Description

Technical Field

[0001] This utility model belongs to the technical field of thermal insulation structure for heat medium pump rooms, and particularly relates to a thermal insulation structure for heat medium pump rooms. Background Technology

[0002] Thermal insulation structure of heat medium pump room refers to a structural system that forms a thermal barrier between the pump room and adjacent spaces by setting up insulation material layers, insulation boards or air gaps to reduce heat conduction and radiation. At the same time, it can be combined with natural or mechanical ventilation to achieve heat dispersion and temperature regulation, thereby maintaining a stable ambient temperature in adjacent spaces, ensuring the safe operation of equipment and improving building energy efficiency.

[0003] However, existing insulation devices mostly use single-layer polystyrene boards or foam plastics as insulation materials. With a simple structure, once the thermal conductivity is high, it is difficult to effectively block the heat transfer from the heat medium pump room to the power distribution room. At the same time, the lack of air gap and forced ventilation design causes heat to accumulate between the walls, forming a significant thermal bridge effect. In addition, static insulation structures cannot achieve active heat dissipation, with high heat flux density and small temperature gradient. During long-term operation, the temperature of the power distribution room is prone to exceed the standard, affecting the safety and service life of electrical equipment. Utility Model Content

[0004] This utility model provides a thermal insulation structure for a heat transfer pump room, aiming to solve the problems of existing thermal insulation devices that mostly use single-layer polystyrene boards or foam plastics as insulation materials. These single-layer structures, once having a high thermal conductivity, are difficult to effectively block the heat transfer from the heat transfer pump room to the power distribution room. At the same time, the lack of air gaps and forced ventilation designs leads to heat accumulation between the walls, forming a significant thermal bridge effect. In addition, static thermal insulation structures cannot achieve active heat dissipation, resulting in high heat flux density and small temperature gradient. During long-term operation, the temperature of the power distribution room is prone to exceed the standard, affecting the safety and service life of electrical equipment.

[0007] Preferably, the ventilation assembly includes: a lower fan frame bolted to the lower side of the closed structure formed by the concrete floor, concrete wall, galvanized keel layer and rock wool insulation layer; a connecting plate installed on the top surface of the lower fan frame; fan blades installed inside the lower fan frame; an upper air outlet frame fixedly connected to the upper side of the connecting plate; an air outlet opened inside the upper air outlet frame; a sloped air guide plate fixedly connected to the lower side of the inner edge of the upper air outlet frame; a filter frame bolted to one side of the surface of the lower fan frame and the upper air outlet frame; one side of the fan blade connected to the output end of the motor; and a filter screen installed inside the filter frame.

[0008] Preferably, the radial length of the partition plate is less than the radial length of the galvanized keel layer and the rock wool insulation layer, the size of the lower fan frame is aligned with the lower closed structure of the partition plate, and the upper air outlet frame is aligned with the upper closed structure of the partition plate.

[0012] Preferably, the air outlet is designed with a slope in the upper air outlet frame, and the slope angle is five percent.

[0013] Compared with related technologies, the thermal insulation structure for the heat transfer pump room provided by this utility model has the following beneficial effects: The device constructs an air-insulated interlayer supported by galvanized steel framing on the side of the concrete wall, and fills the interlayer with a high-performance rock wool insulation layer, forming a multi-layered thermal insulation structure. It is equipped with a forced ventilation system that supplies air from the bottom and exhausts it from the top, enabling continuous air circulation within the interlayer.

