A load device

Abstract

The present invention provides a load device, including a chassis and a resistor tube unit. The chassis is hollow to form a vertical heat dissipation duct from bottom to top. An opening is provided on one side of the chassis, and the resistor tube unit extends horizontally into the chassis through the opening. A supporting part is provided in the chassis to support the extending end of the resistor tube unit. The end of the resistor tube unit that remains outside is fixed at the opening of the chassis. The extending end of the resistor tube unit has an upper transverse part and a lower transverse part. Along the direction in which the resistor tube unit extends into the chassis, the upper transverse part moves to the upper part of the supporting part so as to be supported by the supporting part, and the lower transverse part moves to the lower part of the supporting part, so that the installation speed is fast and the installation process is simple. When a fan disposed below the heat dissipation duct with the air outlet facing upward blows air upward to dissipate heat, the lower transverse part abuts against the supporting part so that the resistor tube unit will not be blown upward and shake. In addition, the user only needs to loosen the end of the resistor tube unit that remains outside from the chassis to directly pull the resistor tube unit out of the load device, so that it is convenient to repair the resistor tube unit.

Description

Technical Field

[0001] The present invention relates to the field of loads, and in particular to a load device. Background Art

[0002] The load equipment is mainly composed of a chassis, a resistor unit, a control system and a protection system. The resistor unit is composed of multiple resistor tubes connected in series or in parallel. In high-power load equipment, there are a large number of resistor tubes. Therefore, in order to improve production efficiency, the resistor tubes need to be quickly fixed and installed when manufacturing high-power load equipment. Since a fan with an upward air outlet is usually set at the bottom of the load equipment to dissipate the heat of the resistor tube, both ends of the resistor tube need to be fixed to prevent the resistor tube from shaking. In addition, the large number of resistor tubes leads to dense installation, which makes the later maintenance of the resistor tube inconvenient.

[0003] There is a load device, in which a horizontal hook is provided in the chassis, the hook opening is facing upward, and the resistor tube is set to be U-shaped. The U-shaped resistor tube is equivalent to two straight resistor tubes connected in series. The bend of the U-shaped resistor tube is hooked on the hook, and the two ports are fixed on the chassis. In theory, installing the U-shaped resistor tube in this way can save a lot of installation time compared to installing a straight resistor tube. However, when installing the U-shaped resistor tube, the bend of the U-shaped resistor tube must be lifted up first so that it can be hooked on the hook, that is, the U-shaped resistor tube is more complicated to operate during installation, and such an installation process is both troublesome and time-consuming. In addition, when the U-shaped resistor tube in this load device is later repaired, the hook makes it difficult to disassemble the U-shaped resistor tube, resulting in inconvenient maintenance. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a load device which can be quickly and easily installed and conveniently maintained.

[0005] In order to solve the above technical problems, the present invention provides a load device, including a chassis and a resistor tube unit. The chassis is hollow to form a vertical heat dissipation duct from bottom to top. An opening is provided on one side of the chassis, and the resistor tube unit extends horizontally into the chassis through the opening. A supporting portion is provided in the chassis to support the insertion end of the resistor tube unit. The outer end of the resistor tube unit is fixed at the opening of the chassis, and the insertion end of the resistor tube unit has an upper transverse portion and a lower transverse portion; along the direction in which the resistor tube unit extends into the chassis, the upper transverse portion moves to the top of the supporting portion so as to be supported by the supporting portion, and the lower transverse portion moves to the bottom of the supporting portion.

[0006] Preferably, the resistor tube unit includes a horizontally placed U-shaped resistor tube and a supporting member arranged on the U-shaped resistor tube, the U-shaped resistor tube has the end at the bend as the insertion end, and the end at the ends of the two side strips as the external end, the supporting member belongs to the insertion end, and the upper transverse portion and the lower transverse portion are formed on the supporting member and are located below the U-shaped resistor tube.

[0007] Preferably, the two side bars of the U-shaped resistor tube pass through the supporting member, and the supporting member is fixed on the two side bars of the U-shaped resistor tube.

[0008] Preferably, the upper transverse portion and the lower transverse portion are formed to protrude on the supporting member along the direction in which the resistor tube unit extends into the chassis.

[0009] Preferably, in one resistor tube unit, there are two pairs of upper transverse portions and lower transverse portions, which are respectively located below the two side bars of the U-shaped resistor tube.

