Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a semi-volumetric heat exchanger for improving heat exchange efficiency. Background Technology

[0002] A semi-volumetric heat exchanger is a heat exchange device that falls between a volumetric heat exchanger and a rapid heat exchanger. Structurally, it mainly consists of a water storage tank, a heating device, and other components. The water storage tank is used to store a certain amount of water, and its outer wall has a first hot water outlet and a first cold water inlet, which are used to output hot water and input cold water, respectively.

[0003] An existing Chinese patent (publication number: CN206131798U) proposes a semi-volumetric heat exchanger to improve heat exchange efficiency. It mainly improves the heat exchange efficiency of the heat medium by setting the flow guiding component so that the water flows along the heat conducting body, ensuring that the water and the heat exchange component are in full contact. At the same time, the flow guiding component has a clever and reasonable structural design, is easy to install, and has stable and reliable flow guiding performance.

[0004] The aforementioned patented arc-shaped body and the inner arc-shaped wall form a channel for water to flow through. The elastic arms at both ends constitute a stop that prevents water from flowing into the outer clearance groove. This allows water to flow only along the channel between the arc-shaped body and the inner arc-shaped wall, thereby restricting the water flow path.

[0005] However, in practical applications, the flow guiding component of the above-mentioned patent relies on the elasticity of the elastic positioning plate to restrict the water flow. However, during long-term use, the elastic material may experience fatigue, aging and other problems. For example, after long-term water flow impact and temperature changes, the elasticity of the elastic arm may weaken, causing the stop part to be unable to effectively prevent the water from flowing to the outer clearance groove, thereby affecting the flow guiding effect and reducing the heat exchange efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a semi-volumetric heat exchanger that improves heat exchange efficiency, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a semi-volumetric heat exchanger for improving heat exchange efficiency, comprising a fixed base plate, wherein a flow guiding component is provided on the fixed base plate;

[0008] The flow guiding assembly includes an outer chamber, a cooling water chamber fixedly connected to the outer chamber, a water pump fixedly connected to the cooling water chamber, an infusion pipe fixedly connected to the water pump, a metal pipe fixedly connected to the end of the infusion pipe away from the water pump, an inner chamber fixedly connected to the metal pipe, a water storage chamber fixedly connected to the end of the metal pipe away from the fixed base plate, a rotating component rotatably connected inside the water storage chamber, a fan blade fixedly connected to the rotating component, a heat exchange chamber fixedly connected inside the water storage chamber, a water pipe fixedly connected to the heat exchange chamber, a conical frame fixedly connected to the water storage chamber, a sealing bead slidably connected inside the conical frame, a sliding component slidably connected to the conical frame, a spring fixedly connected to the bottom of the sliding component, the spring fixedly connected to the outer chamber, a hot water chamber fixedly connected to the outer chamber, a second mounting plate provided on the hot water chamber, a fixing ring fixedly connected inside the water storage chamber, and a filter screen fixedly connected inside the heat exchange chamber.

[0009] In a preferred embodiment, a handheld device is fixedly connected to the water storage tank, and the side of the handheld device away from the water storage tank is fixedly connected to the hot water tank.

[0010] The above technical solution is adopted: by setting up a hand-held part, the outer chamber can be rotated by external force when in use, so that the sliding part contacts the sealing bead, and the sealing bead is pushed out under the action of the spring, so that hot water leaks out from the conical frame.

[0011] In a preferred embodiment, the outer compartment is rotatably connected to the fixed base plate, and the inner compartment is fixedly connected to the fixed base plate.

[0012] The above technical solution is adopted: by setting the outer chamber to be rotatably connected to the fixed base plate, the outer chamber can be rotated easily, and a gap is left between the inner chamber and the outer chamber. The high temperature of the inner chamber will heat the air inside, resulting in better heat exchange effect.

[0013] In a preferred embodiment, the hot water tank has an outlet, the second mounting plate is fixedly connected to the outlet of the hot water tank, the cooling water tank has an inlet, and the first mounting plate is fixedly connected to the inlet of the cooling water tank.

[0014] The above technical solution is adopted: by setting a first installation plate and a second installation plate, the water inlet and water outlet can be installed through the two installation plates during use. Water enters the cooling water tank through the first installation plate and the hot water in the hot water tank is discharged through the second installation plate.

[0015] In one preferred embodiment, a turntable is rotatably connected to the fixed base plate, and the outer compartment is rotatably connected to the turntable.

[0016] The above technical solution involves a turntable, which makes the outer compartment rotate more smoothly during use.

