Description
Technical Field
[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger with a bypass pipe. Background Art
[0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid, also known as heat exchanger. Heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler, etc., and is widely used. Existing heat exchangers have unreasonable heat exchange area design, resulting in small heat exchange area, short water flow, low heat exchange efficiency, and most of them do not have the function of minimum water flow circulation for heating return water, which makes the heat exchanger easy to damage.
[0003] In order to solve the above problems, the utility model patent with publication number CN219284028U discloses a heat exchanger with a bypass pipe. In this scheme, a box is set up, an opening is formed at one end of the box, a heat exchange chamber is set at the bottom away from the opening, a water collection chamber is formed in the box, a plurality of parallel and spaced fins are set in the heat exchange chamber, a water-passing part is set close to the plate outside the box, the water-passing part includes a heat exchange part, the heat exchange part penetrates the heat exchange chamber through the fins, and passes out of the box to form a water inlet pipe and a water outlet pipe at both ends, and the water-passing part also includes a body pipe, which is connected between the water inlet pipe and the water outlet pipe, and the body pipe is coiled and close to the outside of the box, and the body pipe and the water inlet pipe are connected through the bypass pipe. Local overheating of the heat exchanger will cause local material annealing. The bypass pipe is used to ensure that the minimum safe flow flows through the heat exchanger with the minimum water flow of the constant heating system, which protects the heat exchanger itself.
[0004] However, there are still some shortcomings in the above scheme. In the above scheme, the heat exchanger is protected by the barrel transport pipe to avoid the safety hazard caused by local overheating of the heat exchanger. However, the barrel transport pipe in the above scheme is an integrated structure. When the barrel transport pipe is partially damaged after long-term use, the barrel transport pipe needs to be disassembled as a whole, resulting in waste of the barrel transport pipe part that can be used normally, and additionally increasing the maintenance cost. In view of this, we propose a heat exchanger with a bypass pipe. Utility Model Content

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Example 1
[0027] A heat exchanger with a bypass pipe, such as Figure 1-Figure 5As shown, it includes a box body 1; a heat exchange mechanism 2 is arranged in the middle of the box body 1, and the heat exchange mechanism 2 includes a heat exchanger body 201, the heat exchanger body 201 is fixedly connected to the middle of the box body 1, the outside of the heat exchanger body 201 is connected to a heat exchange tube 202, the heat exchange tube 202 is movably connected to the outside of the box body 1, and bypass pipes 203 are connected to both sides of the box body 1, and the two ends of the heat exchange tube 202 are respectively connected to the bypass pipe 203. The heat exchange mechanism 2 can perform protective operations on the heat exchanger body 201 to avoid the safety hazard caused by local overheating of the heat exchanger body 201, and at the same time, the heat exchange tube 202 is wrapped around the heat exchanger body 201. The bypass pipe 203 is arranged on the outside of the heat exchanger body 201, and the heat exchanger body 201 can be uniformly protected. The top of the box body 1 is fixedly connected to the water inlet pipe 3, and the bottom of the box body 1 is connected to the drain pipe 4. The two bypass pipes 203 are respectively connected to the water inlet pipe 3 and the drain pipe 4. The side of the box body 1 is fixedly connected to the support plate 5, and the bypass pipe 203 is fixedly connected to the top of the support. The support plate 5 structure can support and fix the bypass pipe 203, thereby ensuring the stability of the position support plate 5. The heat exchange tube 202 is fixedly connected to the baffle plate 204, and the baffle plate 204 is staggeredly arranged on the heat exchange tube 202. The ends of the baffle plates 204 are arranged to be inclined in the direction of the water flow on the inner walls of both sides. The baffle plates 204 arranged in an interlaced manner inside the heat exchange tubes 202 can delay the water flow, so that the water flow can fully contact the heat exchanger body 201. When the water flow hits the baffle plates 204 with an inclined structure, part of the water flow flows along the baffle plates 204 with an inclined structure and forms a reflux in the opposite direction of the water flow when it hits the baffle plates 204 and the walls of the heat exchange tubes 202. The reflux can delay the flow rate of the water flow when it hits the water flow, thereby achieving the effect of reducing the flow rate of the water flow. The side of the bypass pipe 203 is connected with a guide The flow pipe 205, the heat exchange pipe 202 and the guide pipe 205 are interconnected, and the guide pipe 205 is respectively connected with a one-way valve 206 and a control valve 207. The guide pipe 205 structure can connect the heat exchange pipe 202 with the bypass pipe 203, so that the heat exchange pipe 202 can be easily disassembled from the bypass pipe 203. At the same time, the one-way valve 206 is arranged at the water outlet end of the heat exchange pipe 202, and the control valve 207 is connected to the water inlet end of the heat exchange pipe 202. When the heat exchange pipe 202 is disassembled, the bypass pipe 203 can be closed by the one-way valve 206 and the control valve 207 structure.
