Abstract

An improved plate-type temperature control device includes: a housing, a plate-type temperature controller, and a descaling unit. The plate-type temperature controller and the descaling unit are disposed within the housing, which contains liquid. The plate-type temperature controller is immersed in the liquid to regulate its temperature. The heat exchange plates at the front and rear of the plate-type temperature controller are thickened. Several support strips are provided in the gap between each pair of adjacent plate-shaped fluid channels to prevent the heat exchange plates from bulging. Each support strip has connecting holes at both ends, and connecting rods pass through these holes. The thickness of the mating gaskets between adjacent plate-shaped fluid channels is the same as the thickness of the support strips, ensuring that the side walls of the adjacent fluid channels press firmly against the two sides of the support strips. This improved plate-type temperature control device avoids plate deformation, simplifies the structure, reduces manufacturing and assembly difficulty, optimizes the sealing effect, and enhances the overall stability of the device.

Description

Technical Field

[0001] This utility model belongs to the technical field of plate temperature control equipment, specifically referring to an improved plate temperature control equipment. Background Technology

[0002] Chinese invention patent CN119245396A discloses a plate-type temperature regulating device, such as Figure 1 As shown, it includes: a housing 1, a plate thermostat 2, and a descaling unit 3; the plate thermostat 2 and the descaling unit 3 are disposed inside the housing 1, which contains liquid, and the plate thermostat 2 is used to immerse itself in the liquid to regulate the temperature of the liquid; the plate thermostat 2 has multiple plate-shaped fluid channels arranged side by side at intervals from front to back; each plate-shaped fluid channel includes: a front heat exchange plate 21 and a rear heat exchange plate 22, the front heat exchange plate 21 is provided with a fluid inlet, and the rear heat exchange plate 22 is provided with a fluid inlet at the other end opposite to the fluid inlet. A fluid outlet is provided, and a closed gasket 23 is provided between the front heat exchange plate 21 and the rear heat exchange plate 22. The three are tightly fitted to form a sealed fluid channel. At the same corresponding position on the edge of all heat exchange plates 21, 22 and the closed gasket 23, there are connecting hole gaskets 24. All plate fluid channel heat exchange plates are locked together by connecting rods 25. In each pair of adjacent plate fluid channels, the outlet of the first plate fluid channel and the inlet of the second plate fluid channel are connected end to end by a mating gasket 26. The plate thermostat 2 in this scheme is based on the structure of existing plate heat exchangers, allowing only one type of fluid to pass through. The two plates through which the other type of fluid originally passed are not sealed, leaving a gap to allow the descaling unit to extend into the gap and disturb.

[0003] A traditional plate heat exchanger consists of a set of corrugated metal plates with four corner holes for the two liquids to pass through. The metal plates are mounted in a frame with fixed plates and movable clamping plates on one side and are clamped together with bolts. Gaskets are installed on the plates to seal the fluid passages and guide the fluids to flow alternately into their respective channels, thus facilitating heat exchange.

[0004] Traditional plate heat exchangers, because they exchange heat between two liquids, do not deform their plates. However, the plate thermostat in Chinese invention patent CN119245396A exhibits the following problems in practical use: 1. Apart from the mating gaskets and connecting gaskets, the parts between adjacent fluid channels are suspended. When the liquid flows within the fluid channels, the plates bulge out into the gaps, causing deformation. 2. Due to the plate deformation problem, to avoid adverse effects, a segmented splicing method with staggered connecting rods must be adopted. This directly leads to a more complex equipment structure and increases the difficulty of manufacturing and assembly. 3. The use of a one-piece connecting hole gasket design makes sealing measures difficult to implement, making it hard to guarantee a good sealing effect. To address these issues, the inventors conducted in-depth research and formulated corresponding improvement solutions. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an improved plate temperature control device that can avoid plate deformation.

[0006] This utility model is implemented as follows:

[0007] An improved plate temperature control device includes: a housing, a plate temperature controller, and a descaling unit; the plate temperature controller and the descaling unit are disposed in the housing, the housing contains liquid, and the plate temperature controller is used to immerse itself in the liquid to regulate the temperature of the liquid;

[0008] The plate thermostat has multiple plate-shaped fluid channels arranged side by side at intervals from front to back;

[0009] Each of the plate-shaped fluid channels includes: a front heat exchange plate and a rear heat exchange plate. One end of the front heat exchange plate is provided with a fluid inlet, and the other end of the rear heat exchange plate is provided with a fluid outlet. A closed gasket is provided between the front heat exchange plate and the rear heat exchange plate, and the three are closely fitted together to form a closed fluid channel.