The rock wool layer effectively inhibits conductive and radiative heat transfer, and the air-insulated interlayer blocks thermal bridging. This structure significantly reduces the heat flux density of the wall, increases the total thermal resistance, and slows down the wall temperature rise, keeping the internal temperature of the electrical distribution room within a safe range. This improves the operational safety of electrical equipment, extends its service life, and achieves both active heat dissipation and passive insulation. Attached Figure Description

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] A preferred embodiment of the heat insulation structure for the heat medium pump room provided by this utility model is, for example... Figures 1 to 5 As shown: A heat transfer pump room insulation structure includes: a concrete floor 1; a concrete wall 2 integrally cast on the concrete floor 1; a galvanized keel layer 3 installed on the concrete floor 1; a rock wool insulation layer 4 covering both sides of the galvanized keel layer 3; a partition plate 5 extending on the side walls of the galvanized keel layer 3 and the rock wool insulation layer 4; and a ventilation component 6 assembled along the closed structure of the concrete floor 1, the concrete wall 2, the galvanized keel layer 3 and the rock wool insulation layer 4.

[0019] In this embodiment, when the system is started, the motor 608 in the ventilation assembly 6 drives the fan blades 603 inside the lower fan frame 601 to rotate synchronously. After being filtered by the filter frame 607 and the filter screen 609, the external air enters the device through the air inlet of the lower fan frame 601. The airflow first flows upward along the air gap formed between the galvanized keel layer 3 and the concrete wall 2. During this process, it forms a large-area contact with the outer surface of the concrete wall 2 and continuously absorbs the heat conducted from the wall surface through convection heat transfer. The airflow is guided upward along the partition plate 5 in the confined space and enters the upper exhaust area through the channel connecting the connecting plate 602 and the upper air outlet frame 604. The upper air outlet frame 604 is provided with a sloped air guide plate 606. The inclination angle of the sloped air guide plate 606 causes the airflow to form a directional guiding effect at the air outlet 605, which promotes the airflow to flow smoothly. The system effectively removes and prevents the backflow of hot air from the outside. Simultaneously, the sloped structure of the upper exhaust frame 604 creates a natural draft effect, further enhancing the overall airflow circulation efficiency. The airflow within the entire air gap forms a closed-loop ventilation channel from bottom to top. Driven continuously by the fan blades 603, a stable airflow speed is maintained, continuously carrying away heat from the wall and discharging it to the outside, achieving active heat dissipation and reducing the temperature gradient. Meanwhile, the rock wool insulation layer 4 covers both sides of the galvanized keel layer 3, providing efficient heat conduction inhibition and radiation reflection, making it difficult for heat from the heat medium pump room to diffuse through the wall to the electrical distribution room. Through multiple sets of composite thermal resistance systems, the device achieves coordinated control of the three heat transfer paths: conduction, radiation, and convection, effectively increasing the total thermal resistance of the wall and maintaining the internal ambient temperature of the electrical distribution room within a safe operating range.

[0020] In a further preferred embodiment of this utility model, the other side of the partition plate 5 is connected to the concrete wall 2, and the galvanized keel layer 3 and the rock wool insulation layer 4 are arranged parallel to each other with the concrete wall 2.

[0021] In this embodiment, by connecting the partition plate 5 to the concrete wall 2 and setting the galvanized keel layer 3 and the rock wool insulation layer 4 parallel to the wall, a stable multi-layer thermal insulation structure is formed, ensuring that the thickness of the air interlayer is uniform and providing a reliable structural foundation for airflow channels and heat blocking.

[0022] In a further preferred embodiment of this utility model, the ventilation component 6 includes: a lower fan frame 601 bolted to the lower side of the edge of a closed structure formed by a concrete floor 1, a concrete wall 2, a galvanized keel layer 3, and a rock wool insulation layer 4; a connecting plate 602 installed on the top surface of the lower fan frame 601; a fan blade 603 installed inside the lower fan frame 601; an upper air outlet frame 604 fixedly connected to the upper side of the connecting plate 602; an air outlet 605 opened inside the upper air outlet frame 604; a sloped air guide plate 606 fixedly connected to the lower side of the inner edge of the upper air outlet frame 604; a filter frame 607 bolted to one side of the surface of the lower fan frame 601 and the upper air outlet frame 604; one side of the fan blade 603 connected to the output end of the motor 608; and a filter screen 609 installed inside the filter frame 607.

