Embodiment 1

[0022] Such as figure 1 As shown, the multi-temperature zone integrated radiator of the present invention includes a high-temperature heat dissipation module and a low-temperature heat dissipation module, a water inlet chamber 1, a high-temperature water inlet 2, a left main piece 3, a low-temperature water inlet 4, a high-temperature core body 5, a partition Plate 6, low temperature core body 7, water outlet chamber 8, high temperature water outlet 9, right main piece 10 and low temperature water outlet 11. The specific structure and connection relationship are:

[0023] The high temperature heat dissipation module is composed of water inlet chamber 1, high temperature water inlet 2, left main piece 3, high temperature core body 5, water outlet chamber 8, high temperature water outlet 9 and right main piece 10; the low temperature heat dissipation module is composed of water inlet chamber 1, The low temperature water inlet 4, the left main piece 3, the low temperature core b...

Embodiment 2

[0027] This embodiment is an example of a one-piece radiator partition.

[0028] Such as figure 2 As shown, the separator of the multi-temperature zone integrated radiator of the present invention. The water inlet chamber 1 is divided into two parts, the high temperature zone 12 of the water inlet chamber and the low temperature zone 17 of the water inlet chamber, by the partition plate 15 of the water chamber. The water chamber partition 15 ensures that the cooling liquids in the high and low temperature heat dissipation modules do not mix. There is a partition 6 between the high-temperature cooling pipe 14 on one side of the high-temperature heat dissipation module and the low-temperature cooling pipe 18 on one side of the low-temperature heat dissipation module. There is a heat dissipation belt 13 between the high-temperature cooling pipe 14 , the low-temperature cooling pipe 18 and the partition plate 6 . The dividing plate 6 increases the distance between the high-tem...

Embodiment 3

[0030] This embodiment is an example of the way of connecting the separator and the main sheet.

[0031] Such as image 3 As shown, the connection between the partition 6 and the left main piece 3 is plug-in, that is, the head of the partition 6 passes through the left main piece 3 and is connected into one body by brazing.

[0032] Such as Figure 4 As shown, the connection mode of the partition 6 and the left main sheet 3 is an overlapping type, that is, the end of the partition 6 is in contact with the surface of the left main sheet 3 . The two are joined together by brazing.

Abstract

The invention provides a multi-temperature zone integrated heat sink. The multi-temperature zone integrated heat sink is formed by combination of a high-temperature heat dissipation module and a low-temperature heat dissipation module, wherein both the high-temperature heat dissipation module and the low-temperature heat dissipation module are formed by combination of water chambers and core bodies in a crimping manner; a cooling pipe, a heat dissipation belt, a main leaf and a baffle plate are brazed to form the integrated core body; the high-temperature heat dissipation module and the low-temperature heat dissipation module share the main leaf and the water chamber; the water chambers of the high-temperature heat dissipation module and the low-temperature heat dissipation module are separated by a water chamber baffle plate so as to prevent high temperature cooling liquid and low temperature cooling liquid from being mixed with each other; and the core bodies of the high-temperature heat dissipation module and the low-temperature heat dissipation module are separated by a baffle plate so as to reduce thermal stress generated due to temperature difference between the high-temperature heat dissipation module and the low-temperature heat dissipation module and prolong the service life.

Description

technical field [0001] The invention relates to the field of radiators for passenger cars, commercial vehicles, construction machinery, etc., in particular to a multi-temperature zone integrated radiator. Background technique [0002] As the country's requirements for vehicle emission standards become more and more stringent, in order to meet the emission standards, people design more and more complex vehicles, whether it is traditional power, hybrid or pure electric vehicles. The same is true for the design of the radiator, which is the main accessory of the engine cooling system. The cooling system often has multiple radiators to achieve different heat dissipation functions. Some radiators are assembled in a single body, which has a complex structure, large volume, and takes up a lot of space; some radiators are integrated into one body to make Multi-temperature zone radiator can save installation space. The existing multi-temperature zone radiators for vehicles simply c...
