Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical modules, and specifically relates to an industrial optical module that is easy to dissipate heat and does not deform. Background Technique
[0002] An optical module is composed of optoelectronic devices, functional circuits, optical interfaces, etc. The optoelectronic devices include two parts: transmitting and receiving. The function of the optical module is to convert an electrical signal into an optical signal at the transmitting end, and after transmission through an optical fiber, the receiving end converts the optical signal back into an electrical signal. An industrial optical module is a device used for bidirectional digital or analog signal transmission in an industrial communication system. Due to the complex industrial environment, it is usually in an environment with a relatively higher temperature than normal temperature. If heat cannot be dissipated in time, it will affect the normal use of the industrial optical module. Content of the Utility Model

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.
[0022] Embodiment 1: Please refer to Figures 1-3, the present utility model provides a technical solution: an industrial optical module that is easy to dissipate heat and does not deform, including: an optical module housing 1 and a circuit component disposed within the optical module housing 1;
[0023] Among them, a recessed groove 2 is formed on the outer upper surface of the optical module housing 1, a heat conducting plate is embedded within the recessed groove 2, and heat dissipating fins 3 are integrally formed on the upper surface of the heat conducting plate; a horizontal flow groove 4 is disposed on the front side of the recessed groove 2, and air outlet grooves 5 are formed at the front ends of both sides of the optical module housing 1, and the air outlet grooves 5 communicate with the flow groove 4.
[0024] Analysis of the above content: The circuit component is composed of existing optical emission components, optical reception components, control circuits, optical / electrical interfaces, etc., and its connection method also adopts existing technologies. Here, this solution does not change the circuit component, and it is the same as the existing conventional optical module, so it will not be elaborated here.
[0025] During use, the optical module is inserted into the corresponding interface. When the circuit component operates, the circuit component generates heat, heats the internal air, the air contacts and heats the optical module housing 1 and the heat conducting plate, the heat conducting plate and the heat dissipating fins 3 release the heat upward, the upper air expands due to heat and is output to the outside through the flow groove 4 and the air outlet grooves 5, and the air in the surrounding space replenishes the recessed groove 2, forming an air flow for continuous heat dissipation.
[0026] Embodiment Two: Please refer to Figures 1-3 , the present utility model provides a technical solution based on Embodiment One: Both the heat conducting plate and the heat dissipating fins 3 are made of aluminum alloy material or stainless steel material.
[0027] Analysis of the above content: Both aluminum alloy material and stainless steel material are materials with good heat conduction performance.
[0028] Embodiment Three: Please refer to Figures 1-3 , the present utility model provides a technical solution based on Embodiment One: Ventilation pipes 6 are embedded in the left and right side walls of the optical module housing 1, and the rear ends of the ventilation pipes 6 extend to the inner rear side of the recessed groove 2.
[0029] Analysis of the above content: The ventilation pipes 6 extend to the front of the optical module housing 1, and they can absorb air from the front side outside of the optical module housing 1 and replenish the recessed groove 2. Since the air on the front side is relatively far from the recessed groove 2 and generally has a lower temperature, the temperature difference between it and the heat conducting plate and the heat dissipating fins 3 is relatively large, resulting in good heat dissipation effect.
[0030] Embodiment Four: Please refer to Figures 1-3, the present utility model provides a technical solution based on Embodiment 3: An embedding groove 8 is formed on the rear inner side wall of the recessed groove 2. The rear end of the ventilation pipe 6 is connected with an air outlet pipe 9. One end of the air outlet pipe 9 away from the ventilation pipe 6 is embedded in the embedding groove 8, and a plurality of openings are evenly formed on the surface of the section of the air outlet pipe 9 located in the embedding groove 8.
[0031] Analysis of the above content: The air outlet pipe 9 can be laid along the opening direction of the embedding groove 8, so that the openings on the air outlet pipe 9 can face a plurality of heat dissipation fins 3, making the air outlet relatively uniform.
[0032] Embodiment 5: Please refer to Figures 1-3 , the present utility model provides a technical solution based on Embodiment 3: The front end of the ventilation pipe 6 droops to form a downward air suction section 7.
[0033] Analysis of the above content: With the arrangement of the downward air suction section 7, the downward air suction section 7 can suck in air from the lower part, avoiding the position of the upper air outlet groove 5. In this way, the temperature of the incoming air is relatively low, reducing the hot air discharged from the air outlet groove 5 from flowing back into the interior of the recessed groove 2 through the ventilation pipe 6.
[0034] Embodiment 6: Please refer to Figures 1-3 , the present utility model provides a technical solution based on Embodiment 1: A heat-conducting silicone grease layer is coated between the circuit assembly and the heat-conducting plate.
[0035] Analysis of the above content: The heat-conducting silicone grease layer is coated on the electrical components that generate heat in the circuit assembly (or the main heat-generating electrical components). The heat-conducting silicone grease layer has good heat-conducting properties, guiding the heat on the circuit assembly to the relatively lower-temperature heat-conducting plate and heat dissipation fins 3.
[0036] The above shows and describes the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model, and any reference signs in the claims should not be regarded as limiting the claimed rights.
