constant temperature and humidity incubator

Abstract

This utility model discloses a constant temperature and humidity incubator belonging to the technical field of constant temperature and humidity incubators. It includes an incubator body, with a heat dissipation groove on the back of the shell. A heat-conducting plate is embedded in the inner wall of one side of the heat dissipation groove. One side of the heat-conducting plate extends into the shell of the incubator body and contacts its internal components. A cooling fin is disposed on the surface of the heat-conducting plate inside the heat dissipation groove. The heat-dissipating end of the cooling fin is connected to a heat dissipation fin. By employing heat transfer, the heat generated by the operation of the internal components of the incubator body is transferred to the interior of the heat dissipation groove using the heat-conducting plate, cooling fin, and heat dissipation fin. Since there is no communication between the heat dissipation groove and the interior of the incubator body, ventilation and heat dissipation can be directly applied to the interior of the heat dissipation groove during heat dissipation, thus ensuring heat dissipation efficiency while preventing dust accumulation.

Description

Technical Field

[0001] This utility model belongs to the technical field of constant temperature and humidity incubators, specifically relating to constant temperature and humidity incubators. Background Technology

[0002] Constant temperature and humidity incubators are experimental equipment used in production, testing, and scientific research in industries such as medicine, chemical industry, environmental protection, and agriculture for the cultivation and incubation of various microorganisms. They can be used to simulate natural environments, especially environments with temperature and humidity as the main parameters. Incubators are one of the most widely used devices in cell experiments. An incubator is a box-shaped device with controllable temperature, mainly used for culturing microorganisms, plant and animal cells. Some have a two-way temperature control system for both cooling and heating. They are basic experimental equipment in scientific research departments such as biology, agriculture, medicine, and environmental protection, and are widely used in constant temperature culture, constant temperature reaction and other experiments.

[0003] Currently, existing constant temperature and humidity incubators require real-time monitoring of internal temperature and humidity, necessitating timely adjustments through their internal heating, cooling, drying, and humidifying equipment. This results in prolonged operation of internal components, generating heat during operation. Traditionally, ventilation is used to dissipate heat from these components. However, ventilation exposes the components to external air, allowing dust to enter and accumulate on the surfaces, leading to overload operation, reduced efficiency, and shorter lifespan. Therefore, we propose the constant temperature and humidity incubator. Utility Model Content

[0004] The purpose of this invention is to provide a constant temperature and humidity incubator to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature and humidity incubator, comprising a constant temperature and humidity incubator body, a heat dissipation tank, and a cooling plate. The back of the shell of the constant temperature and humidity incubator body has a heat dissipation tank. A heat-conducting plate is embedded in the inner wall of one side of the heat dissipation tank. One side of the heat-conducting plate extends into the shell of the constant temperature and humidity incubator body and contacts its internal components. The other side of the heat-conducting plate is placed inside the heat dissipation tank. The periphery of the heat-conducting plate is fixed and sealed to the inner wall of the heat dissipation tank. A cooling plate is disposed on the surface of the heat-conducting plate placed inside the heat dissipation tank. The heat-absorbing end of the cooling plate is fixedly connected to the heat-conducting plate via thermally conductive silicone grease. The heat-releasing end of the cooling plate is fixedly connected to heat dissipation fins via thermally conductive silicone grease. The heat dissipation fins are placed inside the heat dissipation tank.

[0006] Preferably, the inner walls on both sides of the heat dissipation slot are respectively provided with an air inlet and an exhaust outlet that communicate with the outside, and a cooling fan is fixedly installed inside the air inlet and the exhaust outlet.

[0007] Preferably, a second heat-conducting rod and a first heat-conducting rod are fixedly installed on the outer periphery of the heat-absorbing end and the heat-releasing end of the cooling chip, respectively. The second heat-conducting rod is in close contact with the surface of the heat-conducting plate, and the first heat-conducting rod is in close contact with the heat dissipation fins.

[0008] Preferably, a heat insulation layer is filled between the heat-conducting plate and the heat dissipation fins. The heat insulation layer wraps around the outer periphery of the cooling chip, the first heat-conducting rod, and the second heat-conducting rod, but does not affect the contact between the second heat-conducting rod, the cooling chip, the first heat-conducting rod, the second heat-conducting rod, and the heat-conducting plate and the heat dissipation fins.

[0009] Preferably, the heat dissipation groove is provided with a sealing plate inside, and the sealing plate is fixed and sealed to the inner wall of the heat dissipation groove by sealant around its perimeter.

[0010] Preferably, a dustproof net is provided on the inner side of both the air inlet and the exhaust outlet, and the dustproof net completely covers the openings of the air inlet and the exhaust outlet.

[0011] Preferably, a display screen and a control panel are fixedly embedded on the top of the side of the constant temperature and humidity incubator body away from the heat dissipation groove, and a door is movably installed on the bottom of the side of the constant temperature and humidity incubator body where the display screen is located.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By employing heat transfer, heat generated by the operation of internal components of the constant temperature and humidity incubator is transferred to the interior of the heat dissipation tank using heat-conducting plates, cooling plates, and heat dissipation fins. Since there is no connection between the heat dissipation tank and the interior of the constant temperature and humidity incubator, ventilation and heat dissipation can be directly applied to the interior of the heat dissipation tank during heat dissipation, thereby ensuring heat dissipation efficiency while preventing dust accumulation.

