Technical Field
[0001] This utility model relates to the field of liquid-cooled load technology, specifically a liquid-cooled load device. Background Technology
[0002] With the widespread adoption and development of electronic devices, especially power electronic devices, in various industrial applications, the power density of load devices is increasing, and the heat generated is also increasing. Traditional cooling methods, such as air cooling or wind cooling, can still meet the requirements in some low-power applications, but in high-power, high-load operating environments, especially in load devices with strict thermal management requirements, the efficiency of traditional cooling methods is becoming increasingly inadequate and unable to meet the growing heat dissipation demands.
[0003] Liquid cooling technology, due to its high thermal conductivity, has become an important solution for thermal management of high-power load equipment. Liquid cooling systems remove heat from the equipment's interior through liquid flow, exhibiting good thermal efficiency and stability. Therefore, liquid-cooled load equipment is widely used in power electronics, testing equipment, and communication equipment. However, existing liquid-cooled load equipment still has some problems, such as uneven coolant flow, unstable cooling effect, complex structure, and inconvenient maintenance. These problems affect the overall performance and service life of the equipment. Utility Model Content

[0005] The technical solution adopted by this utility model to achieve the above objectives is as follows: a liquid-cooled load device, comprising a protective housing, a load housing, and a resistor unit. The protective housing serves as the outer shell of the device, providing physical protection and ensuring the safety and stability of the internal components. The load housing is fixedly connected inside the protective housing. The resistor unit is fixedly installed inside the load housing, providing support and enclosure to ensure effective cooling of the resistor unit. The resistor unit has its terminals extending out of the load housing and distributed on one side. An inlet housing and an outlet housing are fixedly connected to the other side of the load housing.

An outlet pipe is fixedly connected to the end face of the outlet shell, and the outlet pipe passes through the protective housing and connects to the outlet quick connector. In this invention, the inlet quick connector and outlet quick connector are used to quickly connect the inlet and outlet pipes. In use, the liquid enters the inlet shell through the inlet pipe, and then is introduced into the load shell through the inlet shell, thereby cooling the resistor unit inside the load shell. After that, the liquid flows out of the outlet shell and is finally discharged through the outlet pipe.
[0006] In the above technical solution, the resistor unit includes a U-shaped metal outer tube, a resistor core, a connecting post, and a terminal post.

The outer end of the connecting post is fixedly connected to the terminal post, which passes through the connecting post and is connected to the resistor core inside the U-shaped metal outer tube.
[0007] In the above technical solution, a first partition plate is fixedly connected inside the load shell on the opposite side of the liquid inlet shell. A liquid inlet channel is formed between the first partition plate and the inner wall of the load shell. The liquid inlet channel is connected to the liquid inlet shell. A plurality of water inlet holes are provided on the first partition plate. The density of the water inlet holes on the first partition plate gradually increases from the side closer to the liquid inlet shell to the side farther away from the liquid inlet shell. A buffer plate, a first water flow dispersion plate and a first mounting plate are fixedly connected in sequence inside the load shell on the side of the first partition plate. A plurality of evenly spaced vertical through holes are provided on the buffer plate. A bent guide plate is fixedly connected in each of the vertical through holes.
[0008] In the above technical solution, a second partition plate is fixedly connected inside the load shell on one side of the liquid outlet shell. A liquid outlet channel is formed between the second partition plate and the inner wall of the load shell. The liquid outlet channel is connected to the liquid outlet shell. A plurality of water outlet holes are opened on the second partition plate.

A plurality of evenly spaced vertical guide holes are opened on the inclined guide plate. An inclined guide plate is fixedly connected in each of the vertical guide holes. The inclined guide plates are inclined towards the direction of the water outlet holes with a larger density.
[0009] In the above technical solution, a water-cooled chamber is formed between the first mounting plate and the second mounting plate. The U-shaped metal outer tube of the resistor unit is evenly arranged in the water-cooled chamber. Several evenly spaced support plates are fixedly connected in the water-cooled chamber. The U-shaped metal outer tube is connected through the support plate. The two ends of the support plate are respectively vertically connected to the first mounting plate and the second mounting plate.
[0010] The beneficial effects of this utility model are:

The modular design of the liquid cooling system allows operators to quickly inspect and replace parts, reducing downtime and maintenance costs.
[0013] 3. Uniform liquid flow: By setting inlet and outlet holes of different densities, and in combination with the functions of guide plates and dispersion plates, the flow of liquid in the load shell is effectively guided, the flow rate and flow are more uniform, avoiding the problem of uneven cooling, thereby improving the overall cooling efficiency.
[0014] 4. Enhanced Mechanical Support: The resistor unit adopts a U-shaped metal outer tube structure, which is fixed by support plates and connecting columns to ensure the mechanical stability of the resistor unit.

[0027] Please see Figure 1-8 A liquid-cooled load device includes a protective housing 1, a load housing 2, and a resistor unit 3. The protective housing 1 serves as the outer shell of the device, providing physical protection and ensuring the safety and stability of the internal components. The load housing 2 is fixedly connected inside the protective housing 1. The resistor unit 3 is fixedly connected inside the load housing 2, providing support and enclosure to ensure effective cooling of the resistor unit 3. The resistor unit 3 has terminals 104 that extend out of the load housing 2 and are distributed on one side. The other side of the load housing 2 is fixedly connected to an inlet housing 4 and an outlet housing 5. The inlet housing 4 and the outlet housing 5 are respectively located on... At both ends of the load housing 2, the end face of the liquid inlet housing 4 is fixedly connected to the liquid inlet pipe 6. After the liquid inlet pipe 6 passes through the protective housing 1, it is connected to the liquid inlet quick connector 7. The end face of the liquid outlet housing 5 is fixedly connected to the liquid outlet pipe 8.

