Description

Technical Field

[0001] This utility model mainly relates to the field of heat exchange equipment technology, specifically to a heat exchange chamber with a flange designed to prevent deformation. Background Technology

[0002] The heat exchange chamber is a key component of the heat exchanger, used to distribute and collect the coolant. It is typically connected to the heat exchanger core or other piping via a flange at its end. This flange usually has multiple bolt holes for securing the connection with bolts.

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] Currently, the water chamber body and flange are usually made of metal. During the process of thermal expansion and cooling contraction, due to the differences in thickness and shape between the water chamber body and flange, their degree of thermal expansion and contraction is inconsistent, which will generate huge thermal stress at the root of the flange. Under long-term action, the flange will undergo plastic deformation such as warping and flatness deviation. The internal medium pressure will also exert an outward force on the flange, exacerbating the deformation trend. Utility Model Content

[0031] Example

[0032] See attached document Figures 1-2A heat exchange chamber with flange anti-deformation includes a water chamber body 1 and a flange 2. The flange 2 is located at the open end of the water chamber body 1 and has several bolt holes 21. A reinforcing rib structure 3 is provided between the inner side wall of the flange 2 and the outer side wall of the water chamber body 1. The reinforcing rib structure 3 is evenly distributed along the circumference of the flange 2.

[0033] In this embodiment, refer to the appendix Figure 2 The reinforcing rib structure 3 includes a main radial reinforcing rib 31. The flange 2 is divided into an upper part and a lower part. The inner end of the main radial reinforcing rib 31 is connected to the outer wall of the water chamber body 1, and the outer end is connected to the inner wall of the upper part of the flange 2. The cross-section of the main radial reinforcing rib 31 is trapezoidal. The reinforcing rib structure 3 also includes an axial reinforcing ring 32 and auxiliary radial reinforcing ribs 33. The axial reinforcing ring 32 is sleeved on the outside of the water chamber body 1, and the outer wall of the axial reinforcing ring 32 is connected to the inner wall of the lower part of the flange 2. The inner end of the auxiliary radial reinforcing rib 33 is connected to the outer wall of the water chamber body 1, and the outer end is connected to the inner wall of the axial reinforcing ring 32. The auxiliary radial reinforcing ribs 33 are evenly distributed along the circumference of the axial reinforcing ring 32.

[0034] It should be noted that the main radial stiffener 31, the axial stiffener 32, and the auxiliary radial stiffener 33 form a robust support frame on the inner side of the flange 2. When the bolt preload attempts to pull the flange 2, the support frame provides a reverse support force, dispersing the locally concentrated force to the outer wall of the water chamber body 1 through the main radial stiffener 31, the axial stiffener 32, and the auxiliary radial stiffener 33, so that the entire flange 2 can bear the pressure evenly and thus remain flat. When the medium pressure inside the water chamber body 1 attempts to push the flange 2 outward, the main radial stiffener 31, the axial stiffener 32, and the auxiliary radial stiffener 33 can transmit the stress generated by the pressure from the root of the flange 2 to the more rigid water chamber body 1 and the main radial stiffener 31, the axial stiffener 32, and the auxiliary radial stiffener 33 themselves, jointly bearing the load, thereby suppressing the radial expansion and warping deformation of the flange 2.

[0035] A shell 4 is welded to the top surface of flange 2, a sealing plate 5 is welded to the top surface of shell 4, multiple water inlet channels 6 are fixedly connected to the top surface of sealing plate 5, a partition 7 is fixedly connected to the top of water inlet channels 6, and a water outlet channel 8 is fixedly connected to the top of partition 7. Multiple lugs 22 are connected to the outer wall of flange 2, and the multiple lugs 22 are evenly distributed along the circumference of flange 2.

[0036] The working principle of this utility model is as follows: Multiple main radial reinforcing ribs 31 are welded between the upper inner circumferential surface of the flange 2 and the outer wall of the water chamber body 1. Simultaneously, an axial reinforcing ring 32 is fitted onto the outside of the water chamber body 1, and multiple auxiliary radial reinforcing ribs 33 are welded between the axial reinforcing ring 32 and the lower inner circumferential surface of the flange 2, forming a robust support frame on the inner side of the flange 2. When the bolt preload attempts to pull the flange 2, the support frame provides a reverse support force, distributing the locally concentrated force through the main radial reinforcing ribs 31, the axial reinforcing ring 32, and... The auxiliary radial stiffeners 33 are distributed on the outer wall of the wider water chamber body 1, so that the entire flange 2 can bear the pressure evenly and thus remain flat. When the medium pressure inside the water chamber body 1 attempts to push the flange 2 outward, the main radial stiffeners 31, the axial stiffening ring 32 and the auxiliary radial stiffeners 33 can transmit the stress generated by the pressure from the root of the flange 2 to the more rigid water chamber body 1 and the main radial stiffeners 31, the axial stiffening ring 32 and the auxiliary radial stiffeners 33 themselves, and jointly bear the load, thereby suppressing the radial expansion and warping deformation of the flange 2.

[0037] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
