Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a high-efficiency and energy-saving heat exchanger. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. Heat exchangers are widely used in petroleum, chemical, metallurgical, power, shipbuilding, district heating, refrigeration and air conditioning and other fields.

[0003] Existing heat exchangers, such as the high-efficiency energy-saving heat exchanger described in Chinese Patent Application No. 202122408620.7, use segmented heat exchange to ensure a large temperature difference between liquids and improve heat exchange efficiency. However, this approach has drawbacks. It can only ensure rapid cooling of chemical raw materials. In order to maintain a large temperature difference, the multi-segment cooling tubes require more water. Since each segment's heat exchange is independent, the water temperature in each segment is not high after heat exchange, making it difficult to utilize. It can only play a basic heat exchange and cooling role, while the heat is not utilized, which is a waste. Therefore, a high-efficiency energy-saving heat exchanger is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency and energy-saving heat exchanger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency energy-saving heat exchanger, comprising a heat exchange chamber, wherein a heat exchange mechanism is provided inside the heat exchange chamber, the heat exchange mechanism comprising a refrigerant inlet pipe, a refrigerant outlet pipe, a heat exchanger inlet pipe, a distribution chamber, a heat exchanger outlet pipe, a collection chamber, and heat exchange tubes. A refrigerant inlet pipe is fixedly provided on one side of the heat exchange chamber, a refrigerant outlet pipe is fixedly provided on the side of the heat exchange chamber away from the refrigerant inlet pipe, a heat exchanger inlet pipe is provided on one side of the heat exchange chamber, a distribution chamber is fixedly provided at the lower end of the heat exchanger inlet pipe, a heat exchanger outlet pipe is provided on one side of the heat exchanger inlet pipe, a collection chamber is fixedly provided at the lower end of the heat exchanger outlet pipe, and a heat exchange tube is fixedly provided between the collection chamber and the distribution chamber. Multiple heat exchange tubes are provided and are arranged meanderingly inside the heat exchange chamber.

[0006] Preferably, the collecting chamber is equipped with a control mechanism for controlling the flow rate of the heat medium. The control mechanism includes a heated pipe, a piston, a connecting rod, a blocking rod, and a spring. A heated pipe is fixedly installed on one side of the collecting chamber. A piston is movably engaged inside the heated pipe. A connecting rod is fixedly installed at one end of the piston. A blocking rod is fixedly installed at one end of the connecting rod. A spring is sleeved on the outer surface of the connecting rod between the blocking rod and the heated pipe. One end of the spring is fixedly connected to the blocking rod, and the end of the spring away from the blocking rod is fixedly connected to the shell of the heated pipe. The control mechanism of this device can be understood as acting as a valve. The larger the opening, the greater the flow rate inside the heat medium inlet pipe, and the more heat medium flows through the heat exchanger tube per unit time, and vice versa. Thus, the flow opening of the heat medium inlet pipe can be automatically and quickly adjusted according to the heat of the heat medium inside the collecting chamber, reducing unnecessary heat waste. The spring can drive the blocking rod to automatically reset, so that when the temperature inside the collecting chamber changes, the blocking rod can be reset to expand the opening of the heat medium outlet pipe.

[0007] Preferably, the heat exchange tube is filled with a thermosensitive liquid. This thermosensitive liquid can be any liquid that expands easily when heated, such as mercury. The higher the temperature of the heat medium after heat exchange inside the collection chamber, the greater the expansion of this liquid will be. This will push the obstruction rod to insert deeper into the heat medium inlet pipe, thus reducing the opening of the heat medium inlet pipe and increasing the obstruction. This reduces the flow rate, allowing less heat medium to flow out of the heat exchange tube per unit time. This gives the heat medium more time to exchange heat inside the heat exchange tube, thus preventing insufficient heat exchange and heat waste.

[0008] Preferably, a heat-conducting plate is fixedly installed on the surface of the heat exchange tube inside the heat exchange chamber. The heat-conducting plate can increase the contact area between the heat exchange plate and the refrigerant inside the heat exchange chamber, thereby improving the heat exchange effect.

[0009] Preferably, the surface of the heat-conducting plate is provided with through grooves, which facilitate the flow of refrigerant inside the heat exchange chamber. The flow direction of the refrigerant can be as follows: Figure 4 As shown, the refrigerant enters the heat exchange chamber through the refrigerant inlet pipe on the left, then passes through multiple heat conduction plates and is discharged from the refrigerant outlet pipe on the right, thus enabling sufficient heat exchange.

[0010] Preferably, a mounting base is fixedly provided on the lower surface of the heat exchange chamber, which allows the entire device to be easily fixedly installed at the target location.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the heat medium is diverted and then reassembled to ensure sufficient contact area between the heat medium and the cold medium, thereby improving the heat exchange effect and allowing heat exchange to be carried out. This makes full use of the heat source and allows the water temperature to be higher. The higher temperature water is easier to use, such as for washing and heating, thus reducing the risk of heat waste.

