Description

Technical Field

[0001] The utility model belongs to the technical field of constant temperature water exchange devices and relates to a modular coupled water exchange and heat exchange device. Background Art

[0002] Most of the existing aquarium water-changing products adopt a separate design, that is, the equipment for water replenishment, the equipment for drainage, and the equipment for temperature control are installed and used independently of each other. Each type of equipment has its own separate water pipeline, and many pipelines are installed in the container, which takes up the container space and reduces the aesthetics of the aquarium products. In addition, in order to work with the water level inside the container, the above-mentioned types of equipment also need to be equipped with additional water level sensors, which further causes equipment redundancy. Although in recent years, integrated water-changing equipment for replenishment and drainage has appeared, which realizes the sharing of a set of pipelines and sensors for water replenishment and drainage operations, but overall, the pipelines of the current integrated water-changing equipment for pumping and draining still cannot be interoperated with the pipelines of the filtering and temperature control equipment on the aquarium container, which will still cause pipeline redundancy and affect the aesthetics of the aquarium container.

[0003] Therefore, in view of the defects that the existing water replenishment device, drainage device and temperature control device are independent of each other and the pipelines are not compatible with each other, resulting in pipeline redundancy and affecting the aesthetics of the aquarium container, the utility model discloses a modular coupled water and heat exchange device. Utility Model Content

[0004] The purpose of the utility model is to provide a modular coupled water exchange and heat exchange device to achieve the coupling of temperature control and drainage, so that the drainage operation and the temperature control function share a set of circulation pipelines and power equipment, maximize the resource utilization of the whole system, avoid the installation of redundant pipelines and sensors inside the aquarium container, save the internal space of the aquarium container, and ensure the aesthetics of the aquarium container.

[0009] The first end of the three-way valve sucks water from the external water source and transports the water to the peristaltic pump through the third end of the three-way valve. Under the forward action of the peristaltic pump, the water is transported from the outlet end of the peristaltic pump to the inlet end of the non-self-priming circulating water pump to participate in the circulating heat exchange, and after the circulating heat exchange, it is input into the container from the outlet end of the water cooling assembly to realize water replenishment for the container.

[0015] In order to better implement the present utility model, further, two water temperature sensors are provided inside the sensor clamp, and the two water temperature sensors are symmetrically attached to both sides of the circulating pipeline with respect to the neutral plane of the circulating pipeline.

[0016] In order to better implement the present utility model, further, a pressure and flow sensor is provided between the outlet end of the water cooling assembly and the inlet end of the non-self-priming circulating water pump.

[0019] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0020] (1) The present utility model couples the functions of water replenishment and drainage. The same set of pipeline and peristaltic pump are used for the water replenishment operation and the drainage operation of the container. When comprehensively implementing the water replenishment and drainage operations, the resource utilization rate is improved, and the volume of the water changing device is further reduced;

[0021] (2) The utility model couples the water changing device with the constant temperature heat exchange device, so that the water changing device and the constant temperature heat exchange device share a set of circulating pipelines.

[0022] (3) By setting a pressure and flow sensor, the utility model continuously calculates the water level inside the container by detecting the change in water flow pressure, and then efficiently adjusts the water changing device through the water level to timely replenish or drain the water in the container. At the same time, the pressure and flow sensor is coupled and installed inside the installation housing of the constant temperature heat exchange device, eliminating the need to additionally install a water level sensor on the container, avoiding redundancy in the internal structure of the aquarium container and enhancing the aesthetics of the aquarium container.

[0023] (4) The water changer housing of the water changing device is detachably installed on the installation housing of the constant temperature heat exchange device, realizing convenient modular splicing installation and subsequent maintenance and disassembly between the water changing device and the constant temperature heat exchange device, making it more convenient and fast to use.

