Description

Technical Field

[0001] This utility model relates to the technical field of temperature control elements, and in particular to an intelligent temperature controller. Background Technology

[0002] After prolonged operation, the lubricating oil in the equipment's lubrication and hydraulic systems can become overheated and thin, affecting lubrication and hydraulic drive performance. Adding a cooler directly would result in excessively low initial operating temperatures, causing the lubricating and hydraulic oils to become too viscous, damaging the meshing mechanism and wasting significant energy. Therefore, a temperature control valve is installed on the cooler's connecting pipeline to automatically open and close the cooler based on oil temperature changes, ensuring safe, energy-efficient, and effective operation of the equipment.

[0003] The temperature control valve requires a temperature-sensing valve core, which is pushed open and closed by a push rod based on temperature changes. During storage, transportation, and disassembly, the temperature control valve core is prone to detachment. If oil or impurities enter the valve cavity after the push rod detaches, it will directly affect the opening accuracy of the temperature-sensing valve core. These impurities may even scratch the internal sealing rubber parts of the valve core, causing damage and failure. Furthermore, if abnormal temperature sensing or misalignment occurs inside the machine, the push rod can easily fall into the oil circuit, causing significant damage to the equipment.

[0035] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0036] like Figure 1-4 As shown in the following embodiment, an intelligent temperature controller is provided.

[0037] Example 1

[0038] A smart temperature controller includes a housing 100 with an opening on one side, the opening of which is sealed by a cover 200; a through hole is provided on the cover 200, through which a push rod 300 passes; a rubber tube 400 is disposed inside the housing 100, and the push rod 300 is located inside the rubber tube 400; an expansion material 1 is filled between the housing 100 and the rubber tube 400.

[0039] A sealing ring 2 is provided between the cover 200 and the push rod 300. The sealing ring 2 is provided with a positioning spring stop assembly 500 to sense the extreme position of the push rod 300.

[0040] The above is the basic scheme of this embodiment.

[0041] Specific reference Figure 1As shown, the thermostat body in this embodiment is a conventional wax-based temperature sensing element. When the external environment heats up, heat is transferred to the interior of the housing 100 through the housing 100. The expansion material 1 inside the housing 100 expands due to heat, generating pressure on the tube 400. The tube 400 deforms and is squeezed towards the cover 200, thereby pushing the push rod 300 in the through hole and causing the push rod 300 to move outward.

[0042] During its movement, the push rod 300 is always in an interference fit with the sealing ring 2 to keep the inside of the housing 100 sealed. When the push rod 300 moves to its limit position, that is, when it is in its longest extended position, the positioning spring stop assembly 500 generates a spring stop action on the push rod 300 to stop the push rod 300 and keep it stationary at the limit position. At the same time, the sensing component outside the push rod 300 senses the position status of the push rod 300 and transmits the position signal of the push rod 300 to the control system for control.

[0043] In addition, referring to the novel temperature sensing element disclosed in Chinese utility model patent CN216344260U, a limiting component is usually provided on the cover 200 to limit the push rod 300 to prevent it from extending completely outside the housing and detaching from the outer shell.

[0044] During reset, the external environment cools down, the expansion material 1 contracts, and the hose 400 resets. At this time, the limit component outside the temperature controller pushes the push rod 300 back into the housing 100 to reset.

[0045] Preferably, in this embodiment, the expanding material 1 is a mixture of graphite and wax.

[0046] In existing technologies, paraffin wax is typically used as the expansion material 1. While paraffin wax, as a phase change material, has a high heat storage density, its thermal conductivity is low (approximately 0.2 W / m·K), resulting in a slow heat storage / release rate. Meanwhile, graphite, due to its loose, porous, worm-like structure, has a high thermal conductivity (up to nine times that of pure paraffin wax), effectively accelerating heat transfer 10. Choosing a mixture of graphite and wax as the expansion material 1 effectively solves the problem of the slow heat storage / release rate of paraffin wax, significantly improving the temperature response rate of the thermostat.

[0047] Specifically, the positioning spring stop assembly 500 includes a spring stop sleeve 510, which is hollow inside and has an opening on one side for inserting an elastic support member and pushing the spring stop sleeve 510 toward the push rod 300.

[0048] The push rod 300 is provided with an annular spring stop ring 301.

[0049] Specific reference Figure 2As shown, the inner ring of the sealing ring 2 is provided with a groove, the spring stop sleeve 510 is a hollow structure with a spring stop chamber, one side of the spring stop sleeve 510 is open and communicates with the spring stop chamber, the elastic top support is inserted into the spring stop chamber through the opening and can move within a small range in the spring stop chamber.

[0050] To ensure a tight seal, the spring stop sleeve 510 and the groove are tightly fitted and fixed.

[0051] The end of the elastic support protrudes, causing the inner side of the spring stop sleeve 510 to bulge out and be able to be embedded in the spring stop ring 301.

[0052] In this embodiment, the spring stop sleeve 510 is an annular shell 100 structure, and its inner wall protrudes under the action of the elastic support member, and contacts and seals with the push rod 300.

