Technical Field
[0001] This utility model relates to the field of mold temperature controller technology, and in particular to a high-efficiency heat dissipation air-cooled mold temperature controller. Background Technology
[0002] Air-cooled mold temperature controllers, as important industrial temperature control equipment, are widely used in many industrial production fields such as plastic molding, die casting, rubber, chemicals, and food processing. Their core function is to precisely transfer heat to the mold or other controlled equipment, or absorb heat from it, by controlling the temperature of the circulating medium (usually water or oil), in order to maintain the stable temperature required for the production process. Traditional air-cooled mold temperature controllers typically achieve heating or cooling control of the circulating medium through the coordinated operation of built-in circulation pipes, heating components, and heat dissipation components.
[0003] However, existing air-cooled mold temperature controllers generally suffer from a technical challenge: insufficient consideration is given to heat dissipation of internal electronic components, especially critical control modules, power modules, relays, drivers, and various sensors located within the control box. These electronic components generate significant heat during prolonged continuous operation, particularly during high-power heating of the medium in the circulation pipeline. Since the control box is typically a relatively enclosed structure, or relies solely on natural convection and limited passive ventilation holes for heat dissipation, it is difficult to effectively dissipate this accumulated heat.
[0004] Traditional air-cooled mold temperature controllers primarily focus their cooling system on cooling the heat exchanger (used to cool the circulating medium), forcing external air through the heat exchanger to remove heat via a cooling fan. However, this airflow path is often independent of the control box's cooling path, or the control box only provides localized cooling through its own small fan or simple vents, failing to effectively coordinate with the main cooling airflow. This results in cooling blind spots or inefficiencies within the control box. Even when some mold temperature controllers attempt to incorporate fans within the control box, if the air intake and exhaust design is flawed and fails to create an efficient convection channel, heat remains difficult to dissipate effectively.
[0005] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an air-cooled mold temperature controller that can simultaneously and efficiently dissipate heat from the circulating medium and internal electronic control components, thereby significantly improving the stability and reliability of equipment operation.
[0007] This utility model is achieved through the following technical solution:
[0008] To solve the above-mentioned technical problems, this utility model provides a high-efficiency heat dissipation air-cooled mold temperature controller, including a chassis. The chassis is provided with a circulation pipeline, a heating component for heating the medium in the circulation pipeline, and a heat dissipation component for dissipating heat from the medium in the circulation pipeline. The heat dissipation component includes a cooling fan located at the top of the chassis and a heat exchanger located below the cooling fan and connected to the circulation pipeline. An electrical control box is located on the side of the heat exchanger. The electrical control box contains a control component for controlling the heating component and the heat dissipation component. An air intake grille is provided on the side wall of the chassis. The position of the air intake grille allows external air to be introduced and directed towards at least one side of the heat exchanger and at least one side of the electrical control box, so as to achieve simultaneous air intake cooling of the heat exchanger and the electrical control box.
[0009] To further address the technical problem to be solved by this utility model, this utility model provides a high-efficiency heat dissipation air-cooled mold temperature controller in which a gap is formed between the top of the heat exchanger and the inner top surface of the chassis. This gap constitutes an auxiliary heat dissipation air duct, which is used to guide part of the airflow from the area of the electrical control box to the suction area below the cooling fan.
[0010] In order to further solve the technical problem to be solved by this utility model, in the high-efficiency heat dissipation air-cooled mold temperature controller provided by this utility model, the electrical control box is provided with a plurality of air inlet holes on the side wall facing the air inlet grille, and the inner end of the air inlet holes is inclined upward.
[0011] In order to further solve the technical problem to be solved by this utility model, in the high-efficiency heat dissipation air-cooled mold temperature controller provided by this utility model, the top surface and / or the side facing the heat exchanger of the electrical control box are provided with a number of air outlets.
[0012] In order to further solve the technical problem to be solved by this utility model, in the high-efficiency heat dissipation air-cooled mold temperature controller provided by this utility model, a gap is formed between the side of the electrical control box facing the heat exchanger and the heat exchanger.
