed on the mounting base 5, and a limiting hole 51 for the limiting rod 52 to be inserted into is provided on the baffle 12. A temperature-sensitive glass bulb 53 and a spring-loaded unit 54 are disposed between the mounting base 5 and the limiting rod 52. The spring-loaded unit 54 is a spring, with one end connected to the mounting base 5 and the other end connected to the limiting rod 52. Under the elastic force of the spring, the limiting rod 52 tends to retract into the mounting base 5. The temperature-sensitive glass bulb 53 is supported between the mounting base 5 and the limiting rod 52, allowing the limiting rod 52 to extend out of the mounting base 5. The temperature-sensitive glass bulb 53 is filled with a special temperature-sensitive liquid. When the temperature reaches a preset value, the temperature-sensitive glass bulb 53 will rupture due to the expansion of the temperature-sensitive liquid, thus releasing the supporting effect on the limiting rod 52.

[0047] When the temperature is low, the temperature-sensing bulb 53 is supported between the mounting base 5 and the limiting rod 52, pushing the limiting rod 52 out of the mounting base 5 and inserting it into the limiting hole 51, fixing the baffle 12 to the frame 1, and keeping the opening 11 closed. At the same time, the spring is in a compressed state, and its elastic force applies a force to the limiting rod 52, causing the limiting rod 52 to tend to retract into the mounting base 5.

[0048] When the temperature inside the enclosed space rises to the set value of the temperature-sensing bulb 53, the temperature-sensing liquid inside the bulb expands to a certain extent, causing the bulb to burst and releasing its pushing effect on the limiting rod 52. At this time, the spring, under its own elastic force, pushes the limiting rod 52 to slide towards the mounting base 5 and disengage from the limiting hole 51, releasing the fixation on the baffle 12. The baffle 12 opens under the action of the elastic component 2, causing the opening 11 to open.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
