Novel cooling device of high-temperature cooling compressor

Abstract

The invention relates to a novel cooling device of a high-temperature cooling compressor. An authentication management module, a service management module, a transaction platform module, a seller client, a buyer client and a dispenser client are included; the seller client, the buyer client and the dispenser client register user accounts in the authentication management module, and the authentication management module authenticates and manages types of the user accounts; the service management module manages different types of serves in a classified way; a seller sells commodities and a buyerbuys commodities in the transaction platform module; and a dispenser receives logistics dispensing information via the dispenser client. Thus, a steel transaction market can be expanded via a networktransaction platform; steel transaction time can be shortened effectively; and via the dispenser client, the dispenser can be authorized by the buyer to dispense the commodity bought by the buyer in the transaction platform to the buyer.

Description

technical field [0001] The invention relates to a network transaction system, in particular to a novel high-temperature cooling compressor refrigeration device. Background technique [0002] At present, some metals and steel products are traded offline without a corresponding trading platform, so that both buyers and sellers cannot know the purchase and sale information of steel products in time, so that the transaction cannot be carried out in time, hindering the development of enterprises and increasing the cost of enterprises , It is not conducive to the working capital of enterprises. In the modern logistics system, the logistics volume shows a linear upward trend with the development of city size and population. In addition, in the steel trading system, users often do not participate in the transaction on the spot. After the transaction is completed, the delivery of goods needs to be completed by a third-party freight forwarder, which involves the reliability of the th...
