Description

[0001] The invention relates to the technical field of heat exchangers, in particular to a cold storage heat exchanger. Background Art

[0002] The cold storage heat exchanger is a regenerative heat exchanger in which the fluid flows periodically and alternately, and the cold and hot fluids exchange heat alternately with the cold storage medium in the heat exchanger. In the low-temperature cycle, it achieves the purpose of accumulating cold through heat exchange;

[0003] A general cold storage heat exchanger has a phase change cold storage material placed inside. It has the function of exchanging heat between the cold storage agent and the external environment. It is a closed container. When filling the cold storage material, it is necessary to avoid thermal expansion and contraction and leave enough space. The volume of the filled cold storage material is generally about 75% of the inner volume of the cold storage heat exchanger. However, due to its closed nature, it is impossible to intuitively view the filling progress when filling the filler.

[0018] 3. The present invention cross-winds the hot air pipe and the cold air pipe on the storage tube, so that the exchange surface between the hot air pipe and the cold air pipe and the storage tube is expanded, thereby improving the exchange efficiency. At the same time, because the hot air pipe and the cold air pipe are cross-winding with each other, the exchange surface between the hot air pipe and the cold air pipe is also expanded, thereby reducing the energy loss caused by the exchange process and avoiding energy waste.

[0030] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Please see attached Figure 1 -Attached Figure 8 The present invention discloses a cold storage heat exchanger, comprising a box body 1, a storage cylinder 2 is arranged at the middle side of the box body 1, a prompt mechanism is arranged at the left side of the storage cylinder 2, a balance mechanism is arranged at the middle part of the top side of the storage cylinder 2, a hot air pipe 3 is arranged at the outer wall of the storage cylinder 2, and hot air connection ports 4 are fixedly connected at both the front and rear ends of the hot air pipe 3, a cold air pipe 6 is arranged at the outer wall of the storage cylinder 2, and cold air connection ports 5 are fixedly connected at both the front and rear ends of the cold air pipe 6, and the hot air pipe 3 and the cold air pipe 6 are staggered;

[0033] In the first embodiment, the rear sides of the outer walls of the prompt ring 14, the prompt ring 2 16 and the prompt ring 3 18 are fixedly connected to the limit ring 19, and the prompt ring 14, the prompt ring 2 16 and the prompt ring 3 18 are provided with a plurality of splicing grooves 20 on the side close to the box body 1, and a plurality of prompt grooves 22 are provided in the middle of the left side of the box body 1, and a connecting frame 21 is fixedly connected to the middle of the left side of the box body 1, and the plurality of prompt grooves 22 are connected by the connecting frame 21, and the connecting frame 21 and the plurality of splicing grooves 20 are arranged correspondingly;

[0034] Specifically, the prompt ring three 18, the prompt ring two 16 and the prompt ring one 14 pass through the prompt groove 22 to the outside of the box body 1 in sequence. When the prompt ring one 14 moves to the outside of the box body 1 and is flush with the prompt ring three 18 and the prompt ring two 16, it means that the amount of filler in the storage tube 2 has reached 73% to 75% of the volume of the storage tube 2. At this time, filling should be stopped. When the prompt ring one 14 exceeds the prompt ring three 18 and the prompt ring two 16, it enters the warning value and the filler should be withdrawn until the prompt ring one 14 is flush with the prompt ring three 18 and the prompt ring two 16.

[0035] In the second embodiment, the balancing mechanism includes a fixed seat 23, the bottom side of the fixed seat 23 is fixedly connected to the top side of the storage cylinder 2, the left end of the top side of the fixed seat 23 is fixedly connected to the air inlet pipe 24, the right end of the top side of the fixed seat 23 is fixedly connected to the air outlet pipe 25, the left and right ends of the top side of the air inlet pipe 24 and the left and right ends of the bottom side of the air outlet pipe 25 are both provided with empty grooves 26, the inside of the empty grooves 26 is slidably connected with a movable plate 27, and a sphere 28 is fixedly connected between two adjacent movable plates 27, the top sides of the two movable plates 27 on the left and the bottom sides of the two movable plates 27 on the right are both fixedly connected with telescopic columns 29, and a spring 30 is arranged on the outside of the telescopic columns 29, and the top side of the air inlet pipe 24 and the bottom side of the air outlet pipe 25 are both provided with air vents 31, and the diameter of the sphere 28 is larger than the diameter of the air vents 31;

[0036] Specifically, by coordinating the air inlet pipe 24 and the air outlet pipe 25, when the pressure difference between the storage cylinder 2 and the outside atmosphere is large due to the hot and cold cycle, the corresponding sphere 28 can be pushed open to allow the internal and external gases to circulate and balance the internal and external pressures, thereby further avoiding damage to the cold storage heat exchanger caused by thermal expansion and contraction of the filler.

