[0001] The invention relates to the technical field of electrical installation, in particular to an electrical equipment installation assembly. Background Art

[0002] In the power distribution cabinet, the most common and convenient way to fix electrical equipment such as circuit breakers, transformers, and control hosts is to use track grooves.

DETAILED DESCRIPTION

[0033] See also Figure 1-Figure 8: In the present embodiment: it includes a modular liquid-air integrated heat dissipation substrate 1, and the surface of the modular liquid-air integrated heat dissipation substrate 1 is provided with a plurality of positioning heat-conducting holes 2 distributed in a matrix, and the positioning heat-conducting holes 2 are used to fix the electrical equipment installation module and ventilate and dissipate heat, and the fixed electrical equipment installation module is composed of a bell-mouth air-gathering connection sleeve 4 and a snap-fit ​​heat-conducting and air-permeable connection end 5, and the snap-fit ​​heat-conducting and air-permeable connection end 5 is installed at the equipment installation surface 100 of the modular liquid-air integrated heat dissipation substrate 1, and is used to provide a buckling area for the electrical equipment, and the bell-mouth air-gathering connection sleeve 4 is installed at the threading auxiliary installation surface 200 of the modular liquid-air integrated heat dissipation substrate 1, and is used to fix the snap-fit ​​heat-conducting and air-permeable connection end 5, and at the same time, the incoming air at the threading auxiliary installation surface 200 is gathered and transported to the snap-fit ​​heat-conducting and air-permeable connection end 5, and the snap-fit ​​heat-conducting and air-permeable connection end 5 is used to dissipate heat from the electrical equipment.

[0034] In this embodiment: the modular liquid-air integrated heat dissipation substrate 1 can be made of a metal material with good heat dissipation performance. A plurality of positioning heat conduction holes 2 are provided on the modular liquid-air integrated heat dissipation substrate 1. The liquid flow channel 3 is arranged in an S-shaped disk inside the modular liquid-air integrated heat dissipation substrate 1. The coolant flows through the liquid flow channel 3, so that the inner wall of the positioning heat conduction hole 2 and the surface of the modular liquid-air integrated heat dissipation substrate 1 have an excellent low-temperature environment for sufficient heat dissipation. At present, in order to make the lines neat and tidy, the power distribution cabinet separates the electrical installation surface from the threading surface, such as the equipment installation surface 100 and the threading auxiliary installation surface 200. The electrical equipment is installed on the equipment installation surface 100, and the wires are passed through the positioning heat conduction holes 2 to the threading auxiliary installation surface 200. The wire bundling operation is performed through the threading auxiliary installation surface 200. The power distribution cabinet adopts a double-door form, and only the back needs to be checked when checking the line. At this time, the cable is fixed at the auxiliary threading installation surface 200, so the threading auxiliary installation surface 200 can be installed with a wire card and a matching cooling fan. The airflow generated by the cooling fan can be gathered through the bell-shaped air gathering connection sleeve 4, and then pass through the snap-fitting heat-conducting and ventilation connection end 5 to act on the back of the electrical equipment, and be diverted through the snap-fitting heat-conducting and ventilation connection end 5. Combined with the heat exchange effect of the positioning heat-conducting hole 2 and the heat-conducting sleeve 51 and the heat dissipation effect of the modular liquid-air integrated heat dissipation substrate 1, the low-temperature wind can act well on the electrical equipment, thereby effectively cooling the electrical equipment.

[0035] In this embodiment: the engaging heat-conducting and ventilated connecting end 5 includes a heat-conducting sleeve 51 in contact with the inner wall of the positioning heat-conducting hole 2, and the modular liquid-air integrated heat dissipation substrate 1 is provided with a liquid flow channel 3, and the liquid flow channel 3 performs heat exchange on the positioning heat-conducting hole 2 and the heat-conducting sleeve 51. The end surface of the heat-conducting sleeve 51 is fixedly connected with an inner polygonal plate 52 and an outer polygonal plate 53, and a straight card groove 54 is formed between the inner polygonal plate 52 and the outer polygonal plate 53 to provide a card connection track for the electrical equipment.

[0036] In this embodiment: the heat-conducting sleeve 51 is cylindrical, and the heat-conducting sleeve 51 fits with the inner wall of the positioning heat-conducting hole 2. When the liquid flow channel 3 acts on the modular liquid-air integrated heat dissipation substrate 1 to cool down, the positioning heat-conducting hole 2 is in a low-temperature state, and the temperature of the positioning heat-conducting hole 2 is replaced with the heat-conducting sleeve 51, so that the heat-conducting sleeve 51 is in a cooling state. The polygonal inner polygonal plate 52 and the outer polygonal plate 53 have multiple sets of tracks at the same time, because the principle of the track groove is to provide two parallel buckle surfaces, wherein the inner polygonal plate 52 fits with the modular liquid-air integrated heat dissipation substrate 1 to prevent the heat-conducting sleeve 51 from being displaced, and the outer polygonal plate 53 forms a buckle surface, and the linear buckle groove 54 receives the buckle of the electrical equipment, so that the two parallel edges can form a buckle surface, so that the connection of different buckle types can be achieved by switching the buckle parallel surface during use, thereby increasing applicability.

[0037] In this embodiment: a hole body connected to the inner cavity of the heat-conducting sleeve 51 is opened at the outer polygonal plate 53, and the inner hole of the outer polygonal plate 53 smoothly transitions to the surface of the outer polygonal plate 53 through the exhaust dispersion arc surface 55, and a plurality of exhaust grooves 56 connected to the heat-conducting sleeve 51 are opened on the surface of the outer polygonal plate 53.

