Description

Technical Field

[0001] This utility model relates to heating radiators, and more particularly to a multi-cavity composite convection heating radiator. Background Technology

[0002] Heating radiators use a heat exchange process where a heat medium passes through pipes and releases heat to raise the temperature of the surrounding environment and achieve the purpose of heating. In order to increase the heat exchange area and the heat exchange time of the heat medium, the water circuit is generally set in an S-shape.

[0003] Although the S-shaped water passage increases the time for the heat medium to pass through and the heat exchange time, in actual use, the water flow encounters greater resistance when it reaches the bend. If the water flow rate is small, this resistance has a smaller impact. However, if the water pressure is high, it can easily lead to severe turbulence and cavitation when the high-pressure, high-speed water flow impacts the bend. This not only generates noise but also causes corrosion damage to the pipe wall at the bend over a long period of time. Utility Model Content

[0004] This invention addresses the problem that existing drill bits, being of integral structure, cannot be replaced individually when partial damage occurs. The technical problem this invention aims to solve is to provide a multi-cavity composite convection heating radiator.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A multi-cavity composite convection heating radiator includes a frame, on which are provided an upper horizontal pipe, a lower horizontal pipe, and several vertical pipes connecting the two horizontal pipes. Each of the upper and lower horizontal pipes is provided with at least one pressure relief valve. The pressure relief valves form an isolation to make the internal pipes form an alternating "S" shaped water circuit. The trigger pressure of the pressure relief valve in the upper horizontal pipe is less than the trigger pressure of the pressure relief valve in the lower horizontal pipe.

[0006] Preferably, a pressure relief valve is provided in both the upper and lower horizontal pipes, and a plug is provided at the tail end of the lower horizontal pipe. The plug blocks the water passage, allowing the low-pressure heat medium to circulate twice in the vertical pipe.

[0007] Preferably, the two vertical pipes are grouped together, and the pressure relief valve is located between each group.

[0008] Preferably, the pressure relief valve includes a valve seat, a connecting frame with a through hole, and a valve core. The valve core is slidably disposed on the connecting frame, and the connecting frame is provided with an elastic component. The elastic component applies an elastic force to the valve core, causing the valve core to abut against the valve seat to form a seal.

[0009] Preferably, the connecting frame includes several connecting pipes and a cylindrical cylinder disposed at the inner end of the connecting pipes. The cylindrical cylinder is connected to the inner wall of the upper horizontal pipe and the lower horizontal pipe through the connecting pipes, and the valve core is slidably disposed inside the cylindrical cylinder.

[0010] Preferably, the valve core includes a piston head disposed on the cylindrical cylinder, a piston rod disposed on the piston head, and a sealing head slidably sleeved on the piston rod. The elastic component includes gas enclosed in the cylindrical cylinder and a spring sleeved on the piston rod, with the spring applying elastic force to the sealing head.

[0011] Preferably, the lower and upper horizontal tubes are provided with mounting holes that communicate with one of the connecting tubes. An air nozzle is installed at the mounting hole, and the connecting tube communicates with the inside of the cylindrical cylinder, so that the pressure can be adjusted by regulating the gas inside the cylindrical cylinder through the air nozzle.

[0012] Compared with the prior art, the present invention has the following advantages: When the flow rate is low, the water pressure is insufficient to open the bypass valve, and all water flows through the S-shaped water path in a regular manner, ensuring sufficient heat exchange time and guaranteeing heat exchange efficiency; when the flow rate is high, the bypass valve opens, prioritizing the smooth circulation of the system and avoiding excessive resistance. At this time, although the flow time of water flowing through the heat exchanger is slightly shortened, the total heat exchange is still guaranteed by the huge flow rate. Attached Figure Description

