Description

Technical Field

[0001] The invention relates to an electrical cabinet, and in particular to cooling of components inside the electrical cabinet. Background Art

[0002] The electrical cabinet is equipped with an inverter, which is used to convert direct current into alternating current. The inverter works for a long time, generates heat, and needs to be cooled. The common cooling measure is to exchange heat between cooling water and the inverter. The cooling water flows through the inverter through the water pipe and exchanges heat with the inverter. The cooling water in the water pipe needs to exchange heat with the space outside the electrical cabinet. The cooling water circulates inside and outside the electrical cabinet through the water pipe. Summary of the invention

[0003] The technical problem solved by the present invention is to design a cooling water adapter so that cooling water can cool down multiple inverters in an electrical cabinet through a water pipe.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a cooling water adapter for an electrical cabinet, comprising an adapter body and an adapter installed on the adapter body, the adapter body being provided with a main water inlet and a main water outlet, a plurality of branch water inlets connected to the main water inlet, and a plurality of branch water outlets connected to the main water outlet, the branch water inlets and the branch water outlets being connected with adapters, the adapter of the branch water inlet being connected to one end of a branch water pipe, and the other end of the branch water pipe being connected to the adapter of the branch water outlet, the branch water pipe being located in the electrical cabinet and passing through an inverter, and the adapter body being installed on the outer wall of the electrical cabinet.

[0005] The number of branch water inlets is equal to the number of branch water outlets. Each inverter in the electrical cabinet is equipped with a cooling water pipe, one end of which is connected to a branch water inlet, and the other end is connected to a branch water outlet. Several inverters are equipped with several cooling water pipes, and all cooling water pipes are arranged in parallel on the adapter body. The cooling water of the main water inlet enters all branch water inlets at the same time, and the main water outlet receives the cooling water of all branch water outlets at the same time. The main water inlet and the main water outlet are connected to the water pipe outside the electrical cabinet. The water pipe can be connected to the radiator to cool the cooling water and then circulate it into the electrical cabinet. Among them, the cooling water pipe is connected to the branch water inlet through an adapter, and the cooling water pipe is connected to the branch water outlet through an adapter.

[0006] The adapter body is in the shape of a rectangular parallelepiped, with the main water inlet and the main water outlet arranged on the bottom surface of the adapter body, the first group water inlet and the first group water outlet arranged on the right side of the adapter body, the second group water inlet and the second group water outlet arranged on the left side of the adapter body, and the right side of the adapter body is provided with a connection hole connected to the outer wall of the electrical cabinet. The right side of the adapter body is close to the outer wall of the electrical cabinet, and the outer wall of the electrical cabinet is provided with an adapter clearance hole for the adapter on the adapter body to pass through. The first group water inlet and the first group water outlet on the right side of the adapter body are connected to the cooling water pipe in the electrical cabinet. The second group water inlet and the second group water outlet can be used according to actual needs. For example, if the inverter in another adjacent electrical cabinet needs to be cooled, the cooling water pipe can be connected to the second group water inlet and the second group water outlet through an adapter to cool the inverter in the other electrical cabinet.

[0007] The first component water inlet and the first component water outlet, as well as the idle sub-water inlet and sub-water outlet in the second component water inlet and the second component water outlet, need to be sealed with plugs.

[0008] As an option, the adapter is installed on the branch water inlet and the branch water outlet by screw connection. The branch water inlet and the branch water outlet are provided with internal threads, and the adapter is provided with an external thread section matching the internal threads.