[0053] Preferably, in this embodiment, the elastic support member is a movable block 520 with an arc-shaped end. The movable block 520 can be driven by the elastic member to move radially along the push rod 300 within the spring stop sleeve 510.

[0054] Specifically, the elastic element drives the movable block 520, and the driving force is radial along the push rod 300, thereby giving the elastic support a tendency to move toward the side of the elastic support.

[0055] In this embodiment, the movable block 520 is provided with a spring groove, and the elastic element is located in the spring groove.

[0056] Preferably, for ease of assembly, the movable block 520 is provided with an installation channel 522 extending from the spring groove. The installation channel 522 extends to an opening on one side of the movable block 520, through which the elastic element is inserted into the spring groove along the installation channel 522.

[0057] Preferably, the opening of the mounting channel 522 and the opening of the spring sleeve 510 are located on the same side.

[0058] Since the spring stop sleeve 510 has an annular shell structure, the spring stop chamber also has an annular structure. In order to ensure contact with the push rod 300 in the circumferential direction, in this embodiment, multiple movable blocks 520 are provided and surround the push rod 300 in the circumferential direction.

[0059] The elastic element is a telescopic spring 530 arranged in a ring.

[0060] Multiple movable blocks 520 are arranged circumferentially, and an ejector head 521 is provided on the end face of the movable block 520 to push against the inner ring wall of the spring stop sleeve 510, so that the inner ring wall of the spring stop sleeve 510 is subjected to uniform annular multi-point pushing, so that the inner ring of the spring stop sleeve 510 contacts the push rod 300.

[0061] Preferably, in this embodiment, the ejector head 521 is configured as an arc-shaped spherical structure.

[0062] In this embodiment, in order to generate a uniform driving force on the multiple movable blocks 520, the elastic element is a telescopic spring 530. In its natural state, the telescopic spring 530 has a driving force toward the center, thereby causing the multiple movable blocks 520 arranged in a circle to move toward the center, that is, to hold the push rod 300 tightly.

[0063] Example 2

[0064] This embodiment is an improvement based on Embodiment 1 or Embodiment 2. Its purpose is to provide a new structure for the hose 400 to improve the thrust response efficiency of the hose 400 to the push rod 300. The specific implementation method is as follows:

[0065] The hose 400 is configured as a corrugated pipe.

[0066] Specific reference Figure 3 As shown, in this embodiment, the middle part of the hose 400 is set with a corrugated structure. When the hose 400 is squeezed, due to the special nature of the corrugated structure, the support strength of the middle part is greater than that of the flat part at the bottom. Therefore, the expansion material 1 preferentially supports the bottom of the hose 400. As a result, the hose 400 deforms and contracts from the bottom, that is, it preferentially drives the bottom of the push rod 300, pushing the push rod 300 outward.

[0067] Preferably, in this embodiment, the expansion joint 410 of the hose 400 is located in the middle.

[0068] In the existing technology, the hose 400 structure has insufficient lateral support. When the expansion material 1 compresses the hose 400, it simultaneously or even preferentially compresses the side of the hose 400, failing to drive the push rod 300 immediately, thus slowing down the temperature response rate of the thermostat. Therefore, in this embodiment, the bottom of the hose 400 is set as a conventional flat structure, while an expansion joint 410 is only provided in the middle of the hose 400. The expansion material 1 preferentially compresses the bottom of the hose 400, thereby pushing the bottom of the push rod.

[0069] Preferably, in this embodiment, the axial width of each expansion joint 410 protruding outward from the rubber tube 400 in the corrugated section is inconsistent, preferably decreasing sequentially from bottom to top, thereby reducing the supporting force of the corrugated section sequentially. During deformation, it is preferentially compressed and deformed from the bottom first, as detailed in the following figure. Figure 3 As shown.

[0070] Example 3

[0071] This embodiment is an improvement based on Embodiment 1. Its purpose is to provide a new housing structure to increase the thermal conductivity of the housing 100 and improve the temperature response rate of the thermostat.

[0072] The specific testing method is as follows: heat-conducting fins 110 are provided on the inner wall of the housing 100. The heat-conducting fins 110 are configured as wedge-shaped structures, and the radial length decreases sequentially along the axial direction.

[0073] Specific reference Figure 4 As shown, in this embodiment, heat-conducting fins 110 are provided on the inner wall of the shell 100. When the external temperature rises, heat is transferred through the shell 100 and the heat-conducting fins 110. The expansion material 1 contacts the heat-conducting fins 110, increasing the contact area between the expansion material 1 and the heat conduction surface, thereby improving the heat transfer efficiency.

[0074] Preferably, the heat-conducting fins 110 are thin sheet structures and are arranged in multiple circumferences.

[0075] Meanwhile, in order to ensure that most of the heat can be transferred to the bottom of the housing 100 so that the expansion material 1 expands from the bottom of the tube 400 and compresses the tube 400, the heat-conducting fins 110 in this embodiment are preferably wedge-shaped structures, that is, the width of the lower fin is greater than the width of the upper fin, so that the contact area between the lower expansion material 1 and the heat-conducting fins 110 is greater than that of the upper one, so that most of the heat can be transferred to the lower expansion material 1, achieving the effect of preferential expansion of the lower expansion material 1.

[0076] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
