Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, and in particular to a drip-proof cooling component. Background Technology

[0002] With advancements in technology, dispensing processes are now widely used in product manufacturing. Dispensing primarily consists of adhesive, dispensing equipment, and dispensing valves. Some adhesives used in dispensing tend to cure at room temperature, making dispensing difficult. Cooling devices are often used in these cases, but the low temperature and large temperature difference with the surrounding environment can cause condensation to form on the surface. This condensation dripping onto the product can damage or cause defects. Current cooling devices typically collect condensation to prevent dripping, or add insulation layers to the outside of the cooling components to delay condensation. However, these methods do not address the root cause of condensation problems within the cooling device itself. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a drip-proof cooling component, which can fundamentally solve the problem of condensation dripping from the cooling body and adjacent components during the dispensing process, which affects product quality.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a drip-proof cooling component, comprising: a cooling body that is in contact with the cooling surface of a cooling chip, a heat dissipation plate disposed on the side of the cooling chip opposite to the cooling body, the heat dissipation surface of the cooling chip being in contact with the heat dissipation plate, and a heat-conducting shell disposed on the outer side of the cooling body, the heat-conducting shell being in contact with the heat dissipation plate, thereby forming a heat insulation cavity between the inner wall of the heat-conducting shell, which is spaced apart from the cooling body, the cooling body, and the heat dissipation plate.

[0005] The following are further improvements to the above technical solution: 1. In the above scheme, the edges of the heat-conducting shell are in contact with the heat sink surface.

[0006] 2. In the above scheme, the refrigeration body and the heat-conducting shell are each fixedly installed on the heat dissipation plate by bolts, and the two side surfaces of the refrigeration chip located between the refrigeration body and the heat dissipation plate are in close contact with the refrigeration body and the heat dissipation plate respectively.

[0007] 3. In the above scheme, the cooling body is connected to the heat sink through mounting blocks respectively disposed on the upper and lower sides of the cooling chip.

[0008] 4. In the above scheme, the refrigeration body, the heat-conducting shell and the heat sink are all metal bodies with high thermal conductivity.

[0009] 5. In the above scheme, the refrigeration body is a copper refrigeration body, an aluminum refrigeration body, or a brass refrigeration body, the heat-conducting shell is a copper shell or an aluminum shell, and the heat sink is a copper plate or an aluminum plate.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model relates to a drip-proof cooling component. A heat sink is positioned on the side of the cooling element opposite to the cooling body, with the heat dissipation surface of the cooling element in contact with the heat sink. A heat-conducting shell is provided on the outer side of the cooling body, and this shell is in contact with the heat sink. This creates a heat-insulating cavity between the inner wall of the heat-conducting shell, spaced apart from the cooling body, the cooling body, and the heat sink. This transfers heat from the heat sink to the heat-conducting shell, improving the heat dissipation efficiency of the heat sink and saving energy. Furthermore, it reduces the temperature difference between the cooling body and the surrounding environment while maintaining cooling performance, and prevents the heat-conducting shell from being affected by the low temperature of the cooling body, thus avoiding a large temperature difference between the shell and the environment. This fundamentally solves the problem of condensation dripping from the cooling body and adjacent components during the dispensing process, which affects product quality. Attached Figure Description

Detailed Implementation

[0013] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0014] Example 1: A drip-proof cooling assembly includes: a cooling body 1 that is in contact with the cooling surface of a cooling chip 2; a heat sink 7 is disposed on the side of the cooling chip 2 opposite to the cooling body 1; the heat dissipation surface of the cooling chip 2 is in contact with the heat sink 7; a heat-conducting shell 3 is disposed on the outer side of the cooling body 1; the heat-conducting shell 3 is in contact with the heat sink 7; thereby, the inner wall of the heat-conducting shell 3, which is spaced apart from the cooling body 1, forms a heat insulation cavity 4 between the cooling body 1 and the heat sink 7.

[0015] The edges of the aforementioned heat-conducting housing 3 are in contact with the surface of the heat sink 7; the aforementioned refrigeration body 1 and heat-conducting housing 3 are each fixedly installed on the heat sink 7 by bolts, and the two side surfaces of the refrigeration chip 2 located between the refrigeration body 1 and the heat sink 7 are in close contact with the refrigeration body 1 and the heat sink 7 respectively.

[0016] The aforementioned refrigeration body 1 is connected to the heat sink 7 via mounting blocks 5 respectively disposed on the upper and lower sides of the refrigeration chip 2; the aforementioned refrigeration body 1, heat-conducting shell 3 and heat sink 7 are all metal bodies with high thermal conductivity.

[0017] The aforementioned refrigeration body 1 is a copper refrigeration body, the heat-conducting shell 3 is a copper shell, and the heat dissipation plate 7 is a copper plate; the aforementioned heat dissipation plate 7 has an installation groove 71 for embedding the refrigeration chip 2.

