[0090] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0091] According to the first aspect of the present application, with reference to Figures 1 to 9 , the present disclosure provides a radiator 100, including: a heat dissipation core 110 and a first end cap 120.

[0092] The heat dissipation core 110 has a working medium channel for the cooling working medium to flow through, and is used to cool the passing cooling working medium; the first end cap 120 is used to form a connection between the heat dissipation core 110 and an external device, realize the exchange of the cooling working medium with the external device or serve as an intermediary between different external devices. Exemplarily, the external devices include a water pump, a heating system, a plate heat exchanger, a PTC (Positive Temperature Coefficient) water heater, a power assembly, etc.

[0093] The first end cap 120 includes: an end cap main body 121, a valve body 122 and an external connection interface 123.

[0094] The end cap main body 121 is fixedly connected to one end of the heat dissipation core 110. The valve body 122 is installed on the end cap main body 121, and has a valve inner space 122a for accommodating a valve core 131. The valve inner space 122a is communicated with the working medium channel. The external connection interface 123 is formed with a valve flow path 123a, and the valve flow path 123a is communicated with the valve inner space 122a. The external connection interface 123 is used to connect an external device to form a circulation loop.

[0095] Through the above technical solution, the first end cap 120 of the radiator 100 is formed by the end cap main body 121 and the valve body 122, and the valve core 131 can be installed in the valve inner space 122a of the valve body 122, so that the radiator 100 of the present application integrates the functions of heat dissipation and valve body, has a compact structure, reduces the number of mounting brackets and connecting pipelines, thereby reducing the required assembly links and improving the assembly efficiency.

[0096] Meanwhile, the valve body 122 is integrated into the radiator 100, eliminating the pipelines, seals 171, fixing parts, etc. required between the water valve and the radiator 100 in the prior art, making the entire assembly more concise, facilitating installation, greatly reducing the production manufacturing process and costs, improving reliability, playing a huge role in the space utilization and cost control of the whole vehicle, and providing a product with a more compact structure and higher layout convenience for the trend of component integration.

[0097] In some embodiments, referring to Figure 1 and Figure 3 , the head body 121 is located between the valve body 122 and the heat dissipation core 110.

[0098] It can be understood that both the head body 121 and the valve body 122 are located on the heat dissipation plane of the heat dissipation core 110, which can avoid the superposition of the valve body 122 and the head body 121 in the direction perpendicular to the heat dissipation plane, and reduce the size of the overall head body 121, valve body 122 and heat dissipation core 110 in the direction perpendicular to the heat dissipation plane.