[0017] In a preferred embodiment, a sealing plate is fixedly connected to the top of the heat exchange chamber on the side near the water pipe, and the water pipe is fixedly connected to the sealing plate on the heat exchange chamber.

[0018] The above technical solution involves installing a closed plate on the heat exchange chamber. During use, a filter plate can be inserted in the middle of the heat exchange chamber. This allows hot water to first enter the hot water chamber from the metal pipe into the water storage chamber, and then contact the fan blades on the rotating part through the water pipe. This causes the rotating part to rotate, and the water flows from the fixed ring to the other side of the heat exchange chamber away from the water pipe, colliding with the water that has just entered the heat exchange chamber. This results in a more uniform heat exchange and also prevents the water that has just entered the heat exchange chamber from flowing directly out of the filter screen installed on the heat exchange chamber.

[0019] In a preferred embodiment, a water outlet is provided on the side of the heat exchange chamber away from the water pipe.

[0020] The above technical solution is adopted so that the water outlet hole can facilitate the entry of hot water into the heat exchange chamber.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, after hot water enters the water storage tank through the metal pipe, it first enters the hot water tank and then contacts the rotating fan blades through the water pipe, causing the rotating component to rotate. This causes the water to flow from the fixed ring to the other side of the heat exchange tank and collide with the newly entered water, achieving uniform heat exchange. When the water flow is unstable, a filter screen is inserted in the heat exchange tank to prevent the water from flowing out before sufficient heat exchange, ensuring good heat exchange effect under different working conditions. There is no need to limit the direction of water flow through spring plates. A mechanical structure is used to replace the elastic positioning plate to achieve water flow control, which solves the drawbacks caused by the change in the performance of elastic materials in the prior art.

[0023] In this invention, a handheld device is provided to rotate the outer chamber by turning the handheld device, thereby controlling the timing and flow rate of hot water outflow. This enhances the adaptability and convenience of the equipment in practical applications. The structure and rotation design of the inner and outer chambers not only facilitate the rotation of the outer chamber, but also help improve the heat exchange effect by heating the air in the inner chamber.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-4 As shown, a semi-volumetric heat exchanger for improving heat exchange efficiency includes a fixed base plate 1, on which a flow guiding component 2 is provided.

[0034] The flow guiding assembly 2 includes an outer chamber 21, a cooling water tank 26 fixedly connected to the outer chamber 21, a water pump 23 fixedly connected to the cooling water tank 26, a delivery pipe 25 fixedly connected to the water pump 23, a metal pipe 24 fixedly connected to the end of the delivery pipe 25 away from the water pump 23, an inner chamber 22 fixedly connected to the metal pipe 24, a water storage tank 217 fixedly connected to the end of the metal pipe 24 away from the fixed base plate 1, a rotating component 214 rotatably connected inside the water storage tank 217, a fan blade fixedly connected to the rotating component 214, and a heat exchanger fixedly connected inside the water storage tank 217. The heat exchange chamber 215 is fixedly connected to a water pipe 216. The water storage chamber 217 is fixedly connected to a conical frame 211. A sealing bead 212 is slidably connected inside the conical frame 211. A sliding member 210 is slidably connected to the conical frame 211. A spring 29 is fixedly connected to the bottom of the sliding member 210. The spring 29 is fixedly connected to the outer chamber 21. A hot water chamber 28 is fixedly connected to the outer chamber 21. A second mounting plate 32 is provided on the hot water chamber 28. A fixing ring 213 is fixedly connected inside the water storage chamber 217. A filter screen is fixedly connected inside the heat exchange chamber 215.

[0035] A sealing plate is fixedly connected to the top of the heat exchange chamber 215 near the water pipe 216. The water pipe 216 is fixedly connected to the sealing plate on the heat exchange chamber 215. A water outlet is opened on the side of the heat exchange chamber 215 away from the water pipe 216. By setting a sealing plate on the heat exchange chamber 215, a filter plate can be inserted in the middle of the heat exchange chamber 215 during use. When hot water is input into the water storage chamber 217 from the metal pipe 24, it first enters the hot water chamber 28, and then contacts the fan blade on the rotating part 214 from the water pipe 216, causing the rotating part 214 to rotate. The water flows from the fixed ring 213 to the other side of the heat exchange chamber 215 away from the water pipe 216, colliding with the water that has just entered the heat exchange chamber 215. The heat exchange is more uniform, and it can also prevent the water that has just entered the heat exchange chamber 215 from flowing directly out of the filter screen installed on the heat exchange chamber 215 to a certain extent.