In this utility model, the liquid inlet quick connector 7 and the liquid outlet quick connector 9 are used to quickly connect the liquid inlet and liquid outlet pipes 8, respectively. When in use, the liquid enters the liquid inlet housing 4 through the liquid inlet pipe 6, and then is introduced into the load housing 2 through the liquid inlet housing 4, thereby cooling the resistor unit 3 inside the load housing 2. After that, the liquid flows out of the liquid outlet housing 5 and is finally discharged through the liquid outlet pipe 8.
[0028] In one embodiment of this utility model, the resistor unit 3 includes a U-shaped metal outer tube 101, a resistor core 102, a connecting post 103, and a terminal post 104. The resistor core 102 is disposed inside the U-shaped metal outer tube 101, and an insulating material is filled between the resistor core 102 and the U-shaped metal outer tube 101. The ends of the U-shaped metal outer tube 101 are respectively fixedly connected to the connecting post 103, and the connecting post 103 is embedded in the outer wall of one side of the load housing 2. The outer end of the connecting post 103 is fixedly connected to the terminal post 104, and the terminal post 104 passes through the connecting post 103 and is connected to the resistor core 102 inside the U-shaped metal outer tube 101. The U-shaped metal outer tube 101 has good thermal conductivity, wraps around and protects the resistor core 102, and provides necessary support structure. The resistor core 102 is the core component of the resistor unit 3. It is made of a high-resistivity material (such as a metal alloy) and generates heat during operation. The insulating material is used to avoid direct electrical contact between the resistor core 102 and the outer tube, and at the same time helps to conduct heat. The connecting post 103 is used to realize the relative connection between the resistor unit 3 and the load housing 2, and at the same time provides mechanical support for the resistor unit 3. The terminal post 104 is located outside the load housing 2 and serves to connect to the external circuit.
[0029] In one embodiment of this utility model, a first partition plate 201 is fixedly connected inside the load shell 2 on the opposite side of the liquid inlet shell 4. A liquid inlet channel 202 is formed between the first partition plate 201 and the inner wall of the load shell 2, and the liquid inlet channel 202 is connected to the liquid inlet shell 4. A plurality of water inlet holes 203 are provided on the first partition plate 201, and the density of the water inlet holes 203 on the first partition plate 201 gradually increases from the side closer to the liquid inlet shell 4 to the side farther away from the liquid inlet shell 4. A buffer plate 204, a first water flow dispersion plate 205, and a first safety plate are fixedly connected in sequence inside the load shell 2 on the side of the first partition plate 201. The mounting plate 206 and buffer plate 204 have several evenly spaced vertical through holes 207, and each vertical through hole 207 is fixedly connected to a bent guide plate 208.

Inside the load housing 2 on one side, an inclined guide plate 304, a second water flow dispersion plate 305, and a second mounting plate 306 are sequentially fixedly connected. The inclined guide plate 304 has several evenly spaced vertical guide holes 307, each with an inclined guide plate 308 fixedly connected to it. The inclined guide plates 308 are inclined towards the outlet holes 303 with higher density. During operation, liquid flows from the inlet housing 4 into the inlet channel 202, then flows evenly through the gradually increasing density inlet holes 203 on the first partition plate 201, and finally the buffer plate 204 buffers and slows down the water flow. The uniformity of water flow distribution is further improved by the first water flow dispersion plate, so that the water flow can flow evenly through the water-cooled chamber 401 formed between the first mounting plate 206 and the second mounting plate 306 to effectively cool the resistor unit 3. Then the liquid flows through the second water flow dispersion plate 305, so that the water flows out evenly. Then the direction of water flow is guided by the inclined guide plate 304 to prevent the water flow from gathering directly towards the liquid outlet shell 5, thereby affecting the uniformity of water flow inside the load shell 2. Then the water flows evenly into the liquid outlet channel 302 through the second partition plate 301, and finally the liquid flows out through the liquid outlet shell 5.
[0030] In this utility model, both the first mounting plate 206 and the second mounting plate 306 are mesh plates.
[0031] In one embodiment of this utility model, a water-cooled chamber 401 is formed between the first mounting plate 206 and the second mounting plate 306 to accommodate the mounting resistor unit 3 and to cool the resistor unit 3 by the flowing liquid. The U-shaped metal outer tube 101 of the resistor unit 3 is evenly arranged in the water-cooled chamber 401. Several evenly spaced support plates 402 are fixedly connected in the water-cooled chamber 401. The U-shaped metal outer tube 101 is connected through the support plate 402. The two ends of the support plate 402 are respectively vertically connected to the first mounting plate 206 and the second mounting plate 306. The support plate 402 is used to support and fix the U-shaped metal outer tube 101, and at the same time ensures that the coolant can flow evenly in the water-cooled chamber 401 to avoid local overheating or insufficient cooling.