[0013] In order to further solve the technical problems to be solved by this utility model, the present utility model provides an efficient heat dissipation air-cooled mold temperature controller, wherein the circulation pipeline includes an inlet pipeline, a water pump and an outlet pipeline.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] This invention constructs a synergistic and efficient dual heat dissipation path by setting an air intake grille on the side wall of the chassis that can simultaneously face the heat exchanger and the electrical control box, combined with the optimized air inlet and outlet design of the electrical control box itself (such as upward-sloping air inlets and multiple outlets), and an auxiliary heat dissipation air duct formed between the top of the heat exchanger and the inner top surface of the chassis. This design not only ensures efficient cooling of the circulating medium, but more importantly, it achieves active and forced air cooling of the easily heat-accumulating electrical control box and its internal components, effectively solving the technical pain point of poor heat dissipation in the electrical control part of traditional mold temperature controllers. Its significant advantages include: greatly improving the heat dissipation efficiency of the electrical control components, reducing their operating temperature, thereby significantly improving the operational stability and control accuracy of the mold temperature controller, extending the service life of electronic components and the entire machine, reducing the failure rate and maintenance costs, and improving the continuous working capability of the equipment under high load or harsh environments.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] Please see Figures 1 to 5 This embodiment provides a high-efficiency heat dissipation air-cooled mold temperature controller. The air-cooled mold temperature controller mainly includes a casing 1, and a circulation pipeline 2, a heating component 3, and a heat dissipation component 4 disposed inside the casing 1.
[0024] Specifically, the circulation line 2 is used to contain and transport a temperature control medium (such as water or heat transfer oil), which circulates between the mold temperature controller and external heat-using equipment (such as the mold) to transfer heat.
[0025] Heating component 3 is connected to circulation pipeline 2 and is used to heat the medium in circulation pipeline 2. In practical applications, heating component 3 may include one or more electric heating tubes, heating wires or other types of heating elements, the operation of which is controlled by the control component described later to heat the medium to a preset temperature.
[0026] The heat dissipation component 4 is also connected to the circulation pipe 2, and is used to dissipate heat and cool the medium in the circulation pipe 2. For example... Figure 1 and Figure 2 As shown, in this embodiment, the heat dissipation assembly 4 specifically includes a cooling fan 41 located in the top area of the chassis 1, and a heat exchanger 42 located below the cooling fan 41 and connected to the circulation pipe 2. The heat exchanger 42 is typically a finned heat exchanger or other high-efficiency heat exchange structure. When the high-temperature medium in the circulation pipe 2 flows through the internal channels of the heat exchanger 42, it exchanges heat with the cooling air flowing through the external fins of the heat exchanger 42, thereby achieving the purpose of cooling. When the cooling fan 41 is working, it generates a strong airflow, forcing air to flow through the heat exchanger 42, thereby improving the heat dissipation efficiency.
[0027] Crucially, the mold temperature controller in this embodiment also includes an electrical control box 5. For example... Figure 2 and Figure 3 As shown, the electrical control box 5 is located on one side of the heat exchanger 42 (for example, schematically shown in the figure as the front or side of the heat exchanger 42, its specific location allowing it to be effectively cooled by the intake airflow). The electrical control box 5 houses a control component (not shown separately in the figure), which is the "brain" of the mold temperature controller. This control component controls the start and stop of the heating element 3 and its power, the start and stop of the cooling fan 41, and the operation of components such as the water pump 22 (described later), thereby achieving precise control of the circulating medium temperature.
[0028] To address the problem of poor heat dissipation in the electrical control box in existing technologies, this invention incorporates an air intake grille 43 on the side wall of the chassis 1. Figure 1 and Figure 2 As shown, the air intake grille 43 is positioned to draw in cooling air from outside the chassis, and the direction of this airflow is designed to be at least partially facing one side of the heat exchanger 42 (e.g., the right side shown in the figure) and one side of the electrical control box 5 (e.g., the right side shown in the figure). With this arrangement, the cooling air entering from the air intake grille 43 can be divided into two paths or form a coverage area. One part blows directly onto the heat exchanger 42 for efficient heat exchange, while the other part blows directly onto the outer wall of the electrical control box 5, or enters the interior of the electrical control box 5 through the structure described later. This achieves simultaneous air intake cooling of both the heat exchanger 42 and the electrical control box 5, significantly improving the heat dissipation effect of the electrical control box 5.
[0029] To further enhance the heat dissipation of the electrical control box 5 and optimize the overall airflow organization, this embodiment also has the following preferred structure:
[0030] like Figure 2 and Figure 3 As shown, a certain gap can be intentionally maintained between the top of the heat exchanger 42 and the inner top surface of the chassis 1. This gap is not an ineffective space, but rather forms an auxiliary heat dissipation duct 44. An important function of this auxiliary heat dissipation duct 44 is to guide the air that has already flowed through the electrical control box 5 area and absorbed its heat, or the hot air discharged from the air outlet of the electrical control box 5, to smoothly connect to the suction area below the cooling fan 41. In this way, the hot air discharged from the electrical control box 5 can be effectively drawn out of the chassis by the cooling fan 41, avoiding the accumulation of hot air inside the chassis and secondary heating of other components.