[0023] In this embodiment, the ventilation unit plays a core role in active heat dissipation and airflow circulation. During operation, the motor 608 starts, driving the fan blades 603 inside the lower fan frame 601 to rotate at high speed, forming a stable upward airflow. External air, filtered by the filter frame 607 and filter screen 609, enters the lower fan frame 601 and is accelerated into the air gap between the galvanized keel layer 3 and the concrete wall 2. During its flow, the airflow continuously absorbs heat conducted from the wall surface and is guided upwards along the partition plate 5, passing through the connecting plate 602 and entering the upper air outlet frame 604. The sloped air guide plate 606 inside the upper air outlet frame 604 evenly distributes the airflow and guides it to the air outlet 605 for discharge, achieving continuous convection circulation from bottom to top. This structure utilizes the combined effect of forced convection and natural draft to continuously remove high-temperature heat from one side of the heat medium pump room, significantly reducing the wall's heat transfer rate and heat flux density, achieving efficient heat insulation and active heat dissipation.

[0024] In a further preferred embodiment of this utility model, the radial length of the partition plate 5 is less than the radial length of the galvanized keel layer 3 and the rock wool insulation layer 4, the size of the lower fan frame 601 is aligned with the lower closed structure of the partition plate 5, and the upper air outlet frame 604 is aligned with the upper closed structure of the partition plate 5.

[0025] In this embodiment, by aligning the lower fan frame 601 with the lower structure of the partition plate 5 and the upper air outlet frame 604 with the upper structure, the airflow channel is ensured to be vertically continuous and the path is smooth, effectively avoiding eddies or air leakage, and improving the consistency and stability of ventilation and heat conduction.

[0026] In a further preferred embodiment of this utility model, the upper edge of the slope guide plate 606 is aligned with the lower edge of the air outlet 605, and the connecting plate 602 is aligned with the partition plate 5.

[0027] In this embodiment, the sloped air guide plate 606 is positioned corresponding to the air outlet 605, which can guide the airflow to be smoothly discharged along the tilt direction, prevent hot air backflow, enhance the natural draft effect, and thus improve the heat dissipation uniformity and exhaust efficiency.

[0028] In a further preferred embodiment of this utility model, two sets of filter screens 609 are provided, and the two sets of filter screens 609 are respectively matched with the inlet and outlet side apertures of the lower fan frame 601 and the upper air outlet frame 604.

[0029] In this embodiment, two sets of filters 609 are matched with the inlet and outlet side apertures respectively to achieve bidirectional filtration, effectively blocking dust and impurities from entering the channel, ensuring clean air circulation and stable operation of the fan, and extending the service life of the system.

[0030] In a further preferred embodiment of the present invention, the fan blade 603 is synchronously rotated by the motor 608, and the main body of the motor 608 is supported inside the lower fan frame 601.

[0031] In this embodiment, the fan blade 603 is driven to rotate synchronously by the motor 608 to form a continuous and stable forced air supply. The motor 608 is built into the lower fan frame 601 and is driven by an external electronic control system, which reduces vibration and noise and improves drive reliability, providing continuous power support for the system.

[0032] In a further preferred embodiment of this utility model, the air outlet 605 is designed with a slope in the upper air outlet frame 604, and the slope angle is five percent.

[0033] In this embodiment, the air outlet 605 inside the upper air outlet frame 604 is set with a 5% slope, which uses gravity and airflow inertia to form a guiding and exhaust effect, avoiding backflow of condensate or rainwater, ensuring smooth heat dissipation and stable protective performance of the upper structure.

[0034] In summary, the device uses motor 608 to drive fan blades 603 to form a forced convection airflow that enters from the bottom and exits from the top. After being filtered by filter screen 609, the external air enters the air gap between galvanized keel layer 3 and concrete wall 2, absorbs heat conducted by the wall, and is then discharged through the top air outlet frame 604. Rock wool insulation layer 4 blocks heat conduction, and air gap weakens radiation, forming a composite system of active heat dissipation and passive heat insulation, thereby achieving wall cooling and stable temperature in the power distribution room.