[0018] At least one temperature sensor 8 is embedded in the aforementioned refrigeration body 1, which can acquire the temperature of the refrigeration body in real time and control and adjust it as needed to maintain the stability of the refrigeration temperature. The specific control and adjustment methods can be adopted using existing technologies, and will not be elaborated here.

[0019] The aforementioned refrigeration body 1 has at least one receiving groove 6 for embedding a mixing tube 100 and a dispensing head 200, and the heat-conducting housing 3 has a clearance through hole 31 for the mixing tube 100 and the dispensing head 200 to pass through.

[0020] Example 2: A drip-proof cooling assembly includes: a cooling body 1 that is in contact with the cooling surface of a cooling chip 2; a heat sink 7 is disposed on the side of the cooling chip 2 opposite to the cooling body 1; the heat dissipation surface of the cooling chip 2 is in contact with the heat sink 7; a heat-conducting shell 3 is disposed on the outer side of the cooling body 1; the heat-conducting shell 3 is in contact with the heat sink 7; thereby, the inner wall of the heat-conducting shell 3, which is spaced apart from the cooling body 1, forms a heat insulation cavity 4 between the cooling body 1 and the heat sink 7.

[0021] The edges of the aforementioned heat-conducting shell 3 are all in contact with the surface of the heat sink 7; the aforementioned refrigeration body 1, heat-conducting shell 3 and heat sink 7 are all metal bodies with high thermal conductivity; the aforementioned refrigeration body 1 is a brass refrigeration body, the aforementioned heat-conducting shell 3 is an aluminum shell, and the aforementioned heat sink 7 is an aluminum plate.

[0022] The aforementioned refrigeration body 1 has at least one receiving groove 6 for embedding a mixing tube 100 or a dispensing head 200, and the heat-conducting housing 3 has a clearance through hole 31 for the mixing tube 100 or the dispensing head 200 to pass through.

[0023] The aforementioned heat insulation cavity 4 is filled with heat insulation material to further prevent heat conduction between the refrigeration body and the heat-conducting shell, ensuring that the temperature difference between the two and the surrounding environment is small, and preventing the generation of condensation. The aforementioned heat insulation material is foamed thermal insulation adhesive.

[0024] The aforementioned heat sink 7 is located on the side of the cooling chip 2 opposite to the cooling body 1 and has interconnected liquid inlet channel 9 and liquid outlet channel 10. Water circulation in the channels is achieved through external components such as pump body to cool the heat dissipation surface of the cooling chip. Compared with directly using external heat dissipation equipment to dissipate heat from the cooling chip, the combination of water circulation and large-area heat sink provides a larger heat dissipation area and is more convenient to install.

[0025] The cooling chip has two sides, a hot side and a cold side. The hot side of the cooling chip carries away some of the heat through the water flow in the heat sink. While ensuring the cooling effect, the heat sink itself still has a relatively hot and stable temperature close to room temperature. This heat is reused to heat the heat-conducting shell. The cold side of the cooling chip is used to cool the adhesive in the mixing tube. In existing technologies, plastic insulation material is wrapped around the outside of the refrigeration unit, but water droplets will still form on the surface of the insulation material over time. The mixing tube is wrapped with a brass refrigeration body to ensure uniform cooling and improve the uniformity of cooling of the adhesive liquid. The heat sink plate that is in contact with the hot surface of the cooling chip is made of aluminum plate and is connected to the heat-conducting shell, which is also made of aluminum. The heat sink plate, which is close to room temperature, is transferred to the heat-conducting shell and wraps the cooling body. The heat-conducting shell remains hot and will not change due to the low temperature of the internal cooling unit, preventing the temperature of the heat-conducting shell from becoming too low. When air comes into contact with the surface of the heat-conducting shell, water molecules will not condense due to excessive temperature difference. The insulation cavity is filled with heat-insulating cotton or filled with foam insulation adhesive, forming a structure similar to a refrigerator. In principle, this avoids the formation of condensate, making it more stable and durable than adding a water collection device.

[0026] The aforementioned cooling chip and external pump body are all purchased externally and fall within the scope of existing technology, so they will not be elaborated here. The cooling chip can be a semiconductor cooling chip.

[0027] When the above-mentioned anti-drip cooling component is used, it conducts the heat on the heat sink to the heat-conducting shell spaced apart from the cooling body. This can improve the heat dissipation efficiency of the heat sink and save energy. It can also reduce the temperature difference between the cooling body and the surrounding environment while ensuring the cooling effect, and avoid the large temperature difference between the heat-conducting shell and the environment caused by the low temperature of the cooling body. This fundamentally solves the problem of condensation dripping from the cooling body and adjacent components during the dispensing process, which affects product quality.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
