Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an environmentally friendly and energy-saving heat exchanger. Background Technology

[0002] A heat exchanger is a device used to transfer heat between two or more fluids (liquid, gas, or steam, etc.). Its basic principle is to use heat conduction, heat convection, and heat radiation (mainly heat conduction and heat convection in most heat exchangers) to transfer heat from a higher-temperature fluid to a lower-temperature fluid, thereby achieving the purposes of heating, cooling, condensation, evaporation, etc.

[0003] Staff often find that when using current environmentally friendly and energy-saving heat exchangers, the cooling pipes inside the heat exchanger absorb the heat entering the heat exchanger, but the absorbed heat cannot be reused, resulting in a waste of energy. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an environmentally friendly and energy-saving heat exchanger.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an environmentally friendly and energy-saving heat exchanger, comprising a shell and a cold water chamber, wherein an air outlet is fixedly connected to the shell, an air inlet is fixedly connected to the shell, a medium pipe is fixedly connected to the shell, a connecting pipe is fixedly connected to the output end of the medium pipe, a water collection tank is fixedly connected to one end of the connecting pipe, a circulating pump is fixedly connected to the water collection tank, the output end of the circulating pump is fixedly connected to the medium pipe, an energy-saving structure is provided on the water collection tank, the energy-saving structure mainly consists of a high-temperature chamber, the high-temperature chamber is opened on the water collection tank, a first liquid inlet pipe is fixedly connected to the high-temperature chamber, a second liquid inlet pipe is fixedly connected to the cold water chamber, both the first liquid inlet pipe and the second liquid inlet pipe are connected to the connecting pipe, and valves are provided on both the first liquid inlet pipe and the second liquid inlet pipe.

[0006] The aforementioned components achieve the following effects: high-temperature gas is introduced into the casing through the inlet, and then the circulation pump is started. The circulation pump pumps the low-temperature liquid in the water collection tank into the medium pipe. The high-temperature gas in the casing comes into contact with the low-temperature liquid in the medium pipe, achieving heat exchange. The gas after heat exchange is discharged to a designated location through the outlet, and the liquid after heat exchange flows to the water collection tank through the connecting pipe for recycling. Opening the valve on the first liquid inlet pipe allows hot water to be stored in the high-temperature chamber, enabling reuse of the hot water and preventing heat waste. Excess hot water enters the cold water chamber through the second liquid inlet pipe for cooling, and then circulates through the circulation pump. This avoids the situation where, in current heat exchangers, the cooling pipes inside the heat exchanger absorb the heat entering the heat exchanger, and the absorbed heat cannot be reused, resulting in energy waste.

[0007] Preferably, a plurality of insulation boards are fixedly connected to the inner wall of the high-temperature chamber, a hot water pipe is fixedly connected to the high-temperature chamber, and a valve is provided on the hot water pipe.

[0008] The above components achieve the following effects: the insulation board is made of polyurethane, which can keep the hot water in the high-temperature cavity warm and prevent a large amount of heat loss; and the hot water pipe is connected to the location where hot water is needed, making it more convenient to use.

[0009] Preferably, a number of heat dissipation fins are fixedly connected to the connecting pipe, and a number of heat dissipation holes are opened on the cold water chamber.

[0010] The effect achieved by the above components is that the heat dissipation fins and heat dissipation holes can increase the cooling speed of hot water flowing into the cold water chamber, thereby improving the heat exchange efficiency.

[0011] Preferably, the medium tube is provided with a high-efficiency structure, which is mainly composed of several heat-conducting plates. The heat-conducting plates are all disposed on the medium tube, and limiting blocks are fixedly connected to the heat-conducting plates. Several limiting grooves are opened on the medium tube, and two branch plates are fixedly connected to the heat-conducting plates.

[0012] The effect achieved by the above components is that by locking two limiting blocks in a limiting groove, several heat-conducting plates can be installed on the medium pipe. The heat-conducting plates and branch plates can increase the contact area with high-temperature gas, thereby improving the heat exchange effect.

[0013] Preferably, one of the heat-conducting plates has two connecting blocks fixedly connected to it, and the other heat-conducting plate has two connecting grooves.

[0014] The effect achieved by the above components is that by inserting the two connecting blocks into the two connecting slots, the two heat-conducting plates can be connected together.

[0015] Preferably, the connecting block has a circular groove, and a circular rod is slidably inserted into the connecting groove.

