Description

Technical Field

[0001] This utility model is a dual-NTC structure water PTC heater for new energy vehicles, belonging to the technical field of water PTC heaters. Background Technology

[0002] Existing PTC water heating elements consist of a metal casing housing a PTC heating unit, which is connected to an external power source via a power cord. When needed, the PTC water heating element is placed in the water to be heated, and then the water is heated by the power supply.

[0003] However, when assembling existing water PTC heaters with vehicles, the inlet and outlet ports 1 and 2 of the water PTC heaters need to be matched with the inlets and outlets on the vehicle, which results in installation errors due to mismatch, high manual intervention, and reduced production efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dual-NTC structure water PTC heater for new energy vehicles.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A dual-NTC structure PTC water heater for new energy vehicles includes an aluminum water channel component, an aluminum water tank at the bottom of the aluminum water channel component, a PTC compartment sealing cover at the top of the aluminum water channel component, and a controller compartment sealing cover on one side of the aluminum water channel component and the aluminum water tank.

[0007] A high-voltage socket and a low-voltage socket are respectively provided on one side of the controller compartment sealing cover and above the PTC compartment sealing cover;

[0008] The aluminum water channel component is provided with an inlet and an outlet 1 and an inlet and an outlet 2 on one side, respectively. NTC temperature sensors are symmetrically arranged inside the aluminum water channel component and located at the inlet and outlet 1 and the inlet and outlet 2.

[0009] Preferably, a sealing ring is provided between the aluminum water channel component and the aluminum water tank, and they are connected by bolts.

[0010] Preferably, the controller compartment is equipped with a controller inside the sealed cover, and the controller is provided with a plastic insulating component.

[0011] Preferably, the aluminum water channel component is provided with a PTC heating element, and the top of the PTC heating element is connected to a manifold.

[0012] The beneficial effects of this utility model are:

[0013] By symmetrically installing two NTC temperature sensors at the inlet and outlet ports 1 and 2 on the aluminum water channel component, an indiscriminate use method for the inlet and outlet can be achieved, so that the interchangeable installation of the inlet and outlet on the vehicle does not affect temperature acquisition and control.