[0010] Preferably, the resistor tube unit includes a sealing member arranged on the U-shaped resistor tube, which belongs to an external end, and the external end is fixed at the opening of the chassis through the sealing member.

[0011] Preferably, the two side strips of the U-shaped resistor tube pass through the sealing piece, and the sealing piece is fixed on the two side strips of the U-shaped resistor tube. The resistor tube unit extends laterally into the chassis through the opening and extends until its insertion end is supported by the supporting part, and the sealing piece moves to the opening of the chassis so that it can be fixed at the opening.

[0012] Preferably, as the resistor tube unit extends transversely into the chassis through the opening, the supported member can pass through the opening of the chassis in terms of shape and size, but the sealing member cannot pass through.

[0013] Preferably, a plurality of resistor tube units are arranged in the same layer, and their insertion ends are supported by the same supporting portion.

[0014] Preferably, the supporting portion is a transverse rod.

[0015] Preferably, the rod is an insulating rod.

[0016] Preferably, the resistor tube unit has multiple layers, and the supporting portion also has multiple layers accordingly.

[0017] Preferably, the side surface of the chassis having the opening is an insulating plate.

[0018] The present invention has the following beneficial effects: when the user installs the resistor tube unit on the load device, he only needs to first extend the resistor tube unit from the opening into the chassis horizontally, so that the upper horizontal part of the insertion end moves to the top of the supporting part so as to be supported by the supporting part, and the lower horizontal part moves to the bottom of the supporting part, and then the end of the resistor tube unit remaining outside is fixed on the chassis, so that the installation speed is fast and the installation process is simple. After the resistor tube unit is installed, when the fan disposed below the heat dissipation duct with the air outlet facing upward blows air upward to dissipate the heat of the resistor tube unit, the lower horizontal part abuts against the bottom of the supporting part so that the resistor tube unit will not be blown upward and shaken. In addition, the user only needs to loosen the end of the resistor tube unit remaining outside from the chassis to directly pull the resistor tube unit out of the load device, thereby facilitating the maintenance of the resistor tube unit.

DETAILED DESCRIPTION

[0026] like Figure 1 As shown, the resistor tube unit includes a U-shaped resistor tube 1, a sealing member 2 and a support member 3. The sealing member 2 is arranged on the U-shaped resistor tube 1 near the ends of the two side strips. The sealing member 2 is provided with two screw holes 21. The support member 3 is arranged near the bend of the U-shaped resistor tube 1. Figure 1 In the embodiment, the U-shaped resistor tube 1 has the ends of the two side strips as the outer ends, the end of the U-shaped resistor tube 1 at the bending position as the insertion end, the sealing member 2 belongs to the outer end, the entrusted member 3 belongs to the insertion end, and the left and right ends of the entrusted member 3 protrude toward the insertion end to form an upper transverse portion 4 and a lower transverse portion 5, as shown in FIG. Figure 2 As shown, the two pairs of upper transverse portions 4 and lower transverse portions 5 are respectively located below the two side strips of the U-shaped resistor tube 1 .

[0027] When manufacturing the resistor tube unit, first, let the ends of the two side strips of the U-shaped resistor tube 1 pass through the supporting member 3, then move the supporting member 3 to the U-shaped resistor tube 1 near the bending position, and then weld and fix the supporting member 3 to the U-shaped resistor tube 1; after welding the supporting member 3, let the ends of the two side strips of the U-shaped resistor tube 1 pass through the sealing member 2, and then weld and fix the sealing member 2 to the U-shaped resistor tube 1 near the ends of the two side strips.