[0016] The effect achieved by the above components is that the sliding rod can be locked into the circular groove, which can limit the connection block and make the connection more stable.

[0017] Preferably, a spring is fitted onto the round rod, one end of the spring is fixedly connected to the connecting rod, and the other end of the spring is fixedly connected to the heat-conducting plate.

[0018] The effect achieved by the above components is that when the round rod is stuck in the round groove, the spring is in a stretched state, so the spring's rebound force acts on the connecting rod, making the limit more stable.

[0019] Preferably, a connecting rod is fixedly connected to the round rod, a sliding rod is fixedly connected to the connecting rod, a rectangular groove is formed in the heat-conducting plate, and a cam is rotatably connected in the rectangular groove.

[0020] The effect achieved by the above components is that the operator can rotate the cam, causing the long-diameter end of the cam to push the two slide rods, thereby sliding the round rod out of the round groove.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting an energy-saving structure, high-temperature gas is introduced into the shell through the air inlet, and then the circulation pump is started. The circulation pump pumps the low-temperature liquid in the water collection tank to the medium pipe. The high-temperature gas in the shell comes into contact with the low-temperature liquid in the medium pipe, which can achieve heat exchange. The gas after heat exchange is sent to a designated location through the air outlet, and the liquid after heat exchange flows to the water collection tank for recycling through the connecting pipe. By opening the valve on the first liquid inlet pipe, hot water is stored in the high-temperature chamber and can be reused to prevent heat waste. Excess hot water enters the cold water chamber through the second liquid inlet pipe for cooling, and then is circulated by the circulation pump. This avoids the situation where the cooling pipe inside the heat exchanger absorbs the heat entering the heat exchanger during heat exchange, and the heat absorbed by the heat exchanger cannot be reused, resulting in energy waste.

[0028] Example 1, such as Figure 1 and Figure 2 As shown, an environmentally friendly and energy-saving heat exchanger includes a shell 1, an air outlet 2 and an air inlet 3 fixedly connected to the shell 1, a medium pipe 4 fixedly connected to the shell 1, a connecting pipe 7 fixedly connected to the output end of the medium pipe 4, a water collection tank 8 fixedly connected to one end of the connecting pipe 7, a circulation pump 9 fixedly connected to the water collection tank 8, and the output end of the circulation pump 9 fixedly connected to the medium pipe 4.

[0029] Reference Figure 3The water collection tank 8 is equipped with an energy-saving structure 5, which mainly consists of a high-temperature chamber 51. The high-temperature chamber 51 is located on the water collection tank 8 and is fixedly connected to a first liquid inlet pipe 53. A second liquid inlet pipe 54 is fixedly connected to a cold water chamber 52. Both the first liquid inlet pipe 53 and the second liquid inlet pipe 54 are connected to a connecting pipe 7. Valves are installed on both the first liquid inlet pipe 53 and the second liquid inlet pipe 54. High-temperature gas is introduced into the shell 1 through the air inlet 3, and then the circulation pump 9 is started. The circulation pump 9 pumps the low-temperature liquid in the water collection tank 8 into the medium pipe 4. The high-temperature gas in the shell 1 comes into contact with the low-temperature liquid in the medium pipe 4, which can achieve heat exchange. The gas after heat exchange is discharged to a designated location through the air outlet 2, and the liquid after heat exchange flows to the water collection tank 8 through the connecting pipe 7 for recycling. By opening the valve on the first liquid inlet pipe 53, hot water is stored in the high-temperature chamber 51, which can be reused to prevent heat waste and excess water. Hot water enters the cold water chamber 52 through the second inlet pipe 54 for cooling, and then circulates through the circulation pump 9. This avoids the situation where the refrigeration pipe inside the heat exchanger absorbs the heat entering the heat exchanger during heat exchange, and the absorbed heat cannot be reused, resulting in wasted energy. Several insulation plates 55 are fixedly connected to the inner wall of the high-temperature chamber 51, and a hot water pipe 58 is fixedly connected to the high-temperature chamber 51. A valve is installed on the hot water pipe 58. The insulation plates 55 are made of polyurethane, which can keep the hot water in the high-temperature chamber 51 warm and prevent a large amount of heat loss. The hot water pipe 58 is connected to the location where hot water is needed, making it more convenient to use. Several heat dissipation fins 56 are fixedly connected to the connecting pipe 7, and several heat dissipation holes 57 are opened on the cold water chamber 52. The heat dissipation fins 56 and heat dissipation holes 57 can increase the cooling speed of the hot water flowing into the cold water chamber 52, thereby improving the heat exchange efficiency.

