Detailed Description

In order to make the technical problem, technical solution and beneficial effects to be solved by the present invention more clearly understood, the following description is made in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In this embodiment, the cabinet main body 10 is set as a server cabinet, and the size is not particularly limited, and may be set to be 600mm × 1200mm × 2000 mm. It should be understood that the type of the cabinet body 10 is not limited to a server cabinet, and other cabinets with similar functional requirements may be used, and is not limited thereto.

Referring to fig. 1 to fig. 7, a heat dissipation cabinet assembly with a skylight according to the present invention will be described. The heat dissipation cabinet assembly with the skylight comprises a cabinet main body 10, a beam 20, the skylight 30 and a locking piece 40; the top of the cabinet body 10 forms an opening; the number of the cross beams 20 is two, and the two cross beams 20 are arranged at the opening at intervals along the preset horizontal direction; two skylights 30 are arranged, the two skylights 30 are both positioned between the two cross beams 20, the two skylights 30 are both rotatably connected to the two cross beams 20, and the rotating shafts 310 of the two skylights 30 are both arranged near the middle parts of the cross beams 20, so that the back opening arrangement of the two skylights 30 is realized; the locking members 40 are connected to the cross member 20 and the louvers 30, respectively, to lock the positions of the two louvers 30 when the two louvers 30 are in the closed state.

Compared with the prior art, the heat dissipation cabinet assembly with the skylight provided by the embodiment has the advantages that the skylight 30 with the rotating shaft eccentrically arranged is arranged at the top of the cabinet main body 10, the relative sealing performance of the cabinet main body 10 can be kept in a closed state of the skylight 30, and after the locking piece 40 is unlocked, the two skylights 30 can be turned to a state of 90 degrees with the horizontal plane under the action of self gravity, so that the opening at the top of the cabinet main body 10 is fully opened, and the opening area is greatly increased.

If the top opening of the cabinet main body 10 is communicated with the cold channel of the data center, after the skylight 30 is opened, cold air in the cold channel can sink down from the opening at the top of the cabinet main body 10 and fill the cabinet main body 10, so that more effective refrigeration is realized; in case of fire, after the skylight 30 is opened, the opening area of the opening is larger, so that fire-fighting substances (such as fire-fighting gas or water) can enter the cabinet more quickly and greatly, and the fire-fighting efficiency is improved. Moreover, due to the back opening arrangement mode, the influence on the structure inside the cabinet main body 10 is small after the skylight 30 is turned over, and the design difficulty of the cabinet main body 10 is small.

In addition, the back opening of the embodiment requires less space above the cabinet main body 10 after the skylight 30 is opened, and is not easy to interfere with other structures above the cabinet main body, and if the cabinet is applied to a data center, the size and the design difficulty of a data center frame can be reduced.

Referring to fig. 6 and 7, an arrangement of the locking member 40 is an electromagnetic lock having a main lock body 410 disposed on the cross member 20 and an absorbing body 420 disposed on one of the louvers 30, defining the louver 30 on which the absorbing body 420 is disposed as a first louver 30a and the other louver 30 as a second louver 30b; the abutting side of the first louver 30a is further provided with a stopper 50, the stopper 50 is located at an upper edge of the abutting side, and when the first louver 30a and the second louver 30b are in the closed state, the stopper 50 limits the turning of the second louver 30b above the abutting side of the second louver 30 b.

The locking mode of the single-side electromagnetic lock is adopted, so that the using number of parts is reduced, and the using cost is reduced; on the basis, the stop member 50 in this embodiment can limit the upwarping action of the second louver 30b at the side closer to the rotation shaft 310, and then the louver 30 without the electromagnetic lock at the other side is ensured to be kept in the closed state by the stop member 50, and the effectiveness of locking is ensured under the condition that the single-side electromagnetic lock is arranged. In addition, due to the adoption of the electromagnetic lock, the unlocking process does not need manual operation of operators, and when overhigh temperature in the cabinet is detected or fire is sensed, the electromagnetic lock automatically unlocks according to an unlocking command, so that the skylight 30 is opened; in other use scenarios, under the state of catching fire, for circuit safety, the cabinet wholly cuts off the power supply, and the electromagnetic lock also cuts off the power supply and unblock thereupon, and skylight 30 is opened, can carry out the fire control operation afterwards, avoids appearing the circumstances that the skylight can not be opened after the outage. In a specific embodiment, there is one main lock 410 and one suction body 420.

In addition to the above embodiments, in order to avoid occupying the space above the cabinet body 10 and fully utilize the internal space of the cabinet body, the main lock body 410 is located below the cross beam 20, and the suction body 420 is correspondingly disposed on the downward side of the skylight 30, as shown in fig. 6 and 7.

In some embodiments, referring to fig. 5-7, the abutting side of the first louver 30a is provided with a first sealing strip 60a, and the abutting side of the second louver 30b is provided with a second sealing strip 60b; when the first louver 30a and the second louver 30b are in the closed state, the first weather strip 60a and the second weather strip 60b are in abutting contact in the axial direction of the cross member 20. This embodiment sets up the sealing strip respectively through the butt joint side in two skylight 30, and under the closure condition, the leakproofness of two skylight 30 butt joint positions can effectively be guaranteed in the butt joint of first sealing strip 60a and second sealing strip 60b, and simultaneously, elasticity extrusion effort also can help two skylight 30 to a certain extent to keep in the closure condition.

It should be noted that the abutting contact surfaces of the first sealing strip 60a and the second sealing strip 60b may be a plane (as shown in fig. 5), or may also be a wavy surface, a serrated surface, etc. (not shown in the drawings), which can meet the requirement of sealing performance, and is not limited herein.

In some embodiments, as shown in fig. 1 and 2, in order to enlarge the opening as much as possible, the opening area of the top of the cabinet body 10 is substantially consistent with the cross-sectional projection size of the cabinet body 10.

In addition, in the closed state, a side edge of the louver 30 far from the rotating shaft 310 and a corresponding edge of the opening, and the louver 30 and the cross beam 20 are required to be kept in sealing contact, so as to better keep the sealing state inside the cabinet main body 10, and in consideration of the large-amplitude turning action of the louver 30, members such as a relatively soft sealing sponge and the like can be arranged on the corresponding edge of the opening and the cross beam 20, and specific arrangement modes are not listed.

If the turning degree of the two louvers 30 is not limited, the downward-turned side edges of the two louvers 30 may collide with each other under the inertia effect, so that the structure of the louver 30 is damaged, and this problem is effectively avoided by providing the limiting members 70 for the two louvers 30. In particular implementations, the maximum flip angle of the skylight 30 is limited to 80-90.

In order to satisfy the rotating assembly of the skylight 30 and the cross beam 20 and simplify the assembly method, a rotating groove with an upward opening is formed in the cross beam 20, the rotating shaft 310 is rotatably arranged in the rotating groove, and a limiting body is arranged at the opening of the rotating groove to limit the displacement of the rotating shaft 310 in the opening direction of the rotating groove.
