Description

Technical Field

[0001] This utility model relates to the field of cooler technology, and in particular to a dual-tube air cooler. Background Technology

[0002] The dual-tube air cooler is a new type of cooling equipment designed for "high-efficiency heat exchange + compact space adaptation". Its core principle is to achieve high-efficiency heat exchange between the medium to be cooled and the air through the "inner tube-outer tube" double-layer tube structure. The medium to be cooled flows inside the tube, and the air is forced to convect in the gap between the two tubes or outside the tube. The double-layer tube expands the heat exchange area and optimizes the flow field distribution.

[0003] Adjust the distance between the two mounting blocks according to the distance between the two mounting holes at the same level to accommodate more installation positions, and then quickly install the inner tube extension end to reduce the number of inner tube connections.

[0004] Most existing dual-tube air coolers directly connect the inner tube to the external pre-installed pipe. During long-term use, repeated disassembly and reassembly will damage the connection end of the inner tube, requiring the replacement of the entire cooling component, which increases the cost of use. At the same time, it is not convenient to install the cooling component according to the mounting hole position. Therefore, a dual-tube air cooler is proposed. Utility Model Content

A top rod adapted to the support frame is symmetrically installed on one side of the pull ring. L-shaped locking blocks adapted to the inner tube are symmetrically installed on the outer surface of the connecting pipe. An adjustment mechanism is symmetrically arranged inside the support frame. The adjustment mechanism includes an L-shaped slider movably installed inside the support frame. A second mounting block is installed on the top of the L-shaped slider. A first mounting block adapted to the second mounting block is installed on the outer surface of the support frame. A concave slider is movably installed inside the L-shaped slider. A push plate is provided on the top of the concave slider.

[0007] As a preferred embodiment of the dual-tube air cooler of this utility model, the inner tube connection end is provided with symmetrically arranged opening slots on one side for use with the L-shaped locking block, the L-shaped locking block is movably inserted into the opening slot, and the L-shaped locking block is movably locked into the inner side of the inner tube connection end. The second fixing ring is provided with symmetrically arranged sliding holes for use with the top rod on one side, and the top rod is slidably connected to the sliding holes.

[0008] In a preferred embodiment of the dual-tube air cooler described in this utility model, the pull ring is slidably connected to the outside of the connecting tube, a first spring is installed on one side of the pull ring, and a first fixing ring is provided on one side of the first spring.

[0009] In a preferred embodiment of the dual-tube air cooler of this utility model, the first fixing ring and the second fixing ring are both fixedly sleeved on the outside of the connecting pipe, the first spring is located on the outside of the connecting pipe, and the support frame has symmetrical slots on one side adapted to the top rod, and the top rod is movably inserted into the slot.

[0010] In a preferred embodiment of the dual-tube air cooler of this utility model, a groove adapted to the L-shaped slider is provided on one side of the support frame, the L-shaped slider is slidably connected inside the groove, a limiting groove adapted to the concave slider is provided on the top of the L-shaped slider, the concave slider is slidably connected inside the limiting groove, a plurality of second springs are evenly distributed on one side of the concave slider, and top pins are symmetrically installed on one side of the push plate.

[0011] In a preferred embodiment of the dual-tube air cooler of this utility model, slide rods adapted to the L-shaped slider are symmetrically installed on the bottom of the inner surface of the slide groove. A plurality of circular grooves adapted to the top pin are evenly distributed on one side of the inner surface of the slide groove. The top pin is movably engaged in the circular groove. Grooves adapted to the slide rod are symmetrically opened on the bottom of the L-shaped slider. The L-shaped slider is slidably connected to the outside of the slide rod through the groove.

[0012] This invention provides a dual-tube air cooler. It has the following advantages: 1. By using a conversion mechanism, the connection end of the inner tube is extended, reducing the number of connections and protecting the connection end. The sealing ring is placed on the opposite side of the inner tube and the connecting tube. The connecting tube is then attached to the inner tube. During this attachment process, an L-shaped locking block is passed through the opening slot of the inner tube, and a 90-degree rotational force is applied to the connecting tube, causing the two L-shaped locking blocks to rotate. Under the action of the first spring, a pushing force is applied to the pull ring, which pushes the two push rods into the corresponding slots of the support frame, fixing the connecting tube and preventing it from rotating. This protects the connection end of the inner tube, reduces the number of connections, and avoids damage to the connection end requiring replacement of the condenser components, thus preventing resource waste.