[0038] In this embodiment: when the equipment is fixed, the outer polygonal plate 53 will fit the equipment and cause poor ventilation. Therefore, an exhaust dispersion arc surface 55 and an exhaust slot 56 are provided. After passing through the heat conductive sleeve 51, the wind acts vertically on the back of the equipment and flows around. At this time, it can be discharged to the outside of the equipment through the exhaust slot 56, so that the cold air flows parallel to the back of the electrical equipment to achieve heat exchange.

[0039] In this embodiment: an internal thread 511 is provided at one end of the heat-conducting sleeve 51 away from the outer polygonal plate 53, and the bell-mouth wind-gathering connecting sleeve 4 is threadedly fixed to the internal thread 511. The end of the bell-mouth wind-gathering connecting sleeve 4 has a wind-gathering arc surface 42 that is tangent to the inner hole of the bell-mouth wind-gathering connecting sleeve 4. The wind-gathering arc surface 42, the heat-conducting sleeve 51, and the exhaust and dispersion arc surface 55 form a channel for gathering, ventilating, and dispersing wind.

[0040] In this embodiment: when fixing, hold the bell-mouth wind-gathering connecting sleeve 4, and rotate and fix it with the internal thread 511. At this time, when the wind at the threading auxiliary installation surface 200 acts on the wind-gathering arc surface 42, the wind is concentrated into the heat-conducting sleeve 51 through the wind-gathering arc surface 42, and is discharged through the exhaust dispersion arc surface 55 and the exhaust groove 56.

[0041] In the present embodiment: the outer wall of the bell-mouth wind gathering connecting sleeve 4 is fixedly connected to a limiting flat ring 41, a plurality of countersunk screw holes 11 are provided at the threading auxiliary installation surface 200, and the countersunk screw holes 11 are distributed in groups of two on both sides of the positioning heat conduction hole 2, and the bottom surface of the limiting flat ring 41 is fixedly connected to an elastic block 411 matching the countersunk shape of the countersunk screw holes 11.

[0042] In the present embodiment: the material of the elastic block 411 is rubber. In order to prevent the engaged heat-conducting and ventilating connecting end 5 from rotating, a limiting flat ring 41 is provided. The limiting flat ring 41 rotates synchronously with the bell-mouth wind-collecting connecting sleeve 4. When the elastic block 411 approaches the surface of the modular liquid-air integrated heat dissipation substrate 1, relative displacement will occur. At this time, the elastic block 411 undergoes elastic deformation. The limiting flat ring 41 continues to rotate so that the elastic block 411 enters the countersunk part of the countersunk screw hole 11 and the bell-mouth wind-collecting connecting sleeve 4 and the engaged heat-conducting and ventilating connecting end 5 will not shake in the axial direction of the positioning heat-conducting hole 2.

[0043] In this embodiment: the inner polygonal plate 52 and the outer polygonal plate 53 have the same shape, and the inner polygonal plate 52 and the outer polygonal plate 53 have the same shape and are both even polygons, with a minimum of four sides and forming at least four grooves, two of the four grooves distributed in parallel form a group, the width of each group of grooves is different, and the spacing between each group of parallel sides is different.

[0044] In this embodiment: the quadrilateral has two groups of parallel grooves, and the hexagon has three groups of parallel grooves. The form of multiple even-numbered sides can be set according to needs. The width of the groove and the spacing between each group of parallel sides can be adjusted to adapt to different types of buckles. When in use, you only need to rotate it.

[0045] The components installed on the threading auxiliary installation surface 200 include a cable tie, a cable card, a cooling fan, and a sensor. Since there is a cable tie on the back, the cable tie can prevent the line from affecting the ventilation of the positioning thermal conductive hole 2, the cooling fan is to enhance the heat dissipation effect of the high-temperature equipment, and the sensor is to monitor the temperature of the cable tie.

[0046] Steps:

[0047] S1: Fix the modular liquid-air integrated heat dissipation substrate 1 in the power distribution cabinet, and respectively connect the cooling water inlet pipe and the cooling water discharge pipe through the two ports of the liquid flow channel 3, and connect the cooler to realize liquid cooling of the modular liquid-air integrated heat dissipation substrate 1;

[0049] S3: After the engaging heat-conducting and ventilating connecting end 5 is arranged according to the distribution conditions through S2, the bell-mouth air-collecting connecting sleeve 4 is passed through the positioning heat-conducting hole 2 from the threading auxiliary installation surface 200 and fixed with the engaging heat-conducting and ventilating connecting end 5, the elastic clamping block 411 is engaged with the countersunk screw hole 11 so that the bell-mouth air-collecting connecting sleeve 4 cannot rotate, and the heat-conducting sleeve 51 contacts the inner wall of the positioning heat-conducting hole 2 and cooperates with the liquid flow channel 3 to realize heat exchange;

[0050] S4: After the electrical equipment is fixed, the connecting cable is passed through the positioning heat conduction hole 2 to the auxiliary threading installation surface 200, and the line is fixed by the arc surface 43 of the clamping wire and the limit flat ring 41, and the wire clamp is fixed by the countersunk screw hole 11 to separate the wire and the equipment surface, and the heat is dissipated through the liquid flow channel 3;

[0051] S5: Install the cooling fan through the countersunk screw hole 11. The wind blown by the cooling fan is gathered by the wind gathering arc surface 42, passes through the heat conductive sleeve 51 and directly reaches the back of the device. The wind is blown out through the exhaust dispersion arc surface 55 and the exhaust slot 56. With the heat exchange effect of the heat conductive sleeve 51 and the liquid flow channel 3, the cooling wind moves horizontally along the back of the device.