[0041] Example 1:

[0042] A modularly coupled water-changing and heat-exchanging device in this embodiment is as shown in Figure 1 , Figure 2 , Figure 5 , Figure 6 . It includes a water-changing device 1 and a constant-temperature heat-exchanging device 2. The water-changing device 1 includes a water-changer housing 11. Inside the water-changer housing 11, a three-way valve 12 and a peristaltic pump 13 are provided. The constant-temperature heat-exchanging device 2 includes an installation housing 21. Inside the installation housing 21, a non-self-priming circulating pump 22 and a water-cooling component 23 are provided. The first end of the three-way valve 12 is the inlet end, the second end of the three-way valve 12 is the outlet end. Both the first end and the second end of the three-way valve 12 are connected to the first end of the peristaltic pump 13 through the third end. The second end of the peristaltic pump 13 is connected to the inlet end of the non-self-priming circulating pump 22. The outlet end of the non-self-priming circulating pump 22 is connected to the water-cooling component 23 through a circulation pipeline. A temperature sensing device 24 is provided on the circulation pipeline. The water-changer housing 11 is detachably coupled and assembled outside the installation housing 21.

[0043] The water-changer housing 11 is assembled outside the installation housing 21 to form an integrated structure. When the water-changer housing 11 and the installation housing 21 are assembled in place, the second end of the peristaltic pump 13 is communicated with the inlet end of the non-self-priming circulating pump 22. The inlet end of the non-self-priming circulating pump 22 is connected to a container, such as a fish tank, through a pipeline. The outlet end of the water-cooling component 23 is connected to a container, such as a fish tank, through a pipeline. When the non-self-priming circulating pump 22 works, it sucks the water in the container into the circulation pipeline and makes the water flow along the circulation pipeline to the water-cooling component 23. The water-cooling component 23 is arranged in contact with the heat dissipation device. When the water flows through the water-cooling component 23, it exchanges heat with the heat dissipation device. The heat-exchanged water flows back to the container through the outlet end of the water-cooling component 23 to realize circulation. The temperature sensing device 24 is used to detect the water temperature in the circulation pipeline in real time, and the heat exchange power of the water-cooling component 23 is regulated by the water temperature, so as to control the water temperature in the container in a relatively constant state through the circulating water.

[0044] When it is necessary to carry out a water-changing operation inside the container, the peristaltic pump 13 rotates forward. Through the forward power, the water inlet pipeline connected to the first end of the three-way valve 12 sucks water from an external water source. The sucked water enters the peristaltic pump 13 through the third end of the three-way valve 12 and is further transported to the inlet end of the non-self-priming circulating pump 22 to participate in the heat exchange circulation, and finally flows back to the container to realize water replenishment in the container. The peristaltic pump 13 rotates reversely. Through the reverse power, the second end of the peristaltic pump 13 sucks the water at the inlet end of the non-self-priming circulating pump 22. The sucked water enters the drainage pipeline through the peristaltic pump 13 and the second end of the three-way valve 12 and is discharged, realizing drainage of the container.

[0045] Example 2:

[0046] A modularly coupled water exchange and heat exchange device, improved on the basis of Embodiment 1, as Figure 3 and Figure 4 shown, a bypass water supply valve 4 is further provided on the circulation pipeline. As Figures 9 - 12 shown, a main flow channel 41 is provided inside the bypass water supply valve 4. The inlet end of the main flow channel 41 is connected to the circulation pipeline, and the outlet end of the main flow channel 41 is connected to the water cooling assembly 23; a bypass pipeline 42 is communicated on one side of the main flow channel 41, and a bypass power device 43 is provided on the bypass pipeline 42. A valve flap 44 that rotates to open or rotate to close under the power provided by the bypass power device 43 is provided inside the main flow channel 41.

[0047] Under normal water supply conditions, water flows from the inlet end of the main flow channel 41 to the outlet end of the main flow channel 41 and does not flow through the bypass pipeline 42. At this time, the valve flap 44 is opened under the action of the water flow inside the main flow channel 41 and does not hinder the water flow transportation, realizing normal water supply. When there is no water diversion inside the non-self-priming circulation pump 22, at this time, the bypass power device 43 is turned on, so that the water flow that should flow through the main flow channel 41 flows through the bypass pipeline 42. A part of the water flow flowing through the bypass pipeline 42 flows to the outlet end of the main flow channel 41, and the other part acts on the side of the valve flap 44 far from the inlet end of the main flow channel 41, so that the valve flap 44 closes the main flow channel 41. At this time, under the power provided by the bypass power device 43, it is ensured that the non-self-priming circulation pump 22 can be normally filled with water.

