Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and in particular relates to an internal finned tube heat exchanger which is easy to install. Background Art

[0002] Existing air-cooled heat exchangers mostly use vertically arranged fans to achieve rapid heat dissipation. The vertical airflow generated by the fan can quickly dissipate the heat inside the device from the inside of the device. However, existing fan grilles mostly adopt a fixed design. When plastic bags and other debris move to the top of the grille under the guidance of the airflow, they are easy to cover the surface of the grille, thereby affecting the normal flow of the airflow, reducing the air flow speed per unit time, and affecting the working efficiency of the device. For this reason, we propose an easy-to-install internal fin tube heat exchanger to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide an internal finned tube heat exchanger that is easy to install, so as to solve the problem raised in the above background technology that when plastic bags and other debris move to the top of the mesh cover under the guidance of the airflow, they are easy to cover the surface of the mesh cover, thereby affecting the normal flow of the airflow, reducing the air flow speed per unit time, and affecting the working efficiency of the device.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an internal finned tube heat exchanger that is easy to install, comprising a heat exchanger body, a fan and a protective mesh cover, a fan is welded to the top of the heat exchanger body, and a protective mesh cover is sleeved on the inner upper end of the fan, four groups of setting grooves are evenly spaced inside the fan, and the inner lower ends of the four groups of setting grooves are all welded with limiting blocks, the inner parts of the four groups of limiting blocks are all sleeved with sliding rods, and the outer upper ends of the four groups of sliding rods are all sleeved with a first spring, a touch switch is fixedly installed on the inner lower end of the setting groove on one side by screws, and a V-shaped radiator is fixedly installed on the inner part of the heat exchanger body by screws.

[0005] Preferably, the sliding rod is designed in a "T" shape, and the bottom end of the transverse part of the sliding rod is fixedly connected to the top end of the first spring by welding, and the bottom end of the first spring is fixedly connected to the top end of the limit block by welding.

[0006] Preferably, the distance between the bottom end of the horizontal portion of the sliding rod and the top end of the limit block is equal to the distance between the bottom end of the vertical portion of the sliding rod and the touch switch.

[0007] Preferably, the output end of the touch switch is fixedly connected to the input end of the V-shaped radiator through a wire, and the input end of the touch switch is electrically connected to an external power supply through a wire.

[0008] Preferably, an auxiliary limiting device is provided at the top of the fan, and the auxiliary limiting device includes a fixed rod, a transmission rod, a rubber connector, a movable groove and a setting rod. Four groups of fixed rods are welded at equal intervals on the top of the fan, and the outside of the fixed rods are all sleeved with transmission rods, one end of the inside of the transmission rod is provided with a movable groove, and the inside of the movable groove is sleeved with a setting rod, the bottom end of the setting rod is glued with a rubber connector, and the outside of the lower end of the setting rod is sleeved with a second spring.

[0011] Preferably, the four groups of fixing rods correspond one-to-one to the four groups of setting grooves respectively.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The adjustable and controllable heat exchanger cooperates with the limit block, the sliding rod, the first spring, the touch switch and the fixed rod. When plastic bags and other debris cover the outer surface of the protective mesh cover, the protective mesh cover tends to move downward under the action of the airflow, so that the sliding rod can trigger the touch switch to connect the circuit, so that the fixed rod sends an alarm to remind the staff to deal with it. This avoids the problem that when the existing heat exchanger encounters plastic bags and other debris moving to the top of the mesh cover under the guidance of the airflow, it is easy to cover the surface of the mesh cover, thereby affecting the normal flow of the airflow, reducing the air flow speed per unit time, and affecting the working efficiency of the device, thereby improving the ease of use of the device.

[0014] (2) The adjustable and controllable heat exchanger cooperates with the transmission rod, the rubber connector, the movable groove, the setting rod and the second spring. When the protective mesh cover is set inside the setting groove, the rubber connector and the setting rod can limit the protective mesh cover under the elastic force of the second spring. This structure is easy to install and disassemble, thereby avoiding the existing bolt fixing method that is prone to rust after long-term use, thereby affecting the normal disassembly and maintenance of the protective mesh cover, and further improving the ease of use of the device.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 The utility model provides a technical solution: an internal finned tube heat exchanger that is easy to install, comprising a heat exchanger body 1, a fan 2 and a protective mesh cover 3, the fan 2 is welded on the top of the heat exchanger body 1, and the protective mesh cover 3 is sleeved on the upper end of the inner part of the fan 2, four groups of setting grooves 4 are opened at equal intervals inside the fan 2, and the lower ends of the inner parts of the four groups of setting grooves 4 are all welded with limiting blocks 5, the inner parts of the four groups of limiting blocks 5 are all sleeved with sliding rods 6, and the upper ends of the outer parts of the four groups of sliding rods 6 are all sleeved with first springs 7, a touch switch 8 is fixedly installed on the lower end of the inner part of the setting groove 4 on one side by screws, and a V-shaped radiator 15 is fixedly installed on the inner part of the heat exchanger body 1 by screws.

