Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heaters, in particular to a heat exchange structure of a heater. Background Art
[0002] In places with relatively large latitudes on the earth, there are more cold days and the temperature is relatively low. When resting outside, heating is generally needed to improve comfort. In ancient times, people mostly used firewood or coal for heating; modern households have various equipment for heating, such as wood-burning and coal-burning stoves, electric tables, and various portable small devices. Electric heaters convert electrical energy into thermal energy, and have the advantages of rapid heating, simple operation, and high safety. They are widely used in small places such as homes and offices. However, traditional electric heaters have some shortcomings during use. First, the heat is unevenly distributed, resulting in uneven indoor temperature distribution, which affects the heating effect. Secondly, some heaters have low thermal efficiency, high energy consumption, and are not environmentally friendly. As for high-power heaters, there are only oil and gas heaters.
[0003] Gas heaters use gas as energy and have the advantages of good heating effect and large heating area. They are suitable for heating needs in large areas. Now many gas heaters use cast iron and cast copper to manufacture the combustion chamber to separate the combustion and heating channels and achieve flue gas separation. However, the production of cast iron and cast copper will make the material thick, the production cost high, and the heat exchange effect poor; or a rough method is used to directly burn the high-temperature gas and discharge part of the high-temperature flue gas, so that the high-temperature flue gas is mixed with the ambient air to increase the temperature. In this way, it can be used outdoors or temporarily used in a room with efficient ventilation. The high-temperature gas may contain a large amount of harmful gases such as CO if it is not completely burned. If the ventilation is not in place and the harmful gases are not discharged in time, it will endanger human life. Utility Model Content
[0004] The purpose of the utility model is to provide a reasonably designed heat exchange structure of a heater in view of the defects and shortcomings of the prior art, which can solve the above-mentioned defects.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises a connected "C"-shaped structural member 1 and a structural member 2, both of which are provided with relative channel grooves, the channel grooves in the structural member 1 and the structural member 2 constitute a double-layer flow channel, and channel connectors are respectively provided at the upper and lower ends of the structural member 2, the two channel connectors are respectively connected to the channel grooves of the structural member 2, and the two channel connectors are connected.
[0006] Preferably, the first structural member and the second structural member are both formed by sheet metal stamping.
[0007] Preferably, the first structural member and the second structural member are connected by riveting.
[0008] Preferably, the first structural member and the second structural member are both made of iron.
[0009] After adopting the above structure, the beneficial effects of the utility model are:
[0010] This device uses sheet metal forming, which is simple and efficient to produce, and the material is evenly distributed. Compared with the old-fashioned technology of die casting, the material thickness is thin, the heat exchange efficiency is high, the heat transfer speed is fast, the iron melting point is high, it is durable and the production cost is low.
[0011] The device uses a double-layer flow channel, so that a temperature difference is naturally generated during the heat exchange process, the air flow is strong, the heat exchange distance of the flue gas is long, and the heat utilization rate is high.
[0012] When the device is in use, the burning gas is separated from the external air, and the waste gas is forced to be discharged without causing poisoning. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 5As shown, it comprises a connected "C"-shaped structural member 1 and a structural member 2, wherein both the structural member 1 and the structural member 2 are provided with relative channel grooves 3, and the channel grooves 3 in the structural member 1 and the structural member 2 constitute a double-layer flow channel, and channel connectors 4 are respectively provided at the upper and lower ends of the structural member 2, and the two channel connectors 4 are respectively connected to the channel grooves 3 of the structural member 2, and the two channel connectors 4 are connected.
[0022] See also Figure 1-Figure 5 As shown, the structural member 1 and the structural member 2 2 are both formed by sheet metal stamping.
[0023] See also Figure 1-Figure 4 As shown, the structural member 1 and the structural member 2 2 are connected by riveting.
[0024] See also Figure 1-Figure 4 As shown, the structural member 1 and the structural member 2 2 are both made of iron.
[0025] The principle and use process of this utility model:
[0026] First, the structural part 1 and the structural part 2 are produced by sheet metal, and the two channel connectors 4 in the structural part 2 are welded, and then the structural part 1 is put on the outside of the structural part 2, and the structural part 1 and the structural part 2 are fixed with rivets after alignment, and the air tightness is tested, and the production is completed;
[0027] When in use, one end of the flow channel is connected to the combustion device of the heater, and the other end of the flow channel is connected to the exhaust device. As the combustion device introduces high-temperature flue gas, the flue gas enters the flow channel and generates heat exchange with structural member 1 and structural member 2. The iron structural members have high heat exchange efficiency, and the flue gas needs to flow through a double-layer flow channel. During the flow, the heat is absorbed, the temperature of the flue gas drops rapidly, and a temperature difference is generated between the upper and lower layers of the flow channel. At the same time, the air temperature outside the heat exchange structure rises rapidly, the hot air rises, and the air below flows passively to generate airflow. An air supply device may also be provided to allow heat to be transmitted more quickly.
