Description

Technical Field

[0001] This utility model relates to the field of heat pumps, and more specifically, to a fixing clip and a heat pump. Background Technology

[0002] A heat pump is a device that transfers heat energy from a lower-grade heat source to a higher-grade heat source. In other words, heat can spontaneously transfer from a high-temperature object to a low-temperature object, but not spontaneously in the opposite direction. Heat pumps can effectively utilize hard-to-use low-grade heat energy to achieve energy savings. An electric heating element is installed on the heat pump chassis to heat the chassis and prevent it from freezing in low-temperature environments, thus ensuring the normal operation of the heat pump.

[0003] Electric heating elements are often connected to the heat pump chassis using a movable connection for easy replacement. Currently, most electric heating elements are secured using M-clamps. The M-clamp's shape is similar to the letter M. During use, the middle of the M-clamp is welded to the chassis, and the two sides of the M-clamp hold and secure the electric heating element. Inserting the electric heating element under the M-clamp requires manually prying open the two sides of the M-clamp, which is very laborious and makes it difficult to fit larger electric heating elements into the clamping range, making it very inconvenient to use. Utility Model Content

[0004] This invention provides a fixing clip and a heat pump that can replace the existing M-clamp, overcoming the inconvenience and laborious operation of the M-clamp.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] An embodiment of this utility model provides a fixing clip, which includes:

[0007] The mounting part is used to connect to the chassis of the heat pump;

[0008] The clamping part is connected to the fixing part. The clamping part has a clamping cavity. The opening direction of the clamping cavity is parallel to the chassis surface or the opening direction is towards the side away from the chassis. The clamping cavity is used to clamp the electric heating belt.

[0009] Optionally, the fixing clip also includes a transition portion located between the fixing portion and the clamping portion, and the transition portion is connected to both the fixing portion and the clamping portion.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] The heat pump chassis is equipped with an electric heating element to heat the chassis and prevent it from freezing in low-temperature environments, which would affect the normal operation of the heat pump. The electric heating element is usually connected to the heat pump chassis in a movable manner for easy replacement.

[0036] Currently, most electric heating elements are secured using M-clamps. The M-clamp's shape resembles the letter M. During use, the center of the M-clamp is welded to the base, and the two sides of the M-clamp hold and secure the electric heating element. Inserting the heating element under the M-clamp requires manually prying open the two sides of the clamp and then quickly inserting the heating element, using the M-clamp to hold it in place. This entire operation is very laborious and makes it difficult to fit larger heating elements into the clamping range, making it inconvenient to use. Furthermore, manufacturing the M-clamp requires sheet metal cutting and bending the material into an M shape using a bending machine, generating a significant amount of waste during the process, resulting in high manufacturing costs and numerous steps.

[0037] In view of this, an embodiment of the present invention provides a fixing clip and a heat pump, which can solve the above problems, and will be described in detail below.

[0038] Please refer to Figures 1 to 3The fixing clip 1 includes a fixing part 10 and a clamping part 11. The fixing part 10 is connected to the chassis 2 of the heat pump, and the clamping part 11 is connected to the fixing part 10. The clamping part 11 has a clamping cavity 111. The opening direction of the clamping cavity 111 is parallel to the surface of the chassis 2 or the opening direction is towards the side away from the chassis 2. The clamping cavity 111 clamps the electric heating band 3. Since the opening of the clamping cavity 111 of the fixing clip 1 is parallel to the surface of the chassis 2 or the opening direction is towards the side away from the chassis 2, the electric heating band 3 can be directly inserted into the clamping cavity 111 from the side or top of the clamping part 11. It is not necessary to place the electric heating band 3 under the fixing clip 1, which makes the operation easier and more convenient. It is not necessary to forcefully pry open the two sides of the M-clamp as required by using an M-clamp to insert the electric heating band 3. Similarly, it is easier and more convenient to remove the electric heating band 3 from the fixing clip 1.

[0039] In this embodiment, the opening direction of the clamping cavity 111 of the fixing clamp 1 is related to the position of the chassis 2. For example, when the fixing clamp 1 needs to be set on the horizontally arranged chassis 2, the opening range of the clamping cavity 111 is parallel to the horizontal plane to perpendicular to the horizontal plane, and the opening of the clamping cavity 111 does not face the side where the chassis 2 is located.

[0040] The fixing clamp 1 also includes a transition part 12, which is located between the fixing part 10 and the clamping part 11. The transition part 12 is connected to the fixing part 10 and the clamping part 11 respectively. The transition part 12 serves to connect the fixing part 10 and the clamping part 11 together. Generally, the fixing part 10, the transition part 12 and the clamping part 11 are rigidly connected in sequence to prevent the clamping part 11 from shaking or shifting.

[0041] In this embodiment, the fixing part 10, the clamping part 11, and the transition part 12 are integrally formed to form the fixing clamp 1. The integrally formed fixing clamp 1 is not only easy to manufacture, but also has good uniformity. Force can be transmitted between the fixing part 10 and the transition part 12, as well as between the transition part 12 and the clamping part 11. When the fixing part 10 is fixed, the position of the clamping part 11 is also relatively fixed. The clamping part 11 will not shift, flip, or shake, thereby ensuring the stability of clamping and fixing the electric heating band 3.

