Description

Technical Field

[0001] This utility model relates to equipment for conveying hot and cold media, and more particularly to an integrated hot and cold temperature control device. Background Technology

[0002] In existing technologies, for equipment requiring temperature control using refrigerants or heating media, independent high-temperature or low-temperature control systems are typically used to provide specified fluid temperatures and flow rates, thereby providing temperature control for industrial products. Traditional temperature control equipment lacks the range of applications suitable for high and low temperature molding systems. Most temperature control devices are limited to a single high-temperature or low-temperature control system. The switching process between high and low temperature control results in significant energy loss. Furthermore, for both high and low temperature systems, the cooling and heating process leads to contact between media at different temperatures, causing unstable fluid flow rates and affecting normal fluid circulation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an integrated cold and hot temperature control device that is compact in structure, has high temperature control efficiency, and is easy to regulate in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] An integrated heating and cooling temperature control device includes an oil tank, a plate heat exchanger, a heater, a circulating oil pump, a medium tank, a medium circulation pump, an evaporator, a condenser, a compressor, and an electric three-way proportional valve. The plate heat exchanger has a medium channel and an oil channel. The oil outlet of the oil tank, the circulating oil pump, the heater, and the oil channel of the plate heat exchanger are connected in sequence by oil pipes. The outlet of the oil channel is connected to an outwardly extending oil outlet pipe. The refrigerant pipes of the evaporator and the condenser are respectively connected to the refrigerant end of the compressor. The outlet of the medium tank, the medium circulation pump, the medium channel of the plate heat exchanger, the cooling chamber of the evaporator, and the return port of the medium tank are connected in sequence. The left and right ends of the electric three-way proportional valve are connected in series to the oil outlet pipe, and the middle end of the electric three-way proportional valve is connected to the oil channel inlet of the plate heat exchanger.

[0006] Preferably, the system includes a frame with an upper space and a lower space. The condenser and the oil tank are located in the upper space, while the plate heat exchanger, heater, circulating oil pump, medium tank, medium circulation pump, evaporator, compressor, and electric three-way proportional valve are all located in the lower space.

[0007] Preferably, the evaporator is a cylindrical shell-and-tube evaporator, and the evaporator is arranged laterally in the lower space.

[0008] Preferably, two supports are fixed in the lower space, and the evaporator is fixed on the two supports.

[0009] Preferably, the upper space is provided with two condensers, which are located near the two sides of the frame.

[0010] Preferably, the top of the rack is provided with a fan cover, and a fan is provided inside the fan cover, the fan facing the area between the two condensers.

[0011] Preferably, the condenser is a finned condenser.

[0012] In the integrated heating and cooling temperature control device disclosed in this utility model, the medium tank is used to hold water or other fluid media. When the medium circulation pump is running, it drives the media in the medium tank to circulate between the medium channel of the plate heat exchanger, the cooling chamber of the evaporator, and the medium tank. When the compressor starts, the cooling chamber of the evaporator is cooled based on the cooperation of the evaporator and the condenser, thereby cooling the media flowing into the medium channel of the plate heat exchanger. The plate heat exchanger is used to cool the oil in its oil channel. When the circulating oil pump is running, it can transport the low-temperature oil to the production line, and then it flows back to the oil storage tank through the oil return passage of the production line, thus achieving cooling. During the heating process, by controlling the heater to be powered on, the oil in the oil circuit is heated. Then, the electric three-way proportional valve is activated by the electrical signal, so that the cold oil and hot oil are mixed in an appropriate ratio, and the oil at the target temperature is delivered to the oil production line, thereby realizing flexible control of oil temperature and higher temperature control efficiency. In addition, this utility model has a high degree of integration and a more compact structure, which better meets the application requirements. Attached Figure Description

