一种可以防水的高温安装辐射加热器

Abstract

本实用新型提供一种可以防水的高温安装辐射加热器，包括壳体、底板、发热件和侧盖板；侧盖板与底板的侧面固定连接，底板的另一侧面开设有插槽；壳体的形状为底部开口的罩体，壳体侧壁的底部向内弯折延伸形成插板，插板插入插槽中，壳体设置为遮盖在侧盖板和底板的上方；壳体、底板和侧盖板之间围成防水内腔，发热件固定设置在防水内腔里；在壳体内表面的两端各涂布有一圈防水胶。本实用新型提出的辐射加热器通过壳体遮盖在侧盖板和底板的上方实现顶面和侧面防水，在壳体内表面两端各涂布一圈防水胶加强侧面防水。即使在辐射加热器倾斜使用的情况下，水流也无法进入防水内腔，而是顺着插槽排出；具有防水、成本低、结构可靠、高温不变形的优点。

Claims

The housing, the bottom plate, and the side cover plate form a waterproof inner cavity, and the heating element is fixedly disposed in the waterproof inner cavity; A ring of waterproof adhesive is applied to each end of the inner surface of the housing.

2. A waterproof high-temperature radiant heater as described in claim 1, characterized in that, The housing includes two side baffles, a top plate, and two side wall plates formed by integral bending. Before bending, the shell is a cross-shaped sheet, wherein the top plate is located in the middle, the two side baffles are located on the left and right sides of the top plate respectively, and the two side wall plates are located on the upper and lower sides of the top plate respectively. The side baffle is bent and then blocks the outside of the side cover plate, and the end of the side wall plate is bent inward again to form an insert plate.

3. A high temperature installation radiant heater that can be waterproofed according to claim 2, characterized in that, The insert plate is parallel to the top plate, and the angle between the side wall plate and the top plate is an obtuse angle to prevent water from flowing into the slot along the side wall plate and the insert plate; the middle part of the side wall plate is bent again to form two sub-plates, and the bent part of the side wall plate arches outward to form a protrusion.

4. A high temperature installation radiant heater that can be waterproofed according to claim 2, characterized in that, The length of the insert plate is less than the length of the side wall plate, and the total length of the bottom plate and the side cover plate is less than the length of the insert plate; the slot passes through the side of the bottom plate, and the side of the side cover plate has a notch that matches the slot; the insert plate is inserted into the slot and the notch; the waterproof adhesive is placed between the upper surface of the insert plate and the slot to prevent water from flowing into the waterproof cavity along the slot.

5. A high temperature installation radiant heater capable of being waterproofed according to claim 2, wherein The height of the insert plate is lower than the height of the bottom of the side baffle, and there is a height difference between the insert plate and the side baffle in the vertical direction, which is used to install the base plate; there is a gap between the end face of the insert plate and the side of the side baffle in the horizontal direction, and the gap is greater than the thickness of the side cover plate, which is used to install the side cover plate.

6. A high temperature installation radiant heater that can be waterproofed according to claim 1, characterized in that, The base plate is shaped like an arc panel, and its cross-section is an arc segment. Multiple heat dissipation grooves are formed on the lower surface of the base plate to increase the heat dissipation area and improve the effect of radiant heating.

7. A high temperature installation radiant heater that can be waterproofed according to claim 2, characterized in that, The heating element is a stainless steel heating tube, and the upper surface of the base plate has a mounting groove arranged along the long side, and the heating element is installed in the mounting groove.

8. A high temperature installation radiant heater that can be waterproofed according to claim 7, characterized in that, The waterproof high-temperature radiant heater also includes bolts and hammer nuts. The hammer nuts are installed in the mounting groove, and the bolts are set on the top plate. The bolts pass through the top plate and are connected to the hammer nuts.

9. A high temperature installation radiant heater that can be waterproofed according to claim 1, characterized in that, The waterproof high-temperature radiant heater also includes an insulation layer disposed in the waterproof inner cavity, the insulation layer being disposed above the heating element; the waterproof adhesive is applied to the space between the side cover plate and the insulation layer.

10. A waterproof high-temperature radiant heater as described in claim 2, characterized in that, The waterproof high-temperature radiant heater also includes a mounting bracket, which is fixedly mounted on the top plate. The mounting bracket has a wire hole, and there is a gap between the wire hole and the top plate to prevent the wire from getting hot.
