On the premise that the interior space of the automobile allows, fans may be further provided in the circumferential direction of the heat radiating core 2, and the number of fans may be plural. It is worth noting that the position where the fan is arranged is specifically arranged between the automobile heating component and the radiator, the fan can generate air flow when the power is on, and air outside the heating component is blown to the position where the radiator is located, so that the heat dissipation rate of the outer surface of the heating component is improved.

Referring to fig. 2 and 3, the present embodiment provides a split-type intake chamber 1, which includes an intake chamber body 11, a water inlet 12 and a first split-flow plate 14, wherein the intake chamber body 11 includes a first chamber 13; the water inlet 12 is arranged on the water inlet chamber body 11, and the cooling liquid enters the first chamber 13 through the water inlet 12; the first flow dividing plate 14 is disposed in the first chamber 13, one end of the first flow dividing plate 14 is connected with the water inlet 12, and the other end of the first flow dividing plate 14 extends along the direction from the water inlet 12 to the heat dissipation core 2.

For convenience of explanation, arrows in the drawings indicate the flow direction of the coolant, which will be described later.

The external dimension of the intake chamber body 11 is the same as that of the intake chamber 1 of the existing automobile radiator, so that the existing automobile radiator can be conveniently adapted. The first chamber 13 is arranged inside the water inlet chamber body 11, the first chamber 13 is also communicated with the heat dissipation core 2, and cooling liquid enters the first chamber 13 through the water inlet 12 and flows into the heat dissipation core 2 through the first chamber 13. The number of the heat dissipation cores 2 is plural, and then the edge of the first chamber 13 is distributed with a plurality of outlets which are communicated with the hollow pipeline of the heat dissipation cores 2, when the cooling liquid flows into the first chamber 13, if the cooling liquid is unevenly distributed in the first chamber 13, the cooling liquid can preferentially flow into the heat dissipation cores 2 near the water inlet 12, so that no cooling liquid flows in the heat dissipation cores 2 far away from the water inlet 12.

The first flow dividing plates 14 are distributed at the water inlet 12, and the other ends of the first flow dividing plates 14 extend in the direction from the water inlet 12 to the heat dissipation core 2, which can be understood here as: when there are a plurality of heat dissipation cores 2, the number of the first flow dividing plates 14 is also a plurality of, one end of each of the plurality of first flow dividing plates 14 is connected with the water inlet 12, and the other end of each of the plurality of first flow dividing plates 14 extends to the position where the plurality of heat dissipation cores 2 are located, and it is worth noting that the intervals between the extending ends of two adjacent first flow dividing plates 14 are not too different, so that the cooling liquid entering the first chamber 13 from the water inlet 12 can be uniformly dispersed into the plurality of heat dissipation cores 2.

In the present embodiment, a plurality of first flow dividing plates 14 may be disposed in the first chamber 13, and it is noted that the number of the plurality of first flow dividing plates 14 may not be in one-to-one correspondence with the number of the heat dissipation cores 2, for example, when there are 20 heat dissipation cores 2, the number of the first flow dividing plates 14 is not necessarily 20, but may be 10, 15, or the like; of course, the number of the first flow dividing plates 14 may be the same as the number of the heat dissipation cores 2.

In this embodiment, the interval between two adjacent first flow dividing plates 14 gradually increases along the direction from the water inlet 12 to the heat dissipation core 2, as can be further understood with reference to fig. 3: when a plurality of first splitter plates 14 are provided, two adjacent first splitter plates 14 are not parallel, but are disposed at an included angle. The space between the two first flow dividing plates 14 is larger on the side closer to the heat dissipation core 2, whereas the space between the two first flow dividing plates 14 is smaller on the side closer to the water inlet 12, so that when the cooling liquid enters the first chamber 13 at the water inlet 12, the cooling liquid is divided into multiple parts by the first flow dividing plates 14, and the single part of the cooling liquid gradually diffuses towards the direction of the heat dissipation core 2 in the space of the two adjacent first flow dividing plates 14 and then enters the hollow pipeline of the heat dissipation core 2, thereby avoiding excessive concentration of the cooling liquid at the position, close to the water inlet 12, in the first chamber 13, and improving the dispersion uniformity of the cooling liquid in the first chamber 13.

The third flow dividing plate 16 is provided with a plurality of flow dividing holes, the plurality of flow dividing holes can be arrayed on the third flow dividing plate 16, when the cooling liquid is drained to the third flow dividing plate 16, the cooling liquid enters the heat dissipation core body 2 from the flow dividing holes, and the plurality of flow dividing holes can promote the uniform dispersion degree of the cooling liquid in the first flow dividing plate 14.

As an alternative embodiment, the number of third flow dividing plates 16 may be plural, and the arrays may be distributed on one first flow dividing plate 14, so that the coolant may be distributed more uniformly in the space separated by two adjacent first flow dividing plates 14, thereby improving the uniformity of the coolant distribution at the ends of the plurality of heat dissipation cores 2.

In this embodiment, the end of the first diverter plate 14 is the end of the first diverter plate 14 near the water inlet 12, and is connected to the diverter bottom plate 17. The distance between the split bottom plate 17 and the inner wall of the first chamber 13 gradually decreases along the direction from the water inlet 12 to the heat dissipation core 2 according to a preset gradient, which can be understood as follows: the split bottom plate 17 is obliquely arranged on the inner wall of the first chamber 13, the preset gradient can be understood as a distance change value between the split bottom plate 17 and the inner wall of the first chamber 13, the preset gradient can be preset, and the smaller the distance between the split bottom plate 17 and the first chamber 13 is near one side of the heat dissipation core 2, namely, the inclined direction of the split bottom plate 17 is the direction towards one side of the heat dissipation core 2, when the cooling liquid enters the first chamber 13 at the water inlet 12, the split bottom plate 17 converts the flow direction of the cooling liquid into the direction towards the heat dissipation core 2, so that the flow direction in the cooling liquid is consistent, and the problems of vortex, whirl and the like are avoided.
