Description

Technical Field

[0001] This utility model belongs to the technical field of simulated load equipment, and specifically relates to a water-cooled heat exchange component for simulating loads. Background Technology

[0002] In existing data centers, various types of target devices (such as servers) generate a significant amount of heat during operation. Excessive heat can cause a sharp drop in the performance of these devices, placing high demands on the data center's heat dissipation or cooling capabilities. Before a data center's heat dissipation or cooling system is officially put into use, it typically needs to be tested to ensure it meets certain requirements. For example, maintaining the data center's indoor temperature at a certain level while several target devices are operating normally. However, using actual target devices for testing could lead to unnecessary losses and waste. In reality, it's difficult to achieve the testing objectives with actual target devices because their power and temperature are often uncontrollable. Therefore, a simulated load chamber is needed to mimic the heat generated by the target devices during the aforementioned testing process. Patents such as CN205607665U, CN101587136A, and CN101587137A disclose related technical solutions.

[0003] In existing technologies, the analog loads in analog load boxes typically use PTCs, which are cooled by accompanying air cooling. When the cooling is insufficient, the resistance of the PTC increases sharply with the temperature, resulting in a decrease in power and making it impossible to operate at a constant power.

Detailed Implementation

[0020] See appendix Figure 1-6 This utility model provides a water-cooled heat exchange component for simulating loads, including a heat collector plate assembly, at least two layers of heat exchange tubes 1 disposed in the heat collector plate assembly, a PTC resistor element assembly located between two adjacent layers of heat exchange tubes 1, and matching inlet pipe 2, outlet pipe 3, and connecting pipe 4 connecting the two adjacent layers of heat exchange tubes 1. Heat exchange tubes 1 are disposed on both the upper and lower sides of each layer of PTC resistor element assembly to ensure heat exchange efficiency and achieve the effect of dissipating heat from the PTC resistor element 10.

[0021] The heat collector assembly serves to receive the heat emitted by the PTC resistor element assembly and exchange heat with the heat exchange tube 1 and the air. The heat collector assembly includes a first heat collector plate 5, a second heat collector plate 6, at least one intermediate heat collector plate 7 located between the first and second heat collector plates 5 and 6, and connecting bolts 8 and matching connecting nuts 9 passing through the first heat collector plate 5, the intermediate heat collector plate 7, and the second heat collector plate 6. PTC resistor elements are installed between adjacent intermediate heat collector plates 7, between an intermediate heat collector plate 7 and the first heat collector plate 5, and between an intermediate heat collector plate 7 and the second heat collector plate 6. In this embodiment, an intermediate heat collector plate 7 is provided, with a layer of PTC resistor elements installed above and below the intermediate heat collector plate 7. A matching mounting plate is provided on the heat collector plate. All heat collector plates, PTC resistor elements, and heat exchange tube 1 are combined into a module using the connecting bolts 8 and connecting nuts 9, facilitating installation and disassembly. The inlet pipe 2 is connected to the inlet of the heat exchange tube 1 at the bottom layer, and the outlet pipe 3 is connected to the outlet of the heat exchange tube 1 at the top layer. The outlet of the heat exchange tube 1 at the bottom layer in the two adjacent layers is connected to the inlet of the heat exchange tube 1 at the top layer through the connecting pipe 4.

[0022] The PTC resistor element assembly includes multiple PTC resistor elements 10 arranged along the length of the intermediate heat collector plate 7. The number of resistor elements is determined according to the heat exchange capacity. In this embodiment, each layer of the PTC resistor element assembly includes 15 PTC resistor elements 10.

[0023] See appendix Figure 5 and 6To facilitate the installation and positioning of the PTC resistor 10, positioning grooves 7-1 for positioning one or more PTC resistors 10 are provided on the top and bottom surfaces of the middle heat collector plate 7. In this embodiment, the positioning grooves 7-1 on both sides can only position one PTC resistor 10 to leave room for bolt installation, while the positioning groove 7-1 in the middle can position multiple PTC resistors 10.

[0024] See appendix Figure 5 and 6 The intermediate heat collector plate 7 includes an upper heat collector plate 7-2, a lower heat collector plate 7-3, and connecting screws 11 connecting the upper heat collector plate 7-2 and the lower heat collector plate 7-3. A heat exchange tube limiting groove 7-4 for limiting the heat exchange tube 1 is provided between the upper heat collector plate 7-2 and the lower heat collector plate 7-3. The heat exchange tube limiting grooves 7-4 of the two heat collector plates cooperate to form a limiting cavity to limit the heat exchange tube 1.

[0025] See appendix Figure 3 and 4 The first heat-collecting plate 5 and the second heat-collecting plate 6 are respectively provided with a first limiting groove 5-1 and a second limiting groove 6-1 for limiting the heat exchange tube 1. Since the diameter of the tube in the heat exchange tube 1 is greater than the depth of the limiting groove, the part of the heat exchange tube 1 located in the first limiting groove 5-1 or the second limiting groove 6-1 is pressed into a shape that matches the cross-section of the limiting groove.

[0026] See appendix Figure 1 and 2 To facilitate the installation of the connecting pipe 4, the liquid inlet and liquid outlet of all heat exchange pipes 1 are located on the same side of the heat collector plate assembly.

[0027] In practical use, the water-cooled heat exchange component of this invention is used in conjunction with a water-cooling system in the computer room. The water-cooling system provides coolant to the water-cooled heat exchange component. The coolant flows into the lower heat exchange tube 1 through the inlet pipe 2 and flows upward through each layer of heat exchange tube 1 before returning to the water-cooling system through the outlet pipe 3. During this process, the heat generated by the PTC resistor element is promptly removed to ensure that it can operate at a constant power.