[0023] In the present embodiment, preferably, the sliding rod 6 is designed in a "T" shape, and the bottom end of the transverse part of the sliding rod 6 is fixedly connected to the top end of the first spring 7 by welding, and the bottom end of the first spring 7 is fixedly connected to the top end of the limit block 5 by welding. Through this design, under the limiting action of the limit block 5 and the first spring 7, the sliding rod 6 can always maintain a relatively stable setting state, so that the sliding rod 6 can play a role in stabilizing the support of the protective net cover 3, thereby improving the stability of the device.

[0024] In this embodiment, preferably, the distance between the bottom end of the horizontal part of the sliding rod 6 and the top end of the limit block 5 is equal to the distance between the bottom end of the vertical part of the sliding rod 6 and the touch switch 8. Through this design, when the bottom end of the horizontal part of the sliding rod 6 and the top end of the limit block 5 contact each other, the sliding rod 6 can just trigger the touch switch 8 to make the touch switch 8 work, avoiding the problem of damage to the touch switch 8 caused by excessive movement of the sliding rod 6, thereby improving the safety of the device.

[0025] In this embodiment, preferably, the output end of the touch switch 8 is fixedly connected to the input end of the V-shaped radiator 15 through a wire, and the input end of the touch switch 8 is electrically connected to the external power supply through a wire. This design can ensure the normal operation of each electrical appliance.

[0026] In the present embodiment, preferably, an auxiliary limiting device is provided at the top of the fan 2, and the auxiliary limiting device includes a fixed rod 9, a transmission rod 10, a rubber connector 11, a movable groove 12 and a setting rod 13. Four groups of fixed rods 9 are welded at equal intervals on the top of the fan 2, and the outside of the fixed rods 9 are all sleeved with transmission rods 10, one end of the inside of the transmission rods 10 is opened with a movable groove 12, and the inside of the movable groove 12 is all sleeved with a setting rod 13, the bottom end of the setting rod 13 is glued with a rubber connector 11, and the lower end of the setting rod 13 is sleeved with a second spring 14.

[0027] In this embodiment, preferably, the movable groove 12 is designed in an "I" shape, and the bottom end of the movable groove 12 is sleeved on the outside of the second spring 14. Through this design, the movable groove 12 can provide a storage space for the normal contraction of the setting rod 13 and the second spring 14, thereby ensuring that the setting rod 13 can be moved out from the inside of the setting groove 4 by being embedded in the movable groove 12, thereby ensuring the normal use of the device.

[0028] In this embodiment, preferably, the cross-section of the transmission rod 10 is designed in an "8" shape, and the length of the transmission rod 10 is greater than the distance between the fixed rod 9 and the setting groove 4. Through this design, when the transmission rod 10 rotates under the action of thrust, the transmission rod 10 can stably drive the setting rod 13 to move the setting rod 13 to the upper end of the setting groove 4, thereby ensuring the normal use of the device.

[0029] In this embodiment, preferably, the four groups of fixing rods 9 correspond one-to-one to the four groups of setting grooves 4 respectively. This design can ensure that the transmission rod 10 accurately corresponds to the setting groove 4 under the limiting action of the fixing rod 9, thereby ensuring that the setting rod 13 can be stably moved to the inside of the setting groove 4 driven by the transmission rod 10.

[0030] The working principle and use process of the utility model are as follows: when in use, the protective mesh cover 3 is first sleeved inside the fan 2 and the extended part at the edge of the setting groove 4 is sleeved inside the four groups of setting grooves 4 in sequence. When the protective mesh cover 3 and the top end of the sliding rod 6 are in contact with each other, the transmission rod 10 is rotated to rotate the transmission rod 10 around the fixed rod 9. During the rotation process, the transmission rod 10 drives the setting rod 13 to move the setting rod 13 to the top of the setting groove 4. The second spring 14 returns to its initial shape. Under the action of the elastic force of the second spring 14, the setting rod 13 moves vertically downward along the movable groove 12 and is embedded in the inside of the setting groove 4. The rubber connector 11 is pushed by the setting rod 13 to contact the protective mesh cover 3 and plays a role in limiting the protective mesh cover 3.

[0031] When plastic bags and other debris cover the outer surface of the protective mesh cover 3, the protective mesh cover 3 tends to move downward under the action of airflow. During the movement, the protective mesh cover 3 drives the sliding rod 6 to move vertically downward along the limit block 5. The first spring 7 contracts and accumulates force under the push of the protective mesh cover 3. When the bottom end of the sliding rod 6 contacts the touch switch 8 during the movement, the sliding rod 6 triggers the touch switch 8. The touch switch 8 connects the circuit to enable the external power supply to supply power to the V-shaped radiator 15. When the plastic bag is removed, the airflow returns to normal, the first spring 7 returns to its initial shape, and under the action of the elastic force of the first spring 7, the sliding rod 6 pushes the protective mesh cover 3 to move the protective mesh cover 3 to its initial position, and the operation ends here.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