Detailed Implementation

[0015] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0016] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0017] This embodiment mainly describes the title of a multi-cavity composite convection heating radiator, as follows: like Figure 1-4 As shown, a multi-cavity composite convection heating radiator includes a frame 10. The frame 10 is provided with an upper horizontal pipe 30, a lower horizontal pipe 20, and several vertical pipes 60 connecting the two horizontal pipes. Each of the upper horizontal pipe 30 and the lower horizontal pipe 20 is provided with at least one pressure relief valve 50. The pressure relief valve 50 forms an isolation to make the internal pipes form an alternating "S" shaped water path. The triggering pressure of the pressure relief valve 50 in the upper horizontal pipe 30 is less than the triggering pressure of the pressure relief valve 50 in the lower horizontal pipe 20. This solution ensures that at low flow rates, the water pressure is insufficient to open the bypass valve, and all water flows through the S-shaped water path, guaranteeing sufficient heat exchange time and efficiency. At high flow rates, the bypass valve opens to prioritize smooth system circulation and avoid excessive resistance. Although the flow time of water passing through the heat exchanger is slightly shortened at this time, the total heat exchange is still guaranteed by the large flow rate. In addition, this embodiment adopts a bottom-inlet and bottom-outlet structure, so setting the opening pressure of the lower pressure relief valve 50 to be greater than that of the upper one can ensure that the water flows along the original S-shaped water path as much as possible, while reducing the impact of water flow impact.

[0018] Preferably, a pressure relief valve 50 is provided in both the upper horizontal pipe 30 and the lower horizontal pipe 20, and a plug 40 is provided at the tail side of the lower horizontal pipe 20. The plug 40 blocks the water passage, allowing the low-pressure heat medium to circulate twice in the vertical pipe 60. In this design, the plug 40 is provided to prevent the heat medium overflowing from the lower pressure relief valve 50 from leaving the radiator too quickly, thus avoiding heat waste.

[0019] Preferably, the risers 60 are arranged in groups of two, with the pressure relief valve 50 positioned between each group. When arranged in groups of two, this configuration can accommodate both large and small flow rates of heat transfer media.

[0020] Preferably, the pressure relief valve 50 includes a valve seat, a connecting frame with a through hole, and a valve core. The valve core is slidably mounted on the connecting frame, and the connecting frame is provided with an elastic component. The elastic component applies elastic force to the valve core, causing the valve core to abut against the valve seat to form a seal. Preferably, the connecting frame includes several connecting pipes 501 and a cylindrical cylinder 502 disposed at the inner end of the connecting pipes 501. The cylindrical cylinder 502 is connected to the inner wall of the upper horizontal pipe 30 and the lower horizontal pipe 20 through the connecting pipes 501, and the valve core is slidably mounted inside the cylindrical cylinder 502. Preferably, the valve core includes a piston head 500 disposed on a cylindrical cylinder 502, a piston rod 503 disposed on the piston head 500, and a sealing head 504 slidably sleeved on the piston rod 503. The elastic component includes gas enclosed in the cylindrical cylinder 502 and a spring 505 sleeved on the piston rod 503. The spring 505 applies elastic force to the sealing head 504, wherein the sealing head 504 is provided with a sliding groove, and part of the piston rod 503 extends into the sliding groove. In its natural state, the end of the piston rod 503 has a certain distance from the bottom of the sliding groove. This solution sets up two-stage buffering, provided by the spring 505 and the piston respectively. In the initial stage, the spring 505 and the piston work together. When the piston resistance increases, the spring 505 continues to be compressed. In this process, the two work together to provide sufficient elastic force in the initial state and provide a more gentle recoil movement when subjected to impact, and reduce the risk of failure.

[0021] Preferably, the lower horizontal tube 20 and the upper horizontal tube 30 are provided with mounting holes 301 that communicate with one of the connecting tubes 501. An air nozzle is installed at the mounting hole 301. The connecting tube 501 communicates with the interior of the cylindrical cylinder 502, allowing the pressure to be adjusted by regulating the gas inside the cylindrical cylinder 502 via the air nozzle. This solution provides a function for adjusting support; in cases of spring 505 failure or when the pressure threshold needs adjustment, this can be achieved by adjusting the amount of gas inside the cylindrical cylinder 502.