Through the adjustment mechanism, the distance between the second mounting block and the first mounting block can be adjusted according to the position of the mounting holes of the support frame, so that the support frame can be quickly installed in the required position. Pushing the push plate towards the second mounting block causes the two top pins to move out of the corresponding circular grooves, and applying a pushing force towards the first mounting block to the push plate causes its L-shaped slider to move towards the first mounting block in the support frame, adjusting the distance between the second mounting block and the first mounting block to adapt to different mounting hole spacings, so as to facilitate the rapid installation of the support frame and improve the installation efficiency of the support frame.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0022] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a dual-tube air cooler, comprising: Support frame 1, with an inner tube 4 installed inside the support frame 1 and an outer tube 5 provided on the outer surface of the inner tube 4; The conversion mechanism 2 is located at both ends of the inner tube 4. The conversion mechanism 2 includes a connecting pipe 201 located on one side of the connecting end of the inner tube 4. A sealing ring 202 is provided on the side of the connecting pipe 201 opposite to the inner tube 4. A second fixing ring 208 is installed on the outer surface of the connecting pipe 201. A pull ring 206 is provided on one side of the second fixing ring 208. A top rod 207 adapted to the support frame 1 is symmetrically installed on one side of the pull ring 206. An L-shaped locking block 203 adapted to the inner tube 4 is symmetrically installed on the outer surface of the connecting pipe 201.

[0023] like Figure 2 and Figure 3 As shown, in this embodiment, an opening slot adapted to the L-shaped locking block 203 is symmetrically opened on one side of the inner tube 4 connecting end. The L-shaped locking block 203 is movably inserted into the opening slot and is movably locked inside the inner tube 4 connecting end. A sliding hole adapted to the top rod 207 is symmetrically opened on one side of the second fixing ring 208. The top rod 207 is slidably connected inside the sliding hole. Under the action of the two L-shaped locking blocks 203, the connecting tube 201 drives the two L-shaped locking blocks 203 to pass through the opening slot and apply rotational force to the connecting tube 201, so that the L-shaped locking blocks 203 are locked inside the inner tube 4 connecting end. With the assistance of the second fixing ring 208, both top rods 207 are inserted into the support frame 1, so that the connecting tube 201 is connected to the inner tube 4, reducing the number of connections of the inner tube 4 connecting end and preventing damage to the inner tube 4 connecting end due to excessive connection.

[0024] like Figure 3As shown, in this embodiment, the pull ring 206 is slidably connected to the outside of the connecting pipe 201. A first spring 204 is installed on one side of the pull ring 206, and a first fixing ring 205 is provided on one side of the first spring 204. Under the action of the first spring 204, a pushing force is always applied to the pull ring 206 in the direction of the support frame 1, so that the pull ring 206 is always in contact with the side of the second fixing ring 208, and the push rod 207 is always kept in the extended state.

[0025] like Figure 3 As shown, in this embodiment, the first fixing ring 205 and the second fixing ring 208 are both fixedly sleeved on the outside of the connecting pipe 201. The first spring 204 is located on the outside of the connecting pipe 201. The support frame 1 has symmetrical slots on one side that are adapted to the top rod 207. The top rod 207 is movably inserted into the slot. Under the action of the two top rods 207, they are inserted into the corresponding slots to prevent the connecting pipe 201 from rotating on the inner pipe 4 side, so that the L-shaped locking block 203 is stably locked inside the inner pipe 4.

[0026] Further, align the connecting tube 201 with the connecting end of the inner tube 4, place the sealing ring 202 on the opposite side of the connecting tube 201 and the inner tube 4, and during the process of fitting the connecting tube 201 towards the inner tube 4, pass the two L-shaped locking blocks 203 through the corresponding opening slots of the inner tube 4. At this time, the two push rods 207 are in a horizontal state. Manually push the pull ring 206 towards the other end of the connecting tube 201. The pull ring 206 compresses and deforms the first spring 204, and the pull ring 206 drives the push rod 207 to the second fixing ring 208. During the movement, a 90-degree rotational force is applied to the connecting pipe 201 via the pull ring 206. The connecting pipe 201 drives the two L-shaped locking blocks 203 to rotate, causing the L-shaped locking blocks 203 to lock inside the connecting end of the inner pipe 4. At this time, the two push rods 207 are in a vertical state. The force applied to the pull ring 206 is removed, and under the action of the first spring 204, a pushing force is applied to the pull ring 206 in the opposite direction to the support frame 1. The pull ring 206 pushes the two push rods 207 into the corresponding slots of the support frame 1, thus completing the connection of the extension end of the inner pipe 4. Example

[0027] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The adjustment mechanism 3 is symmetrically arranged inside the support frame 1. The adjustment mechanism 3 includes an L-shaped slider 302 that is movably installed inside the support frame 1. A second mounting block 303 is installed on the top of the L-shaped slider 302. A first mounting block 301 that is adapted to the second mounting block 303 is installed on the outer surface of the support frame 1. A concave slider 305 is movably installed inside the L-shaped slider 302. A push plate 306 is provided on the top of the concave slider 305.

[0028] like Figure 4As shown, in this embodiment, a groove adapted to the L-shaped slider 302 is provided on one side of the support frame 1. The L-shaped slider 302 is slidably connected inside the groove. A limiting groove adapted to the concave slider 305 is provided on the top of the L-shaped slider 302. The concave slider 305 is slidably connected inside the limiting groove. Multiple second springs 304 are evenly distributed on one side of the concave slider 305. Top pins 307 are symmetrically installed on one side of the push plate 306. When the L-shaped slider 302 moves in the groove of the support frame 1, it drives the second mounting block 303 to move. By adjusting the distance between the second mounting block 303 and the first mounting block 301, it can be adapted to the distance of different mounting holes.