[0010] All the heat exchange plates and the closed gaskets are provided with connecting hole gaskets at the same corresponding positions on their edges. The heat exchange plates of all the plate fluid channels are locked together by connecting rods. In each pair of adjacent plate fluid channels, the outlet of the previous plate fluid channel and the inlet of the next plate fluid channel are connected end to end by connecting gaskets.

[0011] The heat exchange plates at the very front and the very back are made of thickened plates;

[0012] Several support pads are provided in the gap between each pair of adjacent plate-shaped fluid channels to prevent the heat exchange plate from bulging. The two ends of the support pads are provided with connecting holes, and the connecting rod passes through the connecting holes of the support pads. The thickness of the mating gaskets of the two adjacent plate-shaped fluid channels is the same as the thickness of the support pads, so that the two side walls of the two adjacent fluid channels press against the two sides of the support pads.

[0013] The descaling unit continuously performs reciprocating synchronous circular motion within the gap via a drive unit, disturbing the sidewalls of the plate-shaped fluid channel to prevent scaling. The descaling unit includes multiple grid strips, each of which performs reciprocating synchronous circular motion within the gap between two adjacent support pads.

[0014] Furthermore, except for the two heat exchange plates at the very front and the very back which are integrated with the series connection hole gaskets, the other series connection hole gaskets are separate designs.

[0015] Furthermore, the design of the split-type connecting hole gasket is as follows: all the connecting hole gaskets on the same connecting rod are integrated into a sleeve, and the length of the sleeve is the same as the total thickness of all the connecting hole gaskets and the mating gaskets.

[0016] Furthermore, the plate-shaped fluid channel is triangular in shape.

[0017] Furthermore, the support pads are elongated and spaced apart in the vertical direction.

[0018] Furthermore, the plurality of the grid bars of the cleaning unit are connected together at the top to form a single unit for connecting the drive unit.

[0019] Furthermore, the bottoms of the grid strips located in the same space between the two support pads are connected as one unit.

[0020] The advantages of this utility model are:

[0021] 1. Solving the problem of plate bulging and deformation: Several support strips are installed in the gap between every two adjacent plate-shaped fluid channels, and the heat exchange plates of adjacent channels press against both sides of the support strips. Simultaneously, the connecting holes at both ends of the support strips allow for the insertion of connecting rods. This design fills the suspended area between adjacent fluid channels in existing equipment, excluding the gaskets, providing stable support for the plates and effectively preventing the plates from bulging and deforming into the gaps when liquid passes through, thus ensuring the stability of equipment operation and the service life of the plates.

[0022] 2. Simplified structure and reduced manufacturing and assembly difficulty: The support pads eliminate the need for segmented splicing and staggered connecting rods, resulting in a simpler overall structure. Furthermore, the connecting rods secure all heat exchange plates, closing gaskets, and support pads, making assembly more organized, lowering the technical barriers and operational difficulty of manufacturing and assembly, and improving production efficiency. In addition, while the front and rear heat exchange plates and connecting hole gaskets are integrated, the other connecting hole gaskets are separate, further reducing the manufacturing cost and difficulty of the heat exchange plates.

[0023] 3. Optimized Sealing Performance: Except for the front and rear heat exchange plates and the connecting hole gasket, which are integrated, the other connecting hole gaskets are designed separately. Compared to traditional integrated connecting hole gaskets, this design reduces the complexity of the sealing surface, making sealing measures easier to implement, effectively improving the sealing performance and reducing the risk of liquid leakage. Furthermore, the consistent thickness of the mating gasket and the support strip ensures a tight connection between adjacent channels, further enhancing the overall sealing performance.

[0024] 4. Enhanced overall equipment stability: The front and rear heat exchange plates are made of thicker plates, providing more robust end support for the entire plate thermostat. Combined with the locking action of the connecting rods, this allows the equipment to withstand greater pressure and vibration during operation, significantly improving overall structural stability. The descaling unit connects the grid bars at the bottom of the same space, further enhancing the robustness of the descaling unit. Attached Figure Description

Detailed Implementation

[0034] This utility model is an improvement upon Chinese invention patent CN119245396A, which describes a plate-type temperature regulating device (see [link]). Figures 2 to 6 As shown), its improvement lies in:

[0035] Among them, the first and last heat exchange plates of the plate thermostat 2 are thickened, more than three times thicker than the heat exchange plates in the middle.

