Specifically, the second bottom wall 11 is elongated, and the second peripheral wall 12 extends to one side of the lid body 2 away from the edge of the second bottom wall 11. Preferably, the second bottom wall 11 is perpendicular to the second peripheral wall 12. The first bottom wall 21 is elongated so that the cover 2 can cover the main body 1. The main body 1 further comprises a limiting accommodating portion 13, the limiting accommodating portion 13 is arranged between the second bottom wall 11 and the second peripheral wall 12, one end of the limiting accommodating portion 13 is connected with the edge of the second bottom wall 11, the other end of the limiting accommodating portion 13 is connected with one side edge of the second peripheral wall 12, and the limiting accommodating portion 13 is provided with a limiting accommodating cavity 103.

Referring to fig. 8 and 11 to 13, the boss portion 32 of the sealing member 3 protrudes from the body 31, and the protruding height of the boss portion 32 is not lower than the depth of the limit groove 201. If the height of the boss 32 is smaller than the depth of the limit groove 201, the body 42 is easily extruded into the limit groove 201 during assembly, thereby affecting the filling rate of the body 31 in the limit accommodating cavity 103, resulting in a decrease in sealing performance between the body 31 and the limit accommodating portion 13, and thus causing leakage. In the embodiment of the present application, the boss portion 32 is integral with the body 31.

The boss portion 32 includes a rib 322, and the rib 322 is at least partially located in the limit slot 201. The convex rib 322 protrudes outwards from the body 31, and the convex rib 322 is in clearance fit with the limit groove 201. Specifically, definition: the height of the rib 322 is a first height H1, and the first height H1 is a distance from the peripheral wall of the body 31 to the free end of the rib 322. The depth of the limiting groove 201 is a first depth H2, and the first depth H2 is a distance from the first opening 2001 to the free end of the first peripheral wall 22. That is, the first height H1 is not lower than the first depth H2. The body 31 is not extruded into the limit groove 201, so that the filling rate of the body 31 in the limit accommodating cavity 103 is not affected, and the sealing performance is improved.

The boss portion 32 includes a plurality of protruding points 321, and a plurality of protruding points 321 evenly distributed are in protruding muscle 322, and a plurality of protruding points 321 and spacing groove 201 interference fit. In the embodiment of the application, the shape of the convex points 321 is rectangular, and the distance between two adjacent convex points 321 is 10 mm-30 mm, so that the sealing element 3 can form continuous sealing with the cover body 2, and the risk of leakage of liquid between the two convex points 321 is reduced. In the embodiment of the present application, the shape of the seal 3 is adapted to the shape of the body 1 and the cover 2. The seal 3 is substantially rectangular. The body 31 includes two opposite long sides 311 and two opposite short sides 312, and the two long sides 311 and the two short sides 312 are connected end to end in sequence to form a rectangle. If the length of the two short sides 312 of the seal is too small, the protruding point 321 may not be provided, and thus the seal between the body 1 and the lid 2 can be satisfied.

Referring to fig. 8 to 10, the first protruding portion 231 includes a first surface 2311 facing the limiting groove 201 and a second surface 2312 disposed opposite to the first surface 2311, and the second protruding portion 232 includes a third surface 2321 facing the limiting groove 201 and a fourth surface 2322 disposed opposite to the first surface 2322. When the cover 2 is fixed to the main body 1, the first protruding portion 231 and the second protruding portion 232 extend into the spacing accommodating cavity 103 at the same time, the second surface 2312 of the first protruding portion 231 is attached to the inner wall surface of the first wall 131, the fourth surface 2322 of the second protruding portion 232 is attached to the inner wall surface of the third wall 133, and the first protruding portion 231 can provide supporting force to the connection portion between the first wall 131 and the second bottom wall 11, so as to strengthen the structural strength of the connection portion between the first wall 131 and the second bottom wall 11. The second protruding portion 232 is attached to the inner wall surface of the third wall 133, so as to limit the body 31 of the sealing member 3 from twisting, moving or exposing the limiting receiving portion 13 in the limiting receiving cavity 103, thereby improving the sealing performance. Simultaneously, the free ends of the first protruding part 231 and the second protruding part 232 are in sealing connection with the body 31 positioned at two sides of the protruding rib 322, and the sealing element 3 is further positioned, so that the sealing effect is improved.

