Abstract

The utility model relates to a heat exchanger for heat pump water heater, which comprises an outer pipe and an inner pipe inside the outer pipe, wherein, each surface of the internal and external walls of the outer pipe and the inner pipe may be provided with a protuberant fin. The utility model has the advantages of simple structure, reasonable design, high heat exchange efficiency, and a fixed reliable insulation layer.

Description

The heat exchanger of Teat pump boiler

Technical field

The utility model relates to a kind of Teat pump boiler, specifically relates to a kind of heat exchanger of Teat pump boiler.

Background technology

The refrigerant pipe and the water pipe surface of the heat exchanger of existing Teat pump boiler all are shiny surfaces, and heat radiation and endothermic effect are poor, because the outer surface of heat exchanger need wrap up heat-insulation layer, smooth surface and heat-insulation layer engagement are not firm, and heat insulation effect is bad.

Summary of the invention

Therefore, the purpose of this utility model is to provide the heat exchanger of a kind of heat radiation and the Teat pump boiler that endothermic effect is good and heat-insulation layer is fixed.

The purpose of this utility model is to realize like this.

A kind of heat exchanger of Teat pump boiler comprises outer tube and the interior pipe that is located at outer tube bore, and the arbitrary surface of the inside and outside wall of described outer tube and interior pipe all can be provided with the fin of projection.

Above-mentioned purpose also can be done further perfect by the following technical programs.

Described fin can axially or radially being provided with along outer tube and interior pipe.

The utility model structural design advantages of simple, the heat exchange efficiency height, heat-insulation layer is fixed.