[0028] like Figure 3As shown, the load device includes a chassis, and the chassis includes a panel 6, a back panel 7 and two side panels 8. The panel 6, the back panel 7 and the two side panels 8 form a vertical heat dissipation duct from bottom to top, and a fan with an upward air outlet is provided below the vertical heat dissipation duct (not shown in the figure). There are twenty-five layers of resistor tube units in the chassis, and each layer has four resistor tube units. The panel 6 is an insulating plate to prevent short circuits between all resistor tube units. Twenty-five insulating rods 9 used as supporting parts are spanned between the two side panels 8. These insulating rods 9 are arranged from top to bottom, and four resistor tube units on the same layer are supported by the same insulating rod 9. All the resistor tube units are fixed on the load device. Specifically, the distance between the sealing member 2 and the supporting member 3 is equal to the distance between the panel 6 and the insulating rod 9. In this way, as the resistor tube unit extends horizontally into the chassis through the opening 10 and extends into the upper horizontal portion 5 of the supporting member 3 to be supported by the insulating rod 9, the sealing member 2 can just be supported on the panel 6, so that the sealing member 2 can be fixed on the panel 6, and Figure 4 It can be seen that the upper transverse portion 4 is supported by the insulating rod 9, and the lower transverse portion 5 is located below the insulating rod 9, and cooperates with the upper transverse portion 4 to clamp the insulating rod 9 (in other non-preferred embodiments, the upper transverse portion 4 and the lower transverse portion 5 may not clamp the insulating rod 9, but in this way, the insertion end of the resistor tube unit is easy to shake up and down), so that when the fan blows upward to dissipate the heat of the resistor tube unit, the resistor tube unit will not be blown upward and shake. In this embodiment, the insulating rod 9 is preferably a mica string rod.

[0029] In other embodiments, the two pairs of upper transverse portions 4 and lower transverse portions 5 may be respectively located above the two side strips of the U-shaped resistor tube 1, so that after the upper transverse portions 4 and the lower transverse portions 5 cooperate with each other to clamp the insulating rod 9, the U-shaped resistor tube 1 is located below the insulating rod; the two lower transverse portions 5 may also be located below the two side strips of the U-shaped resistor tube 1, the two upper transverse portions 4 are not located above the two side strips of the U-shaped resistor tube 1, or the supporting member 3 does not protrude to form the upper transverse portion 4, so that the insulating rod 9 supports the U-shaped resistor tube 1, and the lower transverse portion 5 is located below the insulating rod 9, and cooperates with the U-shaped resistor tube 1 to clamp the insulating rod 9; the two upper transverse portions 4 may also be located above the two side strips of the U-shaped resistor tube 1, the two lower transverse portions 5 are not located below the two side strips of the U-shaped resistor tube 1, or the supporting member 3 does not protrude to form the lower transverse portion 5, so that the insulating rod 9 supports the two upper transverse portions 4, the U-shaped resistor tube 1 is located below the insulating rod 9, and cooperates with the upper transverse portion 4 to clamp the insulating rod 9. No matter how the relative positions of the U-shaped resistor tube 1, the upper transverse portion 4 and the lower transverse portion 5 are arranged, it is sufficient as long as it can ensure that the insertion end of the resistor tube unit can clamp the insulating rod 9.

[0030] Figure 5 This is a schematic diagram of the installation process of one of the resistor tube units. Figure 5 A partial enlarged view of Figure 6) It can be seen that the panel 6 is provided with an opening 10 for inserting the resistor tube unit, and the size of the opening 10 is larger than the entrusted part 3 and smaller than the sealing part 2. As the resistor tube unit extends laterally into the chassis through the opening 10, the entrusted part 3 can pass through the opening 10 on the panel 6, but the sealing part 2 cannot pass through, and the sealing part 2 seals the opening 10. There is a screw hole 11 at each of the left and right ends of the opening 10. The user inserts the bend of the U-shaped resistor tube 1 and the support member 3 into the load device from the opening 10 on the panel 6 until the upper transverse portion 4 and the lower transverse portion 5 on the support member 3 clamp the insulating rod 9. At this time, the sealing member 2 is just against the panel 6, and the screw hole 21 on the sealing member 2 is aligned with the screw hole 11 on the panel 6. The user then screws the screw 12 (the same as the screw 12 used to install other sealing members 2) into the screw hole 21 on the sealing member 2. The screw 12 passes through the screw hole 21 on the sealing member 2 and then screws into the screw hole 11 on the panel 6, thereby fixing the sealing member 2 on the panel 6, so that the resistor tube unit is fixed on the load device as a whole. In the above installation process, the user only needs to let the resistor tube unit extend straight into the chassis from the opening 10, without adjusting the insertion angle, so that the installation speed is fast and the installation process is simple. In addition, the user only needs to loosen the sealing member 2 of the resistor tube unit from the chassis to directly pull the resistor tube unit out of the chassis of the load device, thereby facilitating the user to repair the resistor tube unit.
