Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of all-in-one electrically controlled flow channel structure, specifically an all-in-one electrically controlled flow channel structure. Background Technology
[0002] The all-in-one electronic control cooling system suffers from insufficient coolant distribution and the inability to reposition electronic components such as DC-DC converters and DC-AC converters. Therefore, the cooling channel structure needs to be optimized. However, considering the cooling channel layout, a complete redesign of the cooling channel is not feasible. Instead, the cooling channel needs to be optimized to meet the flow requirements of the components. By optimizing the cooling channel structure, the coolant distribution of the electronic control system can be satisfied. Considering that the all-in-one channel is for cooling electronic components such as DC-DC converters and DC-AC converters to keep them at their optimal operating temperature, an optimized all-in-one electronic control channel design is proposed. The structure of the all-in-one electronic control cooling channel is optimized and modified to meet the flow requirements of each component and prevent the occurrence of local dead zones.
[0003] Before the optimization of the all-in-one electronically controlled flow channel structure, there were local dead zones. Due to the low-pressure backflow, the pressure loss also increased, which was not conducive to the selection of water pumps. After optimization, the local dead zones were eliminated, and the pressure loss was reduced, which is beneficial to the overall cost reduction and efficiency improvement of the system.
[0004] This application optimizes the flow of coolant during operation by adjusting the internal flow channel structure design of the all-in-one electronic control cooling system, thereby meeting the flow distribution requirements of related components of the cooling system. The flow channel is free of dead zones, preventing local dead zones from affecting the performance of the electronic control system and meeting the cooling requirements of related components of the electronic control system. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a multi-functional electrically controlled flow channel structure, which solves the problem of local dead zones existing in the original multi-functional electrically controlled flow channel structure. Due to low-pressure backflow, pressure loss also increases, which is not conducive to water pump selection. This invention prevents the occurrence of local dead zones that affect the performance of the electrical control system.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional electrically controlled flow channel structure, comprising: The all-in-one electronically controlled flow channel structure is equipped with DCAC and DCDC. The flow channel guide ribs are formed on the all-in-one electronically controlled flow channel structure; The needle-fin structure is set on the all-in-one electronically controlled flow channel structure; The right-angled structure of the DC-CDC corresponding area at the inlet of the multi-in-one electronically controlled flow channel structure is set to a rounded transition structure. The all-in-one electronically controlled flow channel structure has rounded corners in the corresponding area of DCAC.
[0007] Preferably, the all-in-one electronically controlled flow channel structure allows coolant to flow in through the coolant inlet, and the coolant flows through the all-in-one electronically controlled flow channel structure and is discharged from the coolant outlet for circulation.
[0008] Preferably, the coolant is composed of water and ethanol.
[0009] Preferably, a SiC inverter is disposed above the needle-fin structure.
[0010] Preferably, one end of the all-in-one electronically controlled flow channel structure is provided with a coolant outlet, which is located at the end near the needle-fin structure.
[0011] Preferably, a coolant inlet is provided at the other end of the all-in-one electronically controlled flow channel structure.
[0012] Its beneficial effects are as follows: 1. In this all-in-one electronically controlled flow channel structure, the right-angle structure in the DC / DC corresponding area at the flow channel inlet is changed to a rounded transition structure with a length of 85mm. This eliminates the low-pressure backflow area generated by the original flow channel. The DC / AC corresponding area of the all-in-one electronically controlled flow channel structure is changed to a rounded corner with a radius of R46.5, which follows the fluid flow and works in conjunction with the guide channel to guide the flow.
[0013] 2. This all-in-one electronic control flow channel structure eliminates the low-speed zone in the flow channels corresponding to electronic components such as DCAC and DCDC, and the fluid completely covers the corresponding flow channels of DCAC and DCDC, eliminating local dead zones. The overall pressure loss is 8KPa. The structural improvement eliminates local dead zones, improves the utilization rate of coolant, and reduces flow channel pressure loss. It also facilitates the cost reduction of water pump selection, which is beneficial to the overall cost reduction and efficiency improvement of the system, and meets the cooling requirements of related components of the electronic control system.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0019] This utility model discloses an all-in-one electrically controlled flow channel structure. According to the appendix Figure 1 and Figure 2 As shown, it includes: The multi-in-one electronically controlled flow channel structure 1 is equipped with DCAC and DCDC respectively; Flow guide rib 2 is formed on the multi-in-one electronically controlled flow channel structure 1; Needle-fin structure 3 is disposed on the multi-in-one electrically controlled flow channel structure 1; The right-angle structure of the DC-DC corresponding area at the inlet of the multi-functional electronically controlled flow channel structure 1 has been changed to a rounded transition structure. Specifically, the length of the rounded transition structure is 85mm, which eliminates the low-pressure backflow area generated by the original flow channel.