[0048] Furthermore, the inlet end of the bypass pipeline 42 is provided on the side of the valve flap 44 close to the inlet end of the main flow channel 41, and the outlet end of the bypass pipeline 42 is provided on the side of the valve flap 44 close to the outlet end of the main flow channel 41. That is, the inlet end and the outlet end of the bypass pipeline 42 are located between the inlet end and the outlet end of the main flow channel 41, and the valve flap 44 is located between the inlet end and the outlet end of the bypass pipeline 42.

[0049] Other parts of this embodiment are the same as those of Embodiment 1, so they will not be elaborated here.

[0050] Embodiment 3:

[0051] A modularly coupled water exchange and heat exchange device, improved on the basis of Embodiment 1 or 2, as Figure 4 shown, the water cooling assembly 23 includes a water cooling head 231, a refrigeration sheet 232, and a hot and cold end sensor 233. An inner part of the water cooling head 231 is provided with a heat exchange cavity. The inlet end of the heat exchange cavity is connected to the outlet end of the bypass water supply valve 4, and the outlet end of the heat exchange cavity is provided with a pipeline extending to one side of the inlet end of the non-self-priming circulation pump 22; a refrigeration sheet 232 is provided on one side of the water cooling head 231 close to the radiator, and a hot and cold end sensor 233 is provided on the side of the water cooling head 231 far from the radiator.

[0052] The heat exchange cavity is internally provided with zigzag guide vanes. Through the guiding action of the guide vanes, the flow path of the water flow in the heat exchange cavity is extended, so that the water flow can fully exchange heat with the refrigerating sheet 232 inside the heat exchange cavity. The water temperature in the heat exchange cavity inside the water-cooled head 231 is detected by the hot and cold end sensor 233. According to the detected water temperature and the set water temperature, it is judged whether the water inside the heat exchange cavity needs to be heated or cooled. Furthermore, the direction of the current input to the refrigerating sheet 232 is changed. When a positive current is input, the refrigerating sheet 232 absorbs heat from the radiator and transfers it to the water-cooled head 231, so that the water inside the heat exchange cavity is heated. When a reverse current is input, the refrigerating sheet 232 absorbs heat from the heat exchange cavity and transfers it to the radiator, so that the water inside the heat exchange cavity is cooled. Its specific principle has been described in detail in the patent application with the application number "CN202320127821.6", and will not be elaborated here.

[0053] Furthermore, two water-cooled heads 231 are arranged in series in sequence, and the circulation pipeline is in the area between the two water-cooled heads 231.

[0054] Other parts of this embodiment are the same as those of Embodiment 1 or 2, so they will not be elaborated here.

[0055] Embodiment 4:

[0056] A modularly coupled water-changing heat exchange device, which is improved on the basis of any one of Embodiments 1-3, as Figure 3 shown, the temperature sensing device 24 includes a sensor fixture 241 and a water temperature sensor 242. The sensor fixture 241 is wrapped outside the circulation pipeline. The water temperature sensor 242 is fixedly arranged inside the sensor fixture 241, and the water temperature sensor 242 is attached to the outside of the circulation pipeline.

[0057] The sensor fixture 241 includes a fixture base and a fixture cover plate. The fixture base is arranged at the bottom of the circulation pipeline, and the fixture cover plate is located at the top of the circulation pipeline and is snap-fitted on the fixture base to form a cavity for installing the water temperature sensor 242. A support plate for fixedly supporting the water temperature sensor 242 is arranged in the cavity, so as to attach and fix the water temperature sensor 242 to the outside of the circulation pipeline, and the circulating water temperature in the circulation pipeline can be detected in real time through the water temperature sensor 242.

[0058] Further, two water temperature sensors 242 are provided inside the inductor fixture 241, and the two water temperature sensors 242 are symmetrically attached to both sides of the circulation pipeline with respect to the neutral plane of the circulation pipeline. By symmetrically arranging the two water temperature sensors 242, the water temperature error caused by local single-point detection is avoided, ensuring that the final detected result of the circulating water temperature is more accurate. Moreover, the two water temperature sensors 242 form a redundant configuration. Even if one of the water temperature sensors 242 fails, as long as the other water temperature sensor 242 can work normally, the normal operation of the entire device can be ensured.

