[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2This application proposes a heat exchanger shell, including a heat exchanger 1 with hot medium inlet and outlet 14 at both ends. Flanges 2 are provided at both ends of the heat exchanger 1 corresponding to the hot medium inlet and outlet 14. Cold medium inlet and outlet 3 is provided at the top of the heat exchanger 1. A shell 4 is fitted over the heat exchanger 1. Support frames 5 are provided at the bottom of both ends of the shell 4. The heat exchanger 1 is a conventional component in the prior art. The specific usage and process are all prior art and will not be described here. The shell 4 is assembled from two symmetrically arranged first protective side shells. The two ends of the two first protective side shells can be fixed to the flanges 2 at the hot medium inlet and outlet 14 by bolts 6. The outer diameter of the middle part of the shell 4 is larger than the outer diameter of its two ends, so that a cavity 7 is formed between the inner wall of the shell 4 and the outer wall of the heat exchanger 1.

[0020] In this embodiment, the outer diameter of the middle part of the shell 4 is 10%-20% larger than the outer diameter of both ends. This can effectively distribute the pressure to the flanges 2 at both ends of the heat exchanger 1 when the heat exchanger 1 is subjected to impact, thereby protecting the body of the heat exchanger 1.

[0021] Furthermore, each of the two first protective side shells is provided with a corresponding protective sleeve 8 at the cold medium inlet / outlet 3. The protective sleeve 8 is assembled from two symmetrical second protective side shells, and the two second protective side shells are respectively fixed to the corresponding first protective side shells. The protective sleeve 8 provides further protection for the cold medium inlet / outlet 3, preventing it from being damaged by external impacts. In this embodiment, the second protective side shells can be fixed to the first protective side shells by welding or other methods.

[0022] Furthermore, a sealing strip 9 is affixed to the joint of the two first protective side shells and the two second protective side shells. The sealing strip 9 can effectively prevent dust, moisture and other substances in the external environment from entering the interior of the shell 4, causing corrosion to the heat exchanger 1 body or affecting its normal operation. In this embodiment, the sealing strip 9 is made of high temperature and corrosion resistant rubber material with a thickness of 3-5 mm. When affixing the sealing strip 9, it is ensured that it is tightly fitted to the joint of the first protective side shell and the second protective side shell without any gaps.

[0023] Furthermore, a first reinforcing rib 10 is arranged in a ring array between the outer periphery of the protective sleeve 8 and the shell 4. The arrangement of the first reinforcing rib 10 can further enhance the connection strength between the shell 4 and the protective sleeve 8 and improve the load-bearing capacity of the entire heat exchanger shell. In this embodiment, the first reinforcing rib 10 is made of steel and can be fixed between the outer periphery of the protective sleeve 8 and the shell 4 by welding.

[0024] Furthermore, the top of the support frame 5 and the side facing the flange 2 are provided with a support groove 11 for the bottom of the flange 2 to abut. The support groove 11 can provide good support for the flange 2, share the support pressure of the heat exchanger 1 body, ensure that the flange 2 can be stably fixed on the support frame 5 during installation, and also facilitate the sealing connection between the flange 2 and the shell 4.

[0025] In this embodiment, a second reinforcing rib 12 is fixedly provided between the top side of the support frame 5 facing away from the flange 2 and the shell 4. The second reinforcing rib 12 can enhance the connection strength between the support frame 5 and the shell 4 and improve the stability of the entire heat exchanger shell. In this embodiment, the second reinforcing rib 12 is made of steel and can be fixed between the top side of the support frame 5 facing away from the flange 2 and the shell 4 by welding.

[0026] Furthermore, insulation cotton 13 is added inside the cavity 7. The insulation cotton 13 can effectively insulate the heat exchanger 1 body, reduce heat loss, and also alleviate the impact on the shell 4, protecting the heat exchanger 1 body. The insulation cotton 13 can be the commonly used insulation cotton in the existing technology.

[0027] The heat exchanger shell of this utility model, through the structural design of the above embodiments, has good protective performance, thermal insulation performance and load-bearing capacity, and is easy to install and disassemble, facilitating subsequent maintenance work. It can be widely used in various heat exchanger equipment.
