A kind of plate cooler applied in hydro-generator set

Abstract

The invention discloses a plate cooler applied in a hydroelectric generator set, which comprises a bracket and a fixed plate, an upper beam and a lower beam parallel to the upper beam are arranged between the bracket and the fixed plate, and a sliding device is arranged on the upper beam The sliding block is also provided with a movable plate; a plurality of heat exchange plates are arranged between the movable plate and the fixed plate; a fixed rod for positioning the heat exchange plates is arranged on the fixed plate; the plates include cold water plates and heat exchangers For the water sheet, the heat exchange plate is symmetrically provided with four water outlets and plate grooves for communicating with the water outlets. The two water outlets, the cold water sheet and the hot water sheet are successively arranged at intervals. This solution performs heat exchange between cooling water and high-temperature water through plates, which can not only greatly improve its heat exchange efficiency, but also extend its cooling distance by adding plates, which is highly practical.

Description

technical field [0001] The invention relates to the technical field of cooling devices, in particular to a plate cooler used in a hydroelectric generator set. Background technique [0002] The tubular turbine is mainly suitable for the water head of 1-25m, and it is a special type of the hydropower station with low head and large flow. Since the water flow basically moves along the axial direction in the flow channel without turning, the water passing capacity and hydraulic efficiency of the unit can be improved to some extent. It is especially suitable for tidal power stations, and its functions such as two-way power generation, two-way pumping and two-way water discharge are very suitable for comprehensive utilization of low-head hydraulic resources. As the development of medium and high head hydropower resources has been exhausted, most of the hydropower resources that can be developed are low head. Tubular turbines are suitable for low head applications, and have high e...

Problems solved by technology

[0003] During the existing hydro turbine power generation process, the shaft of the hydro turbine, the governor of the hydro turbine, and especially the generator connected to the hydro turbine will all have severe heat generation, which requires cooling. Most of the current cooling devices use tube cooling. In order to ensure the cooling effect, it is necessary to add an external cooling device to the tube cooler, which not only consumes a lot of energy, but also has a cumbersome structure and affects the use.
