Description

Technical Field

[0001] The utility model relates to a converter, in particular to a charging converter for a locomotive. Background Art

[0002] With the progress of technology, new energy electric vehicles have gradually entered daily life, and the means of obtaining electricity have also gradually improved. In new energy electric vehicles, the charging gun directly connects the power source to the electrical system through a plug to charge the vehicle.

[0003] Based on the current situation, the extended use of electric energy is applied to locomotives. Compared with current cars, locomotives have a huge body structure, have higher voltage requirements for the power source, and have a very large current at the moment of charging access, resulting in a huge heat release effect. Obviously, the existing charging connectors cannot meet the actual use requirements. Using the current connectors will cause damage to the electrical system at the moment when the power source enters. Therefore, it is necessary to improve the existing charging connectors. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a connector that can meet the charging of locomotives under high voltage conditions to solve the instantaneous heat effect problem under large voltage charging in view of the heat release effect.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A charging converter for a locomotive includes a box body. Connecting heads are respectively arranged on different sides of the box body. Conductive columns are arranged in the box body. Both ends of the conductive columns are respectively connected to the connecting heads, and a heat dissipation structure is arranged on the conductive columns.

[0007] In the above technical solution, a heat dissipation structure is connected to each conductive column. A heat conduction pad is arranged between the heat dissipation structure and the box body, and the heat conduction pad is respectively connected to the heat dissipation structure and the box body.

[0008] In the above technical solution, the heat dissipation structure includes a plurality of heat dissipation fins.

[0009] In the above technical solution, a breathing joint is arranged on the side surface of the box body.

[0010] In the above technical solution, a breathing joint is arranged on the side surface of the box body where no connecting head is provided.

[0011] In the above technical solution, the inside of the box body is a cavity. The connecting heads are symmetrically arranged on two opposite side surfaces, and the heat dissipation structures are symmetrically connected to the conductive columns.

[0012] The core idea of this solution is to improve on the basis of the traditional charging connector, adding a heat dissipation structure between the traditional charging connector and the power consumption system terminal to dissipate heat during instantaneous charging.

[0013] This solution uses three methods for heat dissipation:

[0014] First, by means of several heat dissipation fins of the heat dissipation structure, the contact surface of the heat dissipation structure is increased, and the heat is diffused into the cavity of the box body, and the heat radiation principle is used to dissipate heat from the conductive column;

[0015] Second, the heat dissipation structure is plugged into the heat conduction pad. The heat conduction pad is an insulating rubber. On the premise of insulation, the heat conduction pad quickly transfers the heat on the heat dissipation structure body to the box body. The box body is made of metal, and the surface area of the box body is used to contact other installation surfaces, so as to conduct the heat out of the box body to achieve conduction heat dissipation;

[0016] Third, breathing joints are symmetrically arranged on the side surface of the box body. By using the working principle of the breathing joints, a convection is formed between the hot air in the cavity of the box body and the cold air outside the box body, and the heat radiation in the box body is cooled.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are:

[0018] The charging converter of this solution can be used on locomotives, and can realize the functions of DC fast charging of 250A and super charging of 600A, greatly improving the charging efficiency and can be widely used on locomotives. Brief Description of the Drawings

[0019] The present utility model will be described by way of examples and with reference to the accompanying drawings, wherein:

[0020] Figure 1 is a schematic diagram of the internal structure of the converter;

[0021] Among them: 1 is the box body, 2 is the charging interface, 3 is the heat dissipation structure, 4 is the conductive column, 5 is the heat conduction pad, 6 is the breathing joint, and 7 is the high-current interface. Detailed Embodiments

[0022] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0023] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless specifically stated, can be replaced by other equivalent or features with similar purposes. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0024] Such asFigure 1 As shown, the structure of this embodiment includes a box body 1 made of metal. Charging interfaces 2 and high-current interfaces 7 are provided on two opposite side surfaces of the box body 1, and the two interfaces are connected through conductive posts 4.

[0025] In this embodiment, a layer of heat-conducting pad 5 is laid on the bottom inside the box body 1. The heat-conducting pad 5 is a rubber product, having good insulation performance and good heat transfer performance.

[0026] Two heat-dissipating structures 3 are provided on the heat-conducting pad 5. One heat-dissipating structure 3 is connected to one conductive post 4. Such a structure enables the heat generated on the conductive post 4 to be transferred to the heat-dissipating structure 3, then transferred from the heat-dissipating structure 3 to the heat-conducting pad 5, and the heat-conducting pad 5 disperses the heat to the box body 1, and the heat is dissipated outward from the surface of the box body 1.

[0027] In this embodiment, the heat-dissipating structure 3 is composed of a plurality of heat sinks, and the heat dissipation area of the conductive post 4 is increased through the surface of the heat sinks. The heat-dissipating structure 3 has two heat-dissipating functions. One is to transfer the heat to the box body 1 through heat transfer, and the other is to dissipate the heat to the air in the form of heat radiation through the heat sinks.

[0028] The space inside the box body 1 is a cavity. Heat radiation causes the air to heat up. When the temperature rise reaches a certain threshold, the air needs to be cooled down. In this embodiment, a breathing joint 6 is installed on the side surface of the box body 1. The breathing joint 6 can establish an air convection between the space inside the box body 1 and the space outside the box body 1, discharge the hot air inside the box body 1 to the outside of the box body, and at the same time suck the cold air outside the box body into the box body, thus completing the heat exchange of the air.

[0029] In this embodiment, the surface of the box body 1 made of metal has a good heat dissipation effect. At the same time, as the installation end of the charging plug, the box body needs to be fixed on other installation surfaces, and the contact between the installation surface and the box body can also play a heat dissipation effect.

[0030] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, and any new method or process step or any new combination disclosed.
