A cooling system for water-cooled engine water tank and its control method

Abstract

The invention relates to a cooling system and a control method thereof for a water-cooled engine water tank for solving the two problems that the area of an existing heat sink is too large and the cooling efficiency of the heat sink cannot be improved simultaneously with the rising of the water temperature due to the fact that the cooling amount for water of the heat sink is unchangeable and belongs to the field of machinery. The cooling system for the water-cooled engine water tank comprises a water sleeve, a cooling unit, a hot water pipe connecting a hot water outlet of the water sleeve and a hot water inlet of the cooling unit, a cold water pipe connecting a cold water inlet of the water sleeve and a cold water outlet of the cooling unit, and two pumps respectively arranged in the hot water pipe and the cold water pipe. The cooling unit is used for replacing the existing heat sink and can reasonably use space and take up little space due to the fact that the cooling unit is in distributed arrangement. The cooling system for the water-cooled engine water tank can be in different cooling power according to different water temperature and adjustable in the cooling amount for water, thereby improving the cooling efficiency with the rising of the water temperature.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a cooling system for a water tank of a water-cooled engine and a control method thereof. Background technique [0002] The water tank is an important part of the water-cooled engine. As an important component of the cooling circuit of the water-cooled engine, it can absorb the heat of the cylinder block. The heat of the engine passes through the liquid circuit of cooling water, uses water as a heat carrier to conduct heat, and then passes through Large-area radiators dissipate heat by convection to maintain the proper operating temperature of the engine. Because the area of ​​the heat sink is too large, it takes up a lot of space; the area of ​​the heat sink is fixed, so the cooling capacity of the water is also fixed, and the cooling efficiency will not be improved synchronously with the increase of the water temperature. As the temperature rises, the temperature of the ret...
