Gasket installed between power packs with cooling water flow path separation

Abstract

The invention relates to a washer which is installed between power groups and has the function of separating the cooling water flow path. It has both the function of separating the cooling water flow path and the function of preventing the cooling water from flowing out. According to the gasket installed between the power packs and having the function of separating the cooling water flow path of the present invention, the upper power pack forming the cooling flow path on the bottom surface and the lower power pack forming the cooling flow path on the upper surface are assembled to share the cooling flow path, And the gasket is connected between the upper power supply pack and the lower power supply pack, and the gasket is formed with an outer airtight wall protruding from the bottom surface of the upper power supply pack along the periphery , and an inner guide wall protruding in close contact with the bottom surface of the upper power pack is formed in a predetermined length section inside the gasket, and a flow control protrusion formed by protruding from the gasket is formed in order to vortex the flowing cooling water.

Description

technical field [0001] The present invention relates to a vehicle gasket suitable for environment-friendly automobiles, and more particularly to a gasket with a cooling water flow path separation function installed between power packs which has both the function of separating the cooling water flow path and the function of preventing the cooling water from flowing out . Background technique [0002] Eco-friendly vehicles such as hybrid vehicles, electric vehicles, etc. generate power through a drive motor, which includes the drive motor, an inverter for supplying power to the drive motor, a low DC-DC converter (Low DC / DC Converter: LDC), high voltage battery and other power packs. [0003] Such a power pack has heat generating elements such as various switching elements, transformers, and insulated gate bipolar transistors (Insulated Gate Bipolar Mode Transistor: IGBT), and therefore requires a cooling device for cooling heat generated during startup.

Problems solved by technology

[0007] However, according to the airtight structure of the cooling flow path of the eco-friendly car of the prior art as described above, the airtightness is performed by the sealant 140 which requires a long hardening time after the joint surface is coated, so the work speed is slow and the airtightness is poor. When removing the sealant 140, it is difficult to remove the sealant 140. During the process of removing the sealant 140, it is easy to damage the LDC 10 or the inverter 20, and the damaged LDC 10 and inverter 20 must be discarded.

[0008] In addition, it is necessary to install another flow path separation plate 130 at a predetermined position between the LDC 10 and the inverter 20. The above-mentioned work is to be performed independently of the airtight work using the sealant 140, so it is necessary to additionally install the flow path separation plate 130. work, reducing work efficiency
