The front wall of the box body 1 is connected to a second liquid outlet pipe 16, which passes through the box body 1 and enters the first groove 9 of the first heat conducting plate 3 on the far left.

[0038] The cover plate 2 is detachably connected to the box body 1 , and the cover plate 2 can completely seal the top of the box body 1 , the top of the first heat conducting plate 3 , the top of the second heat conducting plate 4 , the top of the first connecting block 5 , and the top of the second connecting block 6 .

[0039] In this embodiment, a plurality of first heat conducting plates 3 and a plurality of second heat conducting plates 4 are arranged in the box body 1. The second heat conducting plate 4 is arranged between two adjacent first heat conducting plates 3. There is a gap between the rear wall of the first heat conducting plate 3 and the rear inner wall of the box body 1, and there is a gap between the front wall of the second heat conducting plate 4 and the front inner wall of the box body 1. In this way, the channel between the leftmost first heat conducting plate 3 and the left inner wall of the box body 1, the channel between the first heat conducting plate 3 and the second heat conducting plate 4, and the channel between the rightmost first heat conducting plate 3 and the right inner wall of the box body 1 constitute a first circulation channel. The first liquid inlet pipe 7 and the first liquid discharge pipe 8 are both connected to the first circulation channel. The top of the first circulation channel is closed when the cover plate 2 is connected to the box body 1. The cold fluid enters the first circulation channel from the first liquid inlet pipe 7 and is discharged from the first liquid discharge pipe 8.

[0040] The first connecting block 5 is connected to the rear wall of the first heat conducting plate 3, and the connection between the first heat conducting plate 3 and the rear wall of the box body 1 is realized through the first connecting block 5. The second connecting block 6 is connected to the front wall of the second heat conducting plate 4, and the connection between the second heat conducting plate 4 and the front wall of the box body 1 is realized through the second connecting block 6. There is a gap between the bottom wall of the first connecting block 5 and the second connecting block 6 and the bottom wall of the box body 1 to prevent the first connecting block 5 and the second connecting block 6 from blocking the first flow channel. By providing a first groove 9 on the first heat conducting plate 3, a second groove 10 on the first connecting block 5, a third groove 11 on the second heat conducting plate 4, and a fourth groove 12 on the second connecting block 6, and providing a plurality of first connecting grooves 13 on the top surface of the rear plate of the box body 1, and providing a plurality of second connecting grooves 14 on the top surface of the front plate of the box body 1, all the first grooves 9, the second grooves 10, the third grooves 11, the fourth grooves 12, and the first connecting grooves 13 are connected. The second communicating groove 14 forms a second circulation channel, and the second liquid inlet pipe 15 and the second liquid discharge pipe 16 are both connected to the second circulation channel. The top of the second circulation channel is closed when the cover plate 2 is connected to the box body 1. The hot fluid enters the second circulation channel through the second liquid inlet pipe 15 and is discharged from the second liquid discharge pipe 16. The hot fluid and the cold fluid realize heat exchange through the large-area first heat conducting plate 3 and the second heat conducting plate 4. In this way, the tops of the first circulation channel and the second circulation channel are in an open state when the cover plate 2 is separated from the box body 1. After dirt is formed in the first circulation channel or the second circulation channel, the cover plate 2 can be removed and the top of the box body 1 can be opened for cleaning, thereby preventing the problem of reduced heat exchange efficiency after the heat exchanger is used for a long time. At the same time, the installation of the first heat conducting plate 3, the second heat conducting plate 4, the first connecting block 5 and the second connecting block 6 in the heat exchanger are all installed when the cover plate 2 is separated from the box body 1, which is convenient to install.

[0041] In this embodiment, the depth of the front side of the first groove 9 is greater than the depth of the rear side of the first groove 9. In this embodiment, the depth of the rear side of the third groove 11 is greater than the depth of the front side of the third groove 11. This can increase the area for heat exchange between the hot fluid and the cold fluid, further improving the efficiency of heat exchange.

[0042] In this embodiment, a water temperature sensor 17 is provided on the front part of the right wall of the first heat conducting plate 3, and a first drainage pipe 8 is provided between the first heat conducting plate 3 and the second heat conducting plate 4 adjacent to its right side. The outer ends of the first drainage pipe 8 are connected to the second drainage pipe 18. A first solenoid valve is provided in the first drainage pipe 8, and a second valve is provided between the second heat conducting plate 4 and the first heat conducting plate 3 adjacent to its right side. The water temperature sensor 17 can detect the temperature of the flowing liquid and send the information to the single-chip microcomputer, which can control the opening and closing of the first solenoid valve and the second valve.

[0043] During use, the current heat exchanger can only heat a fluid of a specific temperature because the temperature of the hot fluid is fixed and the length of the heat exchange channel is fixed. The temperature of the cold fluid after heat exchange cannot be selected according to actual needs, and its use is very limited. In this embodiment, based on the above structure, a water temperature sensor 17 is provided on the right wall of the first heat conducting plate 3, and a first liquid discharge pipe 8 is provided correspondingly. A first solenoid valve is provided on the first liquid discharge pipe 8, and a second valve is provided between each second heat conducting plate 4 and the first heat conducting plate 3 adjacent to the right thereof. When the water temperature sensor 17 detects that the temperature of the fluid flowing through it reaches the required standard, the single chip microcomputer controls the first solenoid valve at the corresponding position to open and controls the second valve on its right to close. In this way, the fluid enters the second liquid discharge pipe 18 through the first liquid discharge pipe 8 at the corresponding position of the water temperature sensor 17 and is discharged through the second liquid discharge pipe 18. In this way, the outlet position of the fluid is regulated according to the required fluid temperature, thereby satisfying the function of providing fluids of different temperatures and improving the applicability of the heat exchanger.

[0044] In this embodiment, the second valve includes a cylinder 19 and a blocking plate 20. The cylinder 19 is fixed to the top wall of the cover plate 2. The blocking plate 20 is connected to the bottom end of the cylinder 19. The blocking plate 20 is movable through the cover plate 2 and can close the gap between the second heat conducting plate 4 and the adjacent first heat conducting plate 3 to its right. This facilitates the installation of the second valve.

[0045] In this embodiment, the second liquid drain pipe 18 is gradually inclined downward from the left side to the right side.

[0046] In this embodiment, the housing 1 and cover plate 2 are provided with multiple connecting units, which connect the housing 1 and cover plate 2. In this embodiment, the connecting units include a top plate, a bottom plate, and bolts. The top plate is connected to the cover plate 2, and the bottom plate is connected to the housing 1. The bolts connect the top and bottom plates. This achieves a detachable connection between the housing 1 and cover plate 2.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
