Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to an externally mounted dust-proof heat exchanger which is convenient to use. Background Art

[0002] The finned heat exchanger is one of the most widely used heat exchange devices in gas-liquid heat exchangers. At present, most finned heat exchangers are generally installed externally, and the fin pitch between fins is small. When the airflow driven by the air conditioner fan flows through the fins, dust in the air is likely to accumulate on the fins. Long-term dust accumulation will cause blockage between the fins, thus affecting the heat exchange efficiency of the heat exchanger.

[0003] For this reason, the Chinese patent document with the publication number CN218884727U discloses a finned heat exchanger, including a mounting plate, one side of the mounting plate is fixedly connected with a heat exchange frame, and one side of the heat exchange frame is fixedly connected with a base tube. The advantages of the utility model are as follows: First, the staff uses screws to fix the heat exchange frame at the using position through the mounting plate, and then connects the base tube with the compressor. The base tube can generate heat through the heat medium, and the heat can be transferred to the spiral fins. And the heat can be blown out from the spiral fins through an external fan, so as to achieve the purpose of heating the air. Moreover, when the air enters, the dust in the air can be blocked by the dust-proof metal net, thereby preventing dust from entering the interior of the heat exchanger. This not only does not affect the air heating effect of the heat exchanger, but also can achieve the purpose of dust prevention, preventing dust from entering the interior of the heat exchanger and accumulating on the spiral fins.

[0004] In the above technical solution, the installation of the dust-proof frame is mainly fixed through the fixing rods around the dust-proof frame. Therefore, when disassembling and assembling the dust-proof frame, it is necessary to press the control board at the same time so that the fixing rods can be far away from the dust-proof frame before the dust-proof frame can be pressed into the heat exchange frame. Therefore, there is a certain inconvenience in the process of single-person operation, resulting in the overall disassembly and assembly of the dust-proof frame not being convenient enough. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an externally mounted dust-proof heat exchanger which is convenient to use, which can facilitate the overall disassembly and assembly of the dust-proof frame and improve the convenience of use.

[0006] To achieve the above object, the present utility model provides the following technical solution: An externally mounted dust-proof heat exchanger that is convenient to use, comprising a heat exchange frame. One side of the heat exchange frame is provided with a base pipe. A chamber is provided inside the heat exchange frame. A spiral fin is provided inside the chamber. The spiral fin is connected to the base pipe. One side of the heat exchange frame is provided with a slidable dust-proof frame. A dust-proof metal net is fixed inside the dust-proof frame. Fixed rods are provided on both sides of the heat exchange frame. One end of the dust-proof frame is provided with an inclined guiding side wall. A fixing hole is provided above the guiding side wall of the dust-proof frame. The guiding side wall slides to guide the fixed rod into the fixing hole to achieve quick fixation of the dust-proof frame.

[0007] The present utility model is further provided as follows: A guiding pipe is provided outside the heat exchange frame. A sliding seat and a spring are provided inside the guiding pipe. The outer periphery of the sliding seat fits against the inner wall of the guiding pipe. The sliding seat is sleeved and fixed on the outer periphery of the fixed rod. One end of the spring is fixed to the sliding seat and the other end is fixed to the heat exchange frame. One end of the fixed rod extends outside the guiding pipe as a connection end. A lifting handle is provided at the connection end.

[0008] The present utility model is further provided as follows: Sliding grooves are provided inside the heat exchange frame. Both sides of the dust-proof frame are coupled to the sliding grooves and can form a sliding fit therebetween. Sliding grooves are provided inside the heat exchange frame. Both sides of the dust-proof frame are coupled to the sliding grooves and can form a sliding fit therebetween.

[0009] The present utility model is further provided as follows: A lifting groove is provided on the side of the dust-proof frame away from the guiding side wall.

[0010] The present utility model is further provided as follows: A coupling side wall is provided at the bottom of the heat exchange frame. The coupling side wall is adapted to the guiding side wall so that the guiding side wall can fit against the coupling side wall.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] This solution adopts a sliding installation method. When installing the dust-proof frame on the heat exchange frame, by sliding the dust-proof frame downward, since the guiding side wall provided on the dust-proof frame has an increasing distance from the heat exchange frame along the sliding direction, after the guiding side wall contacts the fixed rod, the fixed rod can be gradually compressed. When the fixing hole is opposite to the fixed rod, the fixed rod can be inserted into the fixing hole. In this way, the fixation of the dust-proof frame can be completed only by sliding. Therefore, compared with the fixing method of the dust-proof frame in the prior art, the fixation of the dust-proof frame in this solution is more convenient. So, it effectively solves the technical problem in the prior art that when installing the dust-proof frame, it is necessary to press the control board at the same time, resulting in inconvenient disassembly and assembly of the entire dust-proof frame. Furthermore, by optimizing the installation method of the dust-proof frame, the convenience of disassembly and assembly of the entire dust-proof frame can be improved, which is convenient for overall use.

