Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical technology, and in particular to a heat exchange tank. Background Technology

[0002] In pharmaceutical manufacturing, many containers have stringent temperature requirements. Often, the same equipment must be able to both heat and cool to meet external environmental and production demands. Some containers with even higher requirements need to be used alternately under both heating and cooling conditions. For larger containers, heat transfer methods include: integral jackets, half-tube jackets, internal coils, and honeycomb jackets. Internal coils, located inside the container, are difficult to maintain; honeycomb jackets are unsuitable for high-temperature conditions and are expensive. Therefore, in pharmaceutical manufacturing, half-tube jackets on the outer wall of the container are more commonly used for heating.

[0003] In a single-half-tube jacket, either a cold or hot medium can be injected to cool or heat the container. However, when alternating hot and cold cycles are required, a single-cavity half-tube jacket necessitates a more complex piping structure to accommodate both media. Furthermore, the first medium must be purged before injecting the second; otherwise, temperature control within the container will be interrupted. Moreover, because both media operate within the same cavity, complete purging is often impossible, and careful consideration must be given to the potential chemical reactions between the two media that could affect pharmaceutical production.

[0004] Utility model patent application CN 209588763 U discloses a heat exchange tank, comprising a container body, a refrigerant circulation outer half-pipe, and a heat medium circulation outer half-pipe. The refrigerant circulation outer half-pipe and the heat medium circulation outer half-pipe are mounted on the container body in a double helix shape. The refrigerant circulation outer half-pipe has a refrigerant inlet and a refrigerant outlet, and the heat medium circulation outer half-pipe has a heat medium inlet and a heat medium outlet. However, there is a gap between the refrigerant circulation outer half-pipe and the heat medium circulation outer half-pipe in the above-mentioned heat exchange tank, resulting in a waste of the tank's heat exchange area. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a heat exchange tank that increases the heat exchange area of ​​the tank and prevents cracks from forming at the connection between the coil and the tank caused by alternating flow of refrigerant and hot medium into the same coil.

[0006] To achieve the above objectives, this utility model provides a heat exchange tank, including a tank body, a first coil, and a second coil;

[0007] The first coil and the second coil are both coiled around the outer wall of the tank, with the first coil and the second coil spaced apart, and one side of the second coil resting on the first coil.

[0008] In this invention, the second coil is mounted on one side of the first coil, which makes full use of the heat exchange area of ​​the tank and can effectively reduce energy consumption.

[0009] In this invention, the first and second coils are spirally wound together according to the size of the tank. The first and second coils are spaced apart to form a "refrigerant and heat medium separate inlet and outlet" mode, allowing the refrigerant and heat medium to flow separately through the first and second coils. This avoids cracks at the connection between the coil and the tank caused by alternating flow of refrigerant and heat medium into the same coil, ensuring stable temperature control. It also prevents refrigerant or heat medium residue from remaining in the same coil, avoids chemical reactions between the refrigerant and heat medium, and allows for a wider range of refrigerant and heat medium options.

[0010] Optionally, the first coil is used to transport heat medium, and the second coil is used to transport refrigerant.

[0011] The heat exchange area between the first coil and the tank is larger than that between the second coil and the tank. When the demand for heat medium is greater, the first coil can be used to transport heat medium and the second coil can be used to transport refrigerant.

[0012] Optionally, the first coil is used to transport refrigerant, and the second coil is used to transport heat medium.

[0013] The heat exchange area between the first coil and the tank is larger than that between the second coil and the tank. When the refrigerant demand is greater, the first coil can be used to transport the refrigerant and the second coil can be used to transport the heat medium.

[0014] Optionally, both the first coil and the second coil have arc-shaped cross-sections to ensure that the first coil is tightly connected to the tank, and that one side of the second coil is tightly connected to the tank and the other side is tightly connected to the first coil.

[0015] Optionally, the first coil is welded to the outer wall of the tank, and the second coil is welded to the outer wall of the tank on one side and to the first coil on the other side.

[0016] The first and second coils form a "refrigerant and heat medium separate inlet and outlet" mode, allowing the refrigerant and heat medium to flow separately through the first and second coils, which can prevent the refrigerant and heat medium from being alternately introduced into the same coil, thus avoiding weld cracks.