[0009] The adapter includes an adapter body and a clamping assembly, the clamping assembly includes a first elastic ring and a second elastic ring arranged inside and outside, and a plurality of wedges clamped between the first elastic ring and the second elastic ring, the plurality of wedges are distributed along the circumference of the first elastic ring, the first elastic ring has a first notch, and the second elastic ring has a second notch; the inner wall of the adapter body is provided with an annular groove, the first elastic ring is clamped in the annular groove, and the wedges are against the inner wall of the adapter body. One end of the cooling water pipe goes deep into the adapter body and acts on the inclined surface of the wedge, so that a circle of wedges expands outward, the first elastic ring is expanded and accumulates elastic potential energy, and the second elastic ring is no longer pressed by a circle of wedges and releases elastic potential energy. One end of the water pipe is inserted into a circle of wedges and the second elastic ring. Since the enlarged first elastic ring has a tendency to shrink, this tendency causes a circle of wedges to shrink, and further, the second elastic ring has a tendency to shrink. The shrinking tendency causes a circle of wedges and the second elastic ring to clamp the water pipe, thereby achieving a quick and stable connection between the water pipe and the adapter.

[0010] The outer side wall of the wedge-shaped piece is provided with a first clamping groove, and the inner side wall of the wedge-shaped piece is provided with a second clamping groove. The first clamping groove is clamped with the first elastic ring piece, and the second clamping groove is clamped with the second elastic ring piece.

[0011] The adapter body is equipped with a plastic guide, and a notch is provided at one end of the plastic guide close to the clamping assembly, and a limiting edge is provided at one end of the plastic guide away from the clamping assembly, and the limiting edge is located outside the adapter body. When the water pipe end is plugged into the adapter, the water pipe end is first inserted into the plastic guide and then into the clamping assembly. When the water pipe needs to be pulled out of the adapter, the plastic guide is pressed into the adapter body, and the inner end of the plastic guide contacts the inclined surface of a circle of wedge-shaped pieces to open the clamping assembly, so that the water pipe can be pulled out of the adapter. When the clamping assembly is opened, the end of the plastic guide that contacts the clamping assembly shrinks, the notch becomes smaller, and the plastic guide undergoes elastic deformation. After the water pipe is pulled out of the adapter, the operator releases the plastic guide, the plastic guide returns to its original state, detaches from the clamping assembly and resets, and the notch returns to its original size.

[0012] A metal reinforcement kit is inserted into the end of the water pipe inserted into the adapter, and one end of the metal reinforcement kit is flanged, and the flange is against the end face of the water distribution pipe. The metal reinforcement kit is first inserted into the end of the water distribution pipe, and then the end of the water distribution pipe is inserted into the adapter. In this way, the end of the water distribution pipe is strengthened, and the clamping assembly can be effectively opened, so that the water distribution pipe is inserted into the clamping assembly and clamped by the clamping assembly.

[0013] The present invention cooperates with a cooling water pipe (i.e. a water distribution pipe) to enable the cooling water to cool down a plurality of inverters in the electrical cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The adapter is installed on the branch water inlet and the branch water outlet by screw connection.

[0030] Combination Figures 4 to 7 The adapter 20 includes an adapter body 21 and a clamping assembly 22, the clamping assembly includes a first elastic ring 221 and a second elastic ring 222 arranged inside and outside, and a plurality of wedges 223 clamped between the first elastic ring and the second elastic ring, the plurality of wedges are distributed circumferentially along the first elastic ring, the first elastic ring has a first notch 224, and the second elastic ring has a second notch 225; an annular groove 211 is provided on the inner side wall of the adapter body, the first elastic ring is clamped in the annular groove, and the wedges are abutted against the inner side wall of the adapter body.

[0031] A first slot is formed on the outer side wall of the wedge-shaped member 223 , and a second slot is formed on the inner side wall of the wedge-shaped member. The first slot is engaged with the first elastic ring member 221 , and the second slot is engaged with the second elastic ring member 222 .

[0032] A plastic guide 23 is provided in the adapter body 21. A notch 231 is provided at one end of the plastic guide close to the clamping assembly 22. A limiting edge 232 is provided at one end of the plastic guide away from the clamping assembly. The limiting edge is located outside the adapter body.

[0033] like Figure 2 A metal reinforcement kit 40 is inserted into the end of the water distribution pipe 30 inserted into the adapter 20, and one end of the metal reinforcement kit is flanged, and the flange is against the end face of the water distribution pipe.

