The present embodiment relates to a converter.
As electric devices of automobiles, engine electric devices (starting device, ignition device, and charging device) and lighting device are common, but in recent years, as vehicles are more electronically controlled, most systems including chassis electric devices are becoming electric and electronic.
Various electric components such as lamps, audio, heaters, and air conditioners being installed in automobiles receive power from the battery when the car is stopped and receive power from the generator when driving, and at this time, the power generation capacity of the 14V power system is used as a normal power supply voltage.
Recently, along with the development of the information technology industry, various new technologies (motorized power steering, Internet, and the like) for the purpose of increasing the convenience of automobiles are being adopted to vehicles, and in the future, it is expected that the development of new technologies that can utilize the current automobile system to the maximum will continue.
A hybrid electric vehicle (HEV), regardless of soft or hard type, is equipped with a DC-DC converter for supplying an electric load (12V). In addition, the DC-DC converter, which acts as a generator (alternator) of a general gasoline vehicle, supplies a voltage of 12V for the electric load by reducing the high voltage of the main battery (usually a high-voltage battery of 144V or more).
A DC-DC converter refers to an electronic circuit device that converts DC power of a certain voltage to DC power of another voltage, and is used in various fields such as automobile electronic products and television sets.
An outer shape of a converter is formed by a housing. A plurality of electronic components is disposed inside the housing. Electronic components generate heat by being driven. Heat may cause overload of electronic components, causing a failure in a setting function and causing failure. Accordingly, the converter includes a refrigerant pipe for heat dissipation of the components. The refrigerant pipe includes a flow path through which the refrigerant flows, and a refrigerant inlet and a refrigerant outlet are formed at both ends, respectively.
Accordingly, a refrigerant supply unit for providing a refrigerant through a flow path and a refrigerant recovery unit for recovering the refrigerant flowing through the flow path are coupled to both ends of the refrigerant pipe. A structure for preventing arbitrary rotation is required in connection between a refrigerant supply unit and a refrigerant inlet, a refrigerant outlet and a refrigerant recovery unit, that is, different components.
The present embodiment is intended to provide a converter capable of being firmly coupled to each other by preventing arbitrary rotation between a refrigerant pipe and components being coupled to the refrigerant pipe, thereby facilitating refrigerant inflow and discharge.
A converter according to the present embodiment comprises: a housing; a refrigerant pipe being coupled to the housing and having end portions being protruded from an outer surface of the housing; and a bracket being coupled to an outer surface of the refrigerant pipe, wherein the bracket includes: a first body encompassing a portion of an outer surface of the refrigerant pipe; and a second body being hinge-coupled to the first body and encompassing the other portion of an outer surface of the refrigerant pipe, and wherein the first body or the second body includes a protruding part being protruded from an outer surface thereof.
The first body includes: a first body part, in the shape of an arc, being coupled to an outer surface of the refrigerant pipe; and a first coupling part being disposed outside the first body part and coupled to an outer surface of the housing, wherein the protruding part may be disposed on an outer surface of the first body portion.
The second body includes: a second body part, in the shape of an arc, being coupled to an outer surface of the refrigerant pipe; and a second coupling part being disposed outside the second body part and coupled to an outer surface of the housing, wherein the protruding part may be disposed on an outer surface of the first body part.
The first body includes a first hinge part being disposed outside the first body part; the second body includes a second hinge part being disposed outside the second body part; and a hinge pin whose both ends are coupled to the first hinge part and the second hinge part may be included.
The protruding part includes: a first protruding part being disposed on an outer surface of the first body part; and a second protruding part being disposed on an outer surface of the second body part, wherein the first protruding part and the second protruding part may be disposed symmetrically about the refrigerant pipe.
The first coupling part includes a first hole penetrating from an inner surface to an outer surface; the housing includes a first screw hole facing the first hole; and a screw penetrating the first hole and being coupled to the first screw hole may be included.
The first coupling part may include a second hole penetrating from an inner surface to an outer surface, wherein the housing may include a rib being protruded from an outer surface and coupled to the second hole.
The second coupling part includes a third hole penetrating from the inner surface to the outer surface, wherein the housing includes a second screw hole facing the third hole, and wherein a screw penetrating the third hole and being coupled to the second screw hole may be included.
On an outer surface of the first coupling part, a step region in a shape being more recessed than other regions is included; the second coupling part is coupled to the step region and includes a third hole facing the first hole; and the screw may penetrate through the third hole and the first hole to be coupled to the first screw hole.
The refrigerant pipe may include a guide being formed to have a larger cross-sectional area than other regions, wherein the bracket may be disposed between the guide and an outer surface of the housing.
Through the present embodiment, a structure that prevents the rotation of the refrigerant pipe is implemented using a bracket so that there is an advantage in that the coupling between the refrigerant pipe and other components can be firmly maintained in a region where the refrigerant is supplied or recovered.
In addition, since a structure that prevents the rotation of the refrigerant pipe can be implemented with only a bracket regardless of the type of refrigerant pipe, there is an advantage in that the degree of freedom in design is increased.