[0036] In this invention, after hot water enters the water storage tank 217 through the metal pipe 24, it first enters the hot water tank 28 and then contacts the fan blades of the rotating component 214 through the water pipe 216, causing the rotating component 214 to rotate. This causes the water to flow from the fixed ring 213 to the other side of the heat exchange tank 215 and collide with the newly entered water, achieving uniform heat exchange. When the water flow is unstable, a filter screen is inserted in the heat exchange tank 215 to prevent the water from flowing out before sufficient heat exchange, ensuring good heat exchange effect under different working conditions. There is no need to limit the direction of water flow through the spring sheet. The mechanical structure replaces the elastic positioning sheet to achieve water flow control, solving the drawbacks caused by the change in the performance of the elastic material in the prior art.

[0037] Furthermore, a handheld component 3 is fixedly connected to the water storage tank 217. The side of the handheld component 3 away from the water storage tank 217 is fixedly connected to the hot water tank 28. By providing the handheld component 3, the outer tank 21 can be rotated by external force when in use, so that the sliding component 210 contacts the sealing bead 212. Under the action of the spring 29, the sealing bead 212 is pushed out, so that hot water leaks out from the conical frame 211.

[0038] A water outlet is provided on the hot water tank 28, and a second mounting plate 32 is fixedly connected to the water outlet on the hot water tank 28. A water inlet is provided on the cooling water tank 26, and a first mounting plate 31 is fixedly connected to the water inlet on the cooling water tank 26. By providing the first mounting plate 31 and the second mounting plate 32, the water inlet and water outlet can be installed through the two mounting plates during use. Water enters the cooling water tank 26 through the first mounting plate 31, and the hot water in the hot water tank 28 is discharged through the second mounting plate 32.

[0039] The above solution also fails to address how hot water enters the hot water tank 28 from the storage tank 217 and then is discharged. Figure 1 , Figure 2 , Figure 4 As shown, the outer chamber 21 is rotatably connected to the fixed base plate 1, and the inner chamber 22 is fixedly connected to the fixed base plate 1. By setting the outer chamber 21 to be rotatably connected to the fixed base plate 1, it is convenient to rotate the outer chamber 21. A gap is left between the inner chamber 22 and the outer chamber 21. The high temperature of the inner chamber 22 will heat the air inside, making the heat exchange effect better.

[0040] A turntable 27 is rotatably connected to the fixed base plate 1, and the outer compartment 21 is rotatably connected to the turntable 27. By setting the turntable 27, the outer compartment 21 can rotate more smoothly during use.

[0041] Working principle: such as Figure 1 - Figure 4 As shown, when in use, a heater is installed in the inner chamber 22 according to the needs of different usage scenarios. Then, a water inlet pipe for cooling water is connected to the first mounting plate 31 to supply water to the cooling water chamber 26.

[0042] Then, the water pump 23 is started, so that the water in the cooling water tank 26 is transported to the metal pipe 24 through the liquid delivery pipe 25. At this time, the temperature in the inner tank 22 gradually rises, and the water in the metal pipe 24 is heated on the inner tank 22 and transported to the water storage tank 217.

[0043] Before use, when hot water is introduced into the water storage tank 217 through the metal pipe 24, it first enters the hot water tank 28, and then contacts the fan blades on the rotating part 214 through the water pipe 216, causing the rotating part 214 to rotate. The water flows from the fixed ring 213 to the other side of the heat exchange tank 215 away from the water pipe 216, colliding with the water that just entered the heat exchange tank 215, making the heat exchange more uniform. If the working time is short and the water flow is not stable enough, a filter screen can be inserted into the heat exchange tank 215, which can prevent the water that just entered the heat exchange tank 215 from flowing directly out of the side of the heat exchange tank 215 away from the water pipe 216 to a certain extent, so that it cannot pass through the water pipe 216. When the water supply time is long, the rotating part 214 rotates faster and faster, and the water flow becomes stronger and stronger, and it will gradually and stably pass through the water pipe 216.

[0044] After the water temperature in the water storage tank 217 gradually rises to the target temperature, a hot water outlet pipe is connected to the hot water tank 28. By turning the handpiece 3 with external force, the outer tank 21 rotates, causing the sliding piece 210 to push out the sealing bead 212 under the action of the spring 29, so that the hot water flows out from the conical frame 211 and into the hot water tank 28, thus allowing the hot water to flow out.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
