[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See Figs. 1 to 3 As shown, an evaporator assembly involved in this embodiment includes an aluminum plate 100 and an aluminum coil 200. One end face of the aluminum plate 100 is pressed with a plurality of semi-circular grooves 101 arranged at intervals along the length direction and extending in a straight line along the width direction. Both ends of the semi-circular grooves 101 are connected to the outside. The aluminum coil 200 is in the shape of a circular tube and includes a plurality of straight tube sections 201 arranged in parallel. A transition bend 202 is connected in series between two adjacent straight tube sections 201. The aluminum coil 200 also includes an inlet section 203 and an outlet section 204 provided at the end. The straight tube sections 201 are adapted to be installed in the semi-circular grooves 101. The aluminum plate 100 is provided with a square-shaped anti-interference hole 102 for the transition bend to be inserted.

[0018] Furthermore, both the inlet portion 203 and the outlet portion 204 extend out of one end of the semi-circular groove 101.

[0019] Furthermore, the distance between two adjacent semicircular grooves 101 is equal; the distance between two adjacent straight pipe sections 201 is equal; and the distance between two adjacent semicircular grooves 101 is equal to the distance between two adjacent straight pipe sections 201.

[0020] Furthermore, the outer wall of the straight tube 201 is tightly attached to the inner wall of the semi-circular groove 101.

[0021] In this embodiment, by pressing the thin aluminum plate 100, a semi-circular groove 101 is formed for the straight tube section 201 to accommodate the mounting, and an anti-interference hole 102 is formed for the transition bend 202 to avoid interference. This ensures that the forming is not damaged, while greatly increasing the contact area between the aluminum plate 100 and the aluminum coil 200.

[0022] The evaporator assembly involved in this utility model significantly increases the contact area between the aluminum plate and the aluminum coil while ensuring that the processing technology is not complicated, thereby accelerating the heat transfer speed, improving the overall function, and making it highly practical.
