1. A heat exchanger, comprising:
a tube panel module elongated in a vertical direction and including a plurality of first tube panels and a plurality of second tube panels that are alternately arranged in a lateral direction;
header panel modules respectively formed at an upper end and a lower end of the tube panel module and elongated in the lateral direction; and
a header case having an open one side, providing a space therein, and covered on the one side by one of the header panel modules such that the plurality of first tube panels and the plurality of second tube panels communicate with the space, wherein each first tube panel is formed by bonding a first panel and a second panel, each second tube panel is formed by bonding a third panel and a fourth panel, and each header panel module includes:
a first header panel formed by bending both ends of the first panel and the second panel in opposite directions; and
a second header panel formed by bending both ends of the third panel and the fourth panel in opposite directions and bonded to the first header panel between every first tube panel and second tube panel, wherein when portions positioned at a first lateral end and a second lateral end of the header panel module and protruding laterally from the tube panel module are defined as insertion panels, the header case further includes first insertion grooves that are recessed on a first lateral side and a second lateral side of the header case to face the space and in which the insertion panels are inserted.