[0037] In the third embodiment, the length of the prompt ring 14 is greater than the lengths of the prompt ring 2 16 and the prompt ring 3 18, the diameter of the prompt ring 3 18 is greater than the diameter of the prompt ring 2 16, the diameter of the prompt ring 2 16 is greater than the diameter of the prompt ring 14, the diameter of the prompt ring 14 is greater than the diameter of the fixed column 12, the hot air connection port 4, the cold air connection port 5, one end of the air inlet pipe 24 and the air outlet pipe 25 all penetrate the outer side surface of the box body 1, and the movable plate 7 is fixedly connected to the outer side surface of the storage tube 2 with a rubber ring 8;

[0038] Specifically, the rubber ring 8 is used to maintain the sealing of the device, and the different lengths of the prompt ring 14, the prompt ring 2 16, and the prompt ring 3 18 facilitate the determination of the volume occupied by the filler in the storage tube 2.

[0039] Working principle:

[0040] First, the filling material is placed through the storage tube 2. When the filling material enters the storage tube 2, the movable disk 7 in the storage tube 2 will be squeezed to move outward, thereby driving the prompt ring 3 18 to move synchronously, and at the same time, the connecting rod 9 will be squeezed so that the connecting rod 9 enters the fixed column 12 and squeezes the reset spring 11. As the amount of filling material increases, the squeezing of the movable disk 7 will become heavier. In this process, the prompt ring 3 18, the prompt ring 2 16 and the prompt ring 1 14 will pass through the prompt groove 22 to the outside of the box body 1 in sequence. When the prompt ring 1 14 moves to the outside of the box body 1 and is flush with the prompt ring 3 18 and the prompt ring 2 16, it means that the amount of filling material in the storage tube 2 has reached 73% to 75% of the volume of the storage tube 2. At this time, the filling material should be stopped. When the prompt ring 1 14 exceeds the prompt ring 3 18 and the prompt ring 2 16, it enters the warning value and the filling material should be withdrawn until the prompt ring 1 14 is flush with the prompt ring 3 18 and the prompt ring 2 16.

[0041] After the filler is placed, different hot and cold gases are transported through the corresponding hot air pipe 3 and cold air pipe 6 according to the use requirements, so that heat exchange occurs between the filler and the hot air pipe 3 and the cold air pipe 6. By cross-winding the hot air pipe 3 and the cold air pipe 6 on the storage tube 2, the exchange surface between the hot air pipe 3 and the cold air pipe 6 and the storage tube 2 is expanded, thereby improving the exchange efficiency. At the same time, because the hot air pipe 3 and the cold air pipe 6 are interlaced and intertwined, the exchange surface between the hot air pipe 3 and the cold air pipe 6 is also expanded, thereby reducing the energy loss caused by the exchange process and avoiding energy waste.

[0042] During the heat exchange process, the filler will increase in volume after cooling from a liquid state to a solid state. At this time, the gas in the storage cylinder 2 is compressed and the pressure increases, which lifts the ball 28 in the outlet pipe 25 and squeezes the spring 30 at the same time, so that the ball 28 is separated from the vent hole 31. The gas in the storage cylinder 2 moves to the outside through the outlet pipe 25. At this time, the internal and external pressures are balanced. The ball 28 is reset under the action of the spring 30 and the vent hole 31 in the outlet pipe 25 is re-sealed. After the solid phase is heated and changed to a liquid state, the volume will shrink. At this time, the space at the top of the cold storage heat exchanger is expanded to create a vacuum. The external atmosphere lifts the ball 28 in the inlet pipe 24 and squeezes the spring 30 at the same time, pushing the ball 28 into the storage cylinder 2. At this time, the internal and external pressures are balanced. The ball 28 is reset under the action of the spring 30 and the vent hole 31 in the inlet pipe 24 is re-sealed. At this point, the entire workflow ends.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