[0059] Other parts of this embodiment are the same as any one of Embodiments 1-3, so they will not be described in detail here.

[0060] Embodiment 5:

[0061] A modular-coupled water-changing and heat-exchanging device is improved on the basis of any one of Embodiments 1-4, as Figure 2 shown, a pressure flow sensor 5 is provided between the outlet end of the water-cooling component 23 and the inlet end of the non-self-priming circulation water pump 22.

[0062] When there is no water flow in the circulation pipeline, at this time, the pressures at the outlet end of the water-cooling component 23 and the inlet end of the non-self-priming circulation water pump 22 are the same. When the non-self-priming circulation water pump 22 works, under the action of the power of the non-self-priming circulation water pump 22, the pressure at the inlet end of the non-self-priming circulation water pump 22 will be less than the pressure at the outlet end of the water-cooling component 23, resulting in a pressure difference. Under the action of this pressure difference, water enters the circulation pipeline and flows along the circulation pipeline. The pressure flow sensor 5 is used to detect this pressure difference, and the pressure difference is proportional to the water flow in the circulation pipeline. Therefore, only by detecting the pressure difference can the water flow in the circulation pipeline be inversely deduced and calculated. The specific structure and operating principle of the pressure flow sensor 5 are prior art and not the improvement points of this application, so its specific structure and detailed operating principle will not be described here.

[0063] Other parts of this embodiment are the same as any one of Embodiments 1-4, so they will not be described in detail here.

[0064] Embodiment 6:

[0065] A modular-coupled water-changing and heat-exchanging device is improved on the basis of any one of Embodiments 1-5, as Figure 2 and Figure 6 shown, a water inlet joint A1 is connected to the first end of the three-way valve 12, a drain joint A2 is connected to the second end of the three-way valve 12, and check valves A3 are provided between the first end of the three-way valve 12 and the water inlet joint A1 and between the second end of the three-way valve 12 and the drain joint A2 respectively.

[0066] As Figure 7As shown in the figure, in the water replenishment state, the peristaltic pump 13 rotates forward to generate power, enabling external water to enter the inside of the three-way valve 12 through the water inlet joint A1 at the first end of the three-way valve 12, and then enter the peristaltic pump 13 through the third end of the three-way valve 12. Under the action of the forward rotation of the peristaltic pump 13, the water is conveyed from the second end of the peristaltic pump 13 to the inlet end of the non-self-priming circulation pump 22.

[0067] As Figure 8 As shown in the figure, in the drainage state, the peristaltic pump 13 rotates reversely to generate reverse power, enabling the water inside the container to enter the peristaltic pump 13 through the second end of the peristaltic pump 13, then enter the three-way valve 12 through the third end of the three-way valve 12, and finally be discharged through the drainage joint A2 at the second end of the three-way valve 12.

[0068] Furthermore, an installation groove corresponding to the water changer housing 11 is provided on the outside of the installation housing 21. A matching portion 211 is provided on the groove wall of the installation groove. A quick-connect portion 111 corresponding to the matching portion 211 is provided on the side wall of the water changer housing 11. A locking mechanism 3 is provided between the water changer housing 11 and the installation groove.

[0069] After the water changer housing 11 is installed in place in the installation groove, the locking structure 3 located at the top of the quick-connect portion 111 is correspondingly and cooperatively connected with the locking port provided on the groove wall of the installation groove, thereby locking and fixing the water changer housing 11 inside the installation groove. When it is necessary to disassemble the water changing device 1, only need to take out the locking mechanism 3 from the locking port, and then the water changer housing 11 can be conveniently disassembled from the installation groove.

[0070] Other parts of this embodiment are the same as any one of Embodiments 1-5, so they will not be described in detail.

[0071] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification and equivalent change made to the above embodiments based on the technical essence of the present invention all fall within the protection scope of the present invention.
