Abstract

A large-size liquid-cooling cooler for an electric vehicle includes a liquid-cooling cooler body and at least one bonding interface layer. The liquid-cooling cooler body has a projection area greater than 150 cm 2 , and a cooling flow channel is formed inside the liquid-cooling cooler body for allowing cooling fluid to flow through the cooling flow channel. The at least one bonding interface layer is a cold spray coating layer formed on the liquid-cooling cooler body by cold spraying and corresponds in position to the cooling flow channel. A projection area of the at least one bonding interface layer is greater than 30 cm 2 , a thickness of the at least one bonding interface layer is between 0.03 mm and 0.25 mm, and a ten-point average roughness (Rz) of a surface of the at least one bonding interface layer is from 30 μm to 90 μm.

First claim

What is claimed is:

1 . A large-size liquid-cooling cooler for an electric vehicle, configured to be bonded to at least one electric vehicle power module, comprising:
a liquid-cooling cooler body having a projection area greater than 150 cm 2 , wherein a cooling flow channel is formed inside the liquid-cooling cooler body for allowing cooling fluid to flow through the cooling flow channel; and at least one bonding interface layer being a cold spray coating layer formed on the liquid-cooling cooler body by cold spraying and corresponding in position to the cooling flow channel; wherein a projection area of the at least one bonding interface layer is greater than 30 cm 2 , a thickness of the at least one bonding interface layer is between 0.03 mm and 0.25 mm, and a ten-point average roughness (Rz) of a surface of the at least one bonding interface layer is from 30 μm to 90 μm.

2 . The large-size liquid-cooling cooler according to claim 1 , wherein the liquid-cooling cooler body has a first surface and a second surface that are opposite to each other, and the liquid-cooling cooler body includes a first cooler member and a second cooler member; wherein an outer surface of the first cooler member is the first surface, and an outer surface of the second cooler member is the second surface; wherein at least one cavity is formed between the first cooler member and the second cooler member, and the at least one cavity is the cooling flow channel.

3 . The large-size liquid-cooling cooler according to claim 2 , wherein the first cooler member is a plate, and a plate thickness of the first cooler member is from 0.5 mm to 3 mm.

4 . The large-size liquid-cooling cooler according to claim 1 , wherein the liquid-cooling cooler body is made of aluminum or aluminum alloy.

5 . The large-size liquid-cooling cooler according to claim 1 , wherein the cooling flow channel has a bent shape.

6 . The large-size liquid-cooling cooler according to claim 1 , wherein a flow channel height of the cooling flow channel corresponding in position to the at least one bonding interface layer is from 2 mm to 8 mm.

7 . The large-size liquid-cooling cooler according to claim 6 , wherein a body thickness of the liquid-cooling cooler body is 1.2 times to 4 times the flow channel height of the cooling flow channel corresponding in position to the at least one bonding interface layer.

8 . The large-size liquid-cooling cooler according to claim 1 , wherein plurality ones of the bonding interface layers correspond in position to the cooling flow channel, the bonding interface layers are arranged in pairs, and one of the pairs of bonding interface layers correspond in position to another one of the pairs of bonding interface layers.