[0036] Several support strips 5 are provided in the gap between each pair of adjacent plate-shaped fluid channels to prevent the heat exchange plates 21 and 22 from bulging. The support strips 5 are slender and arranged at intervals in the vertical direction. The two ends of the support strips 5 are provided with connecting holes 51, and the connecting rods 25 pass through the connecting holes 51. The thickness of the mating gaskets 26 between two adjacent plate-shaped fluid channels is the same as the thickness of the support strips 5, so that the side walls of the two adjacent fluid channels press against the two sides of the support strips 5.

[0037] Except for the first and last two heat exchange plates and the series connection hole gasket 24, which are integrated, the other series connection hole gaskets 24 are separate designs (only on the front and back). Figure 5 (As shown in the figure). The separate serial hole gaskets 24 can also be designed so that all the serial hole gaskets 24 on the same serial rod 25 are integrated into a sleeve, as long as the length of the sleeve is consistent with the total thickness of all the serial hole gaskets 24 and the mating gaskets 26.

[0038] The descaling unit 3, driven by a drive unit 4, continuously performs reciprocating synchronous circular motion within the gap, agitating the sidewalls of the plate-shaped fluid channel to prevent scaling. The descaling unit 3 includes multiple grid strips 31, each of which performs reciprocating synchronous circular motion within the gap between two adjacent support pads 5. The multiple grid strips 31 of the descaling unit 3 are connected together at the top for connecting the drive unit. The bottoms of the grid strips 31 located in the same space between two support pads 5 are connected together.

[0039] This utility model improves upon the existing technology and has at least the following beneficial effects:

[0040] 1. Solving the problem of plate bulging and deformation: Several support strips are installed in the gap between every two adjacent plate-shaped fluid channels, and the heat exchange plates of adjacent channels press against both sides of the support strips. Simultaneously, the connecting holes at both ends of the support strips allow for the insertion of connecting rods. This design fills the suspended area between adjacent fluid channels in existing equipment, excluding the gaskets, providing stable support for the plates and effectively preventing the plates from bulging and deforming into the gaps when liquid passes through, thus ensuring the stability of equipment operation and the service life of the plates.

[0041] 2. Simplified structure and reduced manufacturing and assembly difficulty: The support pads eliminate the need for segmented splicing and staggered connection rods, resulting in a simpler overall structure. Furthermore, the connection rods secure all heat exchange plates, closing gaskets, and support pads, making assembly more organized, lowering the technical barriers and operational difficulty of manufacturing and assembly, and improving production efficiency. In addition, while the front and rear heat exchange plates and connection hole gaskets are integrated, the other connection hole gaskets are separate. Alternatively, the separate connection hole gaskets can be designed so that all gaskets on the same connection rod are integrated into a single sleeve, provided the sleeve length matches the total thickness of all the connection hole gaskets. This design also reduces the manufacturing cost and difficulty of the heat exchange plates.

[0042] 3. Optimized Sealing Performance: Except for the front and rear heat exchange plates and the connecting hole gaskets, which are integrated, the other connecting hole gaskets are designed as separate units. Alternatively, the separate connecting hole gaskets can be designed so that all the connecting hole gaskets on the same connecting rod are integrated into a single sleeve, as long as the length of the sleeve matches the total thickness of all the connecting hole gaskets. Compared to the traditional integrated connecting hole design, this reduces the complexity of the sealing surface, making sealing measures easier to implement, effectively improving the sealing performance, and reducing the risk of liquid leakage. Furthermore, the design of the mating gasket and the support strip having the same thickness ensures the tightness of the connection between adjacent channels, further enhancing the overall sealing performance.

[0043] 4. Enhanced overall equipment stability: The front and rear heat exchange plates are made of thicker plates, providing more robust end support for the entire plate thermostat. Combined with the locking action of the connecting rods, this allows the equipment to withstand greater pressure and vibration during operation, significantly improving overall structural stability. The descaling unit connects the grid bars at the bottom of the same space, further enhancing the robustness of the descaling unit.

[0044] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
