Title:
HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2018132227
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat exchanger enabling downsizing and weight saving thanks to improvement of heat exchange efficiency compared to conventional one, and capable of improving pressure resistance of a shell, preventing clogging at low pressure loss, and improving productivity.SOLUTION: An object is to provide a heat exchanger that includes a fin-and-tube type heat exchange unit having a large inner and outer area ratio and a plate configured to prevent internal bypass, to improve heat efficiency and attain downsizing and weight saving; employs a cylinder as a shell, to improve pressure resistance; and makes a fin pitch wide, to prevent clogging at low pressure loss. Also, a shielding plate and a buffle plate included therein do not need welding, and the shell employs a seamless tube, so that the number of welding places can be greatly reduced to improve productivity.SELECTED DRAWING: Figure 1
