Problems solved by technology

[0015] However, the combined heat and power system in the prior art has such a shortcoming: when the engine room (E) is at a high temperature due to the heat energy emitted by the engine 4 itself, the temperature inside the control box 22 is easily increased, causing the control box 22 to Abnormal operation of the internal printed circuit board (PCB), resulting in reduced reliability of the system, because the engine 4, generator 2 and control box 22 are installed in one engine room (E) formed by the chassis

Abstract

Provided is a cogeneration system. The system includes a chassis, a controller cooling unit, and a driver cooling unit. The chassis is provided with a generator, a driving source, a waste heat recovering unit, and a controller. The generator generates power. The driving source drives the generator and generates heat. The waste heat recovering unit recovers a waste heat of the driving source. The controller controls operations of the generator, the driving source, and the waste heat recovering unit. The controller cooling unit introduces air at one side inside the chassis, circulates the introduced air, and cools at least any one of the generator and the controller. The driver cooling unit introduces air at the other side inside the chassis, circulates the introduced air, and cools at least any one of the driving source and the waste heat recovering unit.

Description

technical field [0001] The present invention relates to a combined heat and power system, and more particularly, to a combined heat and power system for preventing a controller from being overheated by thermal energy generated in an engine, thereby improving reliability and efficiency. Background technique [0002] In general, a combined heat and power system refers to a system that simultaneously generates electricity and heat from a single energy source. [0003] FIG. 1 is a schematic diagram of a cogeneration system in the prior art. [0004] As shown in Figure 1, the cogeneration system in the prior art includes: a generator 2 for generating electric energy; a driving source (hereinafter referred to as "engine"), such as an engine 4, for driving the generator 2, and generating thermal energy; a waste heat recovery unit for recovering waste heat generated in the engine 4; a heat destination unit (heat destination) 10, such as a heat energy storage tank, utilizing the was...