[0028] Example 2
[0029] like Figure 1-Figure 4As shown, the box body 1 is provided with a mounting mechanism 6, and the mounting mechanism 6 includes a mounting plate 601, and the mounting plate 601 is movably connected to the bottom end of the box body 1. A card slot 602 is provided on the mounting plate 601, and a card block 603 corresponding to the card slot 602 structure is connected to the bottom end of the box body 1. The mounting mechanism 6 can perform synchronous installation operations on the bypass pipe 203 and the heat exchange pipe 202. The card block 603 is a hook-shaped structure, and the card block 603 can be conveniently bent inward. The mounting plate 601 can be fixed to the bottom end of the box body 1 in conjunction with the card slot 602. A positioning groove 604 is provided on the top end of the mounting plate 601, and the positioning groove 604 is inclined inwardly. The bottom end of the support plate 5 is an arc-shaped structure, and the support plate 5 is abutted against the movable plate. It is configured that both ends of the heat exchange tube 202 are fixedly connected with sealing rings 605, and the inwardly inclined positioning grooves 604 can squeeze the support plate 5 and the bypass pipe 203 inward during the installation of the mounting plate 601, thereby compressing the sealing rings 605 at both ends of the heat exchange tube 202 to prevent water from leaking outward from the gap between the heat exchange tube 202 and the guide tube. Support frames 606 are hinged on both sides of the box body 1, and support grooves 607 corresponding to the structure of the support frame 606 are opened on the side of the box body 1. The support frame 606 is arranged inside the support groove 607. The support frame 606 can support the heat exchange tube 202 so that the heat exchange tube 202 can be kept on the outside of the box body 1 during the installation of the mounting plate 601.
[0030] When the heat exchanger with a bypass pipe of the utility model is in use, the hot water flow enters the bypass pipe 203 from the water inlet pipe 3 and flows along the heat exchange pipe 202. The baffle plate 204 inside the heat exchange pipe 202 causes the water flow to form multiple refluxes and slows down the water flow rate, so that the hot water flow inside the heat exchange pipe 202 is fully in contact with the heat exchanger body 201, thereby improving the heat exchange time. When a single heat exchange pipe 202 has an abnormality and needs to be replaced, the block 603 is taken out from the slot 602, and the mounting plate 601 can be conveniently removed from the bottom of the box body 1. At the same time, the bypass pipe 203 is tilted to both sides, and the heat exchange pipe 202 can be removed from the box body 1 in turn. After the heat exchange pipe 202 is replaced, the heat exchange pipe 202 can be reinstalled to the outside of the box body 1, and the support frames 6 on both sides of the box body 1 are 06 can support the heat exchange tube 202, and the hinged support frame 606 can be rotated and stored in the support groove 607 to facilitate the movement of the heat exchange tube 202. After the heat exchange tube 202 is supported by the support frame 606, the bypass pipe 203 is rotated inwardly to connect the two ends of the heat exchange tube 202 with the backflow pipe, and at the same time, the mounting plate 601 is moved toward the direction of the box body 1. The positioning groove 604 on the mounting plate 601 drives the support plate 5 to deflect inwardly until the sealing ring 605 at both ends of the heat exchange tube 202 is compressed to avoid leakage at the connection. When the support plate 5 moves to the bottom of the positioning groove 604, the bypass pipe 203 and the drain pipe 4 contact each other and move to the inside of the drain 4. At the same time, when the mounting plate 601 is installed, the hook-shaped structure block 603 immediately fixes the mounting plate 601.