[0013] 2. The higher the temperature of the heat medium after heat exchange inside the collection chamber of this utility model, the greater the expansion of the heat-sensitive liquid inside the heating pipe. This pushes the obstruction rod to insert deeper into the heat medium inlet pipe, thus reducing the opening of the heat medium inlet pipe and increasing the obstruction. This reduces the flow rate, allowing less heat medium to flow out of the heat exchange pipe per unit time. This gives the heat medium more time to exchange heat inside the heat exchange pipe, preventing insufficient heat exchange and heat waste. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency energy-saving heat exchanger, including a heat exchange chamber 1. The heat exchange chamber 1 is equipped with a heat exchange mechanism, which includes a refrigerant inlet pipe 2, a refrigerant outlet pipe 3, a heat medium inlet pipe 4, a distribution chamber 5, a heat medium outlet pipe 6, a collection chamber 7, and heat exchange pipes 8. The refrigerant inlet pipe 2 is fixedly installed on one side of the heat exchange chamber 1, and the refrigerant outlet pipe 3 is fixedly installed on the side of the heat exchange chamber 1 away from the refrigerant inlet pipe 2. The heat medium inlet pipe 4 is installed on the upper side of the heat exchange chamber 1, and the distribution chamber 5 is fixedly installed at the lower end of the heat medium inlet pipe 4. The heat medium outlet pipe 6 is installed on one side of the heat medium inlet pipe 4, and the collection chamber 7 is fixedly installed at the lower end of the heat medium outlet pipe 6. A heat exchange pipe 8 is fixedly installed between the collection chamber 7 and the distribution chamber 5. Multiple heat exchange pipes 8 are provided and are completely meandering inside the heat exchange chamber 1.

[0022] The collecting chamber 7 is equipped with a control mechanism for controlling the flow of the heat medium. The control mechanism includes a heating pipe 9, a piston 10, a connecting rod 11, a blocking rod 12, and a spring 13. A heating pipe 9 is fixedly installed on one side of the collecting chamber 7. A piston 10 is movably engaged inside the heating pipe 9. A connecting rod 11 is fixedly installed at one end of the piston 10, and a blocking rod 12 is fixedly installed at one end of the connecting rod 11. A spring 13 is sleeved on the outer surface of the connecting rod between the blocking rod 12 and the heating pipe 9. One end of the spring 13 is fixedly connected to the blocking rod 12. 3. The end away from the obstruction rod 12 is fixedly connected to the shell of the heat exchange tube 9. The control mechanism of this device can be understood as the function of a valve. The larger its opening, the greater the flow rate inside the heat medium inlet pipe 4, and the more heat medium flows through the heat exchange tube 8 per unit time. Conversely, the smaller the opening, the greater the flow rate inside the heat medium inlet pipe 4. Thus, the flow opening of the heat medium inlet pipe 4 can be automatically and quickly adjusted according to the heat of the heat medium inside the collection chamber 7, reducing unnecessary heat waste. The spring 13 can drive the obstruction rod 12 to have an automatic reset tendency. In this way, when the temperature inside the collection chamber 7 is at an angle, the obstruction rod 12 can be reset to expand the opening of the heat medium outlet pipe 6.

[0023] The heat exchange tube 9 is filled with a thermosensitive liquid, which can be any liquid that expands easily when heated, such as mercury. The higher the temperature of the heat medium after heat exchange in the collection chamber 7, the greater the expansion of this liquid will be. This will push the obstruction rod 12 to be inserted deeper into the heat medium inlet pipe 4, thus reducing the opening of the heat medium inlet pipe 4 and increasing the obstruction. This reduces the flow rate, allowing less heat medium to flow out of the heat exchange tube 8 per unit time. This gives the heat medium more time to exchange heat inside the heat exchange tube 8, thus preventing the heat medium from not being fully exchanged and wasting heat.

[0024] A heat-conducting plate 14 is fixedly installed on the surface of the heat exchange tube 8 inside the heat exchange chamber 1. The heat-conducting plate 14 can increase the contact area between the heat exchange plate and the refrigerant inside the heat exchange chamber 1, thereby improving the heat exchange effect.

[0025] The heat-conducting plate 14 has a through groove 15 on its surface, which facilitates the flow of refrigerant inside the heat exchange chamber 1. The flow direction of the refrigerant can be as follows: Figure 4 As shown, the refrigerant enters the heat exchange chamber 1 through the refrigerant inlet pipe 2 on the left, then passes through multiple heat conduction plates 14 and is discharged from the refrigerant outlet pipe 3 on the right, at which point heat exchange can be fully carried out.

[0026] A mounting base 16 is fixedly provided on the lower surface of the heat exchange chamber 1, which allows the entire device to be easily fixedly installed at the target position.

[0027] Working principle: When using this device, the refrigerant flows in the following direction, such as... Figure 4 As shown, the refrigerant enters the heat exchange chamber 1 through the left-side refrigerant inlet pipe 2, then passes through multiple heat-conducting plates 14 and exits through the right-side refrigerant outlet pipe 3, thus facilitating heat exchange. Meanwhile, the hot medium flows into the distribution chamber 5 through the hot medium inlet pipe, then enters the heat exchange chamber 1 through multiple heat exchange pipes 8. After fully contacting the refrigerant inside the heat exchange chamber 1, it enters the return chamber and exits through the hot medium outlet pipe 6. In this way, the hot medium is distributed and then reassembled, ensuring sufficient contact area between the hot and cold medium to improve the heat exchange effect and fully utilize the heat source. This allows for higher water temperatures, which are more readily available for use, such as for washing and heating, thus minimizing heat waste.

[0028] Meanwhile, when this device is in use, the higher the temperature of the heat medium after heat exchange inside the collection chamber 7, the greater the expansion of the heat-sensitive liquid inside the heating pipe 9 will be. This will push the obstruction rod 12 to insert deeper into the heat medium inlet pipe 4, thus reducing the opening of the heat medium inlet pipe 4 and increasing the obstruction. This will reduce the flow rate, allowing less heat medium to flow out of the heat exchange pipe 8 per unit time. This will give the heat medium more time to exchange heat inside the heat exchange pipe 8, thus preventing the heat medium from not being fully exchanged and thus avoiding heat waste.

[0029] It should be noted that the lower end of the heating tube 9 of this device is thicker and the end of the piston 10 is thinner. This makes the device more sensitive to thermal expansion. Because the end of the piston 10 is thinner, a slight change in temperature and a slight expansion of the thermosensitive liquid can more easily push the piston 10 to move inside the heating tube 9.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
