Abstract:
1. A power battery pack cooling apparatus, comprising: a cooling grid array comprising a plurality of cooling duct plates having divided hollow flow ducts for coolant to pass through, wherein the plurality of cooling duct plates have two ends, and two cooling duct end plates having cut-out slots, wherein the two ends of the plurality of cooling duct plates are respectively coupled with the two cooling duct end plates through the cut-out slots, forming a leak-proof joint; a front cover having a coolant inlet and outlet that enable the coolant to flow into and out of the cooling apparatus, wherein the front cover is provided with an attached front rubber sheet with a front cut-outs pattern having a plurality of front cut-outs, wherein the front rubber sheet is attached onto one of the two cooling duct end plates, thereby a plurality of enclosed front cut-out spaces are formed by the plurality of the front cut-outs between the front cover and the cooling duct end plate; and a back cover with an attached back rubber sheet with a back cut-outs pattern having a plurality of back cut-outs, wherein the back cut-outs pattern is different from the front cut-outs pattern, and wherein the back rubber sheet is attached onto the other of the two cooling duct end plates, thereby a plurality of enclosed back cut-out spaces are formed by the plurality of the back cut-outs between the back cover and the cooling duct end plate; whereby the enclosed front and back cut-out spaces are so arranged in their relative positions to the divided hollow flow ducts so as to facilitate the flow and direction change of the coolant in the divided hollow flow ducts.
