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. 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] In high-voltage environments, the WPTC assembly of new energy vehicles uses a liquid heating device to heat the driver's cabin and battery pack. Due to the significant differences in market requirements for WPTC assemblies, there are mainly three 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 to solve the above problems. Utility Model Content

[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.

The three inner water chamber profiles 6 are evenly spaced along the vertical direction. A PTC heating pack 7 is provided between every two inner water chamber profiles 6, so that the coolant can transfer the heat of the PTC heating pack 7 when passing through the inner water chamber profile 6.

[0029] This utility model, through its vertically stacked structure design of heating pack and aluminum profile water chamber, can achieve full coverage of product voltage from 0V to 800V, while the length of the aluminum profile water chamber produced by extrusion process can be adjusted at will, achieving full coverage of product power from 1KW to 18KW.
