A modular tube-sheet heat exchanger and heat exchanging method thereof

Abstract

The invention relates to a modular tube sheet heat exchanger and a heat exchange method thereof. The heat exchanger comprises a cold and heat source generation part, a cold and heat absorption part and an isolation and conduction part. The cold and heat source generation part and the cold and heat absorption part are mutually independently arranged. The isolation and conduction part is arranged between the cold and heat source generation part and the cold and heat absorption part in an isolated mode. A first medium providing cold and heat sources circularly flows in the cold and heat source generation part and heat of the first medium is synchronously conducted into the isolation and conduction part. Then the heat is conducted to a second medium circularly flowing in the cold and heat absorption part by means of the isolation and conduction part, so that heat transfer between the first medium in the cold and heat source generation part and the second medium in the cold and heat absorption part is achieved.

Description

technical field [0001] The present invention relates to a heat exchanger and a heat exchange method thereof, in particular to a heat exchanger comprising a cold and heat source generating part, a cold and heat absorbing part and an isolated conduction part, wherein the cold and heat source generating part is connected to the cold and heat The absorbing parts are arranged independently of each other, and the isolated conduction part is isolated between the cold and heat source generating part and the cold and heat absorbing part, the first medium providing the cold and heat source circulates in the cold and heat source generating part, and simultaneously Its heat is conducted to the isolated conduction part, and then the heat is conducted by the isolated conduction part to the second medium circulating in the cold and heat absorbing part, so that the first medium and the first medium in the cold and heat source generating part Heat transfer between the second medium in the cold...

Problems solved by technology

[0002] As we all know, in the food, pharmaceutical and chemical industries, there are many processes that need to cool or heat a raw material (liquid or gas) to a certain temperature before use, and the carrier of the cold source or heat source and the raw material In the case of different substances, the existing heat exchanger system is to pass the raw material into a device (such as a pipeline) that can transfer heat, and then put the device that feeds the raw material into a cold source or heat source. In the device of the carrier (such as a larger pipeline or vessel), the heat exchange is carried out through the heat transfer of the outer wall of the device that is passed into the raw material, or the position is reversed, but in the above heat exchanger system, once it is relied on Damage to the outer wall of the hot device will cause mutual contamination between the raw material and the cold and heat source carrier due to leakage, which will cause unexpected serious consequences, and this is the main shortcoming of the traditional technology