[0030] Reference Figure 2 , Figure 4 and Figure 5A high-efficiency structure 6 is provided on the medium pipe 4. The high-efficiency structure 6 is mainly composed of several heat-conducting plates 61. The heat-conducting plates 61 are all set on the medium pipe 4. Limiting blocks 64 are fixedly connected to the heat-conducting plates 61. Several limiting grooves 63 are opened on the medium pipe 4. Two branch plates 62 are fixedly connected to the heat-conducting plates 61. The two limiting blocks 64 are locked in one limiting groove 63, so that the heat-conducting plates 61 can be installed on the medium pipe 4. The heat-conducting plates 61 and the branch plates 62 can increase the contact area with the high-temperature gas, thereby improving the heat exchange effect. Two connecting blocks 65 are fixedly connected to one heat-conducting plate 61, and two connecting grooves 66 are opened on the other heat-conducting plate 61. The two connecting blocks 65 are locked into the two connecting grooves 66, so that the two heat-conducting plates 61 can be connected together. The connecting blocks 65 are provided with circular grooves 67, and the connecting grooves 66 slide upwards. A circular rod 68 is inserted. The sliding circular rod 68 is inserted into the circular groove 67 to limit the connection block 65, making the connection more stable. A spring 610 is sleeved on the circular rod 68. One end of the spring 610 is fixedly connected to the connecting rod 69, and the other end of the spring 610 is fixedly connected to the heat-conducting plate 61. When the circular rod 68 is inserted into the circular groove 67, the spring 610 is in a stretched state. Therefore, the rebound force of the spring 610 acts on the connecting rod 69, making the limit more stable. The connecting rod 69 is fixedly connected to the circular rod 68, and a sliding rod 612 is fixedly connected to the connecting rod 69. A rectangular groove 611 is opened in the heat-conducting plate 61. A cam 613 is rotatably connected in the rectangular groove 611. The operator can rotate the cam 613 so that the long diameter end of the cam 613 pushes the two sliding rods 612, thereby sliding the circular rod 68 out of the circular groove 67.

[0031] Working principle: High-temperature gas is introduced into the shell 1 through the air inlet 3, and then the circulation pump 9 is started. The circulation pump 9 pumps the low-temperature liquid in the water collection tank 8 to the medium pipe 4. The high-temperature gas in the shell 1 comes into contact with the low-temperature liquid in the medium pipe 4, achieving heat exchange. The gas after heat exchange is discharged to a designated location through the air outlet 2, and the liquid after heat exchange flows to the water collection tank 8 through the connecting pipe 7 for recycling. Opening the valve on the first liquid inlet pipe 53 allows hot water to be stored in the high-temperature chamber 51, enabling reuse of the hot water and preventing heat waste. Excess hot water enters the cold water chamber 52 through the second liquid inlet pipe 54 for cooling, and then circulates through the circulation pump 9. This avoids the situation where the cooling pipes inside the heat exchanger absorb the heat entering the heat exchanger during heat exchange, and the absorbed heat cannot be reused, resulting in energy waste. The insulation board 55 is a polyurethane board, which can insulate the hot water in the high-temperature chamber 51 to prevent heat loss. A large amount of heat is lost. Connecting the hot water pipe 58 to the location where hot water is needed makes it more convenient to use. The heat dissipation fins 56 and heat dissipation holes 57 can increase the cooling speed of the hot water flowing into the cold water chamber 52, thereby improving the heat exchange efficiency. By locking the two limiting blocks 64 into a limiting groove 63, several heat-conducting plates 61 can be installed on the medium pipe 4. The heat-conducting plates 61 and the branch plates 62 can increase the contact area with high-temperature gas, thereby improving the heat exchange effect. The two connecting blocks 65 are inserted into the two connecting... In groove 66, two heat-conducting plates 61 can be connected together. Sliding rod 68 can be inserted into groove 67 to limit the connection block 65, making the connection more stable. When rod 68 is inserted into groove 67, spring 610 is in a stretched state. Therefore, the rebound force of spring 610 acts on connecting rod 69, making the limit more stable. The operator can rotate cam 613, so that the long diameter end of cam 613 pushes two sliding rods 612, thereby sliding rod 68 out of groove 67.
