[0024] Example

[0025] like Figures 1-4As shown, an embodiment of the present invention provides an insert-type heat exchanger, including a heat exchanger body 1, a heat exchange chamber 2 in the heat exchanger body 1, an inlet pipe 3 and an outlet pipe 4 at the upper and lower ends of the heat exchanger body 1 respectively, a connecting pipe 6 in the heat exchanger body 1, a heat exchange tube 7 in the heat exchange chamber 2, one end of the heat exchange tube 7 being connected to a U-shaped pipe 8, and a mounting plate on the side of the heat exchanger body 1 to make it a whole, the mounting plate having mounting holes;

[0026] Heat exchanger body 1

[0027] Structural design features: The interior is equipped with a heat exchange chamber 2, with an inlet pipe 3 and an outlet pipe 4 at the top and bottom respectively. There is a mounting plate on the side with mounting holes, and the whole structure is integrated through the mounting plate.

[0028] Function: As the main structure of the heat exchanger, it provides space and support for the heat exchange process. The mounting plate facilitates the installation and fixation of the entire heat exchanger. The inlet pipe 3 and outlet pipe 4 are used for the entry and exit of the medium.

[0029] Heat exchange chamber 2

[0030] Structural design features: Both ends are side plates, and heat exchange tubes 7 are placed inside.

[0031] Function: Provides space for placing heat exchange tube 7. The side plate is used to fix the position of heat exchange tube 7 and is the main place for heat exchange.

[0032] Inlet pipe 3 and outlet pipe 4

[0033] Structural design features: located at the upper and lower ends of the heat exchanger body 1 respectively, penetrating the protective plate 5 and connecting to the inside of the heat exchanger body 1, and connected to the heat exchanger body 1 by a connecting pipe 6.

[0034] Function: Inlet pipe 3 is used to introduce the medium that needs heat exchange, and outlet pipe 4 is used to discharge the medium after heat exchange. It is the channel for the medium to enter and exit the heat exchanger.

[0035] Protective plate 5

[0036] Structural design features: It is installed on the side of the mounting plate, with inlet pipe 3 and outlet pipe 4 passing through it.

[0037] Function: It protects the inlet pipe 3 and outlet pipe 4, and also provides some protection and support for the overall structure of the heat exchanger.

[0038] Connecting pipe 6

[0039] Structural design features: Not in heat exchange chamber 2, but connected to inlet pipe 3, outlet pipe 4 and heat exchange tube 7. The connected heat exchange tube 7 is a double tube.

[0040] Function: It serves to connect and distribute the medium, allowing the medium to flow reasonably between the inlet pipe 3, outlet pipe 4 and heat exchange pipe 7. The dual-pipe design is beneficial to improving heat exchange efficiency or the uniformity of medium distribution.

[0041] Heat exchanger tube 7

[0042] Structural design features: Located in heat exchange chamber 2, one end is connected to U-shaped tube 8, and it is connected by connecting pipe 6 and has a double tube structure.

[0043] Function: It is a key component for heat exchange, in which the medium flows and exchanges heat with the medium in heat exchange chamber 2. The double tube structure increases the heat exchange area or improves the heat exchange effect.

[0044] U-shaped tube 8

[0045] Structural design features: Installed in heat exchange tube 7, located outside the side plate.

[0046] Function: To change the flow path of the medium and increase the residence time of the medium in the heat exchange tube 7, thereby improving the heat exchange efficiency.

[0047] During operation, the medium enters through inlet pipe 3, which passes through the protective plate 5 and connects to the interior of the heat exchanger body 1. Within the heat exchanger body 1, it is distributed via connecting pipe 6. Connecting pipe 6 is not located in the heat exchange chamber 2 but connects to a double-tube heat exchanger 7, which transports the medium to the heat exchanger 7 located in the heat exchange chamber 2. Side plates at both ends of the heat exchange chamber 2 fix the position of the heat exchanger 7, providing a space for heat exchange. A U-shaped pipe 8 connected to one end of the heat exchanger 7 is located outside the side plate, which can change the medium flow path and increase the residence time. After heat exchange between the medium in the heat exchanger 7 and the medium in the heat exchange chamber 2, the medium is discharged through connecting pipe 6 and then through outlet pipe 4. Outlet pipe 4 also passes through the protective plate 5 and connects to the interior of the heat exchanger body 1, thus completing the entire heat exchange process.

[0048] like Figure 2 As shown, in some embodiments, a protective plate 5 is installed on the side of the mounting plate, and the inlet pipe 3 and outlet pipe 4 pass through the protective plate 5 and connect to the interior of the heat exchanger body 1; it plays a protective role for the inlet pipe 3 and outlet pipe 4, and may also play a certain protective and support role for the overall structure of the heat exchanger.

[0049] like Figure 3 As shown, in some embodiments, the connecting pipe 6 is not in the heat exchange chamber 2, and the two ends of the heat exchange chamber 2 are side plates used to fix the position of the heat exchange tube 7; it is not in the heat exchange chamber 2. This design may be to avoid unnecessary heat exchange between the connecting pipe 6 and the medium in the heat exchange chamber 2, and also to facilitate its connection to the external inlet pipe 3 and outlet pipe 4, as well as the reasonable distribution of the medium to the heat exchange tube 7.

[0050] like Figure 3As shown, in some embodiments, the heat exchange tube 7 connected to the connecting pipe 6 is a double-tube configuration; the connecting pipe 6 can better distribute the medium to the two heat exchange tubes 7, which may help improve the uniformity of the medium flow in the heat exchange tubes 7, thereby improving the overall heat exchange efficiency.

[0051] like Figure 4 As shown, in some embodiments, the U-shaped tube 8 is installed in the heat exchange tube 7 and located outside the side plate; it is installed in the heat exchange tube 7 and located outside the side plate. Installing it in the heat exchange tube 7 can change the flow path of the medium in the heat exchange tube 7, causing the medium to change direction and stagnate at the U-shaped tube, increasing the residence time of the medium in the heat exchange tube 7, thereby giving the medium more opportunities to exchange heat with the heat exchange medium outside the heat exchange tube 7.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