[0016] Next, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0018] Such as Figures 1 to 3As shown in the figure, the utility model discloses an externally mounted dust-proof heat exchanger which is convenient to use, including a heat exchange frame 1. A base pipe 2 is arranged on one side of the heat exchange frame 1. A chamber 101 is arranged inside the heat exchange frame 1. A spiral fin 9 is arranged inside the chamber 101. The spiral fin 9 is connected to the base pipe 2. A slidable dust-proof frame 3 is arranged on one side of the heat exchange frame 1. A dust-proof metal net 31 is fixed inside the dust-proof frame 3. Fixed rods 4 are arranged on both sides of the heat exchange frame 1. An inclined guiding side wall 32 is arranged at one end of the dust-proof frame 3. A fixing hole 33 is arranged above the guiding side wall 32 of the dust-proof frame 3. The guiding side wall 32 slides to guide the fixed rod 4 to the fixing hole 33, so as to realize the quick fixing of the dust-proof frame 3. When the dust-proof frame 3 is installed on the heat exchange frame 1, by sliding the dust-proof frame 3 downward, due to the guiding side wall 32 arranged on the dust-proof frame 3, the distance between the guiding side wall 32 and the heat exchange frame 1 increases successively along the sliding direction. Thus, after the guiding side wall 32 contacts the fixed rod 4, the fixed rod 4 can be gradually compressed. When the dust-proof frame 3 slides to the position where the fixing hole 33 is opposite to the fixed rod 4, the fixed rod 4 can be inserted into the fixing hole 33. In this way, the fixing of the dust-proof frame 3 can be completed only by sliding. Therefore, compared with the fixing method of the dust-proof frame 3 in the prior art, the fixing of the dust-proof frame 3 in this scheme is more convenient. Furthermore, by optimizing the installation method of the dust-proof frame 3, the convenience of the overall disassembly and assembly of the dust-proof frame 3 can be improved, so as to facilitate the overall use.

[0019] In this embodiment, the structure for the fixed rod 4 to fix the dust-proof frame 3 is that a guiding pipe 5 is arranged outside the heat exchange frame 1. A sliding seat 6 and a spring 7 are arranged inside the guiding pipe 5. The outer periphery of the sliding seat 6 fits against the inner wall of the guiding pipe 5. In this way, the sliding seat 6 can slide smoothly inside the guiding pipe 5. The sliding seat 6 is sleeved and fixed on the outer periphery of the fixed rod 4. One end of the spring 7 is fixed to the sliding seat 6, and one end is fixed to the heat exchange frame 1. One end of the fixed rod 4 extends outside the guiding pipe 5 as a connecting end, and a lifting handle 8 is arranged at the connecting end. When the guiding side wall 32 compresses the fixed rod 4, it can drive the sliding seat 6 to move along the direction away from the fixing hole 33, so as to stretch the spring 7. When the fixing hole 33 is opposite to the fixed rod 4, the stretched spring 7 can reset, so as to drive the fixed rod 4 to be inserted into the fixing hole 33 to realize the fixing of the dust-proof frame 3. Similarly, when the dust-proof frame 3 is disassembled, after pulling the fixed rod 4 out of the fixing hole 33 through the lifting handle 8, the dust-proof frame 3 can be removed by the slidable dust-proof frame 3.

[0020] In this embodiment, a sliding groove 102 is arranged inside the heat exchange frame 1. Both sides of the dust-proof frame 3 are coupled to the sliding groove 102 and can form a sliding fit therebetween. Through the guidance of the sliding groove 102, the sliding path of the dust-proof frame 3 can be guided, ensuring the stability when the dust-proof frame 3 slides.

[0021] In this embodiment, a lifting groove 34 is further provided on the side of the dust-proof frame 3 away from the guiding side wall 32. Through the setting of the lifting groove 34, it is convenient to apply force, so as to facilitate pulling the dust-proof frame 3 to slide, and further improve the overall convenience of use.

[0022] In this embodiment, a coupling side wall 103 is further provided at the bottom of the heat exchange frame 1. The coupling side wall 103 is adapted to the guiding side wall 32, so that the guiding side wall 32 can be attached to the coupling side wall 103, thereby being able to play a role in positioning the dust-proof frame 3 during the installation process of the dust-proof frame 3 and ensuring that the dust-proof frame 3 is installed in place.

[0023] In summary, after the dust-proof frame 3 is installed, the heat exchange frame 1 is fixed at the use position. Then, the base tube 2 is connected to the compressor. Through the heat medium, heat can be generated in the base tube 2, and the heat can be transferred to the spiral fins 9. And through the external fan, the heat can be blown out from the spiral fins 9, so as to achieve the purpose of air heating. Moreover, when the air enters, the dust in the air can be blocked by the dust-proof metal net 31, thereby preventing dust from entering the interior of the heat exchanger, and thus avoiding the accumulation of dust on the spiral fins 9.

[0024] This specific embodiment is only an interpretation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
