Description
Technical Field
[0001] This utility model belongs to the technical field of water-heated PTC assembly, and particularly relates to a general-purpose aluminum profile structure WPTC assembly with longitudinally arranged flow channels. Background Technology
[0002] WPTC (Water-Driven PTC): This type of heater uses resistance to generate heat, but it heats the coolant. The heated coolant, in conjunction with an electric water pump, circulates in the vehicle's heater core, thus achieving a heating effect inside the vehicle. WPTC heaters are installed outside the air conditioning unit, offering advantages such as no risk of high-voltage leakage and high design flexibility. Furthermore, they require no modifications to the existing air conditioning unit, making them more popular and resulting in a higher vehicle installation rate.
[0003] Currently, new energy vehicle OEMs have significantly different requirements for WPTC assemblies, resulting in three main voltage platforms on the market: 350V, 600V, and 800V. The power requirements also vary even more, ranging from 3KW to 10KW. WPTC assemblies on the market are basically not interchangeable across different voltage and power platforms. Therefore, this utility model proposes a universal aluminum profile structure WPTC assembly with longitudinally arranged flow channels to solve the above problems. Utility Model Content

[0026] Please see Figures 1 to 3 This utility model provides a technical solution: a general-purpose aluminum profile structure WPTC assembly with longitudinal flow channel, including a front water chamber 1, a water chamber heater 2 and a control chamber 3; the water chamber heater 2 includes an outer water chamber profile 5, an inner water chamber profile 8 and a PTC heating element 7, the outer water chamber profile 5 covers the inner water chamber profile 8, there are multiple inner water chamber profiles 8, the multiple inner water chamber profiles 8 are evenly spaced along the extension direction of the outer water chamber profile 5, and a PTC heating element 7 is provided between every two inner water chamber profiles 8.
[0027] In this embodiment, the controller in the control room 3 supplies high voltage to the WPTC. The WPTC receives the vehicle command and starts to power the PTC heating pack 7 in the WPTC. The PTC heating pack 7 releases heat. At the same time, the coolant flows through the channel to carry away the heat released by the PTC heating pack 7. Then, it passes through the heater core and the battery pack to achieve the heating of the vehicle passenger compartment and the battery pack.
[0028] This general-purpose WPTC assembly consists of a front water chamber 1, a water chamber heater 2, and a control chamber 3, which are fastened together by extension screws 4, forming a transversely integrated sealed WPTC assembly; see reference Figure 3The water chamber heater 2 is provided with an outer water chamber profile 5, multiple inner water chamber profiles 8 and multiple PTC heating elements 7, which are arranged in a horizontally stacked structure. Finally, countersunk screws 6 are used to fasten and attach the components together. The multiple inner water chamber profiles 8 are evenly spaced along the extension direction (horizontal direction) of the outer water chamber profile 5. A PTC heating element 7 is provided between every two inner water chamber profiles 8, so that the heat of the PTC heating element 7 can be transferred out when the coolant passes through the inner water chamber profile 8.
[0029] This utility model, through its horizontally stacked structure of heating packs and aluminum profile water chambers, can achieve a full voltage range from 0V to 800V. The extruded aluminum profile water chambers can be adjusted in length, enabling a full power range from 1KW to 18KW.
[0030] For further details, please refer to Figure 1 The front water chamber 1 and the water chamber heater 2 are fixedly connected by an extension screw 4.
[0031] For further details, please refer to Figure 1 The water chamber heater 2 and the control chamber 3 are also fixedly connected by extension screws 4.
[0032] In this embodiment, the extended screw 4 makes the front water chamber 1 and the water chamber heater 2 more securely fixed, and the extended screw 4 makes the water chamber heater 2 and the control chamber 3 more securely fixed.
[0033] Furthermore, a front water chamber sealing ring is provided at the connection between the front water chamber 1 and the water chamber heater 2.
[0034] Furthermore, a sealing ring is provided at the connection between the water chamber heater 2 and the control chamber 3.
[0035] In this embodiment, the front water chamber sealing ring increases the sealing performance between the front water chamber 1 and the water chamber heater 2; the sealing ring also increases the sealing performance between the water chamber heater 2 and the control chamber 3.
[0036] For further details, please refer to Figure 3 The inner water chamber profile 8 and the PTC heating element 7 are fixedly connected by countersunk screws 6.
[0037] In this embodiment, the water chamber heater 2 is provided with an outer water chamber profile 5, multiple inner water chamber profiles 8 and multiple PTC heating elements 7, which are arranged in a layered stacking structure. Finally, countersunk screws 6 are used to fasten and attach the components together. The countersunk screws 6 serve to fix the PTC heating elements 7.
[0038] The working principle and usage process of this utility model: This general-purpose WPTC assembly consists of a front water chamber 1, a water chamber heater 2, and a control chamber 3, which are fastened together by extension screws 4, forming a horizontally integrated sealed WPTC assembly; see reference Figure 3 The water chamber heater 2 is equipped with an outer water chamber profile 5, multiple inner water chamber profiles 8, and multiple PTC heating elements 7, which are arranged in a horizontally stacked structure.