[0042] The one-piece molded fixing clip comes in various shapes.

[0043] For example, such as Figure 1The fixing clip 1 is a long strip of thin plate, which is laid flat when connected to the chassis 2. A strip groove 13 is also provided in the middle of the thin plate. The length direction of the strip groove 13 is along the length direction of the thin plate, and the two ends of the strip groove 13 do not penetrate the thin plate. The fixing part 10 is set at any part of the strip groove 13. If the fixing clip 1 is made of metal, the fixing part 10 can be set in the middle of the strip groove 13 and the fixing clip 1 can be welded to the chassis 2 by welding. The opening of the strip groove 13 provides convenient operating space for welding operation and can firmly weld the fixing clip 1 to the chassis 2. If the fixing clip 1 is made of non-metallic material, the fixing part 10 of the fixing clip 1 can also be connected to the chassis 2 by adhesive or screw. When adhesive connection, high viscosity glue needs to be evenly applied to the surface of the chassis 2 and the surface of the fixing part 10. When screw connection, screws or bolts can be used to connect the fixing part 10 to the chassis 2.

[0044] The clamping part 11 is a flexible body and can be bent to form a clamping cavity 111. When it is necessary to clamp the electric heating band 3 through the clamping cavity 111, the electric heating band 3 can be placed on the clamping part 11 first, and then the clamping part 11 can be manually bent to clamp the electric heating band 3 inside the bend of the clamping part 11, thereby fixing the electric heating band 3; of course, the clamping part 11 can also be bent first to form the clamping cavity 111, and then the electric heating band 3 can be inserted into the clamping cavity 111 to fix the electric heating band 3. The shape and size of the clamping cavity 111 need to be adapted to the electric heating band 3 to ensure that the electric heating band 3 will not shake or slip out of the clamping cavity 111 when clamping it.

[0045] Since the clamping part 11 in this embodiment is a thin plate, it is easier to bend and more convenient to use. In other embodiments, the clamping part 11 can also use a clip. The clip can be a product currently available on the market. The electric heating band 3 is clamped by the clip. It should be noted that the electric heating band 3 has a high temperature when it is working, so the selected clip needs to have the characteristics of high temperature resistance.

[0046] In this embodiment, the thin plate-shaped fixing clip 1, compared to the M-clamp, does not require bending into an M-shape using a bending machine, nor does it require cutting the M-clamp, thus saving manufacturing materials and reducing manufacturing processes.

[0047] For example, such as Figure 4The transition part 12 is rod-shaped, the clamping part 11 is plate-shaped, and the fixing part 10 is block-shaped or plate-shaped. The two ends of the rod-shaped transition part 12 are fixedly connected to the fixing part 10 and the clamping part 11, respectively. The plate-shaped clamping part 11 is a flexible body and can be bent to form a clamping cavity 111, which clamps the electric heating band 3. The specific operation is as described above. Alternatively, the clamping part 11 can be a clip to clamp the electric heating band 3; the form of the clip is not limited here. The connection between the fixing part 10 and the chassis 2 can also be achieved through various methods, including welding, adhesive bonding, or screwing or bolting.

[0048] It is worth mentioning that the electric heating band 3 in this embodiment of the utility model is positioned above the fixing clamp 1. Therefore, the area in direct contact between the electric heating band 3 and the chassis 2 is limited. In order to ensure that the electric heating band 3 can transfer heat to the chassis 2 with high efficiency, the fixing clamp 1 is preferably made of a material with excellent thermal conductivity, such as copper or iron.

[0049] Continue to refer to Figures 1 to 4 The number of clamping parts 11 is at least one to clamp the electric heating band 3; and / or the number of fixing parts 10 is at least one to fix the fixing clamp 1 as a whole to the chassis 2.

[0050] Optionally, there is one clamping part 11 and one fixing part 10, with the clamping part 11 and the fixing part 10 located at opposite ends of the transition part 12. One clamping part 11 is clamped at one part of the electric heating belt 3.

[0051] Optionally, there are two clamping parts 11 and one fixing part 10. The two ends of the two transition parts 12 are respectively connected to the fixing part 10 and the corresponding clamping part 11. The two clamping parts 11 can clamp two electric heating bands 3 at the same time or clamp two different parts of the same electric heating band 3.

[0052] In this embodiment, the number of clamping parts 11 and the number of fixing parts 10 are not limited. By arranging more fixing parts 10, the connection of the fixing clamp 1 can be made more secure and stable. By arranging more clamping parts 11, more electric heating bands 3 can be clamped and fixed.

[0053] The fixing clip 1 of this utility model embodiment is simple and effortless to use, and saves materials and manufacturing processes, reduces manufacturing costs, and improves manufacturing efficiency.

[0054] An embodiment of this utility model also provides a heat pump, including a chassis 2 and the aforementioned fixing clamp 1. The fixing part 10 of the fixing clamp 1 is connected to the chassis 2, and the clamping part 11 is used to clamp the electric heating belt 3. The arrangement and number of fixing clamps 1 on the chassis 2 can be designed according to actual needs. If more and denser electric heating belts 3 need to be arranged, more fixing clamps 1 need to be used. Here, the arrangement and number of fixing clamps 1 are not limited. The heat pump has all the functions of the fixing clamp 1.

[0055] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