[0029] like Figure 5 As shown, in this embodiment, slide rods 308 adapted to the L-shaped slider 302 are symmetrically installed on the bottom of the inner surface of the slide groove. Several circular grooves adapted to the top pin 307 are evenly distributed on one side of the inner surface of the slide groove. The top pin 307 is movably engaged in the circular groove. The bottom of the L-shaped slider 302 is symmetrically provided with grooves adapted to the slide rod 308. The L-shaped slider 302 is slidably connected to the outside of the slide rod 308 through the grooves. Under the action of the slide rod 308, the L-shaped slider 302 is prevented from rotating during movement and its rotation is restricted. At the same time, the L-shaped slider 302 is fixed in this position, allowing only the L-shaped slider 302 to move laterally in this position. Through the action of the top pin 307, the second mounting block 303 can be fixed in the adjusted position.

[0030] Furthermore, based on the distance between the mounting holes, the distance between the second mounting block 303 and the first mounting block 301 is adjusted. At this time, the push plate 306 is manually pushed towards the second mounting block 303. The push plate 306 drives the concave slider 305 to move within the L-shaped slider 302. The concave slider 305 compresses and deforms against the multiple second springs 304. The push plate 306 drives the two top pins 307 to move out of the corresponding circular grooves in the support frame 1, applying a pushing force towards the first mounting block 301 to the push plate 306. With the assistance of the two sliding rods 308, the push plate 306 drives the L-shaped slider 302 via the concave slider 305. Block 302 moves in the opposite direction to the first mounting block 301. The L-shaped slider 302 drives the second mounting block 303 to move. After the distance between the second mounting block 303 and the first mounting block 301 is adjusted, the thrust applied to the push plate 306 is removed. Under the action of multiple second springs 304, a reverse thrust is applied to the concave slider 305, causing the push plate 306 to drive the top pin 307 to engage in the corresponding circular groove. The second mounting block 303 and the first mounting block 301 on the opposite side are adjusted using the above method. The second mounting block 303 and the first mounting block 301 are then fixed against the mounting hole side with bolts.

[0031] Working principle: First, adjust the distance between the second mounting block 303 and the first mounting block 301 according to the distance between the mounting holes. Then, manually push the push plate 306 towards the second mounting block 303. The push plate 306 drives the concave slider 305 to move in the L-shaped slider 302. The concave slider 305 compresses and deforms the multiple second springs 304. The push plate 306 drives the two top pins 307 to move out of the corresponding circular grooves in the support frame 1, applying a pushing force towards the first mounting block 301 to the push plate 306. With the assistance of the two slide rods 308, the push plate 306 drives the L-shaped slider 302 through the concave slider 305. The slider 302 moves in the opposite direction to the first mounting block 301, causing the L-shaped slider 302 to move the second mounting block 303. After adjusting the distance between the second mounting block 303 and the first mounting block 301, the thrust applied to the push plate 306 is removed. Under the action of multiple second springs 304, a reverse thrust is applied to the concave slider 305, causing the push plate 306 to drive the top pin 307 into the corresponding circular groove. Using the above method, the second mounting block 303 and the first mounting block 301 on the opposite side are adjusted. The second mounting block 303 and the first mounting block 301 are then fixed against the mounting hole side with bolts. After the support frame 1 is fixed, connect the extension end of the inner tube 4. At this time, align the connecting pipe 201 with the connecting end of the inner tube 4, place the sealing ring 202 on the opposite side of the connecting pipe 201 and the inner tube 4, and during the process of fitting the connecting pipe 201 towards the inner tube 4, pass the two L-shaped locking blocks 203 through the corresponding opening slots of the inner tube 4. At this time, the two push rods 207 are in a horizontal state. Manually push the pull ring 206 towards the other end of the connecting pipe 201. The pull ring 206 compresses and deforms the first spring 204. The pull ring 206 drives the push rod 207 to move in the second fixing ring 208. Apply a 90-degree rotational force to the connecting pipe 201. The connecting pipe 201 drives the two L-shaped locking blocks 203 to rotate, so that the L-shaped locking blocks 203 are locked inside the connecting end of the inner pipe 4. At this time, the two push rods 207 are in a vertical state. Remove the force applied to the pull ring 206. Under the action of the first spring 204, apply a push force to the pull ring 206 in the opposite direction to the support frame 1. The pull ring 206 pushes the two push rods 207 into the corresponding slots of the support frame 1, thus completing the connection of the extension end of the inner pipe 4. Finally, connect the external preset pipe to the two connecting pipes 201, and then connect the cold air pipe to both ends of the outer pipe 5 for use.
