A dual-combination cooling resistor structure

Abstract

The present invention relates to a resistor structure with a dual-combination cooling method, comprising a base, a fan component, a resistor component, a water-cooled heat sink component, a hot air duct, and a cold air duct. The fan component and the resistor component are arranged side by side, with the fan component's air outlet facing the resistor component. The water-cooled heat sink component is arranged on one side of the resistor component. The resistor component is connected to the water-cooled heat sink component's air inlet via the hot air duct, and the water-cooled heat sink component's air outlet is connected to the fan component via the cold air duct. When the resistor component is operating, the fan component blows heat generated by the resistor component into the water-cooled heat sink component. The water-cooled heat sink component dissipates the hot air and converts it into cold air, which is then drawn into the fan component for circulation. Compared with existing technologies, the present invention utilizes both air-cooled and water-cooled circulation for heat dissipation, resulting in better heat dissipation and a wide range of applications.

Description

Technical Field

[0001] The present invention relates to a resistor structure, in particular to a resistor structure with a double-combination cooling mode. Background Art

[0002] With the increasing application of medium- and high-voltage variable-frequency systems in the marine industry, brake resistors are required to be installed inside the ship's cabin. Heat generated by the resistors must be dissipated internally, not allowed to escape into the cabin. This means that traditional air cooling is no longer sufficient. Water cooling, on the other hand, is only suitable for low-voltage variable-frequency systems. Therefore, a new resistor structure with a novel cooling method is needed. Summary of the Invention

[0003] The purpose of the present invention is to provide a dual-cooling resistor structure in order to overcome the above-mentioned defects in the prior art.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] A dual-combination cooling resistor structure includes a base and a fan component, a resistor component, a water-cooled heat sink component, a hot air duct, and a cold air duct arranged on the base. The fan component and the resistor component are arranged side by side with the fan component's air outlet facing the resistor component. The water-cooled heat sink component is arranged on one side of the resistor component. The resistor component is connected to the water-cooled heat sink component's air inlet through the hot air duct, and the water-cooled heat sink component's air outlet is connected to the fan component through the cold air duct.

[0006] When the resistance component is working, the fan component blows the heat generated by the resistance component into the water-cooled heat sink component. The water-cooled heat sink component dissipates the hot air and converts it into cold air. The cold air is sucked into the fan component to form a circulation.

[0007] The fan component, resistor component, water-cooled heat sink component and hot air duct are respectively fixed on the top of the base through a rectangular frame, and the fan component, resistor component, water-cooled heat sink component and hot air duct are compactly arranged to form a rectangular structure as a whole.

[0008] The resistance component air outlet and the water cooling component air inlet are located on the same vertical plane, and the hot air duct is located on the sides of the resistance component air outlet and the water cooling component air inlet and connects the resistance component air outlet and the water cooling component air inlet.

[0009] The hot air duct includes a straight section and arc sections arranged at both ends of the straight section, and the arc sections are respectively connected to the air outlet of the resistance component and the air inlet of the water-cooling heat dissipation component.

[0010] The water-cooled heat dissipation component includes a water-cooled heat dissipation box, a water inlet pipe, a water outlet pipe and a heat dissipation pipe. The opposite sides of the heat dissipation box are respectively the air inlet and the air outlet of the water-cooled heat dissipation component. The air inlet of the water-cooled heat dissipation component is connected to the resistance component, and the air outlet of the water-cooled heat dissipation component is connected to the fan component. The heat dissipation pipe is arranged in the water-cooled heat dissipation box, the water inlet pipe is connected to the water inlet of the heat dissipation pipe, and the water outlet of the heat dissipation pipe is connected to the water outlet pipe.

[0011] The cold air duct is a right-angle bent structure, and both ends of the cold air duct are respectively connected to the air outlet of the water-cooled heat dissipation component and the fan component.

[0012] A junction box for electrical wiring is also provided on the side of the fan component and the resistor component.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] (1) The present invention utilizes a fan component for air cooling and heat dissipation, and simultaneously utilizes a water cooling component for water cooling. The two methods are combined to form an air-cooled and water-cooled circulating heat dissipation. The heat of the resistor component can be consumed by the entire dual-combination cooling method resistor structure itself, without considering whether other precision equipment in the same space will be affected, and without reserving a certain safety distance;

[0015] (2) The present invention has a compact structure and is suitable for use in low-voltage, medium-voltage, and high-voltage frequency conversion systems. It has a flexible installation location and is suitable for cabins and decks, and has a wide range of applications.