Referring to fig. 9 to 10, in the embodiment of the application, a distance from the first surface 2311 to the third surface 2321 is a limiting groove width W1; the distance from the second surface 2312 to the fourth surface 2322 is the protrusion width W2, and the limit groove width W1 is 1/3 to 1/2 of the protrusion width W2. If the width W1 of the limiting groove is smaller than 1/3 of the width W2 of the protruding portion, the width W1 of the limiting groove is too narrow, the protruding point 321 cannot enter the limiting groove 201 and be fixed, and the sealing member 3 and the cover 2 cannot be effectively sealed. If the width W1 of the limiting groove is greater than 1/2 of the width W2 of the protruding portion, the width W1 of the limiting groove is too wide, the widths of the first protruding portion 231 and the second protruding portion 232 are too narrow, and the structural strength of the first protruding portion 231 and the second protruding portion 232 is reduced, so that deformation is easy to occur, and the tightness between the sealing element 3 and the cover body 2 is not facilitated.

Referring to fig. 10 and 12 to 13, in the embodiment of the present application, the width of the rib is 0.2mm to 0.8mm smaller than the width W1 of the limiting groove. The rib 322 is rectangular, and the rib 322 includes a first vertical surface 3221 and a second vertical surface 3222 opposite to the first vertical surface 3221, the first vertical surface 3221 being parallel to the second vertical surface 3222. Definition: the width of the ribs is the distance from the first vertical surface 3221 to the second vertical surface 3222, i.e., the rib width W3. The first vertical surface 3221 faces the first surface 2311 and the second vertical surface 3222 faces the third surface 2321. If the difference between the width W3 of the bead and the width W1 of the limiting groove is smaller than 0.2mm, the gaps between the first vertical surface 3221 and the first surface 2311, and the gaps between the second vertical surface 3222 and the third surface 2321 of the bead 322 are too small, and the bead 322 cannot enter the limiting groove 201 to perform a positioning function, so that the sealing element 3 is twisted and moved in the limiting accommodating cavity 103, and leakage occurs. If the difference between the width W3 of the rib and the width W1 of the limiting groove is greater than 0.8mm, the gaps between the first vertical surface 3221 and the first surface 2311 of the rib 322, and the gaps between the second vertical surface 3222 and the third surface 2321 are too large, and the rib 322 moves in the limiting groove 201, so that the positioning function cannot be achieved, and leakage is also easily caused.

Referring to fig. 10 and 12 to 13, the width of the bump is 0.2mm to 5mm larger than the width of the limit groove. The bump 321 is rectangular, and the bump 321 includes a third vertical surface 3211 and a fourth vertical surface 3212 opposite to the third vertical surface 3211, the third vertical surface 3211 being parallel to the fourth vertical surface 3212. Definition: the width of the bump is the distance from the third vertical surface 3211 to the fourth vertical surface 3212, i.e., the bump width W4. The third vertical face 3211 faces the first face 2311 and the fourth vertical face 3212 faces the third face 2321. If the bump width W4 is smaller than 0.2mm than the limit groove width W1, the friction force between the third vertical surface 3211 and the first surface 2311, and the fourth vertical surface 3212 and the third surface 2321 of the bump 321 when in fit is too small, the bump 321 is easy to slide out of the limit groove 201, so that the bump 321 and the limit groove 201 cannot be in interference fit, and the sealing element 3 and the protruding portion 23 are separated, thereby affecting the sealing effect. If the bump width W4 is greater than 5mm than the limit groove width W1, the bump 321 is not easily extruded into the limit groove 201, and assembly is difficult.

Referring to fig. 8 and 10, the depth of the limiting groove 201 is 0.5mm to 2mm. According to the above description, the depth of the limiting groove 201 is the first depth H2, and if the first depth H2 is less than 0.5mm, the limiting groove 201 is too shallow, and the protruding point 321 easily slides out of the limiting groove 201, which affects the sealing performance. If the first depth H2 is greater than 2mm, the limiting groove 201 is too deep, which affects the structural strength of the first protruding portion 231 and the second protruding portion 232, and the first protruding portion 231 and the second protruding portion 232 are easily bent, which is also unfavorable for the tightness between the sealing member 3 and the protruding portion 23.

Specific assembly process of the water chamber device 100: firstly, the convex ribs 322 and the convex points 321 of the sealing element 3 are pressed into the limit groove 201 of the cover body 2, and the convex points 321 are in interference fit with the limit groove 201, so that the sealing element 3 and the cover body 2 are assembled into a whole. The cover body 2 and the sealing element 3 which are assembled into a whole are buckled on the main body 1, and the position is adjusted, so that the body 31 of the sealing element 3 is positioned in the limit accommodating cavity 103. Finally, the cover body 2 and the main body 1 are riveted through the equipment, and the cover body 2 and the main body 1 are sealed. By the above assembly process, the position of the sealing member 3 between the cover body 2 and the main body 1 is relatively fixed, and the risk of leakage between the cover body 2 and the main body 1 is reduced.

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.
