Referring to fig. 1-3, in a preferred embodiment of the present utility model, the UPS module with high power density includes an outer box 100, a main power device 500, a radiator 700 and an air duct 150 disposed in the outer box 100, wherein the main power device 500 and the radiator 700 are disposed in the air duct 150, a mounting groove 710 extending from an upper surface to a lower surface of the radiator 700 is formed in the radiator 700, the mounting groove 710 is disposed in an upper half of the air duct 150, and the main power device 500 is mounted in the mounting groove 710. The above components are each described in further detail below.

In a preferred embodiment, the high power density UPS module mainly includes an outer box 100 and an input conductor 300, an output conductor 400, a main power device 500, an auxiliary control board 510, a control unit 600, a heat sink 700, an air deflector 800, and a fan assembly 900 mounted in the outer box 100.

The outer case 100 has a box shape as a whole, and includes a main case 110, a front cover 120, an upper cover 130, and a connection terminal fixing frame 140. The main box 110 is generally in a "U" shape, and includes a bottom plate (not numbered in the figure) opposite to the bottom plate and two side plates (not numbered in the figure) parallel to each other. The front cover 120 is disposed opposite to the connection terminal holder 140 with the air duct 150 (see fig. 2 and 3) disposed therebetween. The front cover 120 is provided with an air inlet 121 for supplying air into the air duct 150, and the connecting terminal fixing frame 140 is provided with an air outlet 141 for exhausting air in the air duct 150.

The input opposite terminal block 210 and the output opposite terminal block 220 are fixedly mounted on the connection terminal fixing frame 140. Specifically, as shown in fig. 1, a plurality of input-to-plug terminal holders 210 are provided at the upper half of the connection terminal holder 140; as shown in fig. 2, a plurality of output opposite-plug terminal holders 220 are provided at the lower half of the connection terminal holder 140. Wherein the input butt plug terminal block 210 is used for being connected with the input conductor 300, and the output butt plug terminal block 220 is used for being connected with the output conductor 400. The high power density UPS module performs current input and output through the input counter terminal block 210 and the output counter terminal block 220.

As shown in fig. 2, the main power device 500 and the heat sink 700 are disposed at the middle of the air duct 150. The heat sink 700 is generally square and has a plurality of heat dissipation fins (not numbered). The heat sink 700 is provided with a mounting groove 710 extending from the upper surface to the lower surface thereof. The mounting groove 710 is formed in the upper half of the air duct 150, and the main power device 500 is embedded in the mounting groove 710, i.e., the main power device 500 is inverted in the mounting groove 710. Specifically, the mounting groove 710 may be formed by opening a whole heat sink 700, or may be formed by splicing a plurality of heat sinks 700. The wind is caught in a lot of fine dust while flowing in the wind tunnel 150, and the dust falls down to the lower portion of the heat sink 700 by gravity. Since the main power device 500 is disposed at the upper half of the air duct 150, although the main power device 500 is exposed to the air duct 150, dust is not accumulated for a long period of use, and the safety of the entire module is improved.

In this application, the UPS module with high power density further includes an input conductor 300, where the input conductor 300 covers the mounting slot 710 and the main power device 500. As shown in fig. 3, the input conductors 300 are specifically provided with 3 input conductors including an a input conductor, a B input conductor, and a C input conductor. The A input conductor, the B input conductor, and the C input conductor are arranged parallel to each other in the horizontal direction. It will be appreciated that the number of input conductors 300 may vary as desired. One end of the input conductor 300 is fixedly connected with the input opposite terminal base 210, and the other end is directly overlapped on the main power device 500.

The current input to the socket terminal block 210 is transmitted to the corresponding main power device 500 through the input conductor 300, the current is processed through the main power device 500, and the processed current is output through the output conductor 400 and the output socket terminal block 220. Corresponding to the input conductors 300, the output conductors 400 are specifically provided with 3 pieces, including an a output conductor, a B output conductor, and a C output conductor. The A output conductor, the B output conductor and the C output conductor are arranged in parallel with each other in the horizontal direction and are respectively arranged in parallel with the A input conductor, the B input conductor and the C input conductor in the vertical direction. One end of the output conductor 400 is directly lapped on the main power device 500, and the other end is fixedly connected with the output opposite-plug terminal base 220.

By arranging the input conductor 300 and the output conductor 400 in this way, the wiring time is obviously reduced, the cable cost is reduced, and the assembly efficiency of the module is improved.

As shown in fig. 2 and 3, the high power density UPS module further includes a fan assembly 900 for enhancing air circulation within the air chute 150, the fan assembly 900 being mounted within the air chute 150. Specifically, the fan assembly 900 is mounted at the air intake 121 of the air duct 150. The fan assembly 900 includes a plurality of blades corresponding to the main power device 500.

Preferably, as shown in fig. 2, the high power density UPS module further includes an air deflector 800. The air deflector 800 is disposed above the air duct 150, and extends from the air inlet 121 of the air duct 150 toward the main power device 500. The top end of the auxiliary control board 510 is fixedly connected with the lower surface of the air deflector 800. Since the auxiliary control board 510 is suspended on the lower surface of the air deflector 800, dust falls downward under the action of gravity and is not deposited on the auxiliary control board 510.

As shown in fig. 2 and 3, the high power density UPS module further includes a control unit 600. The control unit 600 is disposed between the air guide plate 800 and the outer case 100, specifically, above the air guide plate 800. Namely, the control unit 600 is installed above the wind deflector 800, and the auxiliary control board 510 is installed below the wind deflector. Since the control unit 600 is not provided in the duct 150, there is no problem of dust deposition.

The UPS module with high power density of the utility model mainly maximizes the power density, simplifies the structure and greatly improves the heat dissipation effect and protects key devices by reasonable structural layout and good air duct design.

The foregoing is merely exemplary of the present utility model, and many variations may be made in the specific embodiments and application scope of the utility model by those skilled in the art based on the spirit of the utility model, as long as the variations do not depart from the gist of the utility model.
