[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger.

[0003] When the heat exchanger is working, a hot fluid is directly injected into the interior of the heat exchanger box body, and then the cold fluid enters the box body, so that the heat in the hot fluid can be conducted into the cold fluid, thereby increasing the temperature of the cold fluid to achieve the heat exchange effect, enabling the heat to be recycled and being more energy-saving.

[0004] However, at present, the hot fluid flows through the heat exchanger box body in a direct current manner, resulting in a short flow time of the hot fluid in the heat exchanger, so that the heat transfer time of the hot fluid is less, reducing the heat exchange efficiency. For this reason, we propose an energy-saving circulating heat exchanger. Summary of the Utility Model

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides an energy-saving circulating heat exchanger as Figures 1 - 5 shown, which includes a box body 101 and a flow channel assembly. An over-liquid mechanism is arranged inside the box body 101. A fluid with a higher temperature is filled inside the box body 101, and then a fluid with a lower temperature enters the over-liquid mechanism, so that the fluid with a higher temperature;

[0025] In a preferred embodiment, the flow channel assembly is arranged inside the box body 101. The flow channel assembly is used to guide the flow of the hot fluid inside the box body 101. The flow channel assembly includes a plurality of first partition members 201 and second partition members 202. The front and back surfaces of the first partition member 201 are fixedly connected to the inner wall of the box body 101, the top end of the first partition member 201 is fixedly connected to the inner wall of the box body 101, the front and back surfaces of the second partition member 202 are fixedly connected to the inner wall of the box body 101, the bottom end of the second partition member 202 is fixedly connected to the inner wall of the box body 101. The first partition member 201 and the second partition member 202 are arranged in an interleaved manner. Through the interleaved first partition member 201 and second partition member 202, the hot fluid in the box body 101 will move in a continuous S shape through the flow channels formed by the plurality of first partition members 201 and second partition members 202, thereby increasing the residence time of the hot fluid in the box body 101, and thus improving the heat exchange efficiency.

[0026] Among them, the over-liquid mechanism includes a liquid passing pipe 501. The middle part of the liquid passing pipe 501 is arranged in a continuous S shape. The fluid with a lower temperature enters the inside of the box body 101 through the liquid passing pipe 501, so that the heat of the hot fluid in the box body 101 can be transferred to the fluid in the liquid passing pipe 501, thereby performing heat exchange and avoiding waste of heat.

[0027] Among them, the first partition member 201 includes a first fixing frame 301 and a first fixing plate 302. The first fixing frame 301 is arranged in an inverted U shape. The first fixing plate 302 is fixedly connected to the inner wall of the first fixing frame 301. The front and back surfaces of the first fixing frame 301 are both fixedly connected to the inner wall of the box body 101, the top end of the first fixing frame 301 is fixedly connected to the inner wall of the box body 101. A plurality of fixing holes 601 are respectively formed on one side of the first fixing plate 302. The outer wall of the liquid passing pipe 501 is fixedly inserted and connected to the inner walls of the plurality of fixing holes 601. The material of the first fixing plate 302 is copper. Through the combined setting of the first fixing frame 301 and the first fixing plate 302, when the hot fluid contacts the first fixing plate 302, the heat can be more efficiently transferred from the copper-made first fixing plate 302 to the fluid in the liquid passing pipe 501. At the same time, since the first fixing frame 301 is made of a material with poor heat conduction efficiency, the heat conduction out through the inner wall of the box body 101 can be effectively reduced, further ensuring the heat exchange efficiency of the heat exchanger.

[0028] Among them, the second partition member 202 includes a second fixing frame 401 and a second fixing plate 402. The second fixing frame 401 is arranged in a U shape. The second fixing plate 402 is fixedly connected to the inner wall of the second fixing frame 401. The front and back surfaces of the second fixing frame 401 are both fixedly connected to the inner wall of the box body 101, the bottom end of the second fixing frame 401 is fixedly connected to the inner wall of the box body 101. A plurality of fixing holes 601 are respectively formed on one side of the second fixing plate 402. The outer wall of the liquid passing pipe 501 is fixedly inserted and connected to the inner walls of the plurality of fixing holes 601. The material of the second fixing plate 402 is copper. Through the combined setting of the second fixing frame 401 and the second fixing plate 402, when the hot fluid contacts the second fixing plate 402, the heat can be more efficiently transferred from the copper-made second fixing plate 402 to the fluid in the liquid passing pipe 501. At the same time, since the second fixing frame 401 is made of a material with poor heat conduction efficiency, the heat conduction out through the inner wall of the box body 101 can be effectively reduced, further ensuring the heat exchange efficiency of the heat exchanger.

[0029] Among them, both ends of the liquid passing pipe 501 respectively penetrate the inner wall of the box body 101 and extend to the outer wall of the box body 101. A first connecting ring 701 is fixedly sleeved on the end of the liquid passing pipe 501. A plurality of first connecting holes 702 are arranged in an annular array on one side of the first connecting ring 701. Through the setting of the first connecting ring 701 and the first connecting holes 702, it is convenient to connect the external device to the liquid passing pipe 501, so that the fluid with a lower temperature of the external device can stably enter the liquid passing pipe 501 and be stably discharged to the corresponding device after heat exchange inside the box body 101.

[0030] Among them, connecting pipes 801 are fixedly inserted and connected to both the top end and the bottom end of the box body 101. A second connecting ring 802 is fixedly sleeved at the end of the connecting pipe 801. A plurality of second connecting holes 803 are formed in a circular array at the top end of the second connecting ring 802. Through the settings of the connecting pipe 801, the second connecting ring 802, and the second connecting holes 803, it is convenient to connect the box body 101 with external equipment, enabling the water with higher temperature to stably enter and discharge from the box body 101.

[0031] Among them, mounting plates 901 are symmetrically and fixedly connected to the side edges of the outer wall of the box body 101. Mounting holes 902 are formed on the front surface of the mounting plates 901. Through the settings of the mounting plates 901 and the mounting holes 902, it is convenient to fix the box body 101 to an external mounting surface, enabling the heat exchanger to work stably.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
