Description

Technical Field

[0001] The present application relates to the field of water temperature control equipment, and in particular to a water temperature cabinet with high efficiency heat exchange. Background Art

[0002] Water temperature cabinets, also known as water temperature control cabinets, are primarily used to regulate and maintain specific water temperatures to meet water requirements in various applications. In internal mixer applications, water temperature cabinets control water temperature to provide a stable heating or cooling environment for components such as the mixing chamber and rotor, ensuring temperature uniformity and stability during the rubber mixing process, thereby improving product quality and production efficiency.

[0003] In related technology, a water-cooled temperature control device for an internal mixer includes an internal circulation waterway and an external circulation waterway. The internal circulation waterway is used to supply hot water exchange liquid to the internal mixer and receive the hot water exchange liquid flowing out of the internal mixer. The external circulation waterway is used to circulate hot water supplied by hot water equipment (such as heat pump water heaters, hot water boilers, etc.) or cold water supplied by cold water equipment (such as chillers). The media in the internal and external circulation waterways exchange heat between the internal and external circulation waterways through a plate heat exchanger. Specifically, the plate heat exchanger includes two independent flow channels, one of which is connected in series with the internal circulation waterway, and the other is connected in series with the external circulation waterway.

[0004] However, the media in the inner circulation water channel and the outer circulation water channel are heat exchanged through two independent flow channels of the plate heat exchanger, and the heat exchange effect is relatively insufficient, and there is room for improvement. Utility Model Content

[0005] In order to improve the problem in the related art that the media in the inner circulation water channel and the outer circulation water channel exchange heat through two independent flow channels of the plate heat exchanger, resulting in relatively insufficient heat exchange effect, the present application provides a water temperature cabinet with high efficiency heat exchange.

[0006] This application provides a water temperature cabinet with high efficiency heat exchange, which adopts the following technical solutions:

[0007] A water temperature cabinet with high-efficiency heat exchange includes a frame and a plate heat exchanger arranged on the frame. The plate heat exchanger includes two independent flow channels, wherein the inlet of one independent flow channel is connected to an inlet pipe, and the outlet of the other independent flow channel is connected to an outflow pipe. The outflow pipe penetrates into the inlet pipe from the side close to the independent flow channel and exits at the side of the inlet pipe away from the independent flow channel.

[0008] By adopting the above technical solution, in actual use, high-temperature medium and low-temperature medium can be introduced into the inlet pipe and another independent channel respectively. When high-temperature medium is introduced into the inlet pipe and low-temperature medium is introduced into the other independent channel, the high-temperature medium flows through the inlet pipe and the corresponding independent flow channel in sequence, and the low-temperature medium flows through the corresponding flow channel and the outflow pipe in sequence, and the two media can exchange heat between the inlet pipe and the outflow pipe, and between the two independent flow channels. In this way, the heat exchange path of the high-temperature medium and the low-temperature medium is extended, which helps to improve the heat exchange effect between the two media. The outflow pipe passes through the inlet pipe, which reduces the arrangement of the pipes on the rack and helps to improve the neatness of the pipes on the water temperature cabinet.

[0009] It should be noted that high-temperature and low-temperature media are relatively speaking and are not divided by specific temperatures. For example, if the temperature of the medium entering the inlet pipe is 30°C and the temperature of the medium entering another independent channel is 10°C, then the medium entering the inlet pipe is the high-temperature medium, and the medium entering the corresponding independent channel is the low-temperature medium.

[0010] Preferably, the inlet of each independent flow channel is arranged in parallel with the outlet of another independent flow channel.

[0011] By adopting the above technical solution, the distance between the inlet of each independent flow channel and the outlet of another independent flow channel is shortened, which facilitates extending the length of the outflow pipe extending into the inlet pipe.

[0012] Preferably, a heat conducting member is fixed to the outer wall of the outlet pipe located inside the inlet pipe.

[0013] The adoption of the above technical solution helps to further improve the heat exchange effect between the two media.

[0014] Preferably, the heat conducting member is a heat conducting plate, and the heat conducting plate is arranged along the axial direction of the outflow pipe.

[0015] By adopting the above technical solution, the resistance caused by the heat conducting member to the flow of the medium is reduced, and the heat exchange effect between the two media is guaranteed.

[0016] Preferably, the heat conducting plate is spiral-shaped and is arranged around the outflow pipe.

[0017] By adopting the above technical solution, the heat conducting plate is set to a spiral shape, which helps to extend the length of the heat conducting plate, increase the contact area between the heat conducting plate and the corresponding medium, and further improve the heat exchange effect between the two media.