[0017] Optionally, the first coil is provided with a first inlet and a first outlet, the first inlet being located at the upper part of the first coil and the first outlet being located at the lower part of the first coil.

[0018] Optionally, the second coil is provided with a second inlet and a second outlet, with the second inlet located at the upper part of the second coil and the second outlet located at the lower part of the second coil.

[0019] Beneficial effects:

[0020] This utility model includes a tank, a first coil, and a second coil; the second coil is mounted on the first coil on one side, so that the heat exchange area of ​​the tank is fully utilized and energy consumption can be effectively reduced.

[0021] In this invention, the first and second coils are spirally wound together according to the size of the tank. The first and second coils are spaced apart to form a "refrigerant and heat medium separate inlet and outlet" mode, allowing the refrigerant and heat medium to flow separately through the first and second coils. This avoids cracks at the connection between the coil and the tank caused by alternating flow of refrigerant and heat medium into the same coil, ensuring stable temperature control. It also prevents refrigerant or heat medium residue from remaining in the same coil, avoids chemical reactions between the refrigerant and heat medium, and allows for a wider range of refrigerant and heat medium options.

[0031] The first coil 2 and the second coil 5 are both coiled around the outer wall of the tank 1. The first coil 2 and the second coil 5 are spaced apart, and one side of the second coil 5 is laid on the first coil 2.

[0032] Specifically, in this utility model, the second coil 5 is mounted on the first coil 2 on one side, so that the heat exchange area of ​​the tank 1 is fully utilized, which can effectively reduce energy consumption.

[0033] In this invention, the first coil 2 and the second coil 5 are spirally wound according to the size of the tank 1. The first coil 2 and the second coil 5 are spaced apart to form a "refrigerant and hot medium separate inlet and outlet" mode, allowing the refrigerant and hot medium to flow separately through the first coil 2 and the second coil 5. This avoids the refrigerant and hot medium alternating into the same coil, which could cause cracks at the connection between the coil and the tank 1, thus maintaining stable temperature control. It also avoids the refrigerant or hot medium residue caused by the refrigerant and hot medium flowing into the same coil, and prevents chemical reactions between the refrigerant and hot medium. The range of refrigerant and hot medium that can be selected is also wider.

[0034] See Figure 1 and 2 In some embodiments of this utility model, the first coil 2 is used to transport heat medium, and the second coil 5 is used to transport refrigerant.

[0035] In this embodiment, the heat exchange area between the first coil 2 and the tank 1 is greater than that between the second coil 5 and the tank 1. When the heat medium demand is greater, the first coil 2 can be used to transport the heat medium and the second coil 5 can be used to transport the refrigerant.

[0036] See Figure 1 and 2 In some embodiments of this utility model, the first coil 2 is used to transport refrigerant, and the second coil 5 is used to transport heat medium.

[0037] In this embodiment, the heat exchange area between the first coil 2 and the tank 1 is greater than that between the second coil 5 and the tank 1. When the refrigerant demand is greater, the first coil 2 can be used to transport the refrigerant and the second coil 5 can be used to transport the heat medium.

[0038] See Figure 1 and 2 In some embodiments of this utility model, the cross-sections of the first coil 2 and the second coil 5 are both arc-shaped to ensure that the first coil 2 is tightly connected to the tank 1, and to ensure that one side of the second coil 5 is tightly connected to the tank 1 and the other side is tightly connected to the first coil 2.

[0039] In this embodiment, the first coil 2 is a pipe with a semi-circular cross-section, and the second coil 5 is a pipe with an incomplete circular cross-section of the same diameter.

[0040] See Figure 1 and 2 In some embodiments of this utility model, the first coil 2 is welded to the outer wall of the tank 1, and the second coil 5 is welded to the outer wall of the tank 1 on one side and to the first coil 2 on the other side.

[0041] The first coil 2 and the second coil 5 form a "refrigerant and hot medium separate entry and exit" mode, allowing the refrigerant and hot medium to flow separately through the first coil 2 and the second coil 5, which can prevent the refrigerant and hot medium from being alternately introduced into the same coil, thus avoiding the formation of weld cracks.

[0042] See Figure 1 and 2 In some embodiments of this utility model, the first coil 2 is provided with a first inlet 3 and a first outlet 4, the first inlet 3 is located at the upper part of the first coil 2, and the first outlet 4 is located at the lower part of the first coil 2.
