Description

Technical Field

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

[0002] A heat exchanger is an energy-saving device used to achieve heat transfer between two or more fluids of different temperatures, helping heat to be transferred from a higher temperature fluid to a lower temperature fluid, ultimately making the fluid temperature reach a preset index to meet the needs of a specific process flow. At the same time, a heat exchanger is also one of the important devices for improving energy utilization. According to the structural characteristics, heat exchangers are mainly divided into U-tube sheet heat exchangers, plate heat exchangers and other types.

[0003] When the existing heat exchanger has poor heat exchange effect, it is usually necessary to install multiple heat exchangers in combination to achieve a more efficient heat exchange effect. However, the existing combined heat exchangers can usually only be fixedly connected through connecting pipes. This connection method will cause a large space to be occupied, which brings certain limitations to practical applications. In addition, the existing heat exchangers are usually directly connected to the water inlet pipe, but lack a filtering device. When the local water quality is hard, scale is easily generated during the heating process, thereby affecting the heat exchange efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a combined heat exchanger, comprising a heat exchange box, a first clamping groove and a first clamping block, the first clamping groove is opened on one side of the heat exchange box, the first clamping groove is fixedly connected to the first clamping block on the side of the heat exchange box away from the first clamping groove, a threaded hole is opened at the fitting position of the first clamping groove and the first clamping block, the first clamping groove and the first clamping block are fixed by screw threads, and a detachable connecting pipe is installed on the side of the heat exchange box.

[0006] Preferably, a second clamping block is fixedly connected to the upper end of the heat exchange box body, a second clamping groove is provided at the bottom end of the heat exchange box body, and the second clamping block and the second clamping groove are fixed by screws.

[0007] Preferably, a water inlet and a water outlet are respectively provided on the front side of the heat exchange box, and filter plates are installed in the water inlet and the water outlet.

[0009] Preferably, one end of the connecting pipe is fixedly connected to a connecting head, a connecting block is installed in the connecting head, and the connecting block is provided with the same number of slots as the number of the clamping blocks.

[0010] Preferably, a sealing ring is installed on the connecting head.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0012] First, the utility model can quickly install a combined heat exchanger by setting a first clamping groove and a first clamping block. The first clamping groove and the first clamping block are tightly fitted or the second clamping groove and the second clamping joint are tightly fitted and fixed by screws to achieve the effect of installing a heat exchange box, while reducing the occupation of the site, making the connection positions of multiple heat exchange boxes more flexible, saving space, and reducing the space limitations of the combined heat exchanger.

[0013] Second, the utility model can quickly install the connecting pipe by setting the connecting pipe and the clamping block, connect multiple heat exchange boxes through the connecting pipe, and when the water inlet is in close contact with the connecting head, push the clamping block to move inward. When the clamping block moves to the top of the card slot, the elastic member pushes the clamping block to fit closely with the card slot to achieve preliminary fixation. At this time, the screws are tightened by manpower to fix it, which reduces the time for workers to install the connecting pipe and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
