[0019] In the description of the utility model, it should be explained that the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and the above description is simplified for the convenience of describing the utility model, and does not indicate or imply that the indicated device or element must have a specific orientation, a specific orientation and operation, so it cannot be understood as a limitation on the utility model.

[0020] The singular forms "a", "said" and "the" used in the specification contain plural forms unless it is clear that the singular forms are used. The terms "include", "contain" and "have" used in the specification indicate the existence of the claimed features, but do not exclude the existence of one or more other features.

[0021] In the specification, when it is stated that an element is "on", "fixed" to, "connected" to, "joined" to another element, etc., the element can be directly on, fixed to, connected to, joined to or in contact with the other element, or there may be an intermediate element. In the specification, when a feature is arranged "adjacent" to another feature, it may mean that the feature has a part overlapping with the adjacent feature or a part located above or below the adjacent feature.

[0022] It can be understood that although terms such as "first", "second", etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a first element can be referred to as a second element without departing from the teachings of the concept of the present application.

[0023] Exemplary embodiments of the present application will be described hereinafter with reference to the accompanying drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals denote the same or functionally identical elements.

[0024] Figure 1 and Figure 2 The overall structure of such a gas-cooled tube bundle is shown. This tube bundle mechanism is arranged in the cooler box body 1, and the box body 1 is filled with a coolant. The gas enters from the inlet end head 10, is cooled in the box body 1, and then flows out from the exhaust end head 20. A tube bundle group is connected between the inlet end head 10 and the exhaust end head 20. The gas reciprocates between the inlet end head 10 and the exhaust end head 20 through the tube bundle group, so as to achieve the maximum cooling effect.

[0025] With reference to Figures 3 to 5 , the tube bundle group is composed of a first tube group 31, a second tube group 32 and a third tube group 33. A first flow guiding module 13 for guiding the gas into the tube bundle group is arranged on the inlet end head 10. Similarly, a second flow guiding module 23 for guiding the gas out of the tube bundle group is arranged on the exhaust end head 20. Specifically, an air inlet passage 12 connected to the air inlet end 11 is arranged in the inlet end head 10, and an exhaust passage 22 connected to the exhaust end 21 is arranged in the exhaust end head 20. A first through-hole groove 15 and a first flow guiding groove 14 are respectively formed on the first flow guiding module 13. The first through-hole groove 15 enables the air inlet passage 12 to pass through the first flow guiding module 13 and be connected to the tube bundle group. The first flow guiding groove 14 is in a "U" shape so as to simultaneously accommodate and connect a pair of tube groups. Similarly, a second through-hole groove 25 and a second flow guiding groove 24 are also formed on the second flow guiding module 23.

[0026] Specifically, the first guide channel 14 connects the second pipe group 32 and the third pipe group 33, while the second guide channel 24 connects the first pipe group 31 and the second pipe group 32. The first pipe group 31 allows air to flow from the intake end 11 into the pipe group through the first through-hole groove 15, and finally flows out through the third pipe group 33 via the second through-hole groove 15 and the exhaust passage 22. Furthermore, the first guide module 13 and the second guide module 23 have essentially the same structure, but are offset circumferentially by overlapping their side profile projections, thus creating a deflection angle. In a preferred embodiment, the deflection angle is 36°. The first pipe group 31, the second pipe group 32, and the third pipe group 33 are all fixed to the first guide module 13 and the second guide module 23 using brazing. Due to the small space at the welding point, conventional welding is difficult, and fusion welding might damage the sealing structure. Therefore, brazing is used. During brazing, only the filler metal melts, not the base material, thus avoiding damage to the connection structure.
