    • An exhaust gas heat exchanger for a cogeneration system is disclosed. In the exhaust gas heat exchanger, a heat exchanger cover is arranged around a heat exchanger body such that a primary heat medium passage, through which a heat medium passes, is defined between the heat exchanger cover and the heat exchanger body. In the heat exchanger body, a heat medium tube forming a secondary heat medium passage, through which the heat medium emerging from the primary heat medium passage passes, is arranged. Accordingly, the heat medium primarily absorbs heat from the exhaust gas while passing through the primary heat medium passage, and then secondarily absorbs heat from the exhaust gas while passing through the secondary heat medium passage. As a result, an enhancement in heat exchanging efficiency is achieved.
    • 公开了一种用于热电联产系统的排气热交换器。 在排气热交换器中,在热交换器主体的周围配置热交换器盖,在热交换器盖和热交换器主体之间限定有热介质通过的一次以上的热介质通路。 在热交换器主体中,设置形成从一次热介质通道出来的热介质通过的二次热介质通路的热介质管。 因此,热介质在通过一次导热介质通路的同时主要从排气中吸收热量,然后在通过二次热介质通路的同时二次从排气中吸收热量。 结果,实现了热交换效率的提高。
