Problems solved by technology

The disadvantage is that in this heating method, the water vapor fills the cylinder body, the temperature is as high as 160°C and has a relatively high pressure, and the liquid also has a certain pressure when flowing in the heating tube, so once the heating tube cracks, the water vapor will seep into it. In the heated tube, which affects the quality of the dyed cloth
In view of this, some companies are also changing steam heating to pressure-circulating heat-conducting oil heating, but the problem is: once there is a crack in the heating pipe, the liquid will seep out and contact the hot oil, which will cause the hot oil to boil and cause waste.

Embodiment 1

[0011] Embodiment 1: As shown in Fig. 1, Fig. 2 and Fig. 4, the present invention is a pressureless high-temperature heat transfer heat exchanger, comprising a cylinder 1, in which a heat transfer tube 2 and a heat receiving tube 3 are arranged, and the heat transfer The tube 2 passes through the cylinder body 1 through the liquid inlet channel 9 and the liquid outlet channel 10, and the front and rear ends of the heated tube 3 respectively adopt a sleeve structure to pass through the liquid inlet channel 9, the liquid outlet channel 10 and then pass through the two side walls of the cylinder body 1, A heat source such as high-temperature heat-conducting oil flows in the heat transfer tube 2, a heated liquid flows in the heat receiving tube 3, and metal cooling fins 5 are arranged in the cylinder body 1. The heat transfer tube 2 and the heat receiving tube 3 are arranged at intervals and pass through the metal for heat dissipation. Sheet 5, cylinder body 1 is filled with high t...

Embodiment 2

[0012] Embodiment 2: As shown in Figure 3, the basic structure of this example is the same as that of Embodiment 1, and the difference from the previous example is that the heat transfer tubes 2 and the heat receiving tubes 3 are arranged at intervals in layers, and after the heat receiving tubes 3 pass through the phase plate, It only needs to pass through the two side walls of the cylinder body 1 without passing through the liquid inlet channel 9 and the liquid outlet channel 10 first.

[0013] The working principle of the present invention: the heated liquid flows in the heated tube 3, and the heat source flows in the heat transfer tube 2 at the same time. On the one hand, heat is transferred to the liquid to be heated in the heat receiving tube 3 by convective heat transfer through the intermediate transitional high temperature resistant heat transfer medium, so that the liquid to be heated in the heat receiving tube 3 achieves the effect of rapid heating. After heating, t...

Abstract

The present invention discloses heat exchanger, and especially a kind of reinforced pressure-less high-temperature heat exchanger. The reinforced pressure-less high-temperature heat exchanger includes barrel, heat transmitting tubes with heat source and heat accepting tubes with heated liquid inside the barrel, and heat dissipating metal fins arranged inside the barrel. The heat transmitting tubes and the heat accepting tubes are arranged alternately through the heat dissipating metal fins, and high temperature medium is filled inside the barrel. The present invention has reasonable structure, and can avoid the mixing of heating liquid and heated liquid in case of leakage.

Description

1. Technical field [0001] The invention discloses a heat exchanger, in particular discloses a pressureless high-temperature heat transfer heat exchanger, which is suitable for heating in the textile printing and dyeing industry and the chemical industry. 2. Background technology [0002] At present, the heat exchangers used in dyeing machines in the printing and dyeing industry are generally heated indirectly by steam. The two ends of the heat pipe respectively pass through the barrel and connect with the relevant parts on the dyeing machine, and the liquid in the heat pipe is heated by steam and then transported to the dyeing machine for work. The disadvantage is that in this heating method, the water vapor fills the cylinder body, the temperature is as high as 160°C and has a relatively high pressure, and the liquid also has a certain pressure when flowing in the heating tube, so once the heating tube cracks, the water vapor will seep into it. In the heated tube, thus aff...