[0034] The right side of the adapter body 10 is in close contact with the outer wall of the electrical cabinet, and the outer wall of the electrical cabinet is provided with an adapter clearance hole for the adapter 20 on the adapter body to pass through. The first component water inlet 13 and the first component water outlet 14 on the right side of the adapter body are connected to the cooling water pipe in the electrical cabinet. The number of the first component water inlet 13 is equal to the number of the first component water outlet 14. Each inverter in the electrical cabinet is equipped with a cooling water pipe, which is the branch water pipe 30. One end of the cooling water pipe is connected to a branch water inlet in the first component water inlet 13, and the other end is connected to a branch water outlet in the first component water outlet 14. Several inverters are equipped with several cooling water pipes, and all cooling water pipes are arranged in parallel on the adapter body 10. The cooling water of the main water inlet 11 enters all the branch water inlets at the same time, and the main water outlet 12 receives the cooling water of all the branch water outlets at the same time. The main water inlet and the main water outlet 12 are connected to the water pipe outside the electrical cabinet, and the water pipe can be connected to the radiator to cool the cooling water and then circulate it into the electrical cabinet.

[0035] The cooling water pipe is connected to the branch water inlet through an adapter 20, and the cooling water pipe is connected to the branch water outlet through an adapter. The branch water inlet and the branch water outlet are provided with internal threads, and the adapter 20 is provided with an external thread section 24 that matches the internal threads.

[0036] The connection method of the cooling water pipe (i.e., the water distribution pipe 30) and the adapter 20 is as follows. The metal reinforcement kit 40 is first inserted into the end of the water distribution pipe 30, and then the end of the water distribution pipe is inserted into the adapter 20. One end of the water distribution pipe penetrates into the adapter body 21 and acts on the inclined surface of the wedge 223, so that a circle of wedges expands outward, the first elastic ring 221 is expanded and accumulates elastic potential energy, and the second elastic ring 222 is no longer compressed by a circle of wedges 223 and releases elastic potential energy. One end of the water distribution pipe is inserted into a circle of wedges and the second elastic ring 222. Since the enlarged first elastic ring 221 has a tendency to shrink, this tendency makes a circle of wedges have a tendency to shrink, and then, the second elastic ring 222 has a tendency to shrink, and the shrinking tendency makes a circle of wedges and the second elastic ring clamp the water distribution pipe 30, so as to achieve a quick and stable connection between the water distribution pipe and the adapter.

[0037] The separation method of the cooling water pipe (i.e., the water distribution pipe 30) and the adapter 20 is as follows. When the end of the water distribution pipe 30 is plugged into the adapter 20, the end of the water distribution pipe is first inserted into the plastic guide 23 and then inserted into the clamping assembly 22. When the water distribution pipe 30 needs to be pulled out from the adapter, the operator presses the plastic guide 23 into the adapter body 21, and the inner end of the plastic guide contacts the inclined surface of a circle of wedge-shaped pieces 223 to open the clamping assembly 22, so that the water distribution pipe can be pulled out from the adapter 20. When the clamping assembly is opened, the end of the plastic guide 23 that contacts the clamping assembly 22 is closed, the notch 231 becomes smaller, and the plastic guide is elastically deformed. After the water distribution pipe 30 is pulled out of the adapter 20, the operator releases the plastic guide 23, the plastic guide returns to its original state, detaches from the clamping assembly 22 and resets, and the notch 231 returns to its original size.

[0038] The second component water inlet 15 and the second component water outlet 16 can be used according to actual needs. For example, if an inverter in another adjacent electrical cabinet needs to be cooled, a cooling water pipe can be connected to the second component water inlet and the second component water outlet through an adapter 20 to cool the inverter in the other electrical cabinet.

[0039] The first component water inlet 13 and the first component water outlet 14, as well as the idle sub-water inlet and sub-water outlet in the second component water inlet 15 and the second component water outlet 16 need to be sealed with plugs.

[0040] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
