Description

Technical Field

[0001] This utility model relates to the field of thermal management system technology, and more specifically, to a Chiller connection structure for a thermal management integrated module. Background Technology

[0002] The chiller is one of the most important components in the thermal management integrated module system of new energy vehicles. It mainly integrates the cooling circuit side and the water circuit side to cool the power battery. The stability of its performance directly affects the service life of the power battery. The chiller is connected to the vehicle body or the thermal management integrated module by a bracket welded to the chiller. During the product welding process, the bracket is prone to deformation or poor welding during high-temperature welding. At present, the bracket structure of the chiller in new energy vehicles is only used for fixing the chiller itself and cannot connect other components, resulting in low utilization of internal space.

[0003] The applicant discovered through a search that Chinese patent document with publication number 216843788U, published on June 28, 2022, discloses a detachable base for a water-cooled chiller, including a mounting base. The mounting base has a limit plate, a support, and a first spring seat on its lower side. The limit plate has a limit groove. The support has brackets on both the front and rear sides of its lower end face. The adjacent end faces of the brackets on both the front and rear sides have longitudinally arranged rotating arms. The upper end of the rotating arm passes through the mounting base and has a limit hook. This device also cannot solve the above-mentioned technical problem.

[0004] Therefore, in order to improve or solve at least one of the above problems, it is necessary to provide a thermal management integrated module Chiller connection structure that can provide mounting positions for multiple components. Utility Model Content
