Title:
HEAT-EXCHANGING DEVICE FOR SINGLE CHANNEL HEAT TREATMENT FURNACE
Document Type and Number:
WIPO Patent Application WO/2017/000093
Kind Code:
A1
Abstract:
A heat-exchanging device for a single channel heat treatment furnace comprises: a furnace body comprising a front heat-exchanging region (102), a heating and heat-retaining region (105), a process temperature region (106, 107) and a rear heat-exchanging region (108). An insulating door (104) is disposed between the front heat-exchanging region (102) and the rear heat-exchanging region (108). Circulating heat-exchanging air flow paths (112, 113) are disposed between the front heat-exchanging region (102) and the rear heat-exchanging region (108). The heat-exchanging device of the single channel heat treatment furnace causes a heat-treated part to enter the rear heat-exchanging region (108), and then a heat-exchanging fan (101) transfers a furnace gas to the rear heat-exchanging region (108), so that heat dissipated from the part in the rear heat-exchanging region (108) is continuously brought to the front heat-exchanging region (102) to heat a cold workpiece newly entering the front heat-exchanging region (108), thereby effectuating a heat exchange between cold and hot parts in the front and rear regions to cool down the hot part and heat up the cold part. Therefore, residual heat is efficiently utilized to achieve a high efficiency and an energy saving effect.