[0018] Preferably, the outflow pipe comprises a coaxially arranged penetration section, an intermediate section and an outlet section, the penetration section is connected to the corresponding independent flow channel outlet, and the two ends of the intermediate section are respectively threadedly connected to the corresponding ends of the penetration section and the outlet section;

[0019] The inlet pipe includes a first section and a tail section, the first section is communicated with the corresponding independent flow channel inlet, the ends of the first section and the tail section that are close to each other are threadedly connected, and the ends of the first section and the tail section that are away from each other are both bent, the penetration section passes through the side wall of the first section at the bend and penetrates into the first section, the exit section passes through the side wall of the tail section at the bend and penetrates into the tail section, and the axis of the part of the inlet pipe located between its two bent ends is coaxial with the middle section, and the heat conductor is located on the middle section.

[0020] By adopting the above technical solution, during actual installation, the middle section can be inserted into the first section, and the middle section can be rotated so that the end of the middle section is screwed into the end of the insertion section. Then, the tail section can be inserted into the tail section with the middle section facing away from the insertion section, and the tail section can be rotated so that the tail section is threadedly connected to the first section. At this time, the outlet section will also be threadedly connected to the middle section. This method facilitates the production of the matching structure of the outflow pipe and the inlet pipe.

[0021] Preferably, inner edges of the ends of the insertion section and the exit section that are close to each other are both chamfered.

[0022] By adopting the above technical solution, it is convenient for the entry section and the exit section to connect to the corresponding ends of the middle section.

[0023] Preferably, the frame is also provided with a supply pump and a three-way valve, the three-way valve is a two-inlet and one-outlet type, the water outlet of the supply pump is connected to one inlet of the three-way valve, and the outlet of the three-way valve is connected to the end of the inlet pipe away from the independent channel.

[0024] By adopting the above technical solution, the three-way valve can be switched according to actual needs, which helps to improve the applicability of the water temperature cabinet.

[0025] For example, when a water pump is already connected in series in the internal circulation water channel or the external circulation water channel, or the medium in the internal circulation water channel or the external circulation water channel is at high pressure, the internal circulation water channel or the external circulation water channel can be directly connected to the corresponding inlet of the three-way valve, avoiding the supply pump; when a water pump is not connected in series in the internal circulation water channel or the external circulation water channel, or the medium in the internal circulation water channel or the external circulation water channel is at low pressure, the internal circulation water channel or the external circulation water channel can be connected to the water suction port of the supply pump.

[0026] Preferably, the lower side of the frame is provided with running wheels for moving the frame.

[0027] By adopting the above technical solution, the water temperature cabinet can be easily moved.

[0028] Preferably, the running wheel is a single-brake universal wheel.

[0029] By adopting the above technical solution, the position of the water temperature cabinet is easily fixed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The present application is further described in detail below with reference to the accompanying drawings.

[0037] In related technologies, a plate heat exchanger contains two independent flow channels, one for circulating a high-temperature medium and the other for circulating a low-temperature medium. "High temperature" and "low temperature" are relative terms, and the specific temperatures depend on the actual application scenario. In one flow channel, a high-temperature medium (such as steam, hot water, or other high-temperature fluid) flows; this flow channel is also called the high-temperature flow channel. In the other flow channel, a low-temperature medium (such as cold water, air, or other fluid that needs to be heated) flows in the opposite or same direction, thereby cooling the high-temperature medium and heating the low-temperature medium. This flow channel is also called the low-temperature flow channel.

[0038] The embodiment of the present application discloses a water temperature cabinet with high efficiency heat exchange.

[0039] Reference Figure 1 and Figure 2 The water temperature cabinet for efficient heat exchange comprises a frame 1 and a plate heat exchanger 2 fixed to the frame 1. The frame 1 is a horizontal rectangular frame, with running wheels 11 installed at the four corners of the lower side of the frame 1. In this embodiment, at least one running wheel 11 is a single-brake universal wheel. The plate heat exchanger 2 is placed vertically and includes two independent flow channels 21 (see Figure 3), the inlet of each independent flow channel 21 is arranged in parallel with the outlet of the other independent flow channel 21. Of the two parallel inlets and outlets of the independent flow channels 21, the inlet of one independent flow channel 21 is connected to the inlet pipe 3, and the outlet of the other independent flow channel 21 is connected to the outlet pipe 4. The outlet pipe 4 passes through the inlet pipe 3 from the side close to the independent flow channel 21 and exits on the side of the inlet pipe 3 away from the independent flow channel 21. The inlet pipe 3 corresponds to the inlet of the two independent flow channels 21 one-to-one, and the outlet pipe 4 corresponds to the outlet of the two independent flow channels 21 one-to-one.