[0020] The multi-functional electronically controlled flow channel structure 1 has rounded corners in the corresponding DCAC area. Specifically, the rounded corners are R46.5, which facilitates fluid flow and works in conjunction with the flow guide channel to guide the flow. Coolant outlet 4 is located at one end of the multi-in-one electronically controlled flow channel structure 1, and coolant outlet 4 is located at one end near the needle fin structure 3. Coolant inlet 5 is located at the other end of the all-in-one electronically controlled flow channel structure 1.
[0021] Coolant circulates through the all-in-one electronically controlled flow channel structure 1, coolant outlet 4, and coolant inlet 5 to dissipate heat from the DCAC, DCDC, and SiC inverters on the all-in-one electronically controlled flow channel structure 1.
[0022] Specifically disclosed, the coolant is diverted from the coolant inlet 5 by the flow channel guide 2 to ensure uniform distribution of coolant in the main flow area. The inner flow channel is fully filled with coolant. After passing through electronic components such as DC-DC, DC-AC, and SiC inverters for heat exchange, the coolant flows out from the coolant outlet 4.
[0023] The all-in-one electronically controlled flow channel structure 1 receives coolant through the coolant inlet 5, and the coolant flows out of the all-in-one electronically controlled flow channel structure 1 and is discharged from the coolant outlet 4 for circulation.
[0024] The coolant is composed of water and ethanol, with a composition of 50% water and 50% ethanol, and the flow rate is set to 10 L / min.
[0025] Furthermore, coolant at a temperature of 65°C flows in through coolant inlet 5 and is diverted by flow channel guide ribs 2 to ensure uniform distribution of coolant in the main flow area. The inner flow channel is fully filled with coolant. After passing through electronic components such as DC-DC converters with operating temperatures ≤85°C, DC-AC converters with operating temperatures ≤85°C, and SiC inverters with operating temperatures ≤150°C for heat exchange, the coolant flows out through coolant outlet 4.
[0026] The operating temperature of DC-DC inverters is ≤85℃, the operating temperature of DC-AC inverters is ≤85℃, and the operating temperature of SiC inverters is ≤150℃.
[0027] A SiC inverter is installed above the needle-fin structure 3.
[0028] It is particularly important to note that the SiC inverter area is cooled by the finned structure 3, and the fluid distribution in the SiC inverter area is uniform with no local dead zones. Subsequent structures will not be optimized for this substructure.
[0029] According to the appendix Figure 3-5 As shown, the maximum velocity of the flow channel is 1.22 m / s. Low-speed zones appear at the multi-in-one electronic control flow channel structure 1 corresponding to electronic components such as DCAC and DCDC. After the fluid passes through the coolant inlet 5 and the bend, low-pressure zones are generated locally in the DCDC and DCAC, resulting in the coolant not completely covering the multi-in-one electronic control flow channel structure 1, creating local dead zones, which is not conducive to heat dissipation of electronic components. In the existing technology, due to the presence of local low-pressure areas, the overall pressure loss is 9 kPa.
[0030] According to the appendix Figure 6 and Figure 7As shown, the maximum velocity of the coolant flow channel is 1.26 m / s, which is 0.04 m / s higher than before optimization. The low-speed zone at the flow channel corresponding to electronic components such as DCAC and DCDC disappears, and the fluid completely covers the flow channels corresponding to DCDC and DCAC, eliminating local dead zones.
[0031] The overall pressure loss is 8 kPa. The structural improvements have eliminated local dead zones, improved the utilization rate of coolant, reduced flow channel pressure loss, facilitated the selection of water pumps to reduce costs, and contributed to the overall cost reduction and efficiency improvement of the system, while meeting the cooling requirements of related components of the electronic control system.
[0032] Working principle: Coolant at 65℃ flows in through coolant inlet 5, and is diverted by flow channel guide rib 2 to ensure uniform distribution of coolant in the main flow area. The inner flow channel is fully filled with coolant. After passing through electronic components such as DC-DC, DC-AC, and SiC inverter for heat exchange, the coolant flows out through coolant outlet 4. The SIC inverter area is cooled by the finned structure 3, and the coolant circulates through the multi-in-one electronic control flow channel structure 1, the coolant outlet 4 and the coolant inlet 5 to cool the DCAC, DCDC and SIC inverters on the multi-in-one electronic control flow channel structure 1.
[0033] The right-angle structure of the DC-DC corresponding area at the inlet of the all-in-one electronically controlled flow channel structure 1 has been changed to a rounded transition structure with a length of 85mm, which eliminates the low-pressure backflow area generated by the original flow channel.
[0034] The multi-functional electronically controlled flow channel structure 1 is modified to have R46.5 rounded corners in the corresponding area of DCAC, which facilitates the fluid flow and works in conjunction with the flow guide channel to guide the flow.