[0016] (3) The two ends of the hot air duct of the present invention are arranged in an arc shape, which can effectively guide the hot air to flow from the resistance component to the water-cooled heat dissipation component, accelerate the circulation, and improve the heat dissipation effect.

[0022] like Figure 1As shown, a dual-combination cooling mode resistor structure includes a base 6 and a fan component 1, a resistor component 2, a water-cooled heat sink component 3, a hot air duct 5 and a cold air duct 4 arranged on the base 6. The fan component 1 and the resistor component 2 are arranged side by side and the air outlet of the fan component 1 faces the resistor component 2. The water-cooled heat sink component 3 is arranged on one side of the resistor component 2. The resistor component 2 is connected to the air inlet of the water-cooled heat sink component 3 through the hot air duct 5, and the air outlet of the water-cooled heat sink component 3 is connected to the fan component 1 through the cold air duct 4. When the resistor component 2 is working, the fan component 1 blows the heat emitted by the resistor component 2 into the water-cooled heat sink component 3. The water-cooled heat sink component 3 dissipates the hot air and converts it into cold air. The cold air is sucked into the fan component 1 to form a circulation.

[0023] The fan component 1, the resistor component 2, the water-cooled heat sink component 3 and the hot air duct 5 are respectively fixed on the top of the base 6 through a rectangular frame, and the fan component 1, the resistor component 2, the water-cooled heat sink component 3 and the hot air duct 5 are compactly arranged to form a rectangular structure as a whole. The structure is compact and suitable for application in low-voltage, medium-voltage and high-voltage frequency conversion systems. The installation location is more flexible and is suitable for cabins and decks. It has a wide range of applications.

[0024] The fan component 1 adopts a fan, the air outlet of the resistor component 2 and the air inlet of the water-cooled heat sink component 3 are located on the same vertical plane, and the hot air duct 5 is located on the side of the air outlet of the resistor component 2 and the air inlet of the water-cooled heat sink component 3 and connects the air outlet of the resistor component 2 and the air inlet of the water-cooled heat sink component 3. The hot air duct 5 includes a straight section and arc sections arranged at both ends of the straight section, and the arc sections respectively connect the air outlet of the resistor component 2 and the air inlet of the water-cooled heat sink component 3. The two ends of the hot air duct 5 are arranged in an arc shape, which can guide the flow of hot air, speed up circulation, and improve the heat dissipation effect. Figure 1 In the figure, the hot air duct 5 is arranged in an outwardly convex rectangular sealed frame.

[0025] The water-cooled heat sink 3 includes a water-cooled heat sink housing, a water inlet pipe, a water outlet pipe, and a heat sink. Opposite sides of the heat sink housing respectively house the air inlet and air outlet of the water-cooled heat sink 3. The air inlet of the water-cooled heat sink 3 is connected to the resistor component 2, and the air outlet of the water-cooled heat sink 3 is connected to the fan component 1. The heat sink is disposed within the water-cooled heat sink housing, with the water inlet pipe connected to the heat sink water inlet, and the heat sink water outlet connected to the water outlet pipe. The water inlet and outlet pipes are provided with a water inlet flange 8 and a water outlet flange 9, respectively.

[0026] The cold air duct 4 is a right-angled bent structure, and both ends of the cold air duct 4 are connected to the air outlet of the water-cooled heat dissipation component 3 and the fan component 1 respectively.

[0027] A junction box 7 for electrical wiring is also provided on the side of the fan component 1 and the resistor component 2.

[0028] This device combines air and water cooling. Resistor 2 uses forced air cooling to rapidly blow heat generated by the resistor into the water-cooled heat sink 3. This heat sink 3 then uses water cooling to convert the hot air into cold air, which is then drawn into the fan, completing a complete cycle. The heat generated by resistor 2 is self-dissipated, eliminating the need to maintain a safe distance from other precision equipment in the same space and significantly reducing floor space.