[0013] 2. By setting a first heat-conducting rod and a second heat-conducting rod on both sides of the heat-absorbing end and the heat-releasing end of the cooling chip, so that the two rods contact the heat dissipation fins and the heat-conducting plate respectively, the contact area between the cooling chip and the heat-conducting plate and the heat dissipation fins is increased, thereby improving the heat dissipation efficiency. Furthermore, by using a heat insulation layer, the heat-absorbing end of the cooling chip is isolated, preventing the heat-absorbing end of the cooling chip from being affected by the temperature inside the heat dissipation groove, thus avoiding a reduction in its operating efficiency.

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.

[0017] Please see Figure 1-3 This utility model provides a technical solution for a constant temperature and humidity incubator: it includes a constant temperature and humidity incubator body 1, a heat dissipation groove 5, and a cooling plate 7. The back of the shell of the constant temperature and humidity incubator body 1 is provided with a heat dissipation groove 5. A heat-conducting plate 6 is embedded in the inner wall of one side of the heat dissipation groove 5. One side of the heat-conducting plate 6 extends into the shell of the constant temperature and humidity incubator body 1 and contacts its internal components. The other side of the heat-conducting plate 6 is placed inside the heat dissipation groove 5. The heat-conducting plate 6 is fixed and sealed to the inner wall of the heat dissipation groove 5 around its perimeter. A cooling plate 7 is provided on the surface of the heat-conducting plate 6 placed inside the heat dissipation groove 5. The heat-absorbing end of the cooling plate 7 is fixedly connected to the heat-conducting plate 6 through thermally conductive silicone grease. The heat-releasing end of the cooling plate 7 is fixedly connected to a heat dissipation fin 11 through thermally conductive silicone grease. The heat dissipation fin 11 is placed inside the heat dissipation groove 5.

[0018] Specifically, the inner walls on both sides of the heat sink 5 are respectively provided with an air inlet 13 and an exhaust outlet 14 that communicate with the outside. A cooling fan 15 is fixedly installed inside the air inlet 13 and the exhaust outlet 14.

[0019] Specifically, a second heat-conducting rod 9 and a first heat-conducting rod 8 are fixedly installed on the outer periphery of the heat-absorbing end and the heat-releasing end of the cooling chip 7, respectively. The second heat-conducting rod 9 is in close contact with the surface of the heat-conducting plate 6, and the first heat-conducting rod 8 is in close contact with the heat dissipation fins 11.

[0020] Specifically, a heat insulation layer 10 is filled between the heat-conducting plate 6 and the heat dissipation fins 11. The heat insulation layer 10 wraps around the outer periphery of the cooling chip 7, the first heat-conducting rod 8 and the second heat-conducting rod 9, but does not affect the contact between the second heat-conducting rod 9, the cooling chip 7, the first heat-conducting rod 8 and the second heat-conducting rod 9 and the heat-conducting plate 6 and the heat dissipation fins 11.

[0021] Specifically, a sealing plate 12 is provided inside the heat dissipation slot 5. The sealing plate 12 is fixed and sealed to the inner wall of the heat dissipation slot 5 by sealant.

[0022] Specifically, dustproof nets 16 are provided on the inner sides of both the air inlet 13 and the exhaust outlet 14, and the dustproof nets 16 completely cover the openings of the air inlet 13 and the exhaust outlet 14.

[0023] Specifically, a display screen 2 and a control panel 3 are fixedly embedded on the top of the side of the constant temperature and humidity incubator body 1 away from the heat dissipation groove 5, and a door 4 is movably installed on the bottom of the side of the constant temperature and humidity incubator body 1 where the display screen 2 is located.

[0024] In this embodiment, during use, the heat generated by the internal components of the constant temperature and humidity incubator 1 during prolonged operation can be absorbed by the heat-conducting plate 6 in contact with it, and then transferred to the heat-absorbing end of the cooling element 7 via the heat-conducting plate 6, or transferred to the heat-absorbing end of the cooling element 7 via the second heat-conducting rod 9. The second heat-conducting rod 9 increases the contact area between the heat-absorbing end of the cooling element 7 and the heat-conducting plate 6, thereby improving the efficiency of heat transfer. Then, the heat is transferred to the heat dissipation fins 11 via the heat-releasing end of the cooling element 7. At the same time, the first heat-conducting rod 8 increases the contact area between the heat-releasing end of the cooling element 7 and the heat dissipation fins 11, thereby improving the efficiency of heat transfer. Finally, the heat is amplified by the heat dissipation fins 11. The air is dispersed into the heat dissipation tank 5, and finally drawn from the outside by the cooling fan 15 in the air inlet 13. After being filtered by the dust filter 16, the air is injected into the heat dissipation tank 5. At the same time, the cooling fan 15 in the exhaust port 14 draws high-heat air from the inside of the heat dissipation tank 5 and discharges it to the outside, so that a stable airflow can be formed inside the heat dissipation tank 5, thereby quickly dissipating the heat and achieving the purpose of efficient heat dissipation. This design ensures efficient heat dissipation during use and effectively prevents external dust from entering the shell of the constant temperature and humidity incubator body 1, which would cause dust to adhere to the parts, affect the operation of the parts, and reduce their service life.
