Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a dual-mode heat exchanger. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers heat between two or more fluids at different temperatures. It is widely used in chemical, petroleum, power, food and many other industrial productions.

[0003] For heat exchangers, flow resistance and heat transfer performance need to be considered based on actual needs. In order to improve heat transfer efficiency, high heat exchangers need to increase the heat transfer area, which leads to increased flow resistance. In order to reduce flow resistance, low flow resistance heat exchangers have to sacrifice the heat transfer area, resulting in reduced heat transfer performance. This results in the heat exchanger either having high heat transfer and high flow resistance, or low heat transfer and low flow resistance. It is impossible to switch between high heat transfer and low flow resistance according to actual usage needs, and the use is not flexible enough. Therefore, a dual-mode heat exchanger is needed.

[0026] Reference Figure 1-Figure 4 , is an embodiment of the utility model, and provides a dual-mode heat exchanger, which includes:

[0027] The main body 100 includes a heat exchange chamber 101, in which two sets of mounting plates 102 are arranged, and the side walls of the two sets of mounting plates 102 are fixedly connected to the inner wall of the heat exchange chamber 101, and a spiral plate 103 is arranged between the two sets of mounting plates 102, and the two sides of the spiral plate 103 are respectively fixedly connected to the two sets of mounting plates 102, and the side walls of the spiral plate 103 are fixedly connected to the inner wall of the heat exchange chamber 101, and a plurality of groups of heat exchange tubes 103 are also arranged between the two sets of mounting plates 102. 04, several groups of heat exchange tubes 104 are fixedly connected to the spiral plate 103 and the two groups of mounting plates 102, and several groups of heat exchange tubes 104 penetrate the spiral plate 103 and the two groups of mounting plates 102. The side wall of the heat exchange chamber 101 is also fixedly connected with an air inlet pipe 105 and an air outlet pipe 106. The heat exchange chamber 101, the spiral plate 103 and the two groups of mounting plates 102 form a spiral chamber, and the air inlet pipe 105 and the air outlet pipe 106 are respectively located at the two side ends of the spiral chamber;

[0028] The switching mechanism 200 includes a three-way valve 201, which is fixedly connected to the air inlet pipe 105. The three-way valve 201 is also fixedly connected to a connecting pipe 202. One end of the connecting pipe 202 away from the three-way valve 201 is fixedly connected to the side wall of the heat exchange chamber 101 and is directly opposite to the air outlet pipe 106.

[0029] Among them, the main body 100 also includes two groups of supports 107, and the two groups of supports 107 are fixedly connected to the bottom of the heat exchange chamber 101. The two groups of supports 107 are used to support the device. The two groups of supports 107 are located close to both sides of the heat exchange chamber 101 to maximize the supporting area, which is conducive to ensuring a stable supporting device. The surfaces of the two groups of supports 107 are coated with anti-corrosion paint, which is used to prevent the supports 107 from rusting.

[0030] It should be noted that several groups of heat exchange tubes 104 are evenly distributed, which is beneficial to improving the heat exchange performance. The heat exchange bin 101, the mounting plate 102, the spiral plate 103 and the heat exchange tubes 104 are all made of stainless steel materials. Stainless steel materials are corrosion-resistant. The outer wall of the heat exchange bin 101 is also coated with anti-corrosion paint. The anti-corrosion paint is used to further improve the anti-corrosion performance of the heat exchange bin 101.

[0031] Working principle: cold air enters the heat exchange chamber 101 from one end away from the air inlet pipe 105, passes through several groups of mounting plates 102 and is output from the other end of the heat exchange chamber 101;

[0032] like Figure 2 As shown, the three-way valve 201 is turned to connect the three-way valve 201 with the air inlet pipe 105, and the hot air passes through the three-way valve 201 and the air inlet pipe 105 in sequence and then enters the heat exchange chamber 101, and then passes through the spiral chamber formed by the heat exchange chamber 101, the spiral plate 103 and the two sets of mounting plates 102 and is output from the air outlet pipe 106. The cold air and the hot air complete the heat exchange through the spiral plate 103 and the heat exchange pipe 104. The spiral chamber increases the hot air travel and the heat exchange area at the same time, which is a high heat exchange mode.

[0033] like Figure 3 As shown, the three-way valve 201 is rotated to connect the three-way valve 201 with the connecting pipe 202, and the hot gas passes through the three-way valve 201 and the connecting pipe 202 in sequence and then enters the heat exchange chamber 101, and then passes through the gaps between several groups of spiral plates 103 and is output from the outlet pipe 106. Compared with the hot gas being introduced through the inlet pipe 105, the hot gas travel distance is shortened and the hot gas travel resistance is reduced, thus achieving a low flow resistance mode.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