The bracket 300 may include a hinge pin (not shown) having one end coupled to the first hinge part 326 and the other end coupled to the second hinge part 346. Accordingly, the first body 310 or the second body 330 may rotate about the hinge pin.

According to the above structure, a structure that prevents the rotation of the refrigerant pipe is implemented using a bracket so that there is an advantage in that the coupling between a refrigerant pipe and other components can be maintained firmly in a region where refrigerant is supplied or recovered.
In addition, since a structure that prevents the rotation is implemented only with a bracket 300 regardless of the type of the refrigerant pipe 300, there is an advantage in that the degree of freedom in design can be increased.

For an example, when viewed from the side surface of the converter, the first protruding part 416 may be disposed in a direction toward the 12 o'clock on an outer surface of the first body part 412. The first protruding part 416 is protruded more outward than other regions so that when the refrigerant supply unit is coupled to the refrigerant inlet or the refrigerant recovery unit is coupled to the refrigerant outlet, it is possible to prevent the refrigerant supply unit or the refrigerant recovery unit from randomly rotating against the refrigerant inlet or the refrigerant outlet. For an example, the refrigerant supply unit or the refrigerant recovery unit may include a groove into which the first protruding part 416 is coupled.

Meanwhile, the first coupling part 420 may include a second hole 422 penetrating from one surface to the other surface. Additionally, a rib 137 being coupled to the second hole 422 may be formed on a side surface of the housing facing the second hole 422.

For an example, when viewed from the side surface of the converter, the second protruding part 436 may be disposed in a direction toward the 6 o'clock on an outer surface of the second body part 432. The second protruding part 436 may be disposed symmetrically with the first protruding part 416 with respect to the refrigerant pipe. The second protruding part 436 is protruded more outward than other regions so that when the refrigerant supply unit is coupled to the refrigerant inlet or the refrigerant recovery unit is coupled to the refrigerant outlet, it is possible to prevent the refrigerant supply unit or the refrigerant recovery unit from randomly rotating against the refrigerant inlet or the refrigerant outlet. For an example, the refrigerant supply unit or the refrigerant recovery unit may include a groove into which the second protruding part 436 is coupled.

The second coupling part 440 may be disposed outside the second body part 432. The second coupling part 440 may be screw-coupled to a side surface of the housing. A hole 138 into which the second coupling part 440 is screw-coupled may be formed on a side surface of the housing. In addition, the second coupling part 440 may penetrate through an inner surface from an outer surface to form a third hole 442 facing the hole 138 and the first hole 428 of the first coupling part 420. Therefore, when the bracket 400 is coupled to a side surface of the housing, the screw may penetrate through the third hole 442 and the first hole 428 to be screw-coupled into the hole 138 of the housing.