[0031] like Figures 2-4 As shown, to allow external cooling air to more effectively enter the electrical control box 5 and dissipate heat from the internal control components, the electrical control box 5 has a plurality of air intake holes 51 on at least the side wall facing the air intake grille 43 (e.g., the right side wall). These air intake holes 51 allow cooling air introduced from the air intake grille 43 to directly enter the interior of the electrical control box 5. More preferably, as shown... Figure 5 As shown, the inner end of the air inlet 51 is designed with an upward-sloping structure. This inclined design can guide the airflow upward, promoting the convection of hot and cold air inside the electrical control box; on the other hand, it can also prevent foreign objects such as dust or accidentally dripping liquids from directly entering the electrical control box, thereby improving the protection level of the electrical control box and the cleanliness of the internal components.
[0032] Accordingly, in order to allow the air entering the electrical control box 5 to flow out smoothly and carry away heat, the top surface of the electrical control box 5 and / or the side facing the heat exchanger 42 (i.e., the side adjacent to the heat exchanger 42) are provided with a plurality of air outlets 52, such as Figure 4 and Figure 5 As shown. Hot air, being less dense, naturally rises, so providing an vent 52 on the top surface facilitates its exhaust. Simultaneously, providing an vent 52 on the side facing the heat exchanger 42 allows the hot air exhausted from the electrical control box 5 to be directed to the auxiliary cooling duct 44 and ultimately drawn out by the cooling fan 41.
[0033] Furthermore, to ensure smooth airflow between the electrical control box 5 and the heat exchanger 42, especially when the air outlet 52 of the electrical control box 5 is located on its side facing the heat exchanger 42, a suitable gap is preferably formed between the side of the electrical control box 5 facing the heat exchanger 42 and the heat exchanger 42 (not separately labeled in the figure, but can be understood from the relative position). This gap ensures that the air discharged from the air outlet 52 has sufficient space to flow to the auxiliary heat dissipation duct 44 without being obstructed by the heat exchanger 42.
[0034] like Figure 2 As shown, the circulation pipeline 2 in this embodiment specifically includes an inlet pipeline 21, a water pump 22, and an outlet pipeline 23. The inlet pipeline 21 is used to receive returned medium or replenish new medium from external heating equipment. The water pump 22 is the circulation power source, used to drive the medium to flow throughout the circulation pipeline 2 and the external heating equipment. The outlet pipeline 23 is used to transport the temperature-controlled medium to the external heating equipment. The heating component 3 and the heat exchanger 42 (the core part of the heat dissipation component 4) are both connected in series or in parallel in the circulation loop formed by the inlet pipeline 21, the water pump 22, and the outlet pipeline 23.
[0035] Brief description of the work process:
[0036] When the mold temperature controller is working, the control component controls the heating component 3 to heat the medium according to the set temperature and the actual detected medium temperature, or controls the cooling fan 41 to work (while the medium flows through the heat exchanger 42) to dissipate heat from the medium.
[0037] During heat dissipation or heating operations (especially when high-power heating causes the control box to overheat significantly), the cooling fan 41 starts. External cooling air is drawn in through the air intake grille 43 on the side wall of the chassis 1. Part of the air flows directly to the heat exchanger 42 to cool the circulating medium flowing through it. The other part of the air is blown towards the control box 5 and enters the interior of the control box through the air intake 51 on the side wall to cool the internal control components and other electronic parts. The air that has absorbed heat is discharged from the air outlet 52 on the top and / or side of the control box 5. Some of the discharged hot air and the hot air flowing over the outer surface of the control box 5 will converge into the auxiliary cooling air duct 44 formed between the top of the heat exchanger 42 and the inner top surface of the chassis 1, and will eventually be drawn in by the powerful cooling fan 41 and discharged outside the chassis.
[0038] Through the above structural design, the air-cooled mold temperature controller of this utility model can not only efficiently control the temperature of the circulating medium, but more importantly, by optimizing the setting of the air inlet grille 43 and the air inlet and outlet structure of the electrical control box 5 and the auxiliary heat dissipation air duct 44, it can achieve efficient heat dissipation of the inside of the chassis (especially the heat exchanger) and the inside of the electrical control box at the same time, effectively avoiding the performance degradation or damage of the electrical control components due to heat accumulation, and significantly improving the operating stability and service life of the equipment.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model. For example, the specific shape and aperture of the air intake grille 43, the number, shape, and arrangement of the air intake holes 51 and air outlet holes 52 on the electrical control box 5, as well as the specific materials and dimensions of each component, can all be adjusted according to actual needs. As long as the described technical effect can be achieved, they should be considered to fall within the scope of protection of this utility model. The reference numerals in the drawings are also for convenience of description only and should not be construed as limiting this utility model.
