Description

Technical Field

[0001] The utility model belongs to the technical field of temperature control methods of heaters and relates to a temperature control box, in particular to a temperature measuring temperature control box installed on a PTC heater, that is, a square tube temperature control box. Background Art

[0002] In the prior art, PTC heaters are widely used, especially in air conditioners. During the use of PTC heaters, the temperature of the heater needs to be detected and controlled; the existing temperature control devices mostly detect air, junction boxes, or heater heat sinks, and there is no temperature control device for measuring and controlling the temperature of the heating tube. Utility Model Content

[0003] In view of the above problems, the utility model aims to provide a square tube temperature control box.

[0004] The technical solution of the utility model is: a square tube temperature control box described in the utility model comprises a temperature control box, and a cover plate is arranged on the front side of the temperature control box.

[0005] Furthermore, a square tube slot is provided at the center of the temperature control box on one side facing the cover plate.

[0006] Furthermore, circular holes are provided at the upper and lower ends of the temperature control box on the side facing the cover plate.

[0007] Furthermore, cover plate fixing holes are provided at the upper and lower ends of the cover plate, corresponding to the circular holes.

[0008] Furthermore, the diameter of the cover plate fixing hole is larger than the diameter of the circular hole.

[0009] Furthermore, a temperature control position is arranged inside the temperature control box.

[0010] Furthermore, the temperature control box is a box-shaped structure, and the volume of one side thereof is adapted to the volume of the cover plate.

[0011] The beneficial effect of the utility model is that the temperature control box is fixed on the heating tube of the PTC heater and is located near the junction box, so as to effectively control the heating temperature of the PTC. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the overall structure of the utility model;

[0013] Figure 2 It is a side view of the utility model;

[0014] In the figure: 1. Temperature control box; 2. Cover plate; 3. Temperature control placement position; 4. Square tube slot; 5. Cover plate fixing hole. DETAILED DESCRIPTION

[0015] The specific technical scheme of the utility model is further described in detail below with reference to specific examples.

[0016] like Figure 1-2 As shown, a square tube temperature control box described in the utility model comprises a temperature control box 1, and a cover plate 2 is arranged on the front side of the temperature control box 1 to facilitate the installation of the temperature control box 1 and the cover plate 2.

[0017] Furthermore, a square tube slot 4 is provided at the center of the temperature control box 1 facing the cover plate 2 .

[0018] Furthermore, circular holes are provided at the upper and lower ends of the temperature control box 1 facing the cover plate 2 .

[0019] Furthermore, cover plate fixing holes 5 are provided at the upper and lower ends of the cover plate 2 corresponding to the circular holes.

[0020] Furthermore, the diameter of the cover plate fixing hole 5 is larger than the diameter of the circular hole.

[0021] Furthermore, a temperature control placement position 3 is arranged inside the temperature control box 1 .

[0022] Furthermore, the temperature control box 1 is a box-shaped structure, and the volume of one side thereof is adapted to the volume of the cover plate 2 .

[0023] The temperature control box 1 of the utility model is fixed on the heating tube of the PTC heater and is located near the junction box, and can effectively control the heating temperature of the PTC.