[0040] In actual use, high-temperature medium and low-temperature medium can be respectively introduced into the two inlet pipes 3, and the high-temperature medium and low-temperature medium will flow through the corresponding inlet pipe 3, independent flow channel 21 and outlet pipe 4 in sequence, and the two media can exchange heat between the inlet pipe 3 and the outlet pipe 4 and the two independent flow channels 21.

[0041] See also Figure 4 and Figure 5 The connection structure and method between each inlet pipe 3 and the corresponding outlet pipe 4 are consistent. Now, one group of inlet pipes 3 and corresponding outlet pipes 4 is taken as an example for explanation.

[0042] The outflow pipe 4 includes a coaxially arranged penetration section 41, an intermediate section 42 and an outlet section 43. The penetration section 41 is connected to the outlet of the corresponding independent flow channel 21, and the two ends of the intermediate section 42 penetrate the corresponding ends of the penetration section 41 and the outlet section 43 respectively and are threadedly connected. A heat conducting member is fixed to the outer wall of the intermediate section 42, and the heat conducting member is a heat conducting plate 421. The two heat conducting plates 421 are spiral-shaped, and the heat conducting plates 421 are arranged around the outflow pipe 4 and extend axially along the outflow pipe 4. Three heat conducting plates 421 are evenly spaced around the intermediate section 42. In order to facilitate the threaded connection of the two ends of the intermediate section 42 to the penetration section 41 and the outlet section 43 respectively, the inner edges of the ends of the penetration section 41 and the outlet section 43 that are close to each other are chamfered.

[0043] The inlet pipe 3 comprises a first section 31 and a tail section 32. The first section 31 communicates with the inlet of the corresponding independent flow channel 21, and the ends of the first and tail sections 31, 32, facing each other, are threadedly connected. The ends of the first and tail sections 31, 32, facing away from each other, are both bent. The entry section 41 penetrates the sidewall of the first section 31 at the bend and enters the first section 31. The exit section 43 penetrates the sidewall of the tail section 32 at the bend and enters the tail section 32. The axis of the portion of the inlet pipe 3 located between the two bent ends is coaxial with the intermediate section 42.

[0044] During actual installation, the middle section 42 can be inserted into the first section 31, and the middle section 42 can be rotated so that the end of the middle section 42 is screwed into the end of the insertion section 41; then, the tail section 32 is made coaxial with the first section 31, and one end of the middle section 42 away from the insertion section 41 is inserted into the tail section 32, and the tail section 32 is rotated so that the tail section 32 is threadedly connected to the first section 31. At this time, the exit section 43 will also be threadedly connected to the middle section 42.

[0045] See also Figure 1 and Figure 2 The frame 1 is also provided with a supply pump 5 and a three-way valve 6. The three-way valve 6 is a two-inlet, one-outlet type. The water outlet of the supply pump 5 is connected to one inlet of the three-way valve 6, and the outlet of the three-way valve 6 is connected to the end of the inlet pipe 3 that is away from the independent channel. In addition, both the supply pump 5 and the three-way valve 6 correspond one-to-one with the inlet pipe 3.

[0046] Of course, in other embodiments, a thermometer, a flow meter, etc. can be set on the inlet pipe 3 or the outlet pipe 4, and the thermometer is used to detect the medium temperature, and the flow meter is used to detect the medium flow. Compared with the conventional method, it is not repeated here.

[0047] The implementation principle of a water temperature cabinet with high efficiency heat exchange in the embodiment of the present application is as follows: in actual use, the three-way valve 6 can be switched according to actual needs. Here, taking the example that the inner and outer circulation water circuits do not have water pumps, the water inlet of one supply pump 5 and the corresponding end of the outflow pipe 4 away from the independent flow channel 21 are connected in series with the inner circulation water circuit, and the water inlet of the other supply pump 5 and the end of the outflow pipe 4 away from the independent flow channel 21 are connected in series with the outer circulation water circuit. The outer circulation water circuit is supplied with hot water by a hot water device (such as a heat pump hot water unit, a hot water boiler, etc.) or with cold water by a cold water device (such as a chiller), thereby realizing heat exchange between the inner and outer circulation water circuits and providing a relatively stable heating or cooling environment for the internal mixer.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
