The second bottom wall 22 is long, the outer contour of the second bottom wall 22 is smaller than that of the first bottom wall 11, and the second peripheral wall 23 is vertically arranged at the edge of the second bottom wall 22. When the cover 2 is connected to the main body 1, the first peripheral wall 12 is connected to the second peripheral wall 23 so that the cover 2 can be connected to the main body 1.

Referring to fig. 11, the projection 21 includes a first vertical surface 212 and an inclined surface 213, the first vertical surface 212 being coplanar with the inner surface of the second peripheral wall 23. The first vertical surface 212 and the inclined surface 213 form an included angle E in the range of 15 ° to 45 °. When the included angle E is smaller than 15 °, the maximum distance from the first vertical surface 212 to the inclined surface 213 is too narrow, the structural strength of the protruding portion 21 is too low, and the protruding portion 21 is easy to bend, so that the protruding portion 21 cannot support the first wall 131, and the structural strength between the first wall 131 and the first bottom wall 11 cannot be improved. When the included angle E is greater than 45 °, the maximum distance from the first vertical surface 212 to the inclined surface 213 is too wide, and the protruding portion 21 occupies the space of the limiting receiving cavity 102, which is not beneficial for assembling and positioning the sealing element 3 in the limiting receiving cavity 102. In the embodiment of the present application, the apex angle of the angle E is arc-shaped to improve the structural strength at the junction of the first vertical surface 212 and the inclined surface 213. In other embodiments, if the protruding portion 21 is made of a material with high strength, the protruding portion 21 may have a rectangular structure, that is, the first vertical surface 212 and the inclined surface 213 are parallel to each other.

Referring to fig. 10 to 11, the protruding portion 21 further has an abutment surface 211, and the abutment surface 211 is located on a side of the inclined surface 213 away from the first vertical surface 212. The preferred first vertical surface 212, inclined surface 213 and abutment surface 211 form a right triangle configuration. The projection 21 also has a second vertical surface 215, the second vertical surface 215 being located on the side of the abutment surface 211 remote from the first vertical surface 212. Specifically, the second vertical surface 212 is coplanar with the outer surface of the second peripheral wall 23, the first vertical surface 212 is parallel to the second vertical surface 215, and the inclined surface 213 is perpendicular to the second vertical surface 215. When the protruding portion 21 extends into the limiting accommodating cavity 102, the inclined surface 213 and the abutting surface 211 are respectively in sealing connection with the sealing member 3, so as to improve the sealing performance between the cover body 2 and the main body 1. An arc surface 214 is arranged between the abutting surface 211 and the inclined surface 213, the arc surface 214 is matched with the outer wall of the sealing element 3, and the overall structural strength between the abutting surface 211 and the inclined surface 213 is enhanced by arranging the arc surface 214, so that the risk of fracture between the abutting surface 211 and the inclined surface 213 is reduced. At the same time, the outer wall of the sealing member 3 can be in sealing connection with the inclined surface 213 and the abutting surface 211, so that the sealing performance is improved.

Referring to fig. 7 and 11, the maximum distance from the first vertical surface 212 to the inclined surface 213 is 1/5 to 1/2 of the distance from the first vertical surface 212 to the second vertical surface 215. Definition: the maximum distance from the first vertical surface 212 to the inclined surface 213 is a first distance W1; the distance from the first vertical surface 212 to the second vertical surface 215 is the second distance W2, i.e., the length of the first distance W1 is 1/5 to 1/2 of the length of the second distance W2. When the length of the first distance W1 is less than 1/5 of the length of the second distance W2, the first distance W1 is too short, the thickness of the protrusion 21 is too thin, and the protrusion 21 cannot provide a supporting force to the first wall 131, so that the structural strength of the junction of the first wall 131 and the first bottom wall 11 cannot be reinforced. When the length of the first distance W1 is greater than 1/2 of the length of the second distance W2, the thickness of the protruding portion 21 is too thick, and the protruding portion 21 occupies the space of the limiting accommodating cavity 102, so that the assembly of the sealing element 3 is affected. In an embodiment of the application, the length of the first distance W1 does not exceed 1/2 of the length of the second distance W2. Preferably, the distance from the first vertical surface 212 to the inclined surface 213 is not less than 1mm, that is, the length of the first distance W1 is not less than 1mm, so that the structural strength of the protruding portion 21 is enhanced, and the filling rate of the sealing member 3 in the limiting accommodating cavity 102 is satisfied.

Referring to fig. 7, the height of the protrusion 21 is 1/2 to 3/4 of the distance from the inner wall surface 103 of the second wall 132 to the contact surface 211. Definition: the height of the protruding portion 21 is a first height H1, and the first height H1 is a vertical distance from the apex angle of the first vertical surface 212 and the inclined surface 213 to the contact surface 211. Definition: the distance from the inner wall surface 103 of the second wall 132 to the abutment surface 211 is a third distance H2. That is, the first height H1 is 1/2 to 3/4 of the third distance H2. When the first height H1 is greater than 3/4 of the third distance H2, the top of the angle E is easily contacted with the junction of the first wall 131 and the second wall 132 during assembly, thereby generating stress concentration, so that the junction of the first wall 131 and the second wall 132 is easily broken. When the first height H1 is smaller than 1/2 of the third distance H2, the contact area between the first vertical surface 212 and the inner wall surface 103 of the first wall 131 becomes smaller, and the supporting force provided to the first wall 131 is reduced, so that the structural strength between the first wall 131 and the first bottom wall 11 is also reduced, and liquid leakage is likely to occur.

Referring to fig. 1 to 2, the present application further discloses a heat exchanger 200, which includes a water chamber device 100, and the heat exchanger 200 further includes a plurality of flat tubes 210, wherein each flat tube 210 includes two opposite connection ends 220 and a channel between the two connection ends 220.
