Description

Technical Field

[0001] The utility model belongs to the technical field of radiators, and in particular relates to a radiating strip with U-shaped fins and a multi-position PTC radiator thereof. Background Art

[0002] Radiator is an important and basic component in hot water (or steam) heating system. Hot water cools down in the radiator (or steam condenses in the radiator) to provide heat to the room to achieve the purpose of heating. After working for a period of time, the existing PTC radiator needs a long time for the temperature inside the radiator to drop. Therefore, the poor heat dissipation of the radiator will not only cause safety problems such as burns caused by accidental touch by the user, but also greatly affect the overall service life. In addition, the heat dissipation fins inside the existing PTC radiator are generally V-shaped structures. This structure causes the two sides of the heat dissipation fins to be connected to the heat-conducting aluminum strip at points, making the overall fixation not very stable. Therefore, a heat dissipation strip with U-shaped fins and a multi-speed PTC radiator are designed to overcome the above problems. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and to provide a heat dissipation strip with U-shaped fins and a multi-position PTC radiator thereof which has a simple and reasonable structure, high overall strength, firm fixation, good heat dissipation performance, convenient gear adjustment, and long service life.

[0017] In order to enable ordinary technicians in the field to more clearly understand the purpose, technical solutions and advantages of the utility model, the utility model is further explained below in conjunction with the accompanying drawings and embodiments.

[0018] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal" and "vertical" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention. They do not indicate or imply that the device or component referred to must have a specific direction and therefore should not be understood as a limitation on the present invention.

[0019] The utility model will be described in detail below with reference to the accompanying drawings: Figure 1-2 As shown, a heat sink with U-shaped fins comprises a heat sink body, which is composed of a heat-conducting aluminum bar 1 and a fin bar 2 installed on at least one side of the heat-conducting aluminum bar 1. The fin bar 2 is integrally formed or is formed by connecting the two ends of a plurality of U-shaped fins 3 to each other. The upper arc end of the fin bar 2 is fixed on the heat-conducting aluminum bar 1, and a surrounding edge 4 is fixed outside the lower arc end. The two ends of the surrounding edge 4 are provided with a rim 5 perpendicular to the rim 4, the rim 5 is opposite to the two ends of the heat-conducting aluminum bar 1, and a certain heat dissipation gap 6 is left between the rim 5 and the heat-conducting aluminum bar 1. The fin bar 2 is also provided with a heat dissipation window 7.

[0020] The utility model uses a U-shaped fin structure to change the original point connection between the heat dissipation fin and the thermally conductive aluminum strip into a surface connection, which greatly increases the connection area, thereby ensuring a stable connection between the heat dissipation fin and the thermally conductive aluminum strip. In addition, a heat dissipation window is provided on the heat dissipation fin, and a certain heat dissipation gap is left between the edging and the thermally conductive aluminum strip, thereby greatly improving the overall heat dissipation effect.

[0021] like Figure 3 As shown, the U-shaped fin 3 is welded by the upper ends of two mirror-arranged S-shaped heat sinks, and the lower sides of two adjacent U-shaped fins 3 are welded together to form a fin strip 2, and the joint is polished to form an arc-shaped end 8, and a plurality of heat dissipation windows 7 are provided on the side of the S-shaped heat sink. There are two heat dissipation windows 7, which are arranged left and right, and a plurality of heat dissipation blades 9 are arranged on the heat dissipation windows 7, and the heat dissipation blades 9 are arranged obliquely. The inclination direction of the heat dissipation blades 9 on the two heat dissipation windows 7 is arranged oppositely, mirror-arranged, or centrally symmetrically.

[0022] The utility model can have multiple heat dissipation windows, and their specific shapes and positions can be adjusted according to actual conditions without any limitation. The heat dissipation leaves on the heat dissipation windows can greatly improve the overall heat dissipation effect, thereby extending the overall service life.

[0023] A protruding connector 10 is provided at one end of one side of the heat dissipation strip, a connecting terminal 11 is installed on the connector 10, and a mounting through hole 12 is provided on the connecting terminal 11 to facilitate the installation of the cable. Figure 4 and Figure 5 These are two installation methods of the heat sink in the present invention. Of course, the number of heat sinks can be adjusted according to actual conditions without any limitation. The shape of the heat sink can also be bent by a bending machine to form other shapes such as round, polygonal, star-shaped, diamond-shaped, square or special-shaped to meet actual needs.

[0024] The utility model has a connection terminal with a mounting through hole installed at one end of one side of each heat dissipation strip, and realizes multi-speed operation through different wiring methods (connected to an external power supply), thereby ensuring the overall practicality of the utility model and meeting actual needs.

[0026] like Figure 5 As shown, the multi-speed PTC radiator has three speeds of adjustment, wherein the upper three terminals (A, B and C from top to bottom) are used to connect the negative pole, and the last terminal at the bottom (referred to as D for short) is used to connect the positive pole. When CD is connected to the negative pole and the positive pole respectively, it is the first speed, when BD is connected to the negative pole and the positive pole respectively, it is the second speed, and when AD is connected to the negative pole and the positive pole respectively, it is the third speed. The whole process is simple and convenient.