[0016] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0017] This utility model discloses an integrated cold and hot temperature control device, combined with Figures 1 to 3As shown, it includes an oil tank 1, a plate heat exchanger 2, a heater 3, a circulating oil pump 4, a medium tank 5, a medium circulation pump 6, an evaporator 7, a condenser 8, a compressor 9, and an electric three-way proportional valve 10. The plate heat exchanger 2 is provided with a medium channel and an oil channel. The oil outlet of the oil tank 1, the circulating oil pump 4, the heater 3, and the oil channel of the plate heat exchanger 2 are connected in sequence by oil pipes. The outlet of the oil channel is connected to an outwardly extending oil outlet pipe 20. The refrigerant pipes of the evaporator 7 and the condenser 8 are respectively connected to the refrigerant end of the compressor 9. The outlet of the medium tank 5, the medium circulation pump 6, the medium channel of the plate heat exchanger 2, the cooling chamber of the evaporator 7, and the return port of the medium tank 5 are connected in sequence. The left and right ends of the electric three-way proportional valve 10 are connected in series to the oil outlet pipe 20, and the middle end of the electric three-way proportional valve 10 is connected to the oil channel inlet of the plate heat exchanger 2.

[0018] In the above structure, the medium tank 5 is used to hold water or other fluid media. When the medium circulation pump 6 is running, it drives the medium in the medium tank 5 to circulate between the medium channel of the plate heat exchanger 2, the cooling chamber of the evaporator 7, and the medium tank 5. When the compressor 9 is started, the cooling chamber of the evaporator 7 is cooled by the cooperation of the evaporator 7 and the condenser 8, thereby cooling the medium flowing into the medium channel of the plate heat exchanger 2. The oil in the oil channel of the plate heat exchanger 2 is cooled by the plate heat exchanger 2. When the circulating oil pump 4 is running, it can transport the low-temperature oil to the production line, and then it flows back to the oil storage tank 1 through the oil return passage of the production line, thereby achieving the cooling treatment. During the heating process, the oil in the oil circuit is heated by controlling the heater 3 to be powered on. Then, the electric three-way proportional valve 10 is activated by the electrical signal to mix the cold oil and hot oil in an appropriate ratio and deliver the oil at the target temperature to the oil production line. This achieves flexible control of oil temperature and higher temperature control efficiency. In addition, this utility model has a high degree of integration and a more compact structure, which better meets the application requirements.

[0019] To further improve the compactness of the structure of this utility model, and to make the internal mechanism distribution more reasonable, combined with Figures 1 to 3 As shown, this embodiment includes a frame 11, on which an upper space 12 and a lower space 13 are provided. The condenser 8 and the oil tank 1 are located in the upper space 12, and the plate heat exchanger 2, heater 3, circulating oil pump 4, medium tank 5, medium circulation pump 6, evaporator 7, compressor 9 and electric three-way proportional valve 10 are all located in the lower space 13.

[0020] In the above structure, small and heavy components are all located in the lower space 13. This structural layout can make the center of gravity of the whole machine lower, and thus place it more stably in the designated position.

[0021] To achieve rapid cooling of the medium, in this embodiment, the evaporator 7 is a cylindrical shell-and-tube evaporator, and the evaporator 7 is arranged laterally in the lower space 13.

[0022] In this embodiment, since the evaporator 7 is cylindrical and installed horizontally, two supports 15 are fixed in the lower space 13 to reliably fix the evaporator 7, and the evaporator 7 is fixed on the two supports 15. Specifically, the upper end of the support 15 has an arc-shaped notch that can fit the outer surface of the evaporator 7.

[0023] In order to improve the cooling efficiency of the medium, in this embodiment, two condensers 8 are provided in the upper space 12, and the two condensers 8 are respectively close to the two sides of the frame 11.

[0024] As a preferred method, combined Figure 1 and Figure 2 As shown, the top of the frame 11 is provided with a fan cover 16, and a fan is installed inside the fan cover 16. The fan faces the area between the two condensers 8. Further, the condenser 8 is a finned condenser.

[0025] Compared to existing technologies, this invention features a built-in energy storage mechanism, enabling faster heating and cooling with a shorter temperature stabilization time. Furthermore, the indirect heat exchange between the hot and cold flow channels avoids direct fluid contact, thereby reducing energy loss and making the entire device more energy-efficient.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
